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

我需要在标签布局的标签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提供大小。

我试图给出这样的尺寸:

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时如何给出图像大小???

查看

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

接受的答案是过时的和错误的......

您无法使用setCompoundDrawablesWithIntrinsicBounds

设置可绘制的尺寸

相反,您需要使用setCompoundDrawables这样设置

Drawable img = ContextCompat.getDrawable(yourContext, R.drawable.yourImgId);
img.setBounds(0, 0, yourSize, yourSize);
yourTextView.setCompoundDrawables(img, null, null, null);

答案 2 :(得分:0)

在VS.Xamarin中对我有用的是

text = parentView.FindViewById<EditText>(Resource.Id.text);
Drawable img = ContextCompat.getDrawable(context, R.id.resource_id);
img.SetBounds(0, 0, 20, 20); 
text.SetCompoundDrawables(img, null, null, null);
