Question

I want to make an app where grid view will be there and when user click particular card he'll be redirected to particular website URL 
here I have used custom grid view with base adapter but how to redirect the user to particular site URL by onitemclicklistener 

我提供了图片附件，以了解制作此应用的实际目标

  

activity_main.xml

此代码实际上是为获取网格视图布局而编写的

       <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:background="#f8f8f8"
           android:orientation="vertical">

           <GridView
               android:id="@+id/customgrid"
               android:layout_width="match_parent"
               android:layout_height="wrap_content"
               android:layout_below="@+id/os_texts"
               android:numColumns="2" />


           <TextView
               android:id="@+id/os_texts"
               android:layout_width="match_parent"
               android:layout_height="70dp"
               android:layout_marginBottom="10dp"
               android:layout_marginTop="2dp"
               android:background="#ffffff"
               android:gravity="center"
               android:text="All In One Shopping"
               android:textAlignment="center"
               android:textSize="25dp" />
       </RelativeLayout>

  

items.xml

在这里，我为网格视图的特定卡片外观创建了单独的布局

       <?xml version="1.0" encoding="utf-8"?>
       <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
           xmlns:app="http://schemas.android.com/apk/res-auto"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:padding="3dp">

           <android.support.v7.widget.CardView
               android:layout_width="match_parent"
               android:layout_height="wrap_content"
               android:clickable="true"
               android:elevation="9dp"
               android:foreground="?android:attr/selectableItemBackground"
               app:cardCornerRadius="5dp"
               app:cardUseCompatPadding="true">

               <LinearLayout
                   android:layout_width="match_parent"
                   android:layout_height="wrap_content"
                   android:orientation="vertical">


                   <ImageView
                       android:id="@+id/os_images"
                       android:layout_width="match_parent"
                       android:layout_height="120dp"
                       android:scaleType="fitCenter"
                       android:src="@drawable/amazon" />

                   <View
                       android:layout_width="match_parent"
                       android:layout_height="1dp"
                       android:layout_marginLeft="10dp"
                       android:layout_marginRight="10dp"
                       android:background="#dadada">

                   </View>

                   <TextView
                       android:id="@+id/os_texts"
                       android:layout_width="match_parent"
                       android:layout_height="wrap_content"
                       android:layout_below="@+id/os_images"
                       android:layout_margin="10dp"
                       android:text="This is Just Dummy Text"
                       android:textAlignment="center"
                       android:textSize="18dp"
                       android:textStyle="bold" />

               </LinearLayout>

           </android.support.v7.widget.CardView>
       </RelativeLayout>
