time zone not come in kotlin to java

[rajam1215]

Attempt to cast generated internal exception: java.lang.ClassCastException: java.util.SimpleTimeZone cannot be cast to java.lang.String

this error is coming

because behalf of code timezone come in string. but android studio show timezone not convert in string.

the timezone not come because when i give timezone in intent in java class. that will not taken by kotlin class. behalf your code , u send time zone. in DateTimeRangePicker. but in java class intent working type is different. i think u know.

how can i solve this issue. please give me a solution

Thanks

Did you use newIntent() to launch DateTimeRangePickerActivity? How did you pass the instance of SimpleTimeZone into newIntent()? A code snippet would be very helpful to tackle the issue.

[rajam1215]

Ok, The code is

            Intent intent = new Intent(MainActivity.this, DateTimeRangePickerActivity.class);
            intent.putExtra("",TimeZone.getDefault());
            startActivityForResult(intent, RQC_PICK_DATE_TIME_RANGE);

this is my java code. and i dont know witch way i send(java code) intent data in kotlin class

behalf your code u send data in intent with the syntax of kotlin.

please give me a solution

That's an invalid usage. Pls make sure you always use newIntent() to launch DateTimeRangePickerActivity like described in https://github.com/skedgo/DateTimeRangePicker#usage. If you call it from Java code, make sure you invoke the Companion (e.g. DateTimeRangePickerActivity.Companion.newIntent(...)).

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == RQC_PICK_DATE_TIME_RANGE && resultCode == Activity.RESULT_OK) {
        if (data != null) {
            long start = data.getLongExtra("startTimeInMillis", 0);
            long end = data.getLongExtra("endTimeInMillis", 0);
            String timezone = data.getStringExtra("timeZone");
            Log.e("Time", "Start : " + start + " end : " + end + " time : " + timezone);
        } else {
            Log.e("Time", "not come");
        }
    }
}

and this type i get data from main Activity in java class

thx

The library uses Joda-Time to manipulate some date time logic under the hood. So you might need this https://github.com/dlew/joda-time-android#usage.

Ok

currently i use intent like this

            Intent intent = DateTimeRangePickerActivity.Companion.newIntent(MainActivity.this, TimeZone.getDefault(), null, null);
            startActivityForResult(intent, RQC_PICK_DATE_TIME_RANGE);

OnActivityResult like this

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == RQC_PICK_DATE_TIME_RANGE && resultCode == Activity.RESULT_OK) {
        if (data != null) {
            long start = data.getLongExtra("startTimeInMillis", 0);
            long end = data.getLongExtra("endTimeInMillis", 0);
            String timezone = data.getStringExtra("timeZone");
            Log.e("Time", "Start : " + start + " end : " + end + " time : " + timezone);
        } else {
            Log.e("Time", "not come");
        }
    }
}

and In Application class. i use

public class AppController extends Application {

@Override
public void onCreate() {
    super.onCreate();
    JodaTimeAndroid.init(this);
}

}

but steal this error come

Attempt to cast generated internal exception: java.lang.ClassCastException: libcore.util.ZoneInfo cannot be cast to java.lang.String at android.os.BaseBundle.getString(BaseBundle.java:923)

TimeZone steal null in OnActivityResult

Thanks

Ok, I can recognize the problem now. DateTimeRangePickerViewModel put timeZone into Intent as Serializable instead String. Will deliver the fix.

Fixed by https://github.com/skedgo/DateTimeRangePicker/commit/7194744eb61476cee2aa6e9d568350df14545ea9.
