setvisibility android上的应用程序崩溃

Question

I'm a new developer and I'm encountering a problem when setting the visibility of a layout that covers my UI to disable it while running a script.

Here's my code:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.

    switch (item.getItemId()) {
        case R.id.action_settings:
            return true;

        case R.id.action_loadfile:
            saveTellNamesArray();
            LoadFile(txtFolder, ScriptArray);
            return true;

        case R.id.action_runscript:

            disableLayout();

            stopScript = false;

            scriptThread = new Thread(new Runnable() {
                @Override
                public void run() {
                    while (!scriptThread.isInterrupted() && !stopScript) {
                        runScript();
                    }
                    if (stopScript)//revisar
                        enableLayout();
                }
            });
            scriptThread.start();

            //enableLayout();
            return true;

        case R.id.action_stopscript:
            if (scriptThread != null) {
                //scriptThread.interrupt();
                stopScript = true;
            }
            return true;

        default:
            return super.onOptionsItemSelected(item);
    }
}

The problem is that the app crashes as soon as i call the enableLayout() function:

public void disableLayout() {
    uiBlockLayout.setVisibility(FrameLayout.VISIBLE);
    uiBlockLayout.bringToFront();
}

public void enableLayout() {
    uiBlockLayout.setVisibility(FrameLayout.GONE);
}

Any clues on what the problem might be?

Yes, Issue is occurring accessing UI elements from non UI Thread (calling enableLayout method scriptThread Thread run method).

Use runOnUiThread method for accessing Views from non Ui Thread:

if (stopScript){
   runOnUiThread(new Runnable() {
     @Override
     public void run() {
        enableLayout();
    }
  });
}
