Android getting EditText content from a while loop in seperate method

[Michael Swann]

In my problem, I have my MainActivity, with a TextView and EditText, and a Thread, excecuting a method, which should send out messages to the TextView and receive the content of an EditText. The problem is receiving text from the EditText, since it throws the exception:

android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

I have looked at the possibilities of runAsUiThread() and Handler, but i haven't found a solution to pass the content of the EditText yet.

Have I overseen a possibility with the Handler to pass content back, or is there some other solution here?

I'll try to post my cropped code so you will gain some knowledge about what I am trying to achieve.

public class MainActivity extends Activity {

public class MonitorObject{
}
final MonitorObject mSync = new MonitorObject();
private TextView mConsoleOut;
private EditText mInputLine;
public String inputString;
public synchronized String getInputString(String value){this.inputString = value; return inputString;}

IOHandler IOhandler;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mConsoleOut = (TextView) findViewById(R.id.consoleOut);
    mInputLine = (EditText) findViewById(R.id.actionInField);


    EditText editText = (EditText) findViewById(R.id.actionInField);
    editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            /*boolean handled = false;
            if (actionId == EditorInfo.IME_ACTION_DONE) {
                Item.Weapon.Rock rock = new Item.Weapon.Rock();
                mConsoleOut.setText(rock.str());
                handled = true;
            }
            return handled;*/
            synchronized (mSync){
                mSync.notify();
            }
            return true;
        }
    });
    GameCycle gameCycle = new GameCycle();
    Thread gameloop = new Thread(gameCycle);
    gameloop.start();
}

public class GameCycle implements Runnable{
    public void run(){
        game();
    }
}

public void game(){
    //final TextView mConsoleOut = (TextView) findViewById(R.id.consoleOut);
    //final EditText mInputLine = (EditText) findViewById(R.id.actionInField);
    Integer time=0;
    PlayerClass p1 = new PlayerClass(1,4);
    TileClass tile = new TileClass.Forest();
    Integer gamestate=0;


    while(gamestate==0){
        time++;
        tile.initialize_tilesettings(time, p1);
        tile.passed=true;
        List actionResponse=new ArrayList(Arrays.asList("repeat", "type", "returnval"));

        while(gamestate==0 && !actionResponse.get(1).equals("tileChange")){

            actionResponse=Arrays.asList("repeat", "type", "returnval");
            Boolean tileActions = true;

            while(!actionResponse.get(0).equals("continue")){
                //actions to be repeated

                String exe=null;

                tileActions=true;

                List<String> params = new ArrayList<>();

                <<<<<print>>>>>("\nWhat will you do?");

                synchronized (mSync){
                    try {
                        mSync.wait();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }

                <<<<<getinput>>>>>String inp=returnInputString();
                String[] splitIn=inp.split(" ");


                for(String text:splitIn){
                    params.add(text.toLowerCase());
                }

                for(ActionClass action:p1.getActions()){
                    if(action.method.contains(params.get(0))){
                        exe=action.method;
                    }
                }

                if(exe==null){
                    <<<<<print>>>>>("Not a valid action");

                    actionResponse=Arrays.asList("repeat","","");
                }
                else{
                    try{
                        actionResponse=p1.excecFunctionByTag(exe, Arrays.asList(p1, tile, params));
                        if(actionResponse==null){
                            throw new RuntimeException();
                        }
                    }
                    catch (Exception e){

                        }
                    }
                    return;
                }


            }

Any help is greatly appreciated.
