我已在下面附上我的代码。我希望在编辑文本的触摸事件事件中获得日期选择器的对话。我没有得到任何错误但也没有得到任何日期对话。
请帮助我，我错了。提前完成。
String TAG = "AdvancedSearchActivity";
EditText txtArrCity, txtDepCity, txtDate, txtTime;
public String year, month, day;
public static final int DATE_DIALOG_ID = 1;
// OnDateSetListener dateListener;
String DATE;
/*

* @see android.app.Activity#onCreate(android.os.Bundle)
*/
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.advance_search);
txtArrCity = (EditText) findViewById(R.id.edittxt_ArrCity);
txtDepCity = (EditText) findViewById(R.id.edittxt_DepCity);
txtDate = (EditText) findViewById(R.id.edittxt_Date);
txtTime = (EditText) findViewById(R.id.edittxt_Time);
Calendar cal = Calendar.getInstance();

Log.i(TAG, "Year" + year);
Log.i(TAG, "month" + (month + 1));
Log.i(TAG, "Day" + day);
updateDate();
txtDate.setOnTouchListener(new OnTouchListener() {

Log.i(TAG, "Inside On touch");
return false;
}
});
}
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(TabSample.tabcontext,
dateListener, Integer.parseInt(year),
Integer.parseInt(month), Integer.parseInt(day));
}
return null;
}
// the callback received when the user "sets" the date in the dialog

}
};

if ((Integer.parseInt(month)) < 10) {

txtDate.setText(DATE);
}

试试这个
public class name extends Activity {
private EditText dob;

@Override
protected Dialog onCreateDialog(int id) {
Calendar c = Calendar.getInstance();
int cyear = c.get(Calendar.YEAR);
int cmonth = c.get(Calendar.MONTH);
int cday = c.get(Calendar.DAY_OF_MONTH);
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this, mDateSetListener, cyear, cmonth, cday);
}
return null;
}
private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
// onDateSet method
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
String date_selected = String.valueOf(dayOfMonth)+" /"+String.valueOf(monthOfYear+1)+" /"+String.valueOf(year);
//Toast.makeText(getApplicationContext(), "Selected Date is ="+date_selected, Toast.LENGTH_SHORT).show();
dob.setText(date_selected);
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.bankregform);

/* For DOB EditText*/
dob.setOnTouchListener(new OnTouchListener(){
public boolean onTouch(View v, MotionEvent event) {
if(v == dob)
showDialog(DATE_DIALOG_ID);
return false;
}
});
}
