Android listView 中响应Button点击事件

其实很简单就是在getView中给button添加接口

public class Task_list_single_item_adapter extends BaseAdapter
{

	LayoutInflater inflater;
	Context context;
	public Task_list_single_item_adapter(Context context){
		this.context=context;
		inflater=LayoutInflater.from(context);
	}
	@Override
	public int getCount()
	{
		return 2;
	}

	@Override
	public Object getItem(int position)
	{
		return null;
	}

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

	@Override
	public View getView(int position, View convertView, ViewGroup parent)
	{
		final Holder holder;
		if(convertView!=null)
		{
			holder=(Holder) convertView.getTag();
		}else {
			holder=new Holder();
			convertView=inflater.inflate(R.layout.download_management_item, null);
			holder.pause=(Button) convertView.findViewById(R.id.dmi_ib1_pause);
			holder.trys=(Button) convertView.findViewById(R.id.dmi_ib2_recover);
			holder.install=(Button) convertView.findViewById(R.id.dmi_ib3_install);
			convertView.setTag(holder);
		}
		OnClickListener listener=new OnClickListener(){
			@Override
			public void onClick(View v)
			{
				if(v==holder.pause){
					Toast.makeText(context, "pause", Toast.LENGTH_SHORT).show();
					holder.pause.setVisibility(View.GONE);
					holder.trys.setVisibility(View.VISIBLE);
					holder.install.setVisibility(View.GONE);
				}
				if(v==holder.trys){
					Toast.makeText(context, "try", Toast.LENGTH_SHORT).show();
					holder.pause.setVisibility(View.VISIBLE);
					holder.trys.setVisibility(View.GONE);
					holder.install.setVisibility(View.GONE);
				}
				if(v==holder.install)
					Toast.makeText(context, "install", Toast.LENGTH_SHORT).show();
					
			}
		};
		holder.pause.setOnClickListener(listener);
		holder.trys.setOnClickListener(listener);
		holder.install.setOnClickListener(listener);
		return convertView;
	}
	class Holder{
		public Button pause;
		public Button trys;
		public Button install;
	}
}
