error: Only the original thread that created a view hierarchy can touch its views


android view hierarchy settext

In your run() method:

Message msg = new Message();String textTochange = "text";msg.obj = textTochange;mHandler.sendMessage(msg);

Create the mHandler in your UI thread;

Handler mHandler = new Handler() {        @Override        public void handleMessage(Message msg) {            String text = (String)msg.obj;            //call setText here        }};

android view hierarchy settext

You are not on the UI thread when setting the text. You need to be on UI if you want to work on UI items. Create a message handler on the UI thread, post your messages to it and call setText from the handler on the UI thread.

android view hierarchy settext

you can do this whenever you are in a thread:

msgToServer.post(new Runnable() {    public void run() {        msgToServer.setText("your text here");    }}
