我如何在动态布局中打开时间选择器对话框

Question

我有三个编辑文本1）服务2）是收费3）是时间所以我不知道会给美容院提供多少服务。所以我制作了一个动态布局，服务提供商动态地选择了那里的服务。我使用的是两个布局，一个是父布局，第二个是子视图布局..所有工作很好，但是要选择时间。时间选择器对话框仅在父布局中打开。无法在子视图布局中打开。如果有人知道，请帮助我。这是我完整的代码和图片

问题是您仅将View.ClickListener设置为作为EditText time的直接子级的单个视图R.layout.activity_services_and_rate_list。

稍后您将更多的子视图添加到膨胀的R.layout.activity_services_and_rate_list布局中，但未设置点击侦听器。

其中一个选项是创建一个方法，该方法将为每个经过的时间EditText设置点击侦听器。

注：考虑将RecyclerView与适配器一起使用。当布局中的视图数增加时，它的性能会好得多。

public class ServicesAndRateList extends AppCompatActivity {

    //your variables here ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        //your other onCreate code here ...

        setTimeEditTextClickListener(time);
    }

    private void setTimeEditTextClickListener(EditText time) {
        time.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                timePickerDialog = new TimePickerDialog(ServicesAndRateList.this, new TimePickerDialog.OnTimeSetListener() {
                    @Override
                    public void onTimeSet(TimePicker timePicker, int hourOfDay, int minutes) {
                        time.setText(hourOfDay + ":" + minutes);
                    }
                }, 0, 0, true);

                timePickerDialog.show();
            }
        });
    }

    public void onAddField(View view) {
        LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        final View rowView = inflater.inflate(R.layout.childview, null);
        // Add the new row before the add field button.
        parentLinearLayout.addView(rowView, parentLinearLayout.getChildCount() - 1);
        setTimeEditTextClickListener((EditText) rowView.findViewById(R.id.time));
    }
}
