Latin输入法怎么默认勾选几种语言

Latin输入法怎么默认勾选几种语言

[DESCRIPTION]

Latin输入法怎么默认勾选几种语言，Latin IME 不使用系统默认的语言

[SOLUTION]

【GB】

提供简单的sample code，如默认将俄语、英文、法语输入法勾选：

1.新增文件LatinImeReceiver.JAVA

package com.android.inputmethod.latin;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.content.SharedPreferences;

import android.content.SharedPreferences.Editor;

import android.preference.PreferenceManager;

import android.provider.Settings;

import android.util.Log;

import android.view.inputmethod.InputMethodInfo;

import android.view.inputmethod.InputMethodManager;

//import android.view.inputmethod.InputMethodSubtype;

import android.text.TextUtils;

public class LatinImeReceiver extends BroadcastReceiver {

private static final String TAG = LatinImeReceiver.class.getSimpleName();

@Override

public void onReceive(Context context, Intent intent) {

Log.d("LatinImeReceiver", "step1");

SharedPreferences sp = context.getSharedPreferences("com.android.inputmethod.latin_preferences",

Context.MODE_PRIVATE);

boolean hasSet = sp.getBoolean("has_set", false);

if (!hasSet) {

Log.d("LatinImeReceiver", "step2");

Editor editor = sp.edit();

Log.d("LatinImeReceiver", "step3");

editor.putString(LatinIME.PREF_SELECTED_LANGUAGES, "en_US,ru,fr"); //默认将英语、俄语勾选，具体该怎么写

可以参考inputlanguageselection.java中的WHITELIST_LANGUAGES

editor.putBoolean("has_set", true);

Log.d("LatinImeReceiver", "step4");

//editor.commit();

SharedPreferencesCompat.apply(editor);

Log.d("LatinImeReceiver", "step5");

}

}

将其放置到路径packages/inputmethods/LatinIME/java/src/com/android/inputmethod/latin文件夹下面

2.注册intent，在packages/inputmethods/LatinIME/java/androidManifest.xml中增加

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

权限

并在最后面加入LatinImeReceiver：

<receiver android:name="LatinImeReceiver" android:enabled="true">

<intent-filter>

<action android:name="android.intent.action.BOOT_COMPLETED" />

</intent-filter>

</receiver>

3 重新编译整个工程

【ICS】

1.在mediatek/config/{projectname}/ProjectConfig.mk中修改如下的config,只需要把默认的语言加在后边即可

DEFAULT_LATIN_IME_LANGUAGES = en_US hi

DEFAULT_LATIN_IME_LANGUAGES后面的格式需要与packages\inputmethods\LatinIME\java\res\xml\method.xml中的

android:imeSubtypeLocale="XXX"字符相匹配，后面添加的语言要与“XXX”相同，例如如果要加印度语言

DEFAULT_LATIN_IME_LANGUAGES = en_US hi 中间用空格隔开。这个后面的格式与MTK_PRODUCT_LOCALES不一样，

MTK_PRODUCT_LOCALES后面是系统的语言以及要编译到系统中的资源的配置。

2.在LatinIMEReceiver.java中 setDefaultSubtypes函数中增加红色部分

private void setDefaultSubtypes(Context context) {

final String serviceName = "com.android.inputmethod.latin/.LatinIME";

final String currentPackageName = "com.android.inputmethod.latin";

final String enable = Settings.Secure.getString(context.getContentResolver(),

Settings.Secure.ENABLED_INPUT_METHODS);

final InputMethodManager imm = (InputMethodManager) context.getSystemService(

Context.INPUT_METHOD_SERVICE);

final StringBuilder builder = new StringBuilder();

// Get sub type hash code

for (InputMethodInfo info : imm.getInputMethodList()) {

if (currentPackageName.equals(info.getPackageName())) {

for (int i = 0; i < info.getSubtypeCount(); i++) {

final InputMethodSubtype subtype = info.getSubtypeAt(i);

final String locale = subtype.getLocale().toString();

if (isDefaultLocale(locale)) {

Log.i(TAG, "default enabled subtype locale = " + locale);

builder.append(';');

builder.append(subtype.hashCode());

}

}

break;

}

}

// Insert the sub type

if (builder.length() > 0 && !TextUtils.isEmpty(enable)) {

final String subtype = builder.toString();

builder.setLength(0);

final int index = enable.indexOf(serviceName) + serviceName.length();

if (enable.length() > index) {

builder.append(enable.substring(0, index));

builder.append(subtype);

builder.append(enable.substring(index));

} else if (enable.length() == index) {

builder.append(enable);

builder.append(subtype);

} else {

return;

}

} else {

Log.w(TAG, "Build Latin IME subtype failed: " + " builder length = " + builder.length()

+ "; enable isEmpty :" + TextUtils.isEmpty(enable));

return;

