Repeate每个按钮被按下

Question

时间声音我编程测验有一个问题，3个选择，一个正确的答案。当我按下3按钮（选择）的右边时，它播放的声音很好，但是当我再次点击时没有任何反应。我希望每次单击右键时声音都会自我重复。我有一个名为选择的列表。在那里，我有一个IF查询，每次按下正确的选择时，它应该重复声音。我想inser部分的代码是if（choice.getText（）。等于（mAnswer））

感谢您寻找下。 :)

Answer 1

因此，尝试做到这一点：

mp.setOnCompletionListener(new OnCompletionListener() { 

     @Override 
     public void onCompletion(MediaPlayer mp) { 
      mp.stop(); 

     } 

     }); 

choice.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       if (choice.getText().equals(mAnswer)) { 
        mp.prepare(); 
        mp.start(); 


        updateScore(); 
        updateQuestion(); 
        Toast.makeText(QuizActivity.this, "Correct", Toast.LENGTH_SHORT).show(); 



       } else { 
        Toast.makeText(QuizActivity.this, "Wrong... Try again!", Toast.LENGTH_SHORT).show(); 

        Intent intent = new Intent(QuizActivity.this, Menu2.class); 
        intent.putExtra("score", mScore); // pass score to Menu2 
        startActivity(intent); 
       } 
      } 
     }); 

其他方式：

choice.setOnClickListener(new View.OnClickListener() { 
       @Override 
       public void onClick(View view) { 
        if (choice.getText().equals(mAnswer)) { 
         try { 
      mp.reset(); 
      AssetFileDescriptor afd; 
      afd = getAssets().openFd("your_sound.mp3"); 
      mp.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength()); 
      mp.prepare(); 
      mp.start(); 
     } catch (IllegalStateException e) { 
      e.printStackTrace(); 
     } catch (IOException e) { 
      e.printStackTrace(); 
     } 
         updateScore(); 
         updateQuestion(); 
         Toast.makeText(QuizActivity.this, "Correct", Toast.LENGTH_SHORT).show(); 



        } else { 
         Toast.makeText(QuizActivity.this, "Wrong... Try again!", Toast.LENGTH_SHORT).show(); 

         Intent intent = new Intent(QuizActivity.this, Menu2.class); 
         intent.putExtra("score", mScore); // pass score to Menu2 
         startActivity(intent); 
        } 
       } 
      }); 

说明：

Acordingŧ这android developers link你需要按照图。 所以，你需要prepare()，start()，stop()重放声音。因为您没有prepare()而且没有stop()媒体播放器没有准备好重播。
