android 自定義baseadapter listview,Android 給listView設定自定義繼承BaseAdapter的adapter。給item設定監聽的問題...

為什麼 final String u_id = customerComment.getU_id();

String t_id = customerComment.getU_id();

同樣是customerComment.getU_id();擷取出來的，輸出來的值是不一樣的。在onClickListen裡面的t_id始終是data.get(0).getU_id()?而在onClickListen外面的是正常的。

也就是在監聽事件裡通路外部類的全局變量customerComment時，始終是data的第一個 customerComment。

public class CommentAdapter extends BaseAdapter {

List data = new ArrayList();

CustomerComment customerComment;

private Context context;

private ImageLoad imageLoad;

public CommentAdapter() {

}

public CommentAdapter(Context context) {

this.context = context;

imageLoad = new ImageLoad(context);

}

public CommentAdapter(List data, Context context) {

this.data = data;

this.context = context;

imageLoad = new ImageLoad(context);

}

@Override

public int getCount() {

return data.size();

}

@Override

public Object getItem(int position) {

return data.get(position);

}

@Override

public long getItemId(int position) {

return position;

}

@Override

public View getView(int position, View convertView, ViewGroup parent) {

if (convertView == null) {

convertView = View.inflate(context, R.layout.community_comment_item, null);

}

customerComment = data.get(position);

//這裡！！！！！！！！

** final String u_id = customerComment.getU_id();**

ImageView headpic = convertView.findViewById(R.id.headpic);

TextView name = convertView.findViewById(R.id.name);

TextView publishtime = convertView.findViewById(R.id.publishtime);

TextView comment = convertView.findViewById(R.id.comment);

name.setText(customerComment.getName());

publishtime.setText(customerComment.getTime());

comment.setText(customerComment.getContent());

//頭像點選事件，跳到使用者的首頁

headpic.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

Intent intent = new Intent();

intent.setClass(context, UserHomePage.class);

//這裡！！！！！！！！

String t_id = customerComment.getU_id();

System.out.println(t_id+","+u_id);

intent.putExtra("u_id",u_id);

context.startActivity(intent);

}

});

imageLoad.loadImage(headpic,context.getString(R.string.server_projectpath)+customerComment.getHeadPicPath());

return convertView;

}

}
