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>
