九宫格的实现及九宫格源码今天在坛子里看到有坛友问到九宫格的实现，我把我在项目中用的经验分享一下，九宫格用gridview实现代码如下：XML/HTML代码<?xmlversion="1.0"encoding="utf-8"?><LinearLayoutxmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res/com.google.android.gx5weather"android:orientation="vertical"android:layout_width="fill_parent"android:layout_height="fill_parent"android:layout_weight="1.0"android:background="@drawable/bg"><ImageViewandroid:id="@+id/ImageView01"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_vertical"android:background="@drawable/top"></ImageView><GridViewxmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/gridview"android:layout_width="wrap_content"android:layout_height="wrap_content"android:numColumns="3"android:verticalSpacing="30dip"android:horizontalSpacing="10dip"android:columnWidth="90dip"//列宽android:stretchMode="columnWidth"android:gravity="center"android:listSelector="@drawable/grid_selector_background"></GridView></LinearLayout>Android:numColumns="3"//九宫格的列数auto_fit时为自动android:listSelector="@drawable/grid_selector_background"//九宫格的背景，可以找个圆角正方形Java代码publicclassNineBoxextendsActivity{/**Calledwhentheactivityisfirstcreated.*/@OverrideprotectedvoidonCreate(BundlesavedInstanceState){//TODOAuto-generatedmethodstubsuper.onCreate(savedInstanceState);this.requestWindowFeature(Window.FEATURE_NO_TITLE);this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);setContentView(R.layout.main_activity);GridViewgridview=(GridView)findViewById(R.id.gridview);ArrayList<HashMap<String,Object>>lstImageItem=newArrayList<HashMap<String,Object>>();for(inti=1;i<10;i++){HashMap<String,Object>map=newHashMap<String,Object>();if(i==1){map.put("ItemImage",R.drawable.g11);map.put("ItemText",getResources().getString(R.string.gridview1));}if(i==2){map.put("ItemImage",R.drawable.g12);map.put("Item
