我以前可以使用此代码，但现在由于某些奇怪的原因无法使用。
日期和时间选择器代码
btnDatePicker=(Button)view.findViewById(R.id.btn_date);
btnTimePicker=(Button)view.findViewById(R.id.btn_time);
txtDate=(EditText)view.findViewById(R.id.in_date);
txtTime=(EditText)view.findViewById(R.id.in_time);
btnDatePicker.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(getContext(),
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
txtDate.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);
}
}, mYear, mMonth, mDay);
datePickerDialog.show();
}
});
btnTimePicker.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Get Current Time
final Calendar c = Calendar.getInstance();
mHour = c.get(Calendar.HOUR_OF_DAY);
mMinute = c.get(Calendar.MINUTE);
// Launch Time Picker Dialog
TimePickerDialog timePickerDialog = new TimePickerDialog(getContext(),
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay,
int minute) {
txtTime.setText(hourOfDay + ":" + minute);
}
}, mHour, mMinute, false);
timePickerDialog.show();
}
});

我不太确定如何修复它，它之前工作得很好，但我不知道发生了什么。我刚刚更新了 android studio，然后我的代码中的所有内容都停止工作，我尝试过清理/重建和重新同步，但仍然没有任何结果。
最佳答案
我解决了我的问题。
问题位于我的 styles.xml 文件中。我正在尝试更改应用程序的颜色，但是通过向主题添加颜色强调导致一切都崩溃了。不太清楚为什么。如果有人能解释为什么添加颜色强调会导致这样的问题，那就太好了。
