我目前在弹出菜单中使用此样式:
<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>
如何使弹出菜单的顶部和底部有多余的空间:
我怎么做,所以没有多余的空间?是否有某种样式可以包装内容?
编辑:我忘了提及我以编程方式给视图充气,因此可能是一个问题
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();
}
popup_menu的XML:
<?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>
最佳答案
对于“溢出菜单”,您可以在应用程序主题中定义actionOverflowMenuStyle
属性。
<style name="AppTheme" parent="Theme.MaterialComponents.DayNight">
<item name="actionOverflowMenuStyle">@style/popupOverflowMenu</item>
</style>
带有:
<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>
它的原始文件是
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:
<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>
