Question

我有一个列表视图，其中我使用多个textview和按钮来扩展布局。我理解从点击的视图中获取文本((Textview)view...。但是，我试图从位于用户单击的布局中的特定textview获取文本。我尝试过使用OnItemClick但是当我使用它时，必须在任何按钮功能工作之前聚焦项目。我使用并优先在我的自定义适配器的getView方法中使用onClickListeners。简单地说，如果因为每个膨胀的布局被视为一个列表项，我如何单击一个Button并获取TextView中位于相应的膨胀布局列表视图项中的文本？

这是照片，以澄清我在寻找什么。两种布局都是列表视图的成员。 enter image description here

我想单击带有日期的按钮，并从布局中间的textview中获取文本。但是，当我单击带有日期的按钮时，我只能从最后一个孩子的布局中间的textview中获取文本。如果＆＃34;我的党＆＃34;是列表视图中的第一个孩子，＆＃34; 3303离开服务...＆＃34;是第二个孩子，当我点击日期按钮时，我的自定义适配器中的代码返回视图中最后加载的文本中的文本，这将是＆＃34; 3303离开服务＆＃34;。我想要做的是当我点击＆＃34;我的派对＆＃34;上的日期按钮，得到文字＆＃34;我的派对＆＃34;。和第二个孩子一样聪明。

这是我的自定义适配器中的getView（）。

Answer 1

创建自定义baseadapter并在适配器的文本视图上单击侦听器。然后将为与位置对应的特定文本视图设置此项。

Answer 2

我认为您已经在要将点击注册到的textview的自定义BaseAdapter setOnclicklistener中创建了自定义BaseAdapter。

以下示例代码

public class M_Adapter extends BaseAdapter {
    private LayoutInflater inflater = null;
    private TextView contact_name;
    private Context context;
    private List<String> list;
    private List<String> temp;
    private Button btn;

    public M_Adapter(Context context) {
        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        try {
            list = new ArrayList<String>();
            //add some values in list here
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public int getCount() {
        return list.size();
    }

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

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

    @Override
    public View getView(int position, final View convertView, ViewGroup parent) {
        final View rowview = inflater.inflate(R.layout.contact_listrow, parent, false);
        contact_name = (TextView) rowview.findViewById(R.id.excl_ppl_contact_name);
        btn=(Button)rowview.findViewById(R.id.excl_ppl_btn);
        contact_name.setText(list.get(temp));

        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
            Log.v("myapp", "text clicked " + contact_name.getText());
            }
        });
        return rowview;
    }

}

我用两个if / else语句系列解决了这个问题。首先，在我的onBindViewHolder（你的getView）中我有一些全局的String变量采用我感兴趣的TextView的值。其次，在onClick方法中，我让ViewHolder告诉我使用getPosition点击项目的位置方法。最后，我将点击的位置值与第一部分中创建的字符串变量进行匹配，然后从那里继续。

public void onBindViewHolder(final ViewHolder holder, final int position) {
        YelpAPI.businessNumber = position;
        YelpAPI.queryAPI(YelpAPI.yelpApi, YelpAPI.yelpApiCli);

    Picasso.with(mContext).load(YelpAPI.picture).into(holder.yelpPicture);
    holder.textName.setText(YelpAPI.name);
    holder.textRating.setText(YelpAPI.rating);
    holder.textReviews.setText(YelpAPI.reviews);
    holder.textAddressDetails.setText(YelpAPI.fullAddress);
    holder.textInfo.setText(YelpAPI.moreInfo);
    holder.textID.setText(YelpAPI.businessID);

----------首先......

    if(position == 0){
        firstBusiness = YelpAPI.businessID; //these three String variables get created above
    } else if(position == 1){
        secondBusiness = YelpAPI.businessID;
    } else if (position == 2) {
        thirdBusiness = YelpAPI.businessID;
    }

    holder.business.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

----------其次...

            int specific = holder.getPosition();

----------最后...

            String saveMe = "";
            if(specific == 0){
                saveMe = firstBusiness;
            } else if(specific == 1){
                saveMe = secondBusiness;
            } else if(specific == 2){
                saveMe = thirdBusiness;
            }
            Log.d("Clicked this item: ", String.valueOf(specific));`
