在芬兰湾的科特林:

1)设置可绘制:

val drawable = ContextCompat.getDrawable(context!!,R.drawable.ic_image)?.apply {
    setBounds(0, 0, intrinsicWidth, intrinsicHeight)
}

or

val drawable = ResourcesCompat.getDrawable(resources, R.drawable.ic_image, null)?.apply {
    setBounds(0, 0, minimumWidth, minimumHeight)
}

2)设置TextView:

textView.setCompoundDrawablesWithIntrinsicBounds(drawable, null, null, null)

or

button.setCompoundDrawables(null, drawable, null, null)

button.setCompoundDrawables(null, drawable, null, null)

我需要使用setCompoundDrawablesWithIntrinsicBounds。

再简单一点:

Drawable image = context.getResources().getDrawable(R.drawable.ic_action );
image.setBounds( 0, 0, image.getIntrinsicWidth(), image.getIntrinsicHeight() );
button.setCompoundDrawables( image, null, null, null );

图像没有显示，因为你没有指定边界，所以你有两个选项。

1号方法

使用setcompounddrawableswithintrinsic icbounds方法，如下所示

Drawable myDrawable = getResources().getDrawable(R.drawable.btn);
btn. setCompoundDrawablesWithIntrinsicBounds(myDrawable, null, null, null);

2方法

你可以在应用到TextView之前对可绘制对象应用边界，如下所示

Drawable myDrawable = getResources().getDrawable(R.drawable.btn);
myDrawable.setBounds( 0, 0, myDrawable.getIntrinsicWidth(), myDrawable.getIntrinsicHeight());
btn.setCompoundDrawables(myDrawable, null, null, null);

就是这样。

在API 22中已弃用。

这段代码对我很有用:

Drawable drawable = ResourcesCompat.getDrawable(getResources(),R.drawable.wen, null);
drawable.setBounds(0, 0, drawable.getMinimumWidth(),
drawable.getMinimumHeight());
tv.setCompoundDrawables(drawable, null, null, null);
