我正在尝试将日期选择器添加到我的代码中，但是在“ fromDate_textView.setOnClickListener”内的“ pickerListener”上显示错误：
pickerListener无法解析为变量
谁能帮我解决问题？
fromDate_textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
showDialog(DatePickerDialog(Sell_Product_Activity.this,
pickerListener, year, month, day));
}
});
DatePickerDialog.OnDateSetListener pickerListener = new DatePickerDialog.OnDateSetListener() {
// when dialog box is closed, below method will be called.
@Override
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
year = selectedYear;
month = selectedMonth;
day = selectedDay;
// Show selected date
fromDate_textView.setText(new StringBuilder().append(month + 1)
.append("-").append(day).append("-").append(year)
.append(" "));
}
};
最佳答案
使用此代码可以解决您的问题，可以正常工作
// for date picker
private int year;
private int month;
private int day;
static final int DATE_PICKER_ID = 1111;
// for date picker
private EditText m3_DateDisplay;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
m3_DateDisplay = (EditText) findViewById(R.id.editText3);
// Get current date by calender
final Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
// Show current date
/*m3_DateDisplay.setText(new StringBuilder()
// Month is 0 based, just add 1
.append(day).append("-").append(month + 1).append("-")
.append(year).append(" "));*/
// Show selected date
StringBuilder dateValue1=new StringBuilder().append(day).append("-")
.append(month + 1).append("-").append(year).append(" ");
//for Converting Correct Date format Save into Database
SimpleDateFormat sdf123 = new SimpleDateFormat("dd-MM-yyyy");
String abs1= dateValue1.toString();
Date testDate1 = null;
try {
testDate1 = sdf123.parse(abs1);
} catch (ParseException e) {
e.printStackTrace();
}
SimpleDateFormat formatter1 = new SimpleDateFormat("dd-MM-yyyy");
String DateFormat=formatter1.format(testDate1);
m3_DateDisplay.setText(DateFormat);
m3_DateDisplay.setFocusable(false);
m3_DateDisplay.setInputType(InputType.TYPE_NULL);
m3_DateDisplay.setOnClickListener(new View.OnClickListener() {