}

// Commit the result

android.provider.Settings.Secure.putString(context.getContentResolver(),

android.provider.Settings.Secure.ENABLED_INPUT_METHODS, builder.toString());

String lastInputMethodId = Settings.Secure.getString(context

.getContentResolver(), Settings.Secure.DEFAULT_INPUT_METHOD);

Log.w(TAG, "DEFAULT_INPUT_METHOD = " + lastInputMethodId);

if(lastInputMethodId.equals(serviceName)) {

Log.w(TAG, "DEFAULT_INPUT_METHOD = com.android.inputmethod.latin/.LatinIME" );

for (InputMethodInfo info : imm.getInputMethodList()) {

if (currentPackageName.equals(info.getPackageName())) {

for (int i = 0; i < info.getSubtypeCount(); i++) {

final InputMethodSubtype subtype = info.getSubtypeAt(i);

final String[] locales = IMEFeatureOption.DEFAULT_LATIN_IME_LANGUAGES;

Log.w(TAG, "i = " + i + ", locales[0] = " + locales[0]);

if((subtype.getLocale()).equals(locales[0])) {

Log.w(TAG, "putString " + subtype.hashCode());

android.provider.Settings.Secure.putInt(context.getContentResolver(),

android.provider.Settings.Secure.SELECTED_INPUT_METHOD_SUBTYPE, subtype.hashCode());

}

}

break;

}

}

}

}

【JB、KK】

JB中DEFAULT_LATIN_IME_LANGUAGES config没有用到，没有LatinIMEReceiver.java这个文件。所以要默认勾选多种语

言需要参照ICS的做法增加以下部分：

比如默认选中泰语和英语：

1.增加LatinImeReceiver.java文件放在packages\inputmethods\LatinIME\java\src\com\android\inputmethod\latin

目录下

package com.android.inputmethod.latin;

import com.mediatek.common.featureoption.IMEFeatureOption;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.content.SharedPreferences;

import android.provider.Settings;

import android.util.Log;

import android.view.inputmethod.InputMethodInfo;

import android.view.inputmethod.InputMethodManager;

import android.view.inputmethod.InputMethodSubtype;

import android.text.TextUtils;

public class LatinImeReceiver extends BroadcastReceiver {

private static final String TAG = LatinImeReceiver.class.getSimpleName();

@Override

public void onReceive(Context context, Intent intent) {

// Set the default input language at the system boot completed.

if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {

SharedPreferences sp = context.getSharedPreferences("default_input_language_config",

Context.MODE_PRIVATE);

boolean hasSet = sp.getBoolean("has_set", false);

if (!hasSet) {

setDefaultSubtypes(context);

sp.edit().putBoolean("has_set", true).commit();

}

}

}

/**

* M: Set the default IME subtype.

*/

private void setDefaultSubtypes(Context context) {

final String serviceName = "com.android.inputmethod.latin/.LatinIME";

final String currentPackageName = "com.android.inputmethod.latin";

final String enable = Settings.Secure.getString(context.getContentResolver(),

Settings.Secure.ENABLED_INPUT_METHODS);

final InputMethodManager imm = (InputMethodManager) context.getSystemService(

Context.INPUT_METHOD_SERVICE);

final StringBuilder builder = new StringBuilder();

// Get sub type hash code

for (InputMethodInfo info : imm.getInputMethodList()) {

if (currentPackageName.equals(info.getPackageName())) {

for (int i = 0; i < info.getSubtypeCount(); i++) {

final InputMethodSubtype subtype = info.getSubtypeAt(i);

final String locale = subtype.getLocale().toString();

if (isDefaultLocale(locale)) {

Log.i(TAG, "default enabled subtype locale = " + locale);

builder.append(';');

builder.append(subtype.hashCode());

}

}

break;

}

}

// Insert the sub type

if (builder.length() > 0 && !TextUtils.isEmpty(enable)) {

final String subtype = builder.toString();

builder.setLength(0);

final int index = enable.indexOf(serviceName) + serviceName.length();

if (enable.length() > index) {

builder.append(enable.substring(0, index));

builder.append(subtype);

builder.append(enable.substring(index));

} else if (enable.length() == index) {

builder.append(enable);

builder.append(subtype);

} else {

return;

}

} else {

Log.w(TAG, "Build Latin IME subtype failed: " + " builder length = " + builder.length()

+ "; enable isEmpty :" + TextUtils.isEmpty(enable));

return;

}

// Commit the result

android.provider.Settings.Secure.putString(context.getContentResolver(),

android.provider.Settings.Secure.ENABLED_INPUT_METHODS, builder.toString());

String lastInputMethodId = Settings.Secure.getString(context

.getContentResolver(), Settings.Secure.DEFAULT_INPUT_METHOD);

