Answer 1

Timer timer = new Timer();
TimerTask timerTask  = new TimerTask() {
@Override
public void run() {
// TODO Auto-generated method stub
if(loadFirst){
loadFirst = false;
layout_reference.setBackgroundResource(R.drawable.imagename1);
}else{
loadFirst = true;
layout_reference.setBackgroundResource(R.drawable.imagename2);
}
}
};
timer.schedule(timerTask,0,10000);//fires every 10secs 

在代码中尝试这段代码，并在你的 oncreate 方法()中声明一个 bool 变量“boolean loadFirst = false”
