  • [Android Pro] 创建快捷方式,删除快捷方式,查询是否存在快捷方式

    1: 创建快捷方式

    需要权限: <uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" /> 

    private static void createShortcut(Context cxt, String shortcutName, int shortcutIconRes,
                String className, boolean duplicate, boolean laucherCategory) {
    
            Intent intent = getShortCutIntent(cxt, cxt.getPackageName(), className, shortcutName,
                    laucherCategory);
            int iconsize = cxt.getResources().getDimensionPixelSize(Res.dimen.app_icon_size);
            BitmapDrawable icon = (BitmapDrawable) cxt.getResources().getDrawable(shortcutIconRes);
            Bitmap bmp = ImageUtils.scaleTo(icon.getBitmap(), iconsize, iconsize, false);
            intent.putExtra(Intent.EXTRA_SHORTCUT_ICON, bmp);
            intent.putExtra(EXTRA_SHORTCUT_DUPLICATE, duplicate);
    
            // Now, notify the launcher to create the shortcut
            cxt.sendBroadcast(intent);
        }
    private static Intent getShortCutIntent(Context cxt, String pkgName, String className,
                String shortcutName, boolean laucherCategory) {
            // Prepare the intents for shortcut
            Intent shortcutIntent = new Intent(Intent.ACTION_VIEW);
            shortcutIntent.setClassName(pkgName, className);
            shortcutIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            shortcutIntent.putExtra(Constants.EXTRA_FROM_KEY, Constants.EXTRA_FROM_VALUE_SHORTCUT);
            if (laucherCategory) {
                shortcutIntent.addCategory(Intent.CATEGORY_LAUNCHER);
                shortcutIntent.setAction(Intent.ACTION_MAIN);
            }
    
            Intent intent = new Intent(ACTION_INSTALL_SHORTCUT);
            intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
            intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, shortcutName);
            return intent;
        }

    2:删除快捷方式(MIUI系统不支持):

    需要权限:<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />

    public static void removeShortcut(Context cxt, String shortcutName, String className,
                boolean removeAll) {
            // Prepare the intents for shortcut
            Intent shortcutIntent = new Intent(Intent.ACTION_VIEW);
            shortcutIntent.setClassName(cxt, className);
    
            Intent intent = new Intent(ACTION_UNINSTALL_SHORTCUT);
            intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
            intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, shortcutName);
            intent.putExtra(EXTRA_SHORTCUT_DUPLICATE, removeAll);
    
            // Now, notify the launcher to remove the shortcut
            cxt.sendBroadcast(intent);
        }

    3:查询快捷方式是否存在(三方rom大部分查询失败,cursor为null)

    需要权限:<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />

      或者      <uses-permission android:name="com.android.launcher.permission.WRITE_SETTINGS" />

    private boolean hasShortcut()
    {
            boolean isInstallShortcut = false;
            final ContentResolver cr = activity.getContentResolver();
            final String AUTHORITY ="com.android.launcher.settings";
            final Uri CONTENT_URI = Uri.parse("content://" +AUTHORITY + "/favorites?notify=true");
            Cursor c = cr.query(CONTENT_URI,new String[] {"title","iconResource" },"title=?",
            new String[] {getString(R.string.app_name).trim()}, null);
            if(c!=null && c.getCount()>0){
    //String title = c.getString(c.getColumnIndexOrThrow("title")); isInstallShortcut
    = true ; } return isInstallShortcut ; }
