本文探讨了在Android适配器的getView方法中设置点击监听的两种不同方式，一种直接给convertView设置监听器，另一种则通过其子View设置。详细分析了为何前者在某些情况下可能不生效的原因，并对比了两者的实现细节。

下面是我写的两个适配器adapter中的getView方法，第一个给convertView直接设置点击监听不起作用，第二个却可以点击，这是为什么呢？

@Override
public View getView(final int position, View convertView, ViewGroup viewGroup) {
ViewHolder viewHolder;
if (convertView == null) {
    viewHolder = new ViewHolder();
    convertView = LayoutInflater.from(context).inflate(R.layout.activity_my_borrow_money_list,viewGroup, false);

    viewHolder.tv2 = convertView.findViewById(R.id.tv_borrow2);
    viewHolder.tv3 = convertView.findViewById(R.id.tv_borrow3);
    viewHolder.tv4 = convertView.findViewById(R.id.tv_borrow4);
    viewHolder.rl = convertView.findViewById(R.id.rl_borrow_money_list);
    convertView.setTag(viewHolder);
} else {
    viewHolder = (ViewHolder) convertView.getTag();
}
String JKStatus = list.get(position).getHkschedule();
if ("0".equals(JKStatus)){
    viewHolder.tv2.setText("XXX");
    viewHolder.tv2.setTextColor(context.getResources().getColor(R.color.titleColor));
}else if ("1".equals(JKStatus)){
    viewHolder.tv2.setText("XXX");
    viewHolder.tv2.setTextColor(context.getResources().getColor(R.color.colorc7c7c7));
}else if ("2".equals(JKStatus)){
    viewHolder.tv2.setText("XXX");
    viewHolder.tv2.setTextColor(context.getResources().getColor(R.color.titleColor));
}else if ("3".equals(JKStatus)){
    viewHolder.tv2.setText("XXX");
    viewHolder.tv2.setTextColor(context.getResources().getColor(R.color.titleColor));
}
viewHolder.tv3.setText(list.get(position).getJkamount());

//        viewHolder.rl.setOnClickListener(new View.OnClickListener() {
//            @Override
//            public void onClick(View v) {
//                Log.e("test","222222");
//                Intent intent = new Intent(context, MyBorrowMoneyXiangqingActivity.class);
//                intent.putExtra("data", list.get(position).getId());
//                context.startActivity(intent);
//            }
//        });
convertView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Log.e("test","222222");
        Intent intent = new Intent(context, MyBorrowMoneyXiangqingActivity.class);
        intent.putExtra("data", list.get(position).getId());
        context.startActivity(intent);
    }
});

return convertView;
}

下面这个点击可以跳转

@Override
public View getView(int postition, View convertView, ViewGroup arg2) {
ViewHoler viewHolder = null;
if (convertView == null) {
    viewHolder = new ViewHoler();
    convertView = mInflater.inflate(R.layout.adapter_market, null);
    viewHolder.logo = (ImageView) convertView.findViewById(R.id.logo);
    viewHolder.title = (TextView) convertView.findViewById(R.id.title);
    viewHolder.money_number = (TextView) convertView
            .findViewById(R.id.money_number);
    convertView.setTag(viewHolder);
} else {
    viewHolder = (ViewHoler) convertView.getTag();
}
final MarketPojo data = pojo.get(postition);
ImageLoader.getInstance().displayImage(data.getLogo(),
        viewHolder.logo);
viewHolder.title.setText(data.getTitle());
viewHolder.money_number.setText(data.getAdvantage());
convertView.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        Intent intent = new Intent(context, ProblemActivity.class);
        intent.putExtra("title", data.getTitle());
        intent.putExtra("url",data.getUrl());
        context.startActivity(intent);
    }
});
return convertView;
}
