Question

我目前正在构建一个带有phonegap的移动应用程序由于我在重新启动手机/重新启动应用程序时遇到了一致的HTML5存储问题，我想添加原生Android菜单以关闭应用程序以进行测试，因为通过应用程序管理器强行关闭它真的很烦人。

public class GridTestActivity extends DroidGap {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    super.loadUrl("file:///android_asset/www/TestPage.html");
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);
    MenuInflater inflater = super.getMenuInflater();
    inflater.inflate(R.menu.menu, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    super.onOptionsItemSelected(item);
    Toast.makeText(this, "Menu item pressed", Toast.LENGTH_SHORT).show();
    return true;
}

}

Eclipse中没有警告或错误。

按下菜单按钮时，没有任何事情发生。有什么建议？在此先感谢:)

我不明白为什么你要使用超类。尝试删除super并将两个选项菜单功能放在oncreate功能之上。否则，我根本没有看到您的代码有任何问题。

Phonegap中的原生Android菜单。无法让我的代码工作
