Android 安卓系统中的popmenu中没有出现图像？

}

//这是主要活动

弹出窗口工作正常，但android:icon=“@drawable/ic_launcher”不工作popmenu中没有出现图像/图标，请告诉我如何在android中设置popmenu中的图标。 我是android新手。

更改行：

public class MainActivity extends Activity {
private Button button1;
@Override
protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);  
          setContentView(R.layout.activity_main);  

          button1 = (Button) findViewById(R.id.button1);  
          button1.setOnClickListener(new OnClickListener() {  

           @Override  
           public void onClick(View v) {  
            //Creating the instance of PopupMenu




            PopupMenu popup = new PopupMenu(MainActivity.this, button1);  
            //Inflating the Popup using xml file  
            popup.getMenuInflater().inflate(R.menu.main, popup.getMenu());  
            //popup.add(0, MENU_QUIT, 0, "Quit").setIcon(R.drawable.menu_quit_icon);

            //registering popup with OnMenuItemClickListener 

            popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {  

             public boolean onMenuItemClick(MenuItem item) { 

              Toast.makeText(MainActivity.this,"You Clicked : " + item.getTitle(),Toast.LENGTH_SHORT).show();  
              return true;  
             }  
            });  

            popup.show();//showing popup menu  
           }  
          });//closing the setOnClickListener method  
         } 


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

设置showAsAction=“ifRoom”。先生，设置showAsAction=“ifRoom”在标题右侧显示图像，不在弹出菜单中请检查此答案-先生，其在标题栏上给出图标，但不在弹出菜单中，我的弹出菜单操作按钮的点击，然后您必须为该弹出菜单创建另一个xml文件，并将其设置在第行上方。先生，我正在/res/menu/main.xml中创建该文件，但它也不工作。我想知道popmenu是否有任何问题，如上下文菜单等//main.xml我要的是显示弹出菜单的代码..不要在这里发布。。请在你的问题中编辑它。
