首先，对不起我的英语水平。

我需要一些帮助。我正在尝试开发一个应用程序（您单击按钮并听到声音的音箱）。我没有问题，但是在听了一些歌曲之后，我有记忆问题。这是我的日志：

我该如何解决？我已经放了两个标签，但歌曲只在第一个标签上。这是代码java：

public class MainActivity extends TabActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Gestion des onglets

        // Tout d'abord on récupère les ressources qui seront utilisés plus tard :
        Resources res = getResources();
        // On prépare les éléments nécessaires pour chaque onglet :
        TabHost tabHost = getTabHost();
        TabHost.TabSpec spec;
        Intent intent;



        // on lie nos onglets à la principale activity :
        // ONGLET 1        
        intent = new Intent().setClass(this, Tab1.class);
        spec = tabHost.newTabSpec("Widget").setIndicator("Cinema", res.getDrawable(R.drawable.movies)).setContent(intent);
        tabHost.addTab(spec);

        // ONGLET 2
        intent = new Intent().setClass(this, Tab2.class);
        spec = tabHost.newTabSpec("Form").setIndicator("Infos", res.getDrawable(R.drawable.infos)).setContent(intent);
        tabHost.addTab(spec);

        // On choisit l'onglet par défaut
        tabHost.setCurrentTab(0);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.layout.activity_main, menu);
        return true;
    }
}



public class Tab1 extends Activity {

private MediaPlayer mPlayer = null;


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.onglet1);

    generateSoundOnButton(sound64, R.id.btn64);  
   */
}


    public void generateSoundOnButton(final int soundId, int idButton) {

        final ImageButton btn = (ImageButton) findViewById(idButton);

        btn.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {       
                playSound(soundId);                 
            }

          });
    }


    @Override
    public void onPause() {
        super.onPause();
        if(mPlayer != null) {
            mPlayer.stop();
            mPlayer.release();          
        }
    }

    private void playSound(int resId) {     

        if(mPlayer != null) {
            mPlayer.stop();
            mPlayer.release();
        }
        mPlayer = MediaPlayer.create(this, resId);
        mPlayer.start();
    }

}



public class Tab2 extends Activity {


    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.onglet2);          
    }       
}

实际上一开始我删除了方法 mPlayer.stop() 因为有错误并且没有这个方法它工作得很好，所以我认为现在是问题但是当我再次添加这个方法时没有发生任何事情，有同样的错误. 真的有一个好方法可以在android上正确播放声音而不会出现问题吗？

任何帮助和建议将不胜感激。如果您有任何意见或问题，请不要犹豫。

非常感谢您的帮助。

是的，但它已经很喜欢了。我在 res/menu 中有一个带有以下代码的 activity_main.xml：

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_settings"
        android:title="@string/menu_settings"
        android:orderInCategory="100" />
</menu>

我在 res/layout 中有三个文件：activity_main.xml，代码如下：

<?xml version="1.0" encoding="utf-8"?>

<!-- MISE EN PLACE DE LA BASE DE NOS 3 ONGLETS -->
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:background="#66FF99">
    <LinearLayout  
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp"
        android:background="#E2F0FF">

        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:background="#FFFFFF"
             />

        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:padding="5dp"
            android:background="#E2F0FF" />
    </LinearLayout>
</TabHost>

onglet1.xml 与所有歌曲的 tab1 相等（我认为没有其他解决方案可以编写所有 xml 代码......？）：

<?xml version="1.0" encoding="utf-8"?>
