Android添加(创建)、删除及判断是否存在桌面快捷方式的方法

本文实例讲述了Android添加(创建)、删除及判断是否存在桌面快捷方式的方法。分享给大家供大家参考。具体实现方法如下：

/*** 判断桌面是否已添加快捷方式* * @param cx* @param titleName* 快捷方式名称* @return*/public static boolean hasShortcut(Context cx) {boolean result = false;// 获取当前应用名称String title = null;try {final PackageManager pm = cx.getPackageManager();title = pm.getApplicationLabel(pm.getApplicationInfo(cx.getPackageName(),PackageManager.GET_META_DATA)).toString();} catch (Exception e) {}final String uriStr;if (android.os.Build.VERSION.SDK_INT < 8) {uriStr = "content://com.android.launcher.settings/favorites?notify=true";} else {uriStr = "content://com.android.launcher2.settings/favorites?notify=true";}final Uri CONTENT_URI = Uri.parse(uriStr);final Cursor c = cx.getContentResolver().query(CONTENT_URI, null,"title=?", new String[] { title }, null);if (c != null && c.getCount() > 0) {result = true;}return result;}/*** 删除当前应用的桌面快捷方式* * @param cx*/public static void delShortcut(Context cx) {Intent shortcut = new Intent("com.android.launcher.action.UNINSTALL_SHORTCUT");// 获取当前应用名称String title = null;try {final PackageManager pm = cx.getPackageManager();title = pm.getApplicationLabel(pm.getApplicationInfo(cx.getPackageName(),PackageManager.GET_META_DATA)).toString();Log.v("test", "title:" + title);} catch (Exception e) {}// 快捷方式名称shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, title);Intent shortcutIntent = cx.getPackageManager().getLaunchIntentForPackage(cx.getPackageName());shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);cx.sendBroadcast(shortcut);}/*** 为当前应用添加桌面快捷方式* * @param cx* @param appName* 快捷方式名称*/public static void addShortcut(Context cx) {Intent shortcut = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");Intent shortcutIntent = cx.getPackageManager().getLaunchIntentForPackage(cx.getPackageName());shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);// 获取当前应用名称String title = null;try {final PackageManager pm = cx.getPackageManager();title = pm.getApplicationLabel(pm.getApplicationInfo(cx.getPackageName(),PackageManager.GET_META_DATA)).toString();Log.v("test", "title:" + title);} catch (Exception e) {}// 快捷方式名称shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, title);// 不允许重复创建（不一定有效）shortcut.putExtra("duplicate", false);// 快捷方式的图标Parcelable iconResource = Intent.ShortcutIconResource.fromContext(cx, R.drawable.icon);shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);cx.sendBroadcast(shortcut);}

希望本文所述对大家的Android程序设计有所帮助。
