runOnUiThread from class that doesn't support it

I am editing this code from cSipSimple: https://code.google.com/p/csipsimple/source/browse/trunk/CSipSimple/src/com/csipsimple/ui/incall/InCallCard.java?spec=svn2170&r=2170

And wish to add this method:

public void pushtotalk2(final View view) {

        final boolean on = ((ToggleButton) view).isChecked();
        ((ToggleButton) view).setEnabled(false);

        new Thread(new Runnable() {
            @Override


    public void run() {
            try {
                Instrumentation inst = new Instrumentation();
                if (on) {

                    inst.sendKeyDownUpSync(KeyEvent.KEYCODE_NUMPAD_MULTIPLY);
                    Thread.sleep(500);
                    inst.sendKeyDownUpSync(KeyEvent.KEYCODE_9);
                    Thread.sleep(500);

                    runOnUiThread(new Runnable() {
                        public void run() {
                            ((ToggleButton) view).setBackgroundResource(R.drawable.btn_blue_glossy);
                            ((ToggleButton) view).setEnabled(true);
                        }
                    });
                } else {
                    inst.sendKeyDownUpSync(KeyEvent.KEYCODE_POUND);
                    Thread.sleep(500);
                    inst.sendKeyDownUpSync(KeyEvent.KEYCODE_9);
                    Thread.sleep(500);
                    runOnUiThread(new Runnable() {
                        public void run() {
                            ((ToggleButton) view).setBackgroundResource(R.drawable.btn_lightblue_glossy);
                            ((ToggleButton) view).setEnabled(true);
                        }
                    });
                }
            } catch (InterruptedException e) {
                Log.d(TAG, "Failed to send keycodes: " + e.getMessage());
            }
        }
    }).start();
}

However I get the error: runOnUiThread(new Runnable(){}) is undefined for the type new Thread(){}

My understanding is that the activity class has this method, but how do I access it from my code?

I tried making a constructor and got this error:

Implicit super constructor FrameLayout() is undefined. Must explicitly invoke another constructor

Any ideas on how this is done correctly?

runOnUiThread is not defined for Views. Only for Activities. And InCallCard is just a view.

You can use the post(Runnable) method instead of runOnUiThread().

Since you want to run something in the UI Thread from a non Activity class, you can use a Handler instead. 

new Handler().post(new Runnable() {
     public void run() {
         ((ToggleButton) view).setBackgroundResource(R.drawable.btn_blue_glossy);
         ((ToggleButton) view).setEnabled(true);
     }
});
