The activity that i want to open will show to the player his score. the activity is equal to all game modes, there will be some test to the app understant what path should go on. test like this one:
"
if (gameStatus == 12) {
gameScore = gameScore*55;
TextView scoreText = (TextView) findViewById(R.id.textView8);
scoreText.setText(gameScore);
}
else if (gameStatus == 15){
"
There are 4 game modes: This is the 6x4 game, where we can find 24 cards (12 images).
else if (gameStatus == 15){
Intent intent = new Intent(Game6x4Activity.this, NextActivity.class);
startActivity(intent);
}
I think, you are asking for this. You can pass value to another activity with
intent.putExtra("key",desired value);

Try like this :
progressDialog = new ProgressDialog(getActivity());
And if you wish to customize your dialog and put self created Layout in it.
/**

*/
public class CustomDialog {
private static Dialog dialog;
private static Context context;
public CustomDialog(Context context) {
this.context = context;
}
/**

* #param title
*/
public static void showProgressDialog(Context context, String title, String message) {
if (dialog == null)
{
dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.custom_loader);
dialog.setCancelable(false);
dialog.setCanceledOnTouchOutside(false);
dialog.show();
}
}
public static boolean isProgressDialogRunning() {
if (dialog != null && dialog.isShowing()) {
return true;
} else return false;
}
/**

*/
public static void dismissProgressDialog() {
if (dialog != null && dialog.isShowing()) {
dialog.dismiss();
dialog = null;
}
}
} // End of main class over here ...
Replace this:-
progressDialog = new ProgressDialog(getContext(), ProgressDialog.THEME_HOLO_LIGHT);
with
progressDialog = new ProgressDialog(getActivity());
May be. you are showing two progressdialog and both of that progressbar on screen.. but when you dismiss your progressbar at that time the previous one is override by other one before you dismiss first one .. so the firstone is always in screen. that's the issue.
I tried everything.But none of the answers solved the issue.However,i solved it by overriding onResume() method in the fragment.
Thanks All.
I trying to change chatroom.java's createReplayMsg message resource from GCM ,but why apapter.getData().add error?
It tell me java.util.List com.example.yoyotrip.chat.MessageAdapter.getData()' on a null object reference.
maybe I should use AsyncTask to finish it?
PS. I am first use this forum ,other Resources in this-> https://github.com/yyting/yoyotrip or tell me,thanks.

You never use your adapter's constructor to create a new instance in GcmBroadcastReceiver. Your adapter will always be null, hence, NullPointerExceptions on that getData() call.
I need help on how to go about and make prev month's days visible (grayed out) on this calendar.

and this is the Activity code on how i am using this adapter:
CalendarView.java
/*some code above*/
/*this is in the OnCreate block*/
adapter = new CalendarAdapter(this, month);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(adapter);
/*some code below*/
and heres my calendar view screen (grid):
CalendarView Screenshot:
To be straight and to the point,All i want is that blank boxes before 1st of the month be filled in with the previous month's last week's days
Declare another calendar
private java.util.Calendar month, prevMonth;
Add a clone to calendar in the constructor
prevMonth = (Calendar) month.clone();
prevMonth.roll(Calendar.MONTH, false);
Then replace the refreshDays with this one.This fills up the blank spaces with the days from the last month and the next month for the first and last week of the current month respectively.
public void refreshDays() {
// clear items
items.clear();
int lastDay = month.getActualMaximum(Calendar.DAY_OF_MONTH);
int firstDay = (int) month.get(Calendar.DAY_OF_WEEK);
int maxweek = month.getActualMaximum(Calendar.WEEK_OF_MONTH);
Log.d("CalendarAdapter", String.valueOf(maxweek));
