Gmail like navigation drawer (master page) in xamarin.forms

问题

I am currently using the master-detail page in xamarin.forms using MVVMlight and it renders based on the default behavior of os it renders perfectly what I wanted but in android master page starts below the navigation bar. I wanted master page to cover full height of screen just like ios do so is there any way or solution for it without custom renderer or is it necessary to write custom renderer for this

Use FormsAppCompatActivity instead of FormsApplicationActivity.

define your own toolbar.axml

toolbar.axml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:minHeight="?attr/actionBarSize"
    android:contentInsetStart="0dp"
    android:contentInsetLeft="0dp"
    app:contentInsetLeft="0dp"
    app:contentInsetStart="0dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    app:layout_scrollFlags="scroll|enterAlways">
</android.support.v7.widget.Toolbar>

Set your own ToolbarResource

public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
    {
        protected override void OnCreate(Bundle bundle)
        {
            ToolbarResource = Resource.Layout.toolbar;
            base.OnCreate(bundle);
            global::Xamarin.Forms.Forms.Init(this, bundle);
            LoadApplication(new App());
        }
    }

Yes you can. Check these links. They all use the MasterDetail page to create a Navigation Drawer. Only the Detail page becomes the main page view and the Master page becomes the sliding Menu. It is actually fairly simple. There are a couple of other good example out there also. However I think you can get the job done from the 3 links I listed. If not try a Search like How can I create a Navigation Drawer in Xamarin Forms.
