在DatePicker上双击时应用程序崩溃

Question

自定义datePicker代码：

package com.example.logindesign;
import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.ViewParent;
import android.widget.CalendarView;


public class CalendarViewScrollable extends CalendarView {
    public CalendarViewScrollable(Context context) {
        super(context);
    }

    public CalendarViewScrollable(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CalendarViewScrollable(Context context, AttributeSet attrs,
            int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev)
    {
        if (ev.getActionMasked() == MotionEvent.ACTION_DOWN)
        {
            ViewParent p = getParent();
            if (p != null)
                p.requestDisallowInterceptTouchEvent(true);
        }

        return false;
    }

}

这就是我如何在我的主要活动中使用这个类：

final TextView dateT=(TextView)findViewById(R.id.TextDate);
    dateT.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v){
            DatePickerDialog datepicker= new DatePickerDialog(MainActivity.this,new DatePickerDialog.OnDateSetListener() {                      
                    @Override
                    public void onDateSet(DatePicker view, int year, int month,
                            int day) {
                        // TO DO Auto-generated method stub 
                        month+=1;   
                        dateT.setText(+year + "  /  " + month + "  /  " + day);
                        jn=day;
                        mn=month;
                        an=year;
                    }
                },1990,1,1);
        datepicker.setTitle("Sélectionner la date de naissance");
        datepicker.updateDate(1990, 1, 1);
        datepicker.show();

        }
    });

Answer 1

这是特定设备的问题

若要记录或提示所选日期，DatePicker使用
