在这段代码中，我想将我的5个案例在开关条件* 中随机播放或随机化。点击更正按钮后，图像出现全屏并返回到相同的情况。相反，我想从余下的案件在随机。*如何在Switch状态下随机分配病例？
public class MainActivity extends Activity{
ImageButton ib1,ib2,ib3,ib4,ib5,ib6,ib7,ib8,ib9,ib10,ib11,ib12,ib13,ib14,ib15;
ImageView iv;
Handler handler = new Handler();
int x;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

嗨，正如我刚才提到的，在开关盒中，在开始活动时，出现了一个随机的情况。点击正确的按钮后，我想随机显示剩余的情况。但它只显示前一个案例 – sai 2013-03-18 09:18:35
