实现Android九宫格布局的代码

实现九宫格的三个文件：HomeActivity.java

public class HomeActivity extends Activity {
private GridView list_home;
private MyAdapter adapter;
private static String [] names = {
"手机防盗","通讯卫士","软件管理",
"进程管理","流量统计","手机杀毒",
"缓存清理","高级工具","设置中心"

};

private static int[] ids = {
R.drawable.safe,R.drawable.callmsgsafe,R.drawable.app,
R.drawable.taskmanager,R.drawable.netmanager,R.drawable.trojan,
R.drawable.sysoptimize,R.drawable.atools,R.drawable.settings

};

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
list_home = (GridView) findViewById(R.id.list_home);
adapter = new MyAdapter();
list_home.setAdapter(adapter);

}

private class MyAdapter extends BaseAdapter{
@Override
public int getCount() {
return names.length;
}

@Override
public Object getItem(int i) {
return null;
}

@Override
public long getItemId(int i) {
return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View view = View.inflate(HomeActivity.this, R.layout.list_item_home, null);
ImageView iv_item = (ImageView) view.findViewById(R.id.iv_item);
TextView tv_item = (TextView) view.findViewById(R.id.tv_item);

tv_item.setText(names[position]);
iv_item.setImageResource(ids[position]);
return view;
}
}
}

activity_home.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">

<GridView
android:layout_marginTop="15dp"
android:verticalSpacing="15dp"
android:numColumns="3"
android:id="@+id/list_home"
android:layout_width="match_parent"
android:layout_height="match_parent">

</GridView>
</LinearLayout>

list_item_home.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center">

<ImageView
android:id="@+id/iv_item"
android:layout_width="60dip"
android:layout_height="60dip"
android:src="@drawable/app" />

<TextView
android:id="@+id/tv_item"
android:textColor="#000000"
android:textSize="16sp"
android:text="手机防盗"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

</LinearLayout>

另附gridview的一些属性:1.android:numColumns=”auto_fit”   //GridView的列数设置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"        //设置item选中时的背景颜色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)参考：http://blog.csdn.net/ztp800201/article/details/14469883
