android - 使用 setCompoundDrawablesWithIntrinsicBounds() 时如何设置图像大小？

Question

我需要在选项卡布局中的选项卡中将图像设置在文本上方。所以我使用 setCompoundDrawablesWithIntrinsicBounds 在我的 TextView 中设置图像，但我不知道如何为我的图像指定大小。

我试着给出这样的尺寸:

Drawable dr = ContextCompat.getDrawable(MainActivity.this, R.drawable.mobile_icon);
    Bitmap bitmap = ((BitmapDrawable) dr).getBitmap();
    mobile_drawable = new BitmapDrawable(getResources(), Bitmap.createScaledBitmap(bitmap, 50, 50, true));

    TextView tabOne = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
    tabOne.setText("Mobile");
    tabOne.setCompoundDrawablesWithIntrinsicBounds(0,mobile_drawable,0,0);
    tabLayout.getTabAt(0).setCustomView(tabOne);

但它给了我这个错误:

Cannot resolve method setCompoundDrawablesWithIntrinsicBounds(int,android.graphics.drawable.Drawable,int,int);

我也试过

tabOne.setCompoundDrawables(0,mobile_drawable,0,0);

但它也不起作用？

那么在使用setCompoundDrawablesWithIntrinsicBounds时如何给图片大小呢？？？

检查一下

Drawable img = ContextCompat.getDrawable(MainActivity.this,R.drawable.btn_img);
// You need to setBounds before setCompoundDrawables , or it couldn't display
img.setBounds(0, 0, img.getMinimumWidth(), img.getMinimumHeight());
btn.setCompoundDrawables(img, null, null, null); 

Calculate image size when using setCompoundDrawables for EditText
