Android桌面快捷方式的设置(二)

MainActivity如下:

package cn.testshortcut;import android.net.Uri;import android.os.Build;import android.os.Bundle;import android.app.Activity;import android.content.ContentResolver;import android.content.Context;import android.content.Intent;import android.content.pm.PackageManager;import android.content.pm.PackageManager.NameNotFoundException;import android.database.Cursor;/** * Demo描述: * 桌面快捷方式的设置 *  * 备注说明: * 该方式只适合Android原生系统 *  * 权限设置: * <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" /> * <uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" /> */public class MainActivity extends Activity {@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);addShortcutToDesktop(MainActivity.this);}public static void addShortcutToDesktop(Context context) {if (!isShortcutExist(context)) {Intent shortcutIntent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");shortcutIntent.putExtra("duplicate", false);shortcutIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME,context.getString(R.string.app_name));shortcutIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,Intent.ShortcutIconResource.fromContext(context,R.drawable.ic_launcher));Intent intent = new Intent(context, MainActivity.class);intent.setAction("android.intent.action.MAIN");intent.addCategory("android.intent.category.LAUNCHER");shortcutIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, intent);context.sendBroadcast(shortcutIntent);}}public static boolean isShortcutExist(Context context) {ContentResolver contentResolver = context.getContentResolver();String AUTHORITY = null;if (Build.VERSION.SDK_INT >= 8) {AUTHORITY = "com.android.launcher2.settings";} else {AUTHORITY = "com.android.launcher.settings";}String title = "";PackageManager packageManager = context.getPackageManager();try {title = packageManager.getApplicationLabel(packageManager.getApplicationInfo(context.getPackageName(), PackageManager.GET_META_DATA)).toString();} catch (NameNotFoundException e) {e.printStackTrace();}Uri uri = Uri.parse("content://" + AUTHORITY + "/favorites?notify=true");Cursor cursor = contentResolver.query(uri, null,"title=?", new String[] { title },null);if (cursor != null && cursor.getCount() > 0) {return true;}return false;}}

 

main.xml如下:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"     >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="建立桌面快捷方式"        android:layout_centerInParent="true"     /></RelativeLayout>
