在我调用setCompoundDrawables方法后,复合Drawable没有显示。

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

任何想法吗?

示例设置在顶部:

view.setCompoundDrawablesWithIntrinsicBounds(
    null,
    getResources().getDrawable(R.drawable.some_img),
    null,
    null
);

参数顺序:(左,上,右,下)

其他回答

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中使用Databinding

binding.tvTime.setCompoundDrawablesWithIntrinsicBounds(
            ResourcesCompat.getDrawable(resources, android.R.drawable.ic_menu_recent_history, null),
            null,null,null)

哪里tvTime是textView和位置(右,上,左,下),更多关于绑定在这里 https://stackoverflow.com/a/72360048/12272687

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。

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 );

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)
