Android：如何通過編程將TextView設置為ImageView的頂部

Question

我已經通過動態創建了ImageView，我想通過編程將一個TextView設置到ImageView的頂部。

這是我的代碼。

    windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
    Bitmap bm = BitmapFactory.decodeResource(getResources(),
              R.drawable.ic_launcher);
    chatHead = new ImageView(this);
    num = new TextView(this);

    chatHead.setImageBitmap(getCircleBitmap(bm, 200));
    final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.TYPE_PHONE,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);

    params.gravity = Gravity.TOP | Gravity.LEFT;
    params.x = 0;
    params.y = 100;
windowManager.addView(chatHead, params);

Answer 1

也為textview使用相同的參數：

windowManager.addView(num, params);

它將在圖像上顯示textview。
