GridView（网格布局）样例

属性：

这里写代码片1.Android:numColumns=”auto_fit”   //GridView的列数设置为自动2.android:columnWidth=”90dp "       //每列的宽度，也就是Item的宽度3.android:stretchMode=”columnWidth"//缩放与列宽大小同步4.android:verticalSpacing=”10dp”          //两行之间的边距5.android:horizontalSpacing=”10dp”      //两列之间的边距 6.android:cacheColorHint="#00000000" //去除拖动时默认的黑色背景7.android:listSelector="#00000000"        //去除选中时的黄色底色8.android:scrollbars="none"                   //隐藏GridView的滚动条9.android:fadeScrollbars="true"             //设置为true就可以实现滚动条的自动隐藏和显示10.android:fastScrollEnabled="true"      //GridView出现快速滚动的按钮(至少滚动4页才会显示)11.android:fadingEdge="none"                //GridView衰落(褪去)边缘颜色为空，缺省值是vertical。(可以理解为上下边缘的提示色)12.android:fadingEdgeLength="10dip"   //定义的衰落(褪去)边缘的长度13.android:stackFromBottom="true"       //设置为true时，你做好的列表就会显示你列表的最下面14.android:transcriptMode="alwaysScroll" //当你动态添加数据时，列表将自动往下滚动最新的条目可以自动滚动到可视范围内15.android:drawSelectorOnTop="false"  //点击某条记录不放，颜色会在记录的后面成为背景色,内容的文字可见(缺省为false)

自定义布局样式layout：item_gridview.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical" android:layout_width="match_parent"    android:layout_height="match_parent">    <ImageView        android:id="@+id/iv_img"        android:src="@drawable/benz"        android:layout_width="60dp"        android:layout_height="60dp"        android:layout_margin="10dp"/>    <TextView        android:id="@+id/tv_name"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="奔驰"        android:textSize="30sp"        android:layout_marginLeft="10dp"/></LinearLayout>

acvitity_gridview.xml设置GridView属性

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/activity_grid_bar"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.example.jump.GridBarActivity">    <!--显示3列（auto_fit自己适应屏幕），垂直距离为30dp-->    <GridView        android:id="@+id/gv"        android:numColumns="3"        android:verticalSpacing="30dp"        android:layout_width="match_parent"        android:layout_height="wrap_content">    </GridView></RelativeLayout>
