本文介绍了自定义弹出菜单样式的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我当前在弹出菜单中使用此样式:
I'm currently using this style for my popup menu:
<style name="mainActivityTheme" parent="Theme.MaterialComponents.Light.NoActionBar">
<item name="colorPrimary">@color/colorBlack</item>
<item name="colorPrimaryDark">@color/colorBlack</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
它如何使弹出菜单的顶部和底部有多余的空间:
How ever it causes popup menus to have extra space on the top and bottom:
我怎么做到的,所以没有多余的空间?是否有某种样式可以包裹内容?
How do I make it so there is no extra space? Is there a certain style so that it wraps its contents?
我忘了提及我以编程方式为视图充气,因此可能是个问题
private void inflateMoreMenu(View view){
PopupMenu popupMenu = new PopupMenu(mContext, view);
popupMenu.inflate(R.menu.popup_menu);
popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
switch (item.getItemId()){
case R.id.popup_menu_report:
//Inflate a layout
break;
case R.id.popup_menu_block:
//Inflate a layout
break;
}
return false;
}
});
@SuppressLint("RestrictedApi")
MenuPopupHelper menuHelper = new MenuPopupHelper(mContext, (MenuBuilder) popupMenu.getMenu(), view);
menuHelper.setForceShowIcon(true);
menuHelper.show();
}
用于popup_menu的XML:
XML for popup_menu:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/popup_menu_report"
android:title="Report"
android:icon="@drawable/icon_messages_report"/>
<item
android:id="@+id/popup_menu_block"
android:title="Block"
android:icon="@drawable/icon_alertdialog_block"/>
</menu>
推荐答案
对于OverflowMenu,您可以在应用程序主题中定义 actionOverflowMenuStyle
属性.
For the OverflowMenu you can define in your app theme the actionOverflowMenuStyle
attribute.
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight">
<item name="actionOverflowMenuStyle">@style/popupOverflowMenu</item>
</style>
使用:
<style name="popupOverflowMenu" parent="@style/Widget.MaterialComponents.PopupMenu.Overflow">
<item name="android:popupBackground">@drawable/my_mtrl_popupmenu_background</item>
</style>
drawable/my_mtrl_popupmenu_background.xml
文件:
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="?attr/colorSurface"/>
<corners
android:bottomLeftRadius="4dp"
android:bottomRightRadius="4dp"
android:topLeftRadius="4dp"
android:topRightRadius="4dp"/>
</shape>
原始文件中有 padding
:
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="?attr/colorSurface"/>
<corners
..../>
<padding
android:bottom="8dp"
android:top="8dp"/>
</shape>
对于弹出窗口,您可以使用:
For a popup you can use:
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight">
<item name="popupMenuStyle">@style/popupMenu</item>
</style>
<style name="popupMenu" parent="@style/Widget.MaterialComponents.PopupMenu">
<item name="android:popupBackground">@drawable/my_mtrl_popupmenu_background</item>
</style>
