handler.sendMessage(handler.obtainMessage());
}
mp.reset();
mp.prepare();
mp2 = MediaPlayer.create(getApplicationContext(), R.raw.AudioFile2);
mp2.setLooping(true);
mp2.start();
}catch(Exception ex){
ex.printStackTrace();

}
// our handler
Handler handler = new Handler() {
public void handleMessage(Message msg) {//display each item in a single line
{
Random rgenerator = new Random();
Resources res = getResources();
myString = res.getStringArray(R.array.myArray);
String q = myString[rgenerator.nextInt(myString.length)];
txt.setText(q);
}
}
};
}

Add the line:
添加行：
mp.setLooping(true);
Then set false when you want to stop it looping.
然后在您想停止循环时设置 false。

Your code has several errors. Typos, cases,
您的代码有几个错误。错别字，案例，
ex.: Medaiplayer should be MediaPlayer
例如：媒体播放器应该是媒体播放器
This alone would be enough to cause the error. Also, declaring your variables outside the method is a good idea.
仅此一项就足以导致错误。此外，在方法之外声明变量是一个好主意。
