您如何为RemoteViews充气？

问题描述

我正在尝试获取通知的RemoteViews中ImageButton的高度，以便创建一个正方形位图以应用于该高度。问题是当我为inflate()返回的视图充气时，高度为0。我认为这是因为传递给RemoteViews的apply()的父级为null。

是否有用于通知的父级ViewGroup？有没有办法在通知中放大后的ImageButton的高度？

这是我尝试过的：

        // This is where the parent is null. 
        View view = remoteViewNotificationLayout.apply(this,null);
        LayoutInflater layoutInflater = (LayoutInflater) getSystemService( Context.LAYOUT_INFLATER_SERVICE );
        // Not sure what ViewGroup to use
        view = layoutInflater.inflate(R.layout.notification_song_pane,(ViewGroup) view.getRootView());
        ImageView imageView = view.findViewById(R.id.imageButtonNotificationSongPaneNext);
        int height = imageView.getMeasuredHeight();
        //noinspection SuspicIoUsNameCombination
        int width = height;
        Drawable drawable = getResources().getDrawable(R.drawable.skip_next_black_24dp);
        drawable.setBounds(0,width,height);
        // I get an exception here because width and height are 0
        Bitmap bitmap = Bitmap.createBitmap(width,height,Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(bitmap);
        drawable.draw(canvas);
        // Convenience method for creating the square Bitmap
        Bitmap bitmapResized = FragmentSongPane.getResizedBitmap(bitmap,height);
        bitmap.recycle();
        remoteViewNotificationLayout.setBitmap(R.id.imageButtonNotificationSongPaneNext,"setimageBitmap",bitmapResized);
        view = remoteViewNotificationLayout.apply(this,null);
        remoteViewNotificationLayout.reapply(this,view);
        builder.setContent(remoteViewNotificationLayout);
