在android中，如何在多文本视图上手动收缩放大和缩小？

如何在framelayout中的多个文本视图上手动拖放？
我已经添加了两个textview，我想在单个textview上同时拖放功能

我在framelayout中添加了TextView。这是我的密码：

 public class MainActivity extends AppCompatActivity {

//private ImageView imageView;
private TextView textView,textView1;
private ScaleGestureDetector scaleGestureDetector;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    textView = (TextView) findViewById(R.id.text_view);
    textView1 = (TextView) findViewById(R.id.text_view1);
  //  imageView = (ImageView) findViewById(R.id.ImageView01);
    scaleGestureDetector = new ScaleGestureDetector(this, new simpleOnScaleGestureListener());

    textView.setOnTouchListener(new View.OnTouchListener() {
        private int deltaX;
        private int deltaY;
        private float initialTouchX;
        private float initialTouchY;
        private boolean isMoved;
        private int lastTouchX;
        private int lastTouchY;

        @Override
        public boolean onTouch(final View v, final MotionEvent event) {

            ViewGroup vg = (ViewGroup) v.getParent();

            int draggedViewIndex = vg.indexOfChild(v);
            initialTouchX = event.getRawX();
            initialTouchY = event.getRawY();
            boolean result = v.onTouchEvent(event);
            switch (event.getAction()) {
                case MotionEvent.ACTION_DOWN: {
                    isMoved = false;
                    FrameLayout.LayoutParams params = (FrameLayout.LayoutParams) v
                            .getLayoutParams();

                    deltaX = (int) initialTouchX - params.leftMargin;
                    deltaY = (int) initialTouchY - params.topMargin;

                    lastTouchX = (int) initialTouchX;
                    lastTouchY = (int) initialTouchY;
                    Log.e("ashish", "ACTION_DOWN lasttouchX: " + lastTouchX);
                    Log.e("ashiosh", "ACTION_DOWN lasttouchY: " + lastTouchY);
                    new Handler().postDelayed(new Runnable() {

两者都是int变量
