Android中铃声总结【安卓源码解析一】

 
阅读更多
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！

下面请看截图：

第一次打开程序的界面：点击“选择短信铃声”后的界面：

选择铃声的dialog后的界面： 点击“选择手机铃声”后的界面：

点击“选择手机铃声”后的界面：点击“选择闹钟铃声”后的dialog界面：

点击“选择sdcard中的铃声”后的界面： 点击“选择曲目”后弹出sdcard的界面：

下面代码附上：

在SoundSettingActivity这个工程下面：

一、在com.cn.android.daming包的SoundSettingMainActivity.java类中的代码：

  285. }
  286. default:break;
  287. }
  288. }
  289. }</span>

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

view plainprint?
  1. <spanstyle="font-size:16px;"><?xmlversion="1.0"encoding="utf-8"?>
  2. <PreferenceScreen
  3. xmlns:android="http://schemas.android.com/apk/res/android">
  4. <PreferenceCategoryandroid:title="@string/pref_sounds_storage_title"
  5. android:key="pref_key_storage_settings">
  6. <Preference
  7. android:layout="?android:attr/preferenceLayoutChild"
  8. android:key="pref_sms_ringtone"
  9. android:ringtoneType="notification"
  10. android:title="@string/pref_title_notification_ringtone"
  11. android:summary="@string/pref_summary_notification_ringtone"
  12. />
  13. <Preference
  14. android:layout="?android:attr/preferenceLayoutChild"
  15. android:key="pref_phone_ringtone"
  16. android:ringtoneType="notification"
  17. android:title="@string/pref_title_phone_ringtone"
  18. android:summary="@string/pref_summary_phone_ringtone"
  19. />
  20. <Preference
  21. android:layout="?android:attr/preferenceLayoutChild"
  22. android:key="pref_alarm_ringtone"
  23. android:ringtoneType="notification"
  24. android:title="@string/pref_title_alarm_ringtone"
  25. android:summary="@string/pref_summary_alarm_ringtone"
  26. />
  27. <Preference
  28. android:layout="?android:attr/preferenceLayoutChild"
  29. android:key="pref_sdcard_ringtone"
  30. android:ringtoneType="notification"
  31. android:title="@string/pref_title_sdcard_ringtone"
  32. android:summary="@string/pref_summary_sdcard_ringtone"
  33. />
  34. </PreferenceCategory>
  35. </PreferenceScreen>
  36. </span>

三、在values目录下的string中的代码：

view plainprint?
  1. <spanstyle="font-size:16px;"><?xmlversion="1.0"encoding="utf-8"?>
  2. <resources>
  3. <stringname="hello">HelloWorld,SoundSettingMainActivity!</string>
  4. <stringname="app_name">SoundSettingApp</string>
  5. <stringname="pref_sounds_storage_title">大明原创SoundSetting</string>
  6. <stringname="pref_title_notification_ringtone">选择短信铃声</string>
  7. <stringname="pref_summary_notification_ringtone">默认短信铃声</string>
  8. <stringname="pref_title_phone_ringtone">选择手机铃声</string>
  9. <stringname="pref_summary_phone_ringtone">默认手机铃声</string>
  10. <stringname="pref_title_alarm_ringtone">选择闹钟铃声</string>
  11. <stringname="pref_summary_alarm_ringtone">默认闹钟铃声</string>
  12. <stringname="pref_title_sdcard_ringtone">选择Sdcard中的铃声</string>
  13. <stringname="pref_summary_sdcard_ringtone">默认Sdcard铃声</string>
  14. <stringname="select_ringtone_slient">静音</string>
  15. </resources>
  16. </span>


四、在AndroidManifest.xml中的代码：

view plainprint?
  1. <spanstyle="font-size:16px;"><?xmlversion="1.0"encoding="utf-8"?>
  2. <manifestxmlns:android="http://schemas.android.com/apk/res/android"
  3. package="com.cn.android.daming"
  4. android:versionCode="1"
  5. android:versionName="1.0">
  6. <uses-sdkandroid:minSdkVersion="8"/>
  8. <applicationandroid:icon="@drawable/icon"android:label="@string/app_name">
  9. <activityandroid:name=".SoundSettingMainActivity"
  10. android:label="@string/app_name">
  11. <intent-filter>
  12. <actionandroid:name="android.intent.action.MAIN"/>
  13. <categoryandroid:name="android.intent.category.LAUNCHER"/>
  14. </intent-filter>
  15. </activity>
  16. </application>完整代码下载地址：http://download.csdn.net/detail/wdaming1986/3736718
