1、Broadcast接收系統廣播的intent 監控應用程序包的安裝 刪除
public class getBroadcast extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if(Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction())){
Toast.makeText(context, "有應用被添加", Toast.LENGTH_LONG).show();
}
else if(Intent.ACTION_PACKAGE_REMOVED.equals(intent.getAction())){
Toast.makeText(context, "有應用被刪除", Toast.LENGTH_LONG).show();
}
else if(Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())){
Toast.makeText(context, "有應用被替換", Toast.LENGTH_LONG).show();
}
else if(Intent.ACTION_CAMERA_BUTTON.equals(intent.getAction())){
Toast.makeText(context, "按鍵", Toast.LENGTH_LONG).show();
}
}
}
需要聲明的權限如下AndroidManifest.xml
view plaincopy to clipboardprint?
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="zy.Broadcast"
android:versionCode="1"

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name="getBroadcast" android:enabled="true" >
<intent-filter>
<action android:name="android.intent.action.PACKAGE_ADDED"></action>
<!-- <action android:name="android.intent.action.PACKAGE_CHANGED"></action>-->
<action android:name="android.intent.action.PACKAGE_REMOVED"></action>
<action android:name="android.intent.action.PACKAGE_REPLACED"></action>
<!-- <action android:name="android.intent.action.PACKAGE_RESTARTED"></action>-->
<!-- <action android:name="android.intent.action.PACKAGE_INSTALL"></action>-->
<action android:name="android.intent.action.CAMERA_BUTTON"></action>
<data android:scheme="package"></data>
</intent-filter>
</receiver>
</application>
<uses-sdk android:minSdkVersion="3" />
</manifest>
2、調用Android installer 安裝和卸載程序
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File("/sdcard/WorldCupTimer.apk")), "application/vnd.android.package-archive");
startActivity(intent); //安裝 程序
Uri packageURI = Uri.parse("package:zy.dnh");
Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI);
startActivity(uninstallIntent);//正常卸載程序
3、 結束某個進程
activityManager.restartPackage(packageName);
4、 設置默認來電鈴聲
public void setMyRingtone()
{
File k = new File("/sdcard/Shall We Talk.mp3"); // 設置歌曲路徑
ContentValues values = new ContentValues();
values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
values.put(MediaStore.MediaColumns.TITLE, "Shall We Talk");
values.put(MediaStore.MediaColumns.SIZE, 8474325);
values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
values.put(MediaStore.Audio.Media.ARTIST, "Madonna");
values.put(MediaStore.Audio.Media.DURATION, 230);
values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
values.put(MediaStore.Audio.Media.IS_ALARM, false);
values.put(MediaStore.Audio.Media.IS_MUSIC, false);
// Insert it into the database
Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath());
Uri newUri = this.getContentResolver().insert(uri, values);
RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);
;}
需要的權限
<uses-permission android:name="android.permission.WRITE_SETTINGS"></uses-permission>
5、ListView點擊後不讓他高亮的辦法:android:listSelector="@android:color/transparent"
6、android:layout_gravity 佈局位置
android:gravity 內容位置
