我有一个活动 1,它将意图发送到活动 2,如下所示:
活动一
periodDatetv.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(Settings.this, SettingsPeriodDate.class);
startActivityForResult(i, 100);
}
});
活动二
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
todayCalendar = new GregorianCalendar();
pickedDateCalendar = new GregorianCalendar();
final Dialog dialog = new Dialog(SettingsPeriodDate.this);
dialog.setContentView(R.layout.perioddatesettings);
datePicker = (DatePicker) dialog.findViewById(R.id.DataPickerDate);
dialog.show();
Button okDialogButton = (Button) dialog
.findViewById(R.id.dialogButtonOK);
// if button is clicked, close the custom dialog
okDialogButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Calendar c = Calendar.getInstance();
int currentYear = c.get(Calendar.YEAR);
int currentMonth = c.get(Calendar.MONTH) + 1;
int currentDay = c.get(Calendar.DAY_OF_MONTH);
Day = datePicker.getDayOfMonth();
Month = datePicker.getMonth() + 1;
Year = datePicker.getYear();
todayCalendar.set(currentYear, currentMonth, currentDay);
pickedDateCalendar.set(Year, Month, Day);
System.err.println("Choseon date = " + Day + "/" + Month + "/"
+ Year);
System.err.println("Today date = " + currentDay + "/"
+ currentMonth + "/" + currentYear);
int Days = daysBetween(todayCalendar.getTime(),
pickedDateCalendar.getTime());
System.err.println("Daaaaays === " + Days);
if (pickedDateCalendar.after(todayCalendar) || Days >= 1) {
System.err.println("Inside if pop it");
PopIt("Error ", "Please check the date again");
}
else {
periodDateSharedPreferences(Year, Month, Day);
}
dialog.dismiss();
System.err.println("befor back");
Intent saved2 = new Intent(SettingsPeriodDate.this,
Settings.class);
startActivityForResult(saved2, 100);
}
});
Button cancelDialogButton = (Button) dialog
.findViewById(R.id.dialogButtonCancel);
// if button is clicked, close the custom dialog
cancelDialogButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
Intent i = new Intent(SettingsPeriodDate.this,Settings.class);
startActivity(i);
}
});
}
public int daysBetween(Date d1, Date d2) {
return (int) ((d2.getTime() - d1.getTime()) / (1000 * 60 * 60 * 24));
}
public void periodDateSharedPreferences(int calculatedPeriodYear,
int calculatedPeriodMonth, int calculatedPeriodDay) {
SharedPreferences periodDatePreferences = PreferenceManager
.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor = periodDatePreferences.edit();
editor.putInt("periodChosenDay", calculatedPeriodDay);
editor.putInt("periodChosenMonth", calculatedPeriodMonth);
editor.putInt("periodChosenYear", calculatedPeriodYear);
editor.commit();
System.err.println("periodChosenDay preferences"
+ periodDatePreferences.getInt("periodChosenDay", 0));
System.err.println("periodChosenMonth preferences"
+ periodDatePreferences.getInt("periodChosenMonth", 0));
System.err.println("periodChosenYear preferences"
+ periodDatePreferences.getInt("periodChosenYear", 0));
Toast.makeText(SettingsPeriodDate.this, "The date was saved",
Toast.LENGTH_LONG).show();
finish();
}
public void PopIt(String title, String message) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Error");
builder.setMessage("Please check again");
builder.setCancelable(true);
final AlertDialog dlg = builder.create();
dlg.show();
final Timer t = new Timer();
t.schedule(new TimerTask() {
public void run() {
dlg.dismiss();
t.cancel();
}
}, 100000);
}
我在活动 1中得到如下结果:
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 100:
System.err.println("after intent back 111111=== ");
if (resultCode == Activity.RESULT_OK) {
System.err.println("after intent back if=== ");
int day = data.getIntExtra("Day", 0);
int month = data.getIntExtra("Month", 0);
int year = data.getIntExtra("Year", 0);
System.err.println("after intent back =///== " + day + "-" + month
+ "-" + year);
Toast.makeText(Settings.this,day+"?"+month+"?"+year,Toast.LENGTH_SHORT).show();
periodDatetv.setText(day + "/" + month + "/" + year);
break;
}
}
}
但它从不运行 onActivityResult 方法!我的代码有什么问题?请告诉我..提前谢谢
