如何在Android應用程序的ANDROID

Question

下面的條件下停止正在運行的線程，當用戶單擊某個拼寫按鈕時，它會播放音頻以顯示每個字母來讀出一個單詞的字母。它成功實施！

而我用滑動手勢來改變這個詞。如果用戶滑動屏幕，則應該顯示另一個單詞。並且它也成功實施了！

問題：
而如果用戶刷那麼音頻應停止並應和顯示下一個單詞（我猜正在運行的線程應該停止）音頻播放。

我該怎麼做？任何方案？

代碼概述：

public class BirdsActivity extends Activity implements OnClickListener{ 

//On createMethod*(){ 
. 
. 
    //on Spell button click run a thread to play audio and draw text 
    new DrawLetter("AlphaKids").start(); 

// initiate Gesture detection 

    } 


class DrawLetter extends Thread { 
    String tempName=names[position];  
    String b=""; 
    int i=0; 
    public DrawLetter(String str) { 
    super(str); 
    } 
    public void run() { 

     for (int i = 0; i < names[position].length(); i++) { 
    runOnUiThread(new Runnable() 
       {    
        public void run() 
        {  txtFrontName.setText(b); } 

       }); 

      mPlayVoice = MediaPlayer.create(BirdsActivity.this, mAlphabetsSound[letterPosition]); 
       mPlayVoice.start(); 
       try { 
      sleep(500); 
      mPlayVoice.release(); 
      } catch (InterruptedException e) {} 
    }} 
. 
. 
. 
    // Gesture detection class 

@Override 
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { 

     //if valid swipe is performed 
     { 
      //i want to stop(or Distroy) the above thread here 

    } 
} } 

Answer 1

我想你沒有破壞線程你的自我。停止音樂mPlayVoice.stop（）;因爲這個變量是在UIThread中聲明的...它可以在UIThread中訪問，你可以從那裏停止你的播放器。最有可能在處理程序。

Answer 2

mPlayVoice.stop()

boolean shouldPlayVoice = true; 
... 
if(shouldPlayVoice){ 
mPlayVoice.start(); 
} 
... 
mPlayVoice.stop(); 
shouldPlayVoice = false;
