Question

下面是我的gridview布局，当我在其布局中添加按钮时它没有按钮正常工作它停止在gridview中选择clickany图像没有效果为什么/ ?? gridview有什么限制，不在其布局上添加按钮???这是我的屏幕截图imgur.com/jvGzpRP

        I'm changing from this:

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:orientation="vertical" >

 <ImageView
    android:id="@+id/image2"
    android:layout_width="wrap_content"
    android:layout_height="70dp"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    android:padding="5dp"
    android:scaleType="fitXY"
    android:src="@drawable/ic_launcher" />

 <TextView
    android:id="@+id/title2"
    android:layout_width="90dp"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal"
    android:paddingTop="10dp"
    android:textColor="#000" />

  </LinearLayout>

      To this:

  <LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:orientation="horizontal" >

 <ImageView
    android:id="@+id/image2"

 <LinearLayout
    android:layout_width="fill_parent"

        android:gravity="center_vertical"
        android:textColor="#000000" />

    <TextView

        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:gravity="center_vertical" />
 </LinearLayout>
  </LinearLayout>

   <LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0.5"

 <Button

    android:background="@drawable/roundshapebtn"
    android:text="Order Now"
    android:textColor="#ffffff"