Log.w(TAG, "DEFAULT_INPUT_METHOD = " + lastInputMethodId);

if(lastInputMethodId.equals(serviceName)) {

Log.w(TAG, "DEFAULT_INPUT_METHOD = com.android.inputmethod.latin/.LatinIME" );

for (InputMethodInfo info : imm.getInputMethodList()) {

if (currentPackageName.equals(info.getPackageName())) {

for (int i = 0; i < info.getSubtypeCount(); i++) {

final InputMethodSubtype subtype = info.getSubtypeAt(i);

final String[] locales = IMEFeatureOption.DEFAULT_LATIN_IME_LANGUAGES;

Log.w(TAG, "i = " + i + ", locales[0] = " + locales[0]);

if((subtype.getLocale()).equals(locales[0])) {

Log.w(TAG, "putString " + subtype.hashCode());

android.provider.Settings.Secure.putInt(context.getContentResolver(),

android.provider.Settings.Secure.SELECTED_INPUT_METHOD_SUBTYPE, subtype.hashCode());

}

}

break;

}

}

}

}

/**

* M: Check if the current locale is default or not.

*/

private boolean isDefaultLocale (String locale) {

final String[] locales = IMEFeatureOption.DEFAULT_LATIN_IME_LANGUAGES;

for (String s : locales) {

if (s.equals(locale)) {

return true;

}

}

return false;

}

}

2.修改packages/inputmethods/latinime/java/androidmanifest.xml文件，在此文件中增加LatinImeReceiver的申明

，

<receiver android:name="LatinImeReceiver" android:enabled="true">

<intent-filter>

<action android:name="android.intent.action.BOOT_COMPLETED" />

</intent-filter>

</receiver>

并增加下面3个权限

<uses-permission android:name="android.permission.WRITE_SETTINGS" />

<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

改动如下：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

coreApp="true"

package="com.android.inputmethod.latin">

<uses-permission android:name="android.permission.VIBRATE"/>

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

<uses-permission android:name="android.permission.READ_USER_DICTIONARY" />

<uses-permission android:name="android.permission.READ_CONTACTS" />

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

<uses-permission android:name="android.permission.WRITE_SETTINGS" />

<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />

<application android:label="@string/aosp_android_keyboard_ime_name"

android:icon="@drawable/ic_ime_settings"

android:backupAgent="BackupAgent"

android:killAfterRestore="false">

<service android:name="LatinIME"

android:label="@string/aosp_android_keyboard_ime_name"

android:permission="android.permission.BIND_INPUT_METHOD">

<intent-filter>

<action android:name="android.view.InputMethod" />

</intent-filter>

<meta-data android:name="android.view.im" android:resource="@xml/method" />

</service>

<service android:name=".spellcheck.AndroidSpellCheckerService"

android:label="@string/spell_checker_service_name"

android:permission="android.permission.BIND_TEXT_SERVICE">

<intent-filter>

<action android:name="android.service.textservice.SpellCheckerService" />

</intent-filter>

<meta-data android:name="android.view.textservice.scs" android:resource="@xml/spellchecker" />

</service>

<activity android:name="SettingsActivity" android:label="@string/english_ime_settings"

android:uiOptions="splitActionBarWhenNarrow">

<intent-filter>

<action android:name="android.intent.action.MAIN"/>

</intent-filter>

</activity>

<activity android:name="com.android.inputmethod.latin.spellcheck.SpellCheckerSettingsActivity"

android:label="@string/android_spell_checker_settings">

<intent-filter>

<action android:name="android.intent.action.MAIN"/>

</intent-filter>

</activity>

<activity android:name="DebugSettingsActivity" android:label="@string/english_ime_debug_settings">

<intent-filter>

<action android:name="android.intent.action.MAIN"/>

</intent-filter>

</activity>

<receiver android:name="SuggestionSpanPickedNotificationReceiver" android:enabled="true">

<intent-filter>

<action android:name="android.text.style.SUGGESTION_PICKED" />

</intent-filter>

</receiver>

<receiver android:name="LatinImeReceiver" android:enabled="true">

<intent-filter>

<action android:name="android.intent.action.BOOT_COMPLETED" />

</intent-filter>

</receiver>

</application>

</manifest>

3. 还需要在packages/inputmethods/latinime/java/Android.mk文件当中加入LOCAL_JAVA_LIBRARIES := mediatekcommon

