Android 开发的猜拳游戏

Android开发的猜拳游戏：

1、XML实现的主UI界面代码

在这里也可以用线性布局来实现，总体为水平线性布局，中间的部分用垂直线性布局

后面两个按钮也可以用垂直线性布局！

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>

2、主界面的java代码

package com.Jackson.game;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.ImageView;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.TextView;

public class Caiquan extends Activity {
	 private RadioGroup radioGroup1,radioGroup;
     private RadioButton shitouButton1,buButton1,jiandaoButton1;
     private RadioButton jiandaoButton,buButton,shitouButton;
     private Button button1,button2;
     private TextView textview1,textview;
     private ImageView imageview;
     private ImageView imageview1;
    
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_caiquan);
		
		textview1=(TextView)findViewById(R.id.textView1);
		textview=(TextView)findViewById(R.id.game);
		
		button1 = (Button) findViewById(R.id.button1);
		button2 = (Button) findViewById(R.id.button2);
		button1.setOnClickListener(new ButtonListener());
		button2.setOnClickListener(new ButtonListener());
		
		radioGroup=(RadioGroup)findViewById(R.id.radioGroupId);
		radioGroup1=(RadioGroup)findViewById(R.id.radioGroupId1);
		
		shitouButton1=(RadioButton)findViewById(R.id.radioButton1);
		buButton1=(RadioButton)findViewById(R.id.radioButton3);
		jiandaoButton1=(RadioButton)findViewById(R.id.radioButton5);
		jiandaoButton=(RadioButton)findViewById(R.id.radioButton2);
		shitouButton=(RadioButton)findViewById(R.id.radioButton4);
		buButton=(RadioButton)findViewById(R.id.radioButton6);
		RadioButtonListener Radiolistener = new RadioButtonListener();
		shitouButton1.setOnCheckedChangeListener(Radiolistener);
		buButton1.setOnCheckedChangeListener(Radiolistener);
		jiandaoButton1.setOnCheckedChangeListener(Radiolistener);
		jiandaoButton.setOnCheckedChangeListener(Radiolistener);
		shitouButton.setOnCheckedChangeListener(Radiolistener);
		buButton.setOnCheckedChangeListener(Radiolistener);
		
		imageview1 = (ImageView) findViewById(R.id.imageView1);
		imageview = (ImageView) findViewById(R.id.imageView2);
		   //在这里也可以为findViewById方法和绑定监听器设置两个方法
	}
		class RadioButtonListener implements  OnCheckedChangeListener{
			public void onCheckedChanged(CompoundButton buttonView,
					boolean isChecked) {
				System.out.println("is Checkede---->"  +isChecked);
			}
		}

			
		class ButtonListener implements OnClickListener{

				@Override
				public void onClick(View v) {
					RadioButton radioButtonleft = (RadioButton) findViewById(radioGroup1
					   .getCheckedRadioButtonId());
					 String radioTextleft = radioButtonleft.getText().toString();
					RadioButton radioButtonright = (RadioButton) findViewById(radioGroup
							   .getCheckedRadioButtonId());
					String radioTextright = radioButtonright.getText().toString();
					Intent intent= new Intent();
					intent.setClass(Caiquan.this, Next.class);

										//用radioText记录被选中的单选按钮的值，传达到下一个Activity
					intent.putExtra("checkedleft", radioTextleft);
					intent.putExtra("checkedright", radioTextright);
					startActivity(intent);
				}
			}

	public boolean onCreateOptionsMenu(Menu menu) {
		// Inflate the menu; this adds items to the action bar if it is present.
		getMenuInflater().inflate(R.menu.caiquany, menu);
		return true;
	}

	public boolean onOptionsItemSelected(MenuItem item) {
		// Handle action bar item clicks here. The action bar will
		// automatically handle clicks on the Home/Up button, so long
		// as you specify a parent activity in AndroidManifest.xml.
		 int id = item.getItemId();
		if (id == R.id.action_settings) {
			return true;
		}
		return false;
}}

3、点击确定后跳转到的下一个界面

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="174dp"
        android:text="TextView" 
        android:textSize="45sp"/>

    <Button
        android:id="@+id/button3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/textView1"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="69dp"
        android:text=" " />

</RelativeLayout>

4、下一个界面对应的java代码

package com.Jackson.game;

import android.app.Activity;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class Next extends Activity{
	
	private TextView textView;
	private Button button;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.next);
		
		button=(Button)findViewById(R.id.button3);
		button.setOnClickListener((android.view.View.OnClickListener) new ButtonLisener());
		
		textView=(TextView)findViewById(R.id.textView1);
	}
	
	class ButtonLisener implements OnClickListener{

		@Override
		public void onClick(DialogInterface dialog, int which) {
			  Intent intent = getIntent();
			  String checkedleft = intent.getStringExtra("checkedleft");
			  String checkedright = intent.getStringExtra("checkedright");
			  
			  // 设置View为可见
			  textView.setVisibility(View.VISIBLE);
			  button.setVisibility(View.VISIBLE);
			  String msg = "左边：" + checkedleft + "\n" + "右边：" + checkedright
			   + "\n";
			  if (checkedleft.equals(checkedright)) {
			  textView.setText(msg + "平局");
			  }
			  if (checkedright.equals("石头"))  {
			  if (checkedleft.equals("剪刀")) { textView.setText(msg + "右边赢");}
			  else if (checkedleft.equals("布")) {textView.setText(msg + "左边赢"); }
			  }
			  if (checkedright.equals("剪刀")) {
			  if (checkedleft.equals("布")) {
			   textView.setText(msg + "右边赢");
			  } else if (checkedleft.equals("石头")) {
			   textView.setText(msg + "左边赢");
			  }
			  }
			  if (checkedright.equals("布")) 
			  {
			  if (checkedleft.equals("石头")) {
			   textView.setText(msg + "右边赢");
			  } 
			  else if (checkedleft.equals("剪刀")) {
			   textView.setText(msg + "左边赢");	 
			  }	  
			 }	
		}	
	}
}

猜拳游戏的基本思路

1、先设置好基本布局界面

2、思考猜拳的基本形式，怎样判断谁胜谁负？

3、怎样用java代码实现这种形式，要用到那些类？哪些方法？
