Drehen Frame-Layout, die dynamischen Tasten

Question

enthält Ich habe einen Framelayout, die in der Mitte und vier Imageview zur Laufzeit hinzufügen, enthält es Haupt-Bild, mit dem Benutzer andere Aktion durchführen kann, aber ich vor dem Problem mit drehen Layout-Ansicht

aktuell Hauch von drehen Taste mache ich das

public void setRotateListener() { 
    mRotateImage.setOnTouchListener(new OnTouchListener() { 
     @Override 
     public boolean onTouch(View v, MotionEvent event) { 
      float x = event.getX(0); 
      float y = event.getY(0); 
      float theta = getTheta(x, y); 

      switch (event.getAction() & MotionEvent.ACTION_MASK) { 
      case MotionEvent.ACTION_POINTER_DOWN: 
       theta_old = theta; 
       break; 
      case MotionEvent.ACTION_MOVE: 
       float delta_theta = theta - theta_old; 
       theta_old = theta; 
       int direction = (delta_theta > 0) ? 1 : -1; 
       angle += 3 * direction; 

       Log.d("Tag", "rotate angle : " + obj.getHeight()); 
       obj.setRotation(angle); 
       notifyListener(direction); 
       break; 
      } 
      return true; 
     } 
    }); 
} 

private float getTheta(float x, float y) { 
    float sx = x - (obj.getWidth()/2.0f); 
    float sy = y - (obj.getHeight()/2.0f); 

    float length = (float) Math.sqrt(sx * sx + sy * sy); 
    float nx = sx/length; 
    float ny = sy/length; 
    float theta = (float) Math.atan2(ny, nx); 

    final float rad2deg = (float) (180.0/Math.PI); 
    float thetaDeg = theta * rad2deg; 

    return (thetaDeg < 0) ? thetaDeg + 360.0f : thetaDeg; 
} 

, aber ich kann nicht das erwartete Ergebnis bekomme ich bereits auf diesen Link finden sie auch https://github.com/rprouse/XkcdClock sowie versuchen, mit Gestik und Animation zu drehen, aber es scheint nicht Arbeiten nach meiner Bewegung auf dem Bildschirm

Ich habe Design Ein Layout, das nach Bedarf funktionieren kann. Demo Download here
