求助，大家给看看

本人刚刚开始学习Android，编写了一个小程序，用于计算两个数相乘，点击计算按钮后出现结果，但现在程序出了点问题，点击计算后没有任何反应，希望大家帮忙看看哪里出了问题
这里是Activity02:
package marc.Activity02;

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

public class Activity02 extends Activity {
/** Called when the activity is first created. */
private EditText factorOne;
private EditText factorTwo;
private TextView symbol;
private Button calculate;


@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

factorOne =(EditText)findViewById(R.id.factorOne);
factorTwo =(EditText)findViewById(R.id.factorTwo);
symbol =(TextView)findViewById(R.id.symbol);
calculate =(Button)findViewById(R.id.calculate);
symbol.setText(R.string.symbol);
calculate.setText(R.string.calculate);

calculate.setOnClickListener( new View.OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub

}
});
}






@Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add(0, 1, 1, R.string.exit);
menu.add(0, 2, 2, R.string.about);
return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
if(item.getItemId()==1){
finish();
}

return super.onOptionsItemSelected(item);
}



class CalculateListener implements OnClickListener{
public void onClick(View v) {
String factorOneStr=factorOne.getText().toString();
String factorTwoStr=factorTwo.getText().toString();
//将这两个的值存放到Intent对象当中
Intent intent=new Intent();
intent.putExtra("One", factorOneStr);
intent.putExtra("Two", factorTwoStr);
intent.setClass(Activity02.this,ResultActivity.class);
//使用这个Intent对象来启动ResultActivity
Activity02.this.startActivity(intent);

}

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub

}

}
}

这里是ResultActivity.java
package marc.Activity02;

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

public class ResultActivity extends Activity{
private TextView resultView;

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.result);
resultView = (TextView)findViewById(R.id.result);
Intent intent=getIntent();
String factorOneStr=intent.getStringExtra("one");
String factorTwoStr=intent.getStringExtra("two");
int factorOneInt=Integer.parseInt(factorOneStr);
int factorTwoInt=Integer.parseInt(factorTwoStr);

int result=factorOneInt * factorTwoInt;

resultView.setText(result + " ");

}


}
下面是两个layout
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<EditText
android:id="@+id/factorOne"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>

<TextView
android:id="@+id/symbol"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello"
/>
<EditText
android:id="@+id/factorTwo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
<Button
android:id="@+id/calculate"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>

这里是result.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id="@+id/result"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>

最后是AndroidMainfest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="marc.Activity02"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="10" />

<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".Activity02"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".ResultActivity"
android:label="@string/resultLabel"></activity>
</application>
<uses-sdk android:minSdkVersion="10"/>
</manifest>

calculate.setOnClickListener( new View.OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub

}
});
}
哥们，你自己写了个CalculateListener，怎么不calculate.setOnClickListener(new CalculateListener());
你上面设的监听器的匿名内部类onclick方法里木有操作呀。有木有

你去网上找一下Mars老师的视频，那上面讲的好像有两个数相乘这个例子，强烈推荐Mars老师的视频，看着很好的
