如何在弹出菜单中自定义menuItem？我需要第一个menuitem的开关.这是我到目前为止所得到的：
menu.xml文件
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="android.oli.com.fitnessapp.activities.LiveSelectActivity">
<item
android:icon="@drawable/ic_access_alarm_white_24dp"
android:orderInCategory="100"
app:showAsAction="always"
android:visible="true"
android:title="@string/action_settings"
android:onClick="showPopup"/>
</menu>
menu_popup.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/one"
android:title="One"/>
<item
android:id="@+id/setTime"
android:title="Two"
android:onClick="showTimePickerDialog"/>
</menu>
活动代码段
public void showPopup(MenuItem menuItem){
View view = findViewById(R.id.action_alarm);
PopupMenu popup = new PopupMenu(this,view);
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.menu_popup,popup.getMenu());
popup.show();
}
解决方法
您可以使用popupwindow,因为它允许使用自定义布局.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:padding="5dp">
<Switch
android:id="@+id/mySwitch"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="20dp"
android:text="Play with the Switch" />
<TextView
android:id="@+id/switchStatus"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/mySwitch"
android:layout_marginTop="22dp"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>
并在ur活动中实现此方法：
/* you should refer to a view to stick your popup wherever u want.
** e.g. Button button = (Button) findviewbyId(R.id.btn);
** if(popupWindow != null)
** showPopup(button);
**/
public void showPopup(View v) {
LayoutInflater layoutInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View popupView = layoutInflater.inflate(R.layout.popup_filter_layout,null);
popupWindow = new PopupWindow(
popupView,ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setBackgroundDrawable(new BitmapDrawable());
popupWindow.setoutsidetouchable(true);
popupWindow.setondismissListener(new PopupWindow.OndismissListener() {
@Override
public void ondismiss() {
//Todo do sth here on dismiss
}
});
popupWindow.showAsDropDown(v);
}
