Android中铃声总结【安卓源码解析一】

文章出处：http://blog.csdn.net/wdaming1986/article/details/6919653

最近研究源码程序，改了改手机短信铃声的源码，最近总结了下铃声的代码，写个activity继承PreferenceActivity有：手机短信铃声，手机铃声，闹钟铃声，还有sdcard中的铃声，通过选择相应的铃声，然后读取到xml文件里面，通过读取preference.xml文件，intent传个参数进去intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI,
phoneUri);打开对话框的时候就默认选中上次被选中的音乐。程序流程：在onCreate（）方法中加入addPreferencesFromResource(R.xml.preferences);加载xml文件。@Override重写onPreferenceTreeClick（）方法，处理点击事件，在打开对话框铃声的时候，先读取xml文件，判断是否有值，如果有值，就传值intent.putExtra(RingtoneManager.EXTRA_RINGTONE_EXISTING_URI, phoneUri);然后进行选择铃声。通过onActivityResult（）接受传递过来的uri，系统默认的铃声是通过data.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);方法来获取uri的，而sdcard中的铃声通过Uri
pickedUri = data.getData();来获得选中的uri的，再然后通过editor.commit(); 来提交接受过来的uri和音乐的名字整个流程大概就是这样。想要代码的请留言留下邮箱！

二、在res目录下加入xml文件，加入preferences.xml中的代码：

[html] view
plaincopyprint?

<span style="font-size:16px;"><?xml version="1.0" encoding="utf-8"?>

<PreferenceScreen

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

<PreferenceCategory android:title="@string/pref_sounds_storage_title"

android:key="pref_key_storage_settings">

<Preference

android:layout="?android:attr/preferenceLayoutChild"

android:key="pref_sms_ringtone"

android:ringtoneType="notification"

android:title="@string/pref_title_notification_ringtone"

android:summary="@string/pref_summary_notification_ringtone"

/>

<Preference

android:layout="?android:attr/preferenceLayoutChild"

android:key="pref_phone_ringtone"

android:ringtoneType="notification"

android:title="@string/pref_title_phone_ringtone"

android:summary="@string/pref_summary_phone_ringtone"

/>

<Preference

android:layout="?android:attr/preferenceLayoutChild"

android:key="pref_alarm_ringtone"

android:ringtoneType="notification"

android:title="@string/pref_title_alarm_ringtone"

android:summary="@string/pref_summary_alarm_ringtone"

/>

<Preference

android:layout="?android:attr/preferenceLayoutChild"

android:key="pref_sdcard_ringtone"

android:ringtoneType="notification"

android:title="@string/pref_title_sdcard_ringtone"

android:summary="@string/pref_summary_sdcard_ringtone"

/>

</PreferenceCategory>

</PreferenceScreen>

</span>

三、在values目录下的string中的代码：

[html] view
plaincopyprint?

<span style="font-size:16px;"><?xml version="1.0" encoding="utf-8"?>

<resources>

<string name="hello">Hello World, SoundSettingMainActivity!</string>

<string name="app_name">SoundSettingApp</string>

<string name="pref_sounds_storage_title">大明原创SoundSetting</string>

<string name="pref_title_notification_ringtone">选择短信铃声</string>

<string name="pref_summary_notification_ringtone">默认短信铃声</string>

<string name="pref_title_phone_ringtone">选择手机铃声</string>

<string name="pref_summary_phone_ringtone">默认手机铃声</string>

<string name="pref_title_alarm_ringtone">选择闹钟铃声</string>

<string name="pref_summary_alarm_ringtone">默认闹钟铃声</string>

<string name="pref_title_sdcard_ringtone">选择Sdcard中的铃声</string>

<string name="pref_summary_sdcard_ringtone">默认Sdcard铃声</string>

<string name="select_ringtone_slient">静音</string>

</resources>

</span>

四、在AndroidManifest.xml中的代码：

[html] view
plaincopyprint?

<span style="font-size:16px;"><?xml version="1.0" encoding="utf-8"?>

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

package="com.cn.android.daming"

android:versionCode="1"

android:versionName="1.0">

<uses-sdk android:minSdkVersion="8" />

<application android:icon="@drawable/icon" android:label="@string/app_name">

<activity android:name=".SoundSettingMainActivity"

android:label="@string/app_name">

<intent-filter>

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

<category android:name="android.intent.category.LAUNCHER" />

</intent-filter>

</activity>

</application>

</manifest></span>
