android实现打地鼠游戏

今天上课老师用Java实现了打地鼠游戏的界面和具体逻辑，那么我也尝试使用Android语言实现其功能。

首先是打地鼠游戏的玩法

1.每隔1秒或者0.5秒地鼠会出现在九宫格中的任一位置
2.点击界面，如果地鼠出现的位置与点击位置相同，则认为打中地鼠。否则游戏继续。
3.打中地鼠后，游戏立即停止。

先上两张效果图

布局实现

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:orientation="vertical" >

 <LinearLayout
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:orientation="horizontal" >

 <Button
  android:layout_width="0dp"
  android:layout_height="wrap_content"
  android:layout_weight="1"
  android:onClick="start"
  android:text="开始" />

 <Button
  android:layout_width="0dp"
  android:layout_height="wrap_content"
  android:layout_weight="1"
  android:onClick="end"
  android:text="暂停" />
 </LinearLayout>

 <TableLayout
 android:layout_width="match_parent"
 android:layout_height="0dp"
 android:layout_weight="1" >

 <TableRow android:layout_weight="1" >

  <TextView
  android:id="@+id/text11"
  android:layout_width="wrap_content"
  android:layout_height="match_parent"
  android:layout_margin="3dp"
  android:layout_weight="1"
  android:background="#d2b48c"
  android:gravity="center" />

  <TextView
  android:id="@+id/text12"
  android:layout_width="wrap_content"
  android:layout_height="match_parent"
  android:layout_margin="3dp"
  android:layout_weight="1"
  android:background="#d2b48c"
  android:gravity="center" />

  <TextView
  android:id="@+id/text13"
  android:layout_width="wrap_content"
  android:layout_height="match_parent"
  android:layout_margin="3dp"
  android:layout_weight="1"
  android:background="#d2b48c"
  android:gravity="center" />
 </TableRow>

 <TableRow android:layout_weight="1" >

  <TextView
  android:id="@+id/text21"
  android:layout_width="wrap_content"
  android:layout_height="match_parent"
  android:layout_margin="3dp"
  android:layout_weight="1"
  android:background="#d2b48c"
  android:gravity="center" />

  <TextView
  android:id="@+id/text22"
  android:layout_width="wrap_content"
  android:layout_height="match_parent"
  android:layout_margin="3dp"
  android:layout_weight="1"
  android:background="#d2b48c"
  android:gravity="center" />

  <TextView
  android:id="@+id/text23"
  android:layout_width="wrap_content"
  android:layout_height="match_parent"
  android:layout_margin="3dp"
  android:layout_weight="1"
  android:background="#d2b48c"
  android:gravity="center" />
 </TableRow>

 <TableRow android:layout_weight="1" >

  <TextView
  android:id="@+id/text31"
  android:layout_width="wrap_content"
  android:layout_height="match_parent"
  android:layout_margin="3dp"
  android:layout_weight="1"
  android:background="#d2b48c"
  android:gravity="center" />

  <TextView
  android:id="@+id/text32"
  android:layout_width="wrap_content"
  android:layout_height="match_parent"
  android:layout_margin="3dp"
  android:layout_weight="1"
  android:background="#d2b48c"
  android:gravity="center" />

  <TextView
  android:id="@+id/text33"
  android:layout_width="wrap_content"
  android:layout_height="match_parent"
  android:layout_margin="3dp"
  android:layout_weight="1"
  android:background="#d2b48c"
  android:gravity="center" />
 </TableRow>
 </TableLayout>

</LinearLayout>

逻辑代码

需要实现每隔1秒绘制一次界面，且得确定更新地鼠的位置（这里我用的handler来发送循环消息实现的）

ArrayList<TextView>texts;//用来存放九个TextView
Handler handler = new Handler(new Callback() {
 @Override
 public boolean handleMessage(Message msg) {
  number = (int) (Math.random() * 8);
  System.out.println(number);
  for (int i = 0; i < arrays.length; i++) {
  if (i==number) {
   texts.get(i).setText("地鼠");
  }else {
   texts.get(i).setText("");
  }
  }
  handler.sendEmptyMessageDelayed(0, 500);
  return false;
 }
 });

这里单独写一个TextView的点击事件(一共九个)，这里需要注意的是，我给每个textview都赋给了一个值a，从0-8，当点击的textview值 a=（地鼠出现的位置）时，我们就可以认为打中了地鼠。

public void onClick(View v) {
 // TODO Auto-generated method stub
 switch (v.getId()) {
 case R.id.text11:
  if (number==0) {
  Toast.makeText(this, "打中地鼠了！。。。", 1).show();

  handler.removeMessages(0);
  }
  break;
 }
 }

最后贴上全部代码。
