So appwidget is fixed after some help on here but before any message has been sent or received the intent to launch the ChatRoomActivity doesn't work.
How could I set it up so it's intent launches the activity before any message has been sent/received(obviously it would have no message but it has a textView saying click to open chat..etc).
my code:
public class ProTalkWidget extends AppWidgetProvider {
private static final String ACTION_BROADCASTWIIDGET = "ACTION_BROADCASTWIIDGET";
public static final String PROTALK_APPWIDGET_UPDATE = "PROTALK_APPWIDGET_UPDATE";
private final int REQUEST_CODE = 0;
public static final String USER_ID = "userId";
DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
FirebaseAuth mAuth = FirebaseAuth.getInstance();
String msgReceiverId;
private void updateAppWidget(Context context, AppWidgetManager appWidgetManager,
final int appWidgetId) {
//Construct the RemoteViews object
final RemoteViews views;
views = new RemoteViews(context.getPackageName(), R.layout.pro_talk_widget);
Intent intent = new Intent(context, ProTalkWidget.class);
intent.setAction(ACTION_BROADCASTWIIDGET);
context.sendBroadcast(intent);
appWidgetManager = AppWidgetManager.getInstance(context);
appWidgetManager.updateAppWidget(appWidgetId, views);
}
@Override
public void onReceive(Context context, Intent intent) {
super.onReceive(context, intent);
if(PROTALK_APPWIDGET_UPDATE.equals(intent.getAction())){
Log.i("onReceive", "getting onReceived!");
handleMsg(intent, context);
}
}
private void handleMsg(final Intent intent, final Context ctx){
msgReceiverId = intent.getStringExtra("receiverId");
if(msgReceiverId!=null) {
String my_Id = mAuth.getCurrentUser().getUid();
final RemoteViews views;
views = new RemoteViews(ctx.getPackageName(), R.layout.pro_talk_widget);
DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
Query query = rootRef.child("Messages").child(my_Id).child(msgReceiverId).limitToLast(1);
ValueEventListener valueEventListener = new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
for(DataSnapshot ds : dataSnapshot.getChildren()) {
Messages messages = ds.getValue(Messages.class);
String message = messages.getMessage();
String from = messages.getFrom();
Log.d("TAG", message + "+" + from);
views.setTextViewText(R.id.appwidget_message, message);
Intent mainIntent = new Intent(ctx, ChatRoomActivity.class);
if(msgReceiverId != null)
mainIntent.putExtra("profile_view_userId", msgReceiverId);
mainIntent.putExtra("username", "Ben");
PendingIntent mainPendingIntent = PendingIntent.getActivity(ctx, REQUEST_CODE, mainIntent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.widget_layout, mainPendingIntent);
AppWidgetManager.getInstance(ctx).updateAppWidget(new ComponentName(ctx, ProTalkWidget.class), views);
}
}
@Override
public void onCancelled(DatabaseError databaseError) {}
};
query.addListenerForSingleValueEvent(valueEventListener);
}
}
@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
// There may be multiple widgets active, so update all of them
for (int appWidgetId : appWidgetIds) {
updateAppWidget(context, appWidgetManager, appWidgetId);
}
super.onUpdate(context, appWidgetManager, appWidgetIds);
}
@Override
public void onEnabled(Context context) {
// Enter relevant functionality for when the first widget is created
}
@Override
public void onDisabled(Context context) {
// Enter relevant functionality for when the last widget is disabled
}
}
Please note intent and displaying message works after chatroomactivity has been opened and message sent.
