设置背景信息:

RelativeLayout layout = (RelativeLayout) findViewById(R.id.background);
layout.setBackgroundResource(R.drawable.ready);

这是最好的方法吗?

试试下面的代码:

Drawable thumb = ContextCompat.getDrawable(getActivity(), R.mipmap.cir_32);
mSeekBar.setThumb(thumb);

试试这个。

 int res = getResources().getIdentifier("you_image", "drawable", "com.my.package");
 preview = (ImageView) findViewById(R.id.preview);
 preview.setBackgroundResource(res);

试试这个:

layout.setBackground(ContextCompat.getDrawable(context, R.drawable.ready));

对于API 16<:

layout.setBackgroundDrawable(ContextCompat.getDrawable(context, R.drawable.ready));
