C# + Xamarin开发Android应用 --- Tab的实现

Layout:

<?xml version="1.0" encoding="utf-8"?>
<TabHost xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/tabhost"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:padding="5dp">
        <TabWidget
            android:id="@android:id/tabs"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content" />
        <FrameLayout
            android:id="@android:id/tabcontent"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:padding="5dp" />
    </LinearLayout>
</TabHost>

创建CreateTab方法

private void CreateTab(Type activityType, string tag, string label, int drawableId)
        {
            var intent = new Intent(this, activityType);
            intent.AddFlags(ActivityFlags.NewTask);


            var spec = TabHost.NewTabSpec(tag);
            var drawableIcon = Resources.GetDrawable(drawableId);
            spec.SetIndicator(label, drawableIcon);
            spec.SetContent(intent);


            TabHost.AddTab(spec);
        }

 CreateTab(typeof(BusinessSearch), "Search", "Search", Resource.Drawable.abc_ab_share_pack_mtrl_alpha);
            CreateTab(typeof(MyOrders), "My Orders", "My Orders", Resource.Drawable.abc_btn_check_material);
