今天在devp論壇裡看到有壇友問到九宮格的實現，我把我在項目中用的經驗分享一下。
代碼地址：http://download.csdn.net/detail/xyz_lmn/5151879
xml代碼：
android:numColumns="3" //九宮格的列數 auto_fit時為自動 android:listSelector="@drawable/grid_selector_background" //九宮格的背景，可以找個圓角正方形
public class NineBox extends Activity {
/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
