Android如何实现九宫格
操作方法
- 01
本文需要添加/修改3个文件：main.xml、meunitem.xml、Java源代码。main.xml源代码如下，本身是个GirdView，用于装载Item：<?xml version="1.0" encoding="utf-8"?><GridView xmlns:Android="http://schemas.android.com/apk/res/android" android:id="@+id/GridView" android:layout_width="fill_parent" android:layout_height="fill_parent" android:numColumns="auto_fit" android:horizontalSpacing="10dp" android:verticalSpacing="10dp" android:columnWidth="90dp" android:stretchMode="columnWidth" android:gravity="center"></GridView>介绍一下里面的某些属性：android:numColumns="auto_fit" ，GridView的列数设置为自动android:columnWidth="90dp"，每列的宽度，也就是Item的宽度android:stretchMode="columnWidth"，缩放与列宽大小同步android:verticalSpacing="10dp"，两行之间的边距，如：行一(NO.0~NO.2)与行二(NO.3~NO.5)间距为10dpandroid:horizontalSpacing="10dp"，两列之间的边距。接下来介绍 meunitem.xml，这个XML跟前面ListView的ImageItem.xml很类似：<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="wrap_content"><ImageView android:layout_width="wrap_content" android:id="@+id/ItemImage" android:layout_height="wrap_content" android:layout_centerHorizontal="true"/><TextView android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_below="@+id/ItemImage"android:id="@+id/ItemText"android:layout_centerHorizontal="true"/></RelativeLayout> 最后是JAVA的源代码@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.mainmenu);GridView gridview = (GridView) findViewById(R.id.GridView);ArrayList<HashMap<String, Object>> meumList = new ArrayList<HashMap<String, Object>>();for(int i = 1;i < 10;i++) {HashMap<String, Object> map = new HashMap<String, Object>();map.put("ItemImage", R.drawable.icon);map.put("ItemText", "NO."+i);meumList.add(map);}SimpleAdapter saMenuItem = new SimpleAdapter(this, meumList, //数据源 R.layout.menuitem, //xml实现 new String[]{"ItemImage","ItemText"}, //对应map的Key new int[]{R.id.ItemImage,R.id.ItemText}); //对应R的Id//添加Item到网格中gridview.setAdapter(saMenuItem);gridview.setOnItemClickListener(new OnItemClickListener() {public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) { System.out.println("click index:"+arg2);
