大家好:
想請教MovableFloatingActionButton的問題
需求:
1.希望長按能移動button (完成)
2.希望短按能顯示訊息(努力中....)

想詢問第二個要怎麼做?因為我現在案都顯示不出訊息......
以下是程式碼:
MovableFloatingActionButton.java

public class MovableFloatingActionButton extends FloatingActionButton implements View.OnTouchListener {

    private final static float CLICK_DRAG_TOLERANCE = 10; // Often, there will be a slight, unintentional, drag when the user taps the FAB, so we need to account for this.
    private float downRawX, downRawY;
    private float dX, dY;

    public MovableFloatingActionButton(Context context) {
        super(context);
        init();
    }

    public MovableFloatingActionButton(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public MovableFloatingActionButton(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    private void init() {
        setOnTouchListener(this);
    }

    @Override
    public boolean onTouch(View view, MotionEvent motionEvent){

        int action = motionEvent.getAction();
        if (action == MotionEvent.ACTION_DOWN) {

            downRawX = motionEvent.getRawX();
            downRawY = motionEvent.getRawY();
            dX = view.getX() - downRawX;
            dY = view.getY() - downRawY;

            return true; // Consumed

        }
        else if (action == MotionEvent.ACTION_MOVE) {
            int viewWidth = view.getWidth();
            int viewHeight = view.getHeight();

            View viewParent = (View)view.getParent();
            int parentWidth = viewParent.getWidth();
            int parentHeight = viewParent.getHeight();

            float newX = motionEvent.getRawX() + dX;
            newX = Math.max(0, newX); // Don't allow the FAB past the left hand side of the parent
            newX = Math.min(parentWidth - viewWidth, newX); // Don't allow the FAB past the right hand side of the parent

            float newY = motionEvent.getRawY() + dY;
            newY = Math.max(0, newY); // Don't allow the FAB past the top of the parent
            newY = Math.min(parentHeight - viewHeight, newY); // Don't allow the FAB past the bottom of the parent

            view.animate()
                    .x(newX)
                    .y(newY)
                    .setDuration(0)
                    .start();

            return true; // Consumed

        }
        else if (action == MotionEvent.ACTION_UP) {

            float upRawX = motionEvent.getRawX();
            float upRawY = motionEvent.getRawY();

            float upDX = upRawX - downRawX;
            float upDY = upRawY - downRawY;

            if (Math.abs(upDX) < CLICK_DRAG_TOLERANCE && Math.abs(upDY) < CLICK_DRAG_TOLERANCE) { // A click
                return performClick();
            }
            else { // A drag
                return true; // Consumed
            }
        }
        else {
            return super.onTouchEvent(motionEvent);
        }

    }

}

Main.java:

   fab=(MovableFloatingActionButton)findViewById(R.id.fab);
     
      fab.setOnClickListener(btnclick);
    
    private MovableFloatingActionButton.OnClickListener btnclick=new MovableFloatingActionButton.OnClickListener(){
        @Override
        public void onClick(View view) {
           mytoast("show message");//如果user沒移動button就顯示
            ok.setText(""hello");//textview
        }
    };

謝謝大家
