如何创建带有选项图标的Android汉堡按钮？

Question

在android中创建一个带有多个自定义选项的汉堡按钮。当我单击该按钮时，我希望它显示带有相应图标的选项(如下图所示)。

​

​

我使用了弹出菜单，但是如何在弹出菜单选项中设置图标？

请帮帮我？？

Answer 1

您可以尝试使用ListPopUpWindow并将其锚定到汉堡按钮(如果您没有使用actionbar)

http://developer.android.com/reference/android/widget/ListPopupWindow.html

String [] items = new String[]{"Item1" , "Item2", "Item3"};

View anchor= (Button)findViewById(R.id.BurgerButton);

 anchor.setOnClickListener(new OnClickListener(){

     showpopup();

});


public void showpopup()
{


ListPopupWindow popup = new ListPopupWindow(this);
//Replace this  adapter with a custom adapter and layout for a custom menu item
popup.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1,items));
popup.setAnchorView(anchor);
popup.setWidth(200);
popup.show();

}

Answer 2

试试这个: popup_menu

    <menu xmlns:androclass="http://schemas.android.com/apk/res/android" >  

        <item  
            android:id="@+id/one"  
            android:title="One"
            android:icon="@drawable:ic_launcher"/>  

        <item  
            android:id="@+id/two"  
            android:title="Two"/>  

        <item  
            android:id="@+id/three"  
            android:title="Three"/>  

    </menu>  

在activity on按钮中，单击add this：

 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.popup_menu, popup.getMenu());  

            //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  

希望它能有所帮助:)

对于菜单图标，显示添加：

// Force icons to show
                Object menuHelper;
                Class[] argTypes;
                try {
                    Field fMenuHelper = PopupMenu.class.getDeclaredField("mPopup");
                    fMenuHelper.setAccessible(true);
                    menuHelper = fMenuHelper.get(popup);
                    argTypes = new Class[] { boolean.class };
                    menuHelper.getClass().getDeclaredMethod("setForceShowIcon", argTypes).invoke(menuHelper, true);
                } catch (Exception e) {
                    // Possible exceptions are NoSuchMethodError and NoSuchFieldError
                    //
                    // In either case, an exception indicates something is wrong with the reflection code, or the
                    // structure of the PopupMenu class or its dependencies has changed.
                    //
                    // These exceptions should never happen since we're shipping the AppCompat library in our own apk,
                    // but in the case that they do, we simply can't force icons to display, so log the error and
                    // show the menu normally.

                    Log.w("error", "error forcing menu icons to show", e);
                    popup.show();
                    return;
                }
