试着这么做：

        Drawable icon = packageManager.getApplicationIcon(app);
        String name = packageManager.getApplicationLabel(app);
        return icon;
    } catch (NameNotFoundException e) {
        Toast toast = Toast.makeText(this, "error in getting icon", Toast.LENGTH_SHORT);
        toast.show();
        e.printStackTrace();
