In my android application I have a TextView in a ScrollView.
I want to update TextView dinamically and I write this statement :
mTextView.append(mText); mScrollView.pageScroll(ScrollView.FOCUS_DOWN);
and so my application works. Unfortunately the strings that I have to insert are shown ALL TOGETHER at the end of application.

I have an issue with the following error in Android: CalledFromWrongThreadException;: Only the original thread that created a view hierarchy can touch its views. It appears to happen when I try to update a Textview in my Activity, the call to update the TextView is from within my Activity but I still get the above error. I have it like this:
onCreate()
-sets up the buttons and the text view.
onStateChange() - a listener for notifications about state changes, when this gets notification if changes the TextView to say some different text.............
I receive data from udp server from my application.when i receive data i have to show that on the screen.I just use the Textview to display the incoming data(textview.setText ("data")).But it displays the last incoming data only.I need to show the previous data also.how to solve this? DatagramSocket clientsocket=new DatagramSocket(6363); byte[] receivedata=new byte[1024];while(true)DatagramPacket recv_packet=new DatagramPacket (receivedata, receivedata.length);textview.setText("UDP S: Receiving");clientsocket. receive(recv_packet);String rec_str=new String(recv_packet.getData()); textview.setText (" Received String "+rec_str); when i use append method it display's after all the incoming finished. I need to view when the data is coming at that time i have to show that.

I have an Android activity that, onCreate(), will query a database and display the query results in textviews on the UI.The problem that I am having is at some point, users can open another activity and update the database. When they go back to the original activity, I would like for the text views to update with the new database information (so, I will re query the database and display the info).Another thing that I am willing to do is to take the new input from the user (in the new activity) and directly update the textview in the existing activity (without having the existing activity re-query the database). But I'm not sure how to do something like that either.Can someone please inform me on the best way to go about doing this? The only solution that I have found so far has to do with broadcast receivers, but I'm not sure if that is best suited for what I have to do.
View 2 Replies View RelatedI have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space for text when there isn't any making the entire list have annoying blank gaps. I remember seeing an example of where someone made the layout not reserve the space, but I can't remember how he did it.

I have a TextView that I created in the main.xml. In my app.java I am dynamically positioning that TextView based on where the user taps the screen. The problem I am having is that when I call myTextView.setPadding(100,100,0,0), it moves the actual Text of the TextView, but does not move the Colored Background of the TextView.
