I'm trying to create a pop-up window in Android by clicking button in action bar. Like this:

在我的想法中，我在一个容器中实现了两个片段，其中1(弹出窗口)处于View.GONE状态，当我单击按钮时便可见.

In my idea I realised it with two fragments in one container, where 1 (pop-up) is in View.GONE state and becomes visible when I click button.

有没有更简单的方法来解决我的问题?

Is there an easier way to solve my problem?

推荐答案

基本上，您可以用很少的代码来完成此操作，最终您将像这样

但是如果要自定义，则必须设计自定义布局

but if you want to customize you have to design a custom layout

要实现这一目标，请创建一个如下所示的xml菜单文件

To Achieve that, create a xml menu file like below

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/search"
        android:icon="@android:drawable/ic_menu_search"
        android:title="Search"/>
    <item
        android:id="@+id/add"
        android:icon="@android:drawable/ic_menu_add"
        android:title="Add"/>
    <item
        android:id="@+id/edit"
        android:icon="@android:drawable/ic_menu_edit"
        android:title="Edit">
        <menu>
            <item
                android:id="@+id/share"
                android:icon="@android:drawable/ic_menu_share"
                android:title="Share"/>
        </menu>
    </item>

</menu>

现在，编写PopupMenu1 Activity.java文件

Now, write PopupMenu1 Activity.java file

package com.example.popuptest;

import android.app.Activity;
import android.os.Bundle;
import android.view.MenuItem;
import android.view.View;
import android.widget.PopupMenu;
import android.widget.Toast;

public class PopupMenu1 extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.popup_menu_1);
    }

    public void onPopupButtonClick(View button) {
        PopupMenu popup = new PopupMenu(this, button);
        popup.getMenuInflater().inflate(R.menu.popup, popup.getMenu());

        popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            public boolean onMenuItemClick(MenuItem item) {
                Toast.makeText(PopupMenu1.this,
                        "Clicked popup menu item " + item.getTitle(),
                        Toast.LENGTH_SHORT).show();
                return true;
            }
        });

        popup.show();
    }
}
