Question

我有一个ListView，每列包含三个TextViews（出于格式原因）。我遇到的问题是调用onItemClick方法时我需要返回所有三个TextViews的值，这是我无法实现的：

((TextView)view.).getText().toString();

Answer 1

尝试将id分配给TextViews，然后使用findViewById在视图中找到它们的行项目。例如：

public void onItemClick(AdapterView<?> parent, View child, int position, long id) {
    TextView titleTextView = (TextView)child.findViewById(R.id.textview_title);
    TextView subtitleTextView = (TextView)child.findViewById(R.id.textview_subtitle);
    TextView dateTextView = (TextView)child.findViewById(R.id.textview_date);

    // Do the rest of your processing here
}

Answer 2

访问TextView中的每个ListView，如下所示：

listView.setOnItemClickListener(new OnItemClickListener(){

    @Override
    public void onItemClick(AdapterView<?> parent, View viewItem, int position, long arg3) throws NullPointerException{

        TextView one = (TextView)parent.getChildAt(position-listView.getFirstVisiblePosition()).findViewById(R.id.tvone);
        String tvone = one.getText().toString();
        TextView two = (TextView)parent.getChildAt(position-listView.getFirstVisiblePosition()).findViewById(R.id.tvtwo);

        String tvtwo = two.getText().toString();
        TextView three = (TextView)parent.getChildAt(position-listView.getFirstVisiblePosition()).findViewById(R.id.tvthree);
        String tvthree = three.getText().toString();
    }
    }

Answer 3

最后，我发现这很完美：

String item = ((TextView)view.findViewById(R.id.TYPE_CELL)).getText().toString();

从ListView返回多个TextView值
