Question

package com.Randomsentence; 
    import java.util.Random; 
    import android.app.Activity; 
    import android.content.res.Resources; 
    import android.os.Bundle; 
    import android.os.Handler; 
    import android.os.Message; 
    import android.util.Log; 
    import android.view.View; 
    import android.widget.Button; 
    import android.widget.TextView; 

    public class Randomsentence extends Activity { 
     boolean showRandom = false; 
     TextView txt; 
     int time = 30; 
     int random; 
     public String[] myString; 
     Button bt1; 
     boolean check = false; 

     @Override 
     public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 
     txt=(TextView)findViewById(R.id.txt); 
     bt1 = (Button)findViewById(R.id.bt1); 
     Medaiplayer mp = new Medaiplayer(); 
     Mediaplayer mp2 = new Mediaplayer(); 
     bt1.setOnClickListener(new View.OnClickListener() { 

      @Override 
     public void onClick(View v) { 
     // TODO Auto-generated method stub 
     showRandom = !showRandom; 
       t = new Thread() { 
        public void run() { 
         try { 
          while(showRandom){ 
     mp = MediaPlayer.create(getApplicationContext(), R.raw.AudioFile1); 
     mp.setLooping(true); 
     mp.start(); 
       mp2.reset(); 
       mp2.prepare(); 
       sleep(1000); 
       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(); 
       } 
        } 
       }; 
       t.start(); 

       } 

     }); 

    } 

     // 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); 

      } 
     } 
     }; 
    } 

Answer 1

添加一行：

mp.setLooping(true); 

然后，当你想停止循环设置为false。

Answer 2

您的代码有几个错误。错别字，案件，

例：Medaiplayer应该是MediaPlayer的

仅此一点就足以导致错误。另外，在方法外声明你的变量是个好主意。
