How to create a custom PopupMenu in Android
提问by lschlessinger
How can I replicate something like I made below in Balsamiq?
如何复制我在 Balsamiq 中制作的类似内容？
I made this menu, but it is only displaying the text of the items (not the icons). Is it possible to display both the title and icon in a PopupMenu?
我制作了这个菜单，但它只显示项目的文本（而不是图标）。是否可以在 PopupMenu 中同时显示标题和图标？
Here is my create_post_menu.xml
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>

以下是我的方法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);
}
}

I resolved this issue by simply putting the create_post_menuinside of the itemwhose icon is a +.
我简单地把解决这个问题create_post_menu的内部item，其图标是一个+。
For example, I have (using AppCompat):
例如，我有（使用 AppCompat）：
<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>
Without AppCompat, you could just get rid of the XML Namespace appby replacing appwith android.
如果没有 AppCompat，您可以app通过替换app为.xml 来摆脱 XML 命名空间android。
