这是两个java文件

MainActivity.java

package com.example.finger_guessing.activity;

import com.example.finger_guessing.R;

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

public class MainActivity extends Activity {
    private Button btnST,btnJD,btnB,btnSubmit;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.setContentView(R.layout.activity_main);

        this.btnST=(Button)findViewById(R.id.btnST);
        this.btnJD=(Button)findViewById(R.id.btnJD);
        this.btnB=(Button)findViewById(R.id.btnB);

        this.btnSubmit.setOnClickListener(new ViewOcl());

    }
    private class ViewOcl implements View.OnClickListener{
        @Override
        public void onClick(View v){
            int iComPlay = (int)(Math.random()*3+1);
            String jieguo;
            Bundle b=new Bundle();
            switch(v.getId()){
            case R.id.btnST:

                if(iComPlay==1){
                    jieguo="平局";
                    b.putString("jieguo", jieguo);
                }
                else if(iComPlay==2){
                    jieguo="胜利";
                    b.putString("jieguo", jieguo);

                    b.putString("jieguo", jieguo);
                }
                else if(iComPlay==2){
                    jieguo="平局";
                    b.putString("jieguo", jieguo);
                }
                else
                    jieguo="胜利";
                    b.putString("jieguo", jieguo);
                break;
            case R.id.btnB:
                if(iComPlay==1){
                    jieguo="失败";
                    b.putString("jieguo", jieguo);
                }
                else if(iComPlay==2){
                    jieguo="胜利";
                    b.putString("jieguo", jieguo);
                }
                else
                    jieguo="平局";
                    b.putString("jieguo", jieguo);
                break;
            case R.id.btnSubmit:
                Intent intent=new Intent();
                intent.setClass(MainActivity.this, ResultActivity.class);
                startActivity(intent);
            }
        }
    }


}

ResultActivity.java

package com.example.finger_guessing.activity;

import com.example.finger_guessing.R;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.*;

public class ResultActivity extends Activity {
    private TextView textResult,textComselect;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        this.setContentView(R.layout.activity_result);
        this.textComselect=(TextView)this.findViewById(R.id.textComselect);
        this.textResult=(TextView)this.findViewById(R.id.textResult);

        Intent intent=this.getIntent();
        Bundle extras=intent.getExtras();
        String jieguo=extras.getString("jieguo");

        this.textResult.setText(jieguo);
    }

这个是Manifest.xml

<manifest xmlns:android="http://schemas.
    package="com.example.finger_guessing"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

         <activity android:name="com.example.finger_guessing.activity.MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <activity android:name="com.example.finger_guessing.activity.ResultActivity"/>

刚刚学习Android不久。就自己练习着写了一个小练习。一运行的时候程序就意外停止。找了好久也没有找到问题出在哪里。

</LinearLayout>

ps:刚刚写的，你对着看下吧，一般listener写在Activity中作为内部类，结果的判断一般不使用activity，activity是作为一个view的作用，逻辑你可以写在control里面
