Android中listview条目中按钮点击事件的实现

大家都知道Android中listview是一个常用的控件，也是一个比较复杂的控件，一般实现listview的条目点击事件就是给listview实现setOnItemClickListener的方法就行，但是当我们遇到listview中的有按钮的时候想实现
按钮的点击事件这样做是不行的，比如QQ空间的说说评论和点赞其实就是相当于两个按钮。一般实现这两个按钮的点击事件归结为一种思想---接口回调。具体实现的话有两种方法，一中是通过实现接口方法，一中是通过实
现抽象方法。当然接口和抽象类在java中其实差不多的东西，虽然两者有很大不同，但是他们有着一样的功能。

两种方法都有实现，其中还应当注意一般每个控件都有一个setTag()的方法，这个方法在这中问题上起着至关重要的作用。一般可以用来记录按钮的位置之类的。

抽象类的实现：

package com.example.listviewbuttonclick.adapter;

import android.view.View;
import android.view.View.OnClickListener;

public abstract class IClick implements OnClickListener {
	@Override
	public void onClick(View v) {
		listViewItemClick((Integer) v.getTag(), v);
	}

	public abstract void listViewItemClick(int position, View v);

}

适配器

package com.example.listviewbuttonclick.adapter;

import java.util.List;

import com.example.listviewbuttonclick.R;

import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.TextView;

public class ContentAdapter extends BaseAdapter {

	private static final String TAG = "ContentAdapter";
	private List<String> mContentList;
	private LayoutInflater mInflater;
	private IClick mListener;

	public ContentAdapter(Context context, List<String> contentList,
			IClick listener) {
		mContentList = contentList;
		mInflater = LayoutInflater.from(context);
		mListener = listener;
	}

	@Override
	public int getCount() {
		Log.i(TAG, "getCount");
		return mContentList.size();
	}

	@Override
	public Object getItem(int position) {
		Log.i(TAG, "getItem");
		return mContentList.get(position);
	}

	@Override
	public long getItemId(int position) {
		Log.i(TAG, "getItemId");
		return position;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		Log.i(TAG, "getView");
		ViewHolder holder = null;
		if (convertView == null) {
			convertView = mInflater.inflate(R.layout.list_item, null);
			holder = new ViewHolder();
			holder.textView = (TextView) convertView
					.findViewById(R.id.textView1);
			holder.button = (Button) convertView.findViewById(R.id.button1);
			convertView.setTag(holder);
		} else {
			holder = (ViewHolder) convertView.getTag();
		}
		holder.textView.setText(mContentList.get(position));
		holder.button.setOnClickListener(mListener);
		holder.button.setTag(position);
		return convertView;
	}

	public class ViewHolder {
		public TextView textView;
		public Button button;
	}

}

接口实现

package com.example.listviewbuttonclick.adapter.inter;

import android.view.View;

public interface InterClick {
	public void commentClick(View v);

	public void shareClick(View v);

}

适配器

package com.example.listviewbuttonclick.adapter;

import java.util.List;

import com.example.listviewbuttonclick.R;
import com.example.listviewbuttonclick.adapter.inter.InterClick;

import android.content.Context;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.TextView;

public class ContentAdapter extends BaseAdapter implements OnClickListener {

	private static final String TAG = "ContentAdapter";
	private List<String> mContentList;
	private LayoutInflater mInflater;
	private InterClick mCallback;

	public ContentAdapter(Context context, List<String> contentList,
			InterClick callback) {
		mContentList = contentList;
		mInflater = LayoutInflater.from(context);
		mCallback = callback;
	}

	@Override
	public int getCount() {
		Log.i(TAG, "getCount");
		return mContentList.size();
	}

	@Override
	public Object getItem(int position) {
		Log.i(TAG, "getItem");
		return mContentList.get(position);
	}

	@Override
	public long getItemId(int position) {
		Log.i(TAG, "getItemId");
		return position;
	}

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		Log.i(TAG, "getView");
		ViewHolder holder = null;
		if (convertView == null) {
			convertView = mInflater.inflate(R.layout.list_item, null);
			holder = new ViewHolder();
			holder.textView = (TextView) convertView
					.findViewById(R.id.textView1);
			holder.button1 = (Button) convertView.findViewById(R.id.button1);
			holder.button2 = (Button) convertView.findViewById(R.id.button2);

			convertView.setTag(holder);
		} else {
			holder = (ViewHolder) convertView.getTag();
		}
		holder.textView.setText(mContentList.get(position));
		holder.button1.setOnClickListener(this);
		holder.button2.setOnClickListener(this);

		// 设置位置，获取点击的条目按钮
		holder.button1.setTag(position);
		holder.button2.setTag(position);
		return convertView;
	}

	public class ViewHolder {
		public TextView textView;
		public Button button1;
		public Button button2;

	}

	// 响应按钮点击事件,调用子定义接口，并传入View
	@Override
	public void onClick(View v) {
		switch (v.getId()) {
		case R.id.button1:
			mCallback.commentClick(v);
			break;
		case R.id.button2:
			mCallback.shareClick(v);
			break;
		default:
			break;
		}
	}
}

这两种分别是不同的方法实现的按钮点击事件，具体实现都在源码中
