android打地鼠游戏

在这次实现中，我没有采用线程实现，而是采用了递归的方式。

话不多说，贴源码：

//MainActivity.java代码package com.example.dell.ch4_10;import android.content.DialogInterface;import android.graphics.Color;import android.support.v7.app.AlertDialog;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.text.Html;import android.util.Log;import android.view.MotionEvent;import android.view.View;import android.widget.Button;import android.widget.ImageButton;import android.widget.LinearLayout;import android.widget.TextView;public class MainActivity extends AppCompatActivity {private int times = 30;private TextView textView;private ImageButton button1;private ImageButton button2;private int[] viewIds = new int[]{R.id.button1,R.id.button2,R.id.button3,R.id.button4,R.id.button5,R.id.button6,R.id.button7,R.id.button8,R.id.button9};private int[] flag = new int[]{0,0,0,0,0,0,0,0,0};private AlertDialog.Builder builder;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);textView = (TextView) findViewById(R.id.text);textView.setText(Html.fromHtml("请点击绿色按钮<font color='green'>"+times+"</font>次"));init();}public void init(){if(times == 0){builder = new AlertDialog.Builder(this);builder.setTitle("恭喜你，顺利过关。点一点很容易嘛！");builder.setIcon(R.mipmap.ic_launcher);builder.setPositiveButton("确定，再来一次！", null);builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {MainActivity.this.finish();}});builder.create().show();return ;}int ans = (int)(Math.random()*9);button1 = (ImageButton) findViewById(viewIds[ans]);button1.setImageResource(R.mipmap.cat);flag[ans] = 1;for(int i=0;i<viewIds.length;i++){button2 = (ImageButton) findViewById(viewIds[i]);final int temp = i;if(flag[temp] == 0){button2.setImageResource(R.mipmap.ic_launcher);}button2.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {if(flag[temp] == 1){times--;textView.setText(Html.fromHtml("请点击绿色按钮<font color='green'>"+times+"</font>次"));flag[temp] = 0;button2.setImageResource(R.mipmap.ic_launcher);init();}else{times--;textView.setText(Html.fromHtml("请点击绿色按钮<font color='green'>"+times+"</font>次"));builder = new AlertDialog.Builder(MainActivity.this);builder.setTitle("这么简单都输了！");builder.setIcon(R.mipmap.ic_launcher);builder.setPositiveButton("确定，再来一次！", null);builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {MainActivity.this.finish();}});builder.create().show();}}});}}}
