Android ListView点击关注或赞错位问题

刚才有个朋友问题，ListView的点击关注的错位问题，我思考了一下，贴上我的解决方法，希望对大家有用，如果有什么好的方法，欢迎大家留言指导我，谢谢哦！

话不多说，上代码：

1.先看activity_main_xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <ListView
        android:id="@+id/main_listview_id"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </ListView>

</LinearLayout>

2.再看main_listview_item.xml

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

    <TextView
        android:id="@+id/main_item_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:padding="10dp" >
    </TextView>

    <TextView
        android:id="@+id/main_item_type"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:padding="10dp" >
    </TextView>

</LinearLayout>

这两个视图很简单，我就不解释了。继续走

3.MainActivity.java

package com.example.androidtest;

import java.util.ArrayList;
import java.util.List;
import android.os.Bundle;
import android.app.Activity;
import android.widget.ListView;

public class MainActivity extends Activity {

	private List<UserBean> beans;
	private ListView listView;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		getListData();
		initView();
	}

	private void initView() {
		
		listView = (ListView) findViewById(R.id.main_listview_id);
		MainAdapter adapter = new MainAdapter(MainActivity.this, beans);
		listView.setAdapter(adapter);
	}

	private void getListData() {
		
		beans = new ArrayList<UserBean>();
		for (int i = 0; i < 20; i++) {
			UserBean bean = new UserBean();
			bean.setId("" + i);
			bean.setName("lbc" + i);
			beans.add(bean);
		}
	}
}

4.MainAdapter.java

package com.example.androidtest;

import java.util.ArrayList;
import java.util.List;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

public class MainAdapter extends BaseAdapter {

	private Context context;
	private List<UserBean> beans;
	private List<Boolean> booleans = new ArrayList<Boolean>();

	public MainAdapter(Context context, List<UserBean> beans) {
		super();
		this.context = context;
		this.beans = beans;
		for (int i = 0; i < beans.size(); i++) {
			booleans.add(false);
		}
	}

	@Override
	public int getCount() {
		return null == beans ? 0 : beans.size();
	}

	@Override
	public UserBean getItem(int position) {
		return beans.get(position);
	}

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

	@Override
	public View getView(int position, View v, ViewGroup parent) {
		ViewHolder holder;
		final int positions = position;
		if (null == v) {
			holder = new ViewHolder();
			v = LayoutInflater.from(context).inflate(
					R.layout.main_listview_item, null);
			holder.nameTv = (TextView) v.findViewById(R.id.main_item_name);
			holder.typeTv = (TextView) v.findViewById(R.id.main_item_type);
			v.setTag(holder);
		} else {
			holder = (ViewHolder) v.getTag();
		}

		holder.nameTv.setText(getItem(positions).getName());

		holder.typeTv.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				if (booleans.get(positions)) {
					booleans.set(positions, false);
				} else {
					booleans.set(positions, true);
				}
				notifyDataSetChanged();
			}
		});

		if (booleans.get(positions)) {
			holder.typeTv.setText("已关注");
		} else {
			holder.typeTv.setText("关注");
		}
		return v;
	}

	private class ViewHolder {

		TextView nameTv;
		TextView typeTv;
	}

}

5.UserBean.java

package com.example.androidtest;

public class UserBean {

	private String id;
	private String name;

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	@Override
	public String toString() {
		return "UserBean [id=" + id + ", name=" + name + "]";
	}

}

主要方法是在adapter中建立了一个List<Boolean>的list集合，然后在adapter中的两个if的作用。希望大家批评指正。谢谢
