Question

我有一个物品清单。我正在使用for循环按照列表的大小创建动态按钮。

我在循环的第一项时显示一些数据。现在/我想在单击按钮时切换数据。

按钮将包含项目的编号，如果列表中有三个项目，则有三个按钮名为一，二，三。

因此，如果我先点击，我想显示第一项的数据，如果分别是第二项的第二项数据。

我试图这样做，但我无法得到结果。

 @Override
public void doPostExecute(List<Payment> list1)
{

    list.addAll(list1);

    for(final Payment payment : list) {

        i++;

        Button myButton = new Button(getActivity());

        LinearLayoutCompat.LayoutParams lp = new LinearLayoutCompat.LayoutParams(60,30);
        linear_buttons.addView(myButton, lp);

        myButton.setText(String.valueOf(i));
        myButton.setBackgroundResource(R.drawable.edit_button);

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

                if (payment.getPaidAmount() != null && !payment.getPaidAmount().equals("null"))
                    txt_paid.setText("$" + payment.getPaidAmount());

                if (payment.getProductStatus() != null && !payment.getProductStatus().equals("null")) {
                    if (payment.getProductStatus().equals("1")) {
                        txt_status.setText(getString(R.string.paid));

                }
            }
        }

    }

}

我怎样才能做到这一点？请帮忙..谢谢。

Answer 1

您正在使用变量i作为全局变量并在循环内使用i++。因此，在onClick方法中，if(i == 1)始终为false，或始终为true。

将变量设为本地，并在创建按钮的for循环中使用myButton.setId(i);。

现在在OnClickListener内，您可以使用int id = v.getId();并使用if(id == 1)

Answer 2

您可以将onClickLister设置为该行中的按钮，该按钮将引用该行的数据。使用意图开始详细活动，并将点击的项目数据作为额外内容添加。

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

//Inflate your row

button.setOnClickListener(new OnClickListener(){
    @Override
    //On click function
    public void onClick(View view) {
         HashMap<String, String> item = contactsList.get(position);
         //Create the intent to start another activity
         Intent intent = new Intent(view.getContext(), DetailActivity.class);
         intent.putExtra("data", item);
         view.getContext().startActivity(intent);
    }
});
});

在接收活动中，您可以从意图中获取数据

HashMap<String, String> data = getIntent().getExtras().getParcelableExtra("data");

如何切换onClick按钮的数据？
