是否可以自定义Android PopupMenu？

Question

是否可以自定义PopupMenu布局？我只需要圆角，是否可以使用库存定制？

Answer 1

对于自定义布局不使用PopupMenu的，替代的选择是PopupWindow

PopupWindow popupwindow_obj = popupDisplay(); 
    popupwindow_obj.showAsDropDown(clickbtn, -40, 18); // where u want show on view click event popupwindow.showAsDropDown(view, x, y); 

public PopupWindow popupDisplay() { 

    final PopupWindow popupWindow = new PopupWindow(this); 

    // inflate your layout or dynamically add view 
    LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    View view = inflater.inflate(R.layout.my_popupwindow_layout, null); 


    popupWindow.setFocusable(true); 
    popupWindow.setWidth(WindowManager.LayoutParams.WRAP_CONTENT); 
    popupWindow.setHeight(WindowManager.LayoutParams.WRAP_CONTENT); 
    popupWindow.setContentView(view); 

    return popupWindow; 
} 

创建此my_popupwindow_layout.xml文件中的文件夹res/layout，这是用来充气的popupWindow自定义布局。

<LinearLayout 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:orientation="horizontal" > 

    <Button 
     android:id="@+id/button1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="Window test" /> 
</LinearLayout>
