单击按钮切换 TextView 背景

Switching TextView backgorund on button click

有没有办法在我按下按钮时切换 TextView 背景?

背景在drawable文件夹中,我需要这样的东西:

public void ChangeBG(){
    Button mybutton = (Button) findViewById(R.id.button1);
    mybutton.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {

            //SET  R.DRAWABLE.BG2  AS BACKGROUND

        }
    });
}

我觉得很简单

 textView.setBackgroundResource(R.drawable.your_image);
