Android中铃声总结【安卓源码解析一】

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:
<?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>
三、在values目录下的string中的代码:
<?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>
四、在AndroidManifest.xml中的代码:
<?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>