才能编译通过；

4. 在packages\apps\Settings\src\com\android\settings\inputmethod\InputMethodAndSubtypeUtil.java文档中的

updateSubtypesPreferenceChecked函数中把break改为continue。

5.在mediatek/config/{projectname}/ProjectConfig.mk中修改如下的config,只需要把默认的语言写在在后边即可

DEFAULT_LATIN_IME_LANGUAGES = hi en_US 其中第一个语言即为默认的输入语言

DEFAULT_LATIN_IME_LANGUAGES后面的格式需要与packages\inputmethods\LatinIME\java\res\xml\method.xml中的

android:imeSubtypeLocale="XXX"字符相匹配，后面添加的语言要与“XXX”相同，例如如果要加印度语言

DEFAULT_LATIN_IME_LANGUAGES = en_US hi 中间用空格隔开。这个后面的格式与MTK_PRODUCT_LOCALES不一样，

MTK_PRODUCT_LOCALES后面是系统的语言以及要编译到系统中的资源的配置。

6.KK的版本还需要增加以下修改：

修改Latin\java的Android.mk，增加LOCAL_PRIVILEGED_MODULE := true

再重新new整个工程，烧机后就可以看到效果。谢谢

【L版本】

（1）新增加一个LatinImeRe.java文件

放在packages\inputmethods\LatinIME\java\src\com\android\inputmethod\latin目录下

文件内容如下：

package com.android.inputmethod.latin;

import android.content.BroadcastReceiver;

import android.content.Context;

import android.content.Intent;

import android.content.SharedPreferences;

import android.provider.Settings;

import android.util.Log;

import android.view.inputmethod.InputMethodInfo;

import android.view.inputmethod.InputMethodManager;

import android.view.inputmethod.InputMethodSubtype;

import android.text.TextUtils;

public class LatinImeRe extends BroadcastReceiver {

private static final String TAG = "LatinImeRe";

@Override

public void onReceive(Context context, Intent intent) {

// Set the default input language at the system boot completed.

if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {

Log.w(TAG, "onReceive");

SharedPreferences sp = context.getSharedPreferences("default_input_language_config",

Context.MODE_PRIVATE);

boolean hasSet = sp.getBoolean("has_set", false);

setDefaultSubtypes(context);

sp.edit().putBoolean("has_set", true).commit();

}

}

/**

* M: Set the default IME subtype.

*/

private void setDefaultSubtypes(Context context) {

final String serviceName = "com.android.inputmethod.latin/.LatinIME";

final String currentPackageName = "com.android.inputmethod.latin";

final String enable = Settings.Secure.getString(context.getContentResolver(),

Settings.Secure.ENABLED_INPUT_METHODS);

Log.w(TAG, "setDefaultSubtypes() enable :" + enable);

final InputMethodManager imm = (InputMethodManager) context.getSystemService(

Context.INPUT_METHOD_SERVICE);

final StringBuilder builder = new StringBuilder();

// Get sub type hash code

for (InputMethodInfo info : imm.getInputMethodList()) {

if (currentPackageName.equals(info.getPackageName())) {

for (int i = 0; i < info.getSubtypeCount(); i++) {

final InputMethodSubtype subtype = info.getSubtypeAt(i);

final String locale = subtype.getLocale().toString();

//winny

Log.w(TAG, "subtype.getLocale().toString :" + locale);

if (isDefaultLocale(locale)) {

Log.i(TAG, "default enabled subtype locale = " + locale);

builder.append(';');

builder.append(subtype.hashCode());

}

}

break;

}

}

Log.w(TAG, "after for loop :" + builder.toString());

// Insert the sub type

if (builder.length() > 0) {

final String subtype = builder.toString();

builder.setLength(0);

final int index = enable.indexOf(serviceName) + serviceName.length();

if (enable.length() > index) {

builder.append(enable.substring(0, index));

builder.append(subtype);

builder.append(enable.substring(index));

} else if (enable.length() == index) {

builder.append(enable);

builder.append(subtype);

} else {

return;

}

}

// Commit the result

android.provider.Settings.Secure.putString(context.getContentResolver(),

android.provider.Settings.Secure.ENABLED_INPUT_METHODS, builder.toString());

}

/**

* M: Check if the current locale is default or not.

*/

private boolean isDefaultLocale (String locale) {

String[] locales= new String[]{"th","fr"};

//将默认的语言在此添加，注意写法与method.xml中的subtype语言保持一致，这里th和fr是泰语和

法语的示例。

for (String s : locales) {

if (s.equals(locale)) {

return true;

}

}

return false;

}

}

（2）修改packages/inputmethods/latinime/java/androidmanifest.xml文件，在此文件中增加

LatinImeRe的申明

<receiver android:name="LatinImeRe" android:enabled="true">

<intent-filter>

<action android:name="android.intent.action.BOOT_COMPLETED" />

</intent-filter>

</receiver>

并增加下面2个权限

<uses-permission android:name="android.permission.WRITE_SETTINGS" />

<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />

（3）在packages/inputmethods/latinime/java/android.xml中修改LOCAL_CERTIFICATE :=

platform，增加LOCAL_PRIVILEGED_MODULE := true ，之后make new编译整个工程。
