内部OnClick

Question

我根据列表的大小动态扩充布局。现在每当我点击动态视图时，我必须获得点击子视图的位置。我正在尝试这段代码，但运气不好......

    LinearLayout layoutViewDealsList = (LinearLayout) view.findViewById(R.id.baseLinearLayoutSiteHistory);
    txtViewNoDeals = (TextView) view.findViewById(R.id.txtViewNoDeals);

    if(dealsList != null && dealsList.size() > 0) {
        for(int index = 0; index < dealsList.size(); index++) {
            txtViewNoDeals.setVisibility(View.GONE);
            LayoutInflater inflater = (LayoutInflater) profileActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            layoutView = inflater.inflate(R.layout.deal_row, null);

            txtViewDealsPrice = (TextView) layoutView.findViewById(R.id.txtViewDealPrice);  
            txtViewDealsTitle = (TextView) layoutView.findViewById(R.id.txtViewDealTitle);
            txtViewDealsDescription = (TextView) layoutView.findViewById(R.id.txtViewDealDescription);
            txtViewDealsBuyer = (TextView) layoutView.findViewById(R.id.txtViewDealBuyer);
            txtViewDealsDate = (TextView) layoutView.findViewById(R.id.txtViewDealDate);

            txtViewDealsPrice.setText("Price: $" + dealsList.get(index).getDeal_amount());
            txtViewDealsTitle.setText(dealsList.get(index).getTitle());
            txtViewDealsDescription.setText(dealsList.get(index).getDesc());

            layoutViewDealsList.addView(layoutView);
            int position = layoutViewDealsList.indexOfChild(layoutView);
            layoutViewDealsList.setTag(position);
            appDelegate.setDealsList(dealsList);
        }
    } 


    layoutViewDealsList.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            int position  = (Integer) v.getTag();//layoutViewDealsList.indexOfChild(layoutView);
            Toast.makeText(profileActivity, ""+position, Toast.LENGTH_SHORT).show();


        }
    });

我无法知道我在哪里做错了。

Answer 1

您需要在layoutView内部循环中应用onClickListener。

LinearLayout layoutViewDealsList = (LinearLayout) view.findViewById(R.id.baseLinearLayoutSiteHistory);
txtViewNoDeals = (TextView) view.findViewById(R.id.txtViewNoDeals);

if(dealsList != null && dealsList.size() > 0) {
    for(int index = 0; index < dealsList.size(); index++) {
        txtViewNoDeals.setVisibility(View.GONE);
        LayoutInflater inflater = (LayoutInflater) profileActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        layoutView = inflater.inflate(R.layout.deal_row, null);

    txtViewDealsPrice = (TextView) layoutView.findViewById(R.id.txtViewDealPrice);  
    txtViewDealsTitle = (TextView) layoutView.findViewById(R.id.txtViewDealTitle);
    txtViewDealsDescription = (TextView) layoutView.findViewById(R.id.txtViewDealDescription);
    txtViewDealsBuyer = (TextView) layoutView.findViewById(R.id.txtViewDealBuyer);
    txtViewDealsDate = (TextView) layoutView.findViewById(R.id.txtViewDealDate);

    txtViewDealsPrice.setText("Price: $" + dealsList.get(index).getDeal_amount());
    txtViewDealsTitle.setText(dealsList.get(index).getTitle());
    txtViewDealsDescription.setText(dealsList.get(index).getDesc());

    layoutViewDealsList.addView(layoutView);
    int position = layoutViewDealsList.indexOfChild(layoutView);
    layoutViewDealsList.setTag(position);
    appDelegate.setDealsList(dealsList);

layoutView.setOnClickListener(this); <--------------- setOnClickListener
}

}

你的onClick()看起来像..

@Override
        public void onClick(View v) {

            int position  = (Integer) v.getTag();
            Toast.makeText(profileActivity, ""+position, Toast.LENGTH_SHORT).show();


        }

Answer 2

您需要为每个膨胀的视图设置“OnClickListener”。

OnClickListener onClickListener=new OnClickListener() {

    @Override
    public void onClick(View v) {

        int position  = (Integer) v.getTag();//layoutViewDealsList.indexOfChild(layoutView);
        Toast.makeText(profileActivity, ""+position, Toast.LENGTH_SHORT).show();


    }
};
LinearLayout layoutViewDealsList = (LinearLayout) view.findViewById(R.id.baseLinearLayoutSiteHistory);
txtViewNoDeals = (TextView) view.findViewById(R.id.txtViewNoDeals);

if(dealsList != null && dealsList.size() > 0) {
    for(int index = 0; index < dealsList.size(); index++) {
        txtViewNoDeals.setVisibility(View.GONE);
        LayoutInflater inflater = (LayoutInflater) profileActivity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        layoutView = inflater.inflate(R.layout.deal_row, null);

        txtViewDealsPrice = (TextView) layoutView.findViewById(R.id.txtViewDealPrice);  
        txtViewDealsTitle = (TextView) layoutView.findViewById(R.id.txtViewDealTitle);
        txtViewDealsDescription = (TextView) layoutView.findViewById(R.id.txtViewDealDescription);
        txtViewDealsBuyer = (TextView) layoutView.findViewById(R.id.txtViewDealBuyer);
        txtViewDealsDate = (TextView) layoutView.findViewById(R.id.txtViewDealDate);

        txtViewDealsPrice.setText("Price: $" + dealsList.get(index).getDeal_amount());
        txtViewDealsTitle.setText(dealsList.get(index).getTitle());
        txtViewDealsDescription.setText(dealsList.get(index).getDesc());
        layoutViewDealsList.addView(layoutView);
        int position = layoutViewDealsList.indexOfChild(layoutView);
        appDelegate.setDealsList(dealsList);

        layoutView.setTag(position);
        layoutView.setOnClickListener(onClickListener);
    }
}

另请注意，位置设置为每个布局视图而不是父级。

Answer 3

在设置标记后，只需将点击侦听器放入视图中你完成的所有事情@Avinash kumar Pankaj是对的。

Answer 4

如果有更好的解决方案：

首先设置标记 -

int position = layout.indexOfChild(view);

layout.setTag（位置）;

点击时间：

        @Override
        public void onClick(View v) {
           int position = (Integer) v.getTag();
            fileDataList.remove(position);
            ((LinearLayout) addView.getParent()).removeView(addView);
        }
    });

内部OnClick

CharSequence数据=（（TextView）v）.getText（）;
字符串结果= data.toString（）

单击后获取动态创建的子视图的位置
