Question

我有3个日期选择器的活动。问题是，在将所需的日期值设置到我的表单并单击后面后，再次显示Datepicker对话框。我点击取消按钮再次点击返回，我有一个FC。来自Logcat：

以下是代码的一部分：

mPickDate = (ImageView) findViewById(R.id.pickDate);
  mPickDate.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
         showDialog(DATE_DIALOG_ID);
        }
    });

@Override
protected Dialog onCreateDialog(int id) {
 switch (id) {
 case DATE_DIALOG_ID:
     return new DatePickerDialog(this,
                 mDateSetListener,
                 mYear, mMonth, mDay);
 case DATE_DIALOG_ID_RETURN:
     return new DatePickerDialog(this,
       mDateSetListenerreturn,
                 mYear, mMonth, mDay);     
 }
 return null;
}

 // updates the date in the TextView
    private void updateDisplay(TextView mDateDisplay) {
    mDateDisplay.setText(
        new StringBuilder()
                // Month is 0 based so add 1
               .append(mDay).append("-")
               .append(mMonth + 1).append("-")
               .append(mYear).append("")


                );
}
private DatePickerDialog.OnDateSetListener mDateSetListener =
    new DatePickerDialog.OnDateSetListener() {

        public void onDateSet(DatePicker view, int year, 
                              int monthOfYear, int dayOfMonth) {
            mYear = year;
            mMonth = monthOfYear;
            mDay = dayOfMonth;
            updateDisplay(mDateDisplay);
        }
    };

我在onCreateDialog（）中使用'getParent（）'更改了'this'，但没有任何反应有什么建议吗？

Answer 1

您的错误发生在DialogManager.java的第63行。在没有看到代码的情况下，我不能再具体了，但看起来你的showDialog()的一个参数存在问题。

您已按照here所述覆盖了onCreateDialog()方法，如果是，则在给定id = 2时创建一个对话框，不是吗？
