在我调用setCompoundDrawables
方法后,未显示复合Drawable ..
Drawable myDrawable = getResources().getDrawable(R.drawable.btn);
btn.setCompoundDrawables(myDrawable, null, null, null);
有什么想法吗?
使用此(我测试过)。它运作良好
Drawable image = context.getResources().getDrawable( R.drawable.ic_action );
int h = image.getIntrinsicHeight();
int w = image.getIntrinsicWidth();
image.setBounds( 0, 0, w, h );
button.setCompoundDrawables( image, null, null, null );
图像为空白,因为它没有指定的边界。您可以使用setCompoundDrawables()
但在使用Drawable.setBounds()
方法指定图像边界之前
示例设置为顶部:
view.setCompoundDrawablesWithIntrinsicBounds(
null,
getResources().getDrawable(R.drawable.some_img),
null,
null
);
参数顺序:(左,上,右,下)
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 );
它在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);
在Kotlin:
1)设置drawable
:
val drawable = ContextCompat.getDrawable(context!!,R.drawable.ic_image)?.apply {
setBounds(0, 0, intrinsicWidth, intrinsicHeight)
}
要么
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)
要么
button.setCompoundDrawables(null, drawable, null, null)
Kotlin的例子:
val myView = layoutInflater.inflate(R.layout.my_view, null) as TextView
myView.setCompoundDrawablesWithIntrinsicBounds(0, myDrawable, 0, 0)
