程序如下：

    package com.example.two;

 

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

 

import android.os.Bundle;

import android.os.Handler;

import android.os.Message;

import android.app.Activity;

import android.app.DatePickerDialog;

import android.app.Dialog;

import android.app.ExpandableListActivity;

import android.view.Menu;

import android.view.MenuItem;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Adapter;

import android.widget.ArrayAdapter;

import android.widget.AutoCompleteTextView;

import android.widget.Button;

import android.widget.DatePicker;

import android.widget.ProgressBar;

import android.widget.RatingBar;

import android.widget.SeekBar;

import android.widget.SimpleExpandableListAdapter;

import android.widget.Spinner;

import android.widget.TextView;

import android.support.v4.app.NavUtils;

 

public class MainActivity extends Activity {

private RatingBar ratingbar = null;

private TextView  text      = null;

@Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        text      = (TextView)findViewById(R.id.testrating);

        ratingbar = (RatingBar)findViewById(R.id.ratingbar);

        ratingbar.setOnRatingBarChangeListener(new RatingBarListener());

    }

  

@Override

    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.activity_main, menu);

        return true;

    }

class RatingBarListener implements RatingBar.OnRatingBarChangeListener{

 

  @Override

  public void onRatingChanged(RatingBar ratingBar, float rating,

    boolean fromUser) {

   // TODO Auto-generated method stub

   System.out.println("rating ---->"+rating);

  }

 

}

   

 

 

    class ButtonListener implements OnClickListener{

  @Override

  public void onClick(View v) {

   // TODO Auto-generated method stub

  } 

    }

}

布局文件如下：

 

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

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

 android:orientation="vertical"

    android:layout_height="match_parent" >

<TextView 

    android:id="@+id/testrating"

    android:layout_width="fill_parent"

    android:layout_height="wrap_content"

    android:text="@string/text"

    

    />

<RatingBar

    android:id="@+id/ratingbar"

    android:layout_width="wrap_content"

    android:layout_height="fill_parent"

    android:numStars="5"

    android:stepSize="0.5"

    />

</LinearLayout>

效果如下：
