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。
