android - 菜单项不可见

Question

我正在做菜单项。但我无法在屏幕上查看菜单项。查看菜单项需要做什么。我的代码：

            public boolean onCreateOptionMenu(Menu menu){
      super.onCreateOptionsMenu(menu);

       int group1 = 1;
       int group2 = 2;

      MenuItem info = menu.add(group1,1,1,"About");
      info.setIcon(R.drawable.ic_launcher);
      MenuItem set = menu.add(group2,2,2,"App Setting");
      set.setIcon(R.drawable.images);

       return true;
      }


         private boolean MenuChoice(MenuItem item){

            switch(item.getItemId()){
                case 1:
                Toast.makeText(this, "You clicked on item 1",    Toast.LENGTH_LONG).show();
                return true;
        }

       return false;
    }

我也有这个问题......在我的情况下，这是因为图像保存在文件夹“ drawable”中。我把它们移到了“ drawable-hdpi”那一个，问题就解决了！干杯。

用这个：

public boolean onCreateOptionsMenu(Menu menu){
    Log.d(TAG, "CreateMenu");

     MenuInflater inflater = getMenuInflater();
     inflater.inflate(R.layout.menu, menu);
       return true;


}



@Override
public boolean onOptionsItemSelected(MenuItem item)
{    

        switch(item.getItemId()) {
                    case R.id.x:

            Toast.makeText(this, "You clicked on item 1",    Toast.LENGTH_LONG)         }
                        break;
                    }


    }
    return true;
}

缺少菜单充气机：

MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.game_menu, menu);

Android Developers上有一个关于Menus的很好的参考资料。

super.onCreateOptionsMenu(menu)从回来后试试onCreateOptionMenu

 public boolean onCreateOptionMenu(Menu menu){

   int group1 = 1;
   int group2 = 2;

   menu.add(group1,1,1,"About").setIcon(R.drawable.ic_launcher);
   menu.add(group2,2,2,"App Setting").setIcon(R.drawable.images);

   return super.onCreateOptionsMenu(menu);;
}

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

我的原因是在styles.xml 中，父母的主题有误。确保它以 android 开头：试试这个：

<!-- Base application theme. -->
<style name="AppTheme" parent="android:Theme.DeviceDefault.Light.DarkActionBar">
    <!-- Customize your theme here. -->
</style>
