如何在Android中创建自定义PopupMenu

Question

我怎样才能复制下面在Balsamiq中制作的内容？

我制作了这个菜单，但它只显示了项目的文本（而不是图标）。是否可以在PopupMenu中显示标题和图标？

这是我的create_post_menu.xml

<?xml version="1.0" encoding="utf-8"?>

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

    <item
        android:id="@+id/action_photo"
        android:icon="@drawable/ic_action_camera"
        android:title="@string/action_photo"
        android:showAsAction="always|withText" />

    <item
        android:id="@+id/action_video"
        android:icon="@drawable/ic_action_video"
        android:title="@string/action_video"
        android:showAsAction="always|withText" />

    <item
        android:id="@+id/action_text"
        android:icon="@drawable/ic_action_edit"
        android:title="@string/action_text"
        android:showAsAction="always|withText" />

    <item
        android:id="@+id/action_link"
        android:icon="@drawable/ic_action_web_site"
        android:title="@string/action_link"
        android:showAsAction="always|withText" />

</menu>

修改

以下是我的onCreateOptionsMenu和onOptionsItemSelected方法：

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);
    return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    if (item.getItemId() == R.id.action_new) {
        View menuItemView = findViewById(R.id.action_new);
        PopupMenu popupMenu = new PopupMenu(this, menuItemView);
        popupMenu.inflate(R.menu.create_post_menu);
        popupMenu.show();
        return true;
    } else if(item.getItemId() == R.id.action_search) {
        return true;
    } else if(item.getItemId() == R.id.action_settings) {
        startActivity(new Intent(MainActivity.this, SettingsActivity.class));
        return true;
    } else if(item.getItemId() == R.id.action_help) {
        return true;
    } else {
        return super.onOptionsItemSelected(item);
    }
}

我通过简单地将create_post_menu放在图标为item的{​​{1}}内解决了这个问题。

例如，我（使用AppCompat）：

如果没有AppCompat，您可以通过将<menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"> <item android:id="@+id/action_new" android:icon="@drawable/ic_action_new" android:title="@string/action_new" app:showAsAction="always"> <menu> <item android:id="@+id/action_photo" android:icon="@drawable/ic_action_camera" android:title="@string/action_photo" app:showAsAction="always|withText" /> <item android:id="@+id/action_video" android:icon="@drawable/ic_action_video" android:title="@string/action_video" app:showAsAction="always|withText" /> <item android:id="@+id/action_text" android:icon="@drawable/ic_action_text" android:title="@string/action_text" app:showAsAction="always|withText" /> <item android:id="@+id/action_place" android:icon="@drawable/ic_action_place" android:title="@string/action_place" app:showAsAction="always|withText" /> <item android:id="@+id/action_more" android:title="@string/action_more" android:visible="false" app:showAsAction="always|withText" /> </menu> </item> ...(more menu items here) </menu> 替换为app来摆脱XML命名空间app。

             }  
            });  

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

我希望我之前的回答Here能为您提供帮助 如果您只想要一个类似的弹出菜单，可以使用ActionProvider。它更强大。
如果您希望它作为真正的菜单，您可以使用自定义PopupMenu。
