简书链接:拖动控件实现之Translation实现
文章字数：140,阅读全文大约需要1分钟
再次说下前提，不修改父布局，之移动自己，也不影响父容器的其它子控件 ，也不需要使用winManager的方式插入的view

binding.getRoot().setOnTouchListener(new View.OnTouchListener() {
          //            long pressTime = 0;
          float downX = 0;
          float downY = 0;
          boolean hasMove = false;
          int clickDistance = DensityUtil.dip2px(AppContext.getInstance(), 3);

          @Override
          public boolean onTouch(View v, MotionEvent event) {
              int actionMasked = event.getActionMasked();
              switch (actionMasked) {
                  case MotionEvent.ACTION_DOWN:

                      hasMove = false;
                      downX = event.getRawX();
                      downY = event.getRawY();

                      return true;
                  case MotionEvent.ACTION_MOVE:

                      hasMove = true;
                      View root = binding.getRoot();


                      float distanceX = event.getRawX() - downX;//表示触摸到哪里，但是 你滑动具体是多少是得转换的
                      float distanceY = event.getRawY() - downY;

                      int leftSrc = v.getLeft();
                      int rightSrc = v.getRight();
                      int topSrc = v.getTop();
                      int bottomSrc = v.getBottom();


                      int left = (int) (root.getLeft() + distanceX);
                      int right = (int) (root.getRight() + distanceX);
                      int top = (int) (root.getTop() + distanceY);
                      int bottom = (int) (root.getBottom() + distanceY);

                      if (BuildConfig.DEBUG) {
                          Prt.w(TAG, String.format("滑动距离%f y:%f src left %d,top%d right %d bottom%d modify left %d,top%d right %d bottom%d", distanceX, distanceY, leftSrc, topSrc, rightSrc, bottomSrc, left, top, right, bottom));
                      }
                      downX = event.getRawX();
                      downY = event.getRawY();



                      root.setTranslationX(root.getTranslationX()+distanceX);
                      root.setTranslationY(root.getTranslationY()+distanceY);
                      return true;


                  case MotionEvent.ACTION_UP:
                      if (hasMove) {
                          return true;

                      } else {
                          return false;
                      }
                  default:
                      return false;
              }
          }
      });

发现这种方式是不会因为父容器重测量而被还原，也不需要改动父容器，因此这种方法是最好的方法了，比margin实现靠谱，更比layout和offLeftAndRight方法靠谱
