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（你点击按钮的声音盒，你会听到声音）。我没有问题但是在听了一些歌后，我有一个记忆问题。这是我的日志：

我该如何解决？我已经放了两个标签，但歌曲只是在第一个。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

    super.onCreate(savedInstanceState);

   */
}


    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);          
    }       
}

实际上在开始时我删除了方法mPlayer.stop（）因为有bug而且没有这个方法它运行得很好，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。有没有一个很好的方法来正确播放声音而没有安卓问题？

任何帮助和建议都会非常感激。如果您有任何意见或问题，请不要犹豫。

非常感谢你的帮助。

是的，但已经很喜欢了。我在res / menu中有一个activity_main.xml，代码如下：

<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>

并且onglet1.xml等于tab1与所有歌曲（我认为没有其他解决方案来编写所有xml代码......？）：

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

    android:id="@+id/linearLayoutOnglet1"
