三.Activity代码

package com.example.listviewandradiobutton;

import java.util.ArrayList;
import java.util.List;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.Button;
import android.widget.ListView;

public class MainActivity extends Activity {

	ListView listView;
	Button confirmBtn;
	ListAdapter listAdapter;
	List list;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.sms_model);

		Book[] books = new Book[] { new Book("java", "you", 2011),
				new Book("c++", "him", 2012), new Book("android", "she", 2013) };

		list = new ArrayList();
		for(Book book:books){
			list.add(book);
		}
		
		listView = (ListView) findViewById(R.id.sms_model_list);
		confirmBtn = (Button) findViewById(R.id.confirm_btn);

		listAdapter = new ListAdapter(MainActivity.this);
		listAdapter.setList(list);
		listView.setAdapter(listAdapter);
		
		final Intent intent = new Intent(MainActivity.this,NextActivity.class);
		intent.putExtra("selectedBook", "你还什么都没有选择!");
		listView.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView parent, View view,
					int position, long id) {
				listAdapter.select(position);
				
				Book book = (Book)listAdapter.getItem(position);
				String value = book.getBookName() + " " + book.getAuthor()
						+ " " + book.getPublishTime();
				intent.putExtra("selectedBook", value);
				
			}
		});
		
		confirmBtn.setOnClickListener(new View.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				startActivity(intent);
			}
		});

	}
}

 


 

package com.example.listviewandradiobutton;

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

public class NextActivity extends Activity{

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		String value = getIntent().getExtras().getString("selectedBook");
		TextView textView = new TextView(this);
		textView.setText(value);
		setContentView(textView);
	}
}


四.实体类代码

 

package com.example.listviewandradiobutton;

public class Book{

	private String bookName;
	private String author;
	private int publishTime;
	private boolean isSelected = false;
	public Book(){};
	
	public Book(String bookName,String author,int publishTime){
		this.bookName = bookName;
		this.author = author;
		this.publishTime = publishTime;
	}
	
	public String getBookName() {
		return bookName;
	}
	public void setBookName(String bookName) {
		this.bookName = bookName;
	}
	public String getAuthor() {
		return author;
	}
	public void setAuthor(String author) {
		this.author = author;
	}
	public int getPublishTime() {
		return publishTime;
	}
	public void setPublishTime(int publishTime) {
		this.publishTime = publishTime;
	}
	public boolean isSelected() {
		return isSelected;
	}
	public void setSelected(boolean isSelected) {
		this.isSelected = isSelected;
	}
}


五.ListAdapter代码

package com.example.listviewandradiobutton;

import java.util.List;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.RadioButton;
import android.widget.TextView;

public class ListAdapter extends BaseAdapter {

	Context context;
	LayoutInflater mInflater;
	ViewHolder holder;
	List Book;
	Book book;

	public ListAdapter(Context context) {
		this.context = context;
		this.mInflater = LayoutInflater.from(context);
	}

	public void setList(List Book) {
		this.Book = Book;
	}

	// 选中当前选项时,让其他选项不被选中
	public void select(int position) {
		if (!Book.get(position).isSelected()) {
			Book.get(position).setSelected(true);
			for (int i = 0; i < Book.size(); i++) {
				if (i != position) {
					Book.get(i).setSelected(false);
				}
			}
		}
		notifyDataSetChanged();
	}

	@Override
	public int getCount() {
		return Book.size();
	}

	@Override
	public Object getItem(int position) {
		return Book.get(position);
	}

	@Override
	public long getItemId(int position) {
		return position;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		if (convertView == null) {
			holder = new ViewHolder();
			convertView = mInflater.inflate(R.layout.sms_model_item, null);
			holder.radioBtn = (RadioButton) convertView
					.findViewById(R.id.radioButton);
			holder.radioBtn.setClickable(false);
			holder.textView = (TextView) convertView
					.findViewById(R.id.textView);
			convertView.setTag(holder);
		} else {
			holder = (ViewHolder) convertView.getTag();
		}
		book = (Book) getItem(position);
		holder.radioBtn.setChecked(book.isSelected());
		holder.textView.setText(book.getBookName() + " " + book.getAuthor()
				+ " " + book.getPublishTime());
		return convertView;
	}

	class ViewHolder {
		RadioButton radioBtn;
		TextView textView;
	}

}


六.AndroidManifest.xml中添加NextActivity




    

    
        
            
                

                
            
        
        
        
        
    



七.也算上吧,values包中的strings.xml




    ListViewAndRadioButton
    Settings
    Hello world!
    确定
