我的datePickerDialog存在问题。使用EditText
作为选择器,当我尝试单击/双击选择器时,它会给我错误。如何防止此错误

我已经尝试在代码上添加datePickerDialog1.isAdded()
,但它仍无效
这是我在datePickerDialog
下面的代码date1 = (EditText) findViewById(R.id.date1);
date2 = (EditText) findViewById(R.id.date2);
datePickerDialog1 = com.fourmob.datetimepicker.date.DatePickerDialog.newInstance(this, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
datePickerDialog2 = com.fourmob.datetimepicker.date.DatePickerDialog.newInstance(this, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
date1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
datePickerDialog1.setYearRange(1910, 2037);
datePickerDialog1.show(getSupportFragmentManager(), DATE_PICKER_1);
datePickerDialog1.setOnDateSetListener(new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePickerDialog datePickerDialog, int year, int month, int day) {
date1.setText(" " + month + " " + day + " " + year);
}
});
}
});
date2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
datePickerDialog2.setYearRange(1910, 2037);
datePickerDialog2.show(getSupportFragmentManager(), DATE_PICKER_2);
datePickerDialog2.setOnDateSetListener(new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePickerDialog datePickerDialog, int year, int month, int day) {
date2.setText(" " + month + " " + day + " " + year);
}
});
}
});
if(savedInstanceState != null) {
DatePickerDialog datePickerDialog1= (DatePickerDialog) getSupportFragmentManager().findFragmentByTag(DATE_PICKER_1);
if(datePickerDialog1!= null || datePickerDialog1.isAdded()) {
datePickerDialog1.setOnDateSetListener(this);
}
DatePickerDialog datePickerDialog2 = (DatePickerDialog) getSupportFragmentManager().findFragmentByTag(DATE_PICKER_2);
if(datePickerDialog2 != null || datePickerDialog2.isAdded()) {
datePickerDialog2 .setOnDateSetListener(this);
}
}
答案 0 :(得分:1)
DatePickerDialog datePickerDialog1;
DatePickerDialog datePickerDialog2;
然后
date1 = (EditText) findViewById(R.id.date1);
date2 = (EditText) findViewById(R.id.date2);
datePickerDialog1 = com.fourmob.datetimepicker.date.DatePickerDialog.newInstance(this, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
datePickerDialog2 = com.fourmob.datetimepicker.date.DatePickerDialog.newInstance(this, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
date1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
datePickerDialog1.setYearRange(1910, 2037);
datePickerDialog1.show(getSupportFragmentManager(), DATE_PICKER_1);
datePickerDialog1.setOnDateSetListener(new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePickerDialog datePickerDialog, int year, int month, int day) {
date1.setText(" " + month + " " + day + " " + year);
}
});
}
});
date2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
datePickerDialog2.setYearRange(1910, 2037);
datePickerDialog2.show(getSupportFragmentManager(), DATE_PICKER_2);
datePickerDialog2.setOnDateSetListener(new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePickerDialog datePickerDialog, int year, int month, int day) {
date2.setText(" " + month + " " + day + " " + year);
}
});
}
});
if(savedInstanceState != null) {
if(datePickerDialog1!= null || datePickerDialog1.isAdded()) {
datePickerDialog1.setOnDateSetListener(this);
}
if(datePickerDialog2 != null || datePickerDialog2 .isAdded()) {
datePickerDialog2 .setOnDateSetListener(this);
}
}
