这里演示的是不修改父布局，也不导致父布局的其他子控件发生变化的实现方案，
int clickDistance = DensityUtil.dip2px(AppContext.getInstance(), 3);
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
// pressTime = System.currentTimeMillis();
hasMove = false;
downX = event.getX();
downY = event.getY();
return true;
case MotionEvent.ACTION_MOVE:
float moveX = event.getX();
float moveY = event.getY();
hasMove = true;
View root = binding.getRoot();
float distanceX =event.getX()-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.getY()- 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.getX();
downY = event.getY();
ViewGroup.MarginLayoutParams layoutParams = (ViewGroup.MarginLayoutParams) root.getLayoutParams();
layoutParams.leftMargin= layoutParams.leftMargin+(int) distanceX;
layoutParams.bottomMargin= layoutParams.topMargin+(int) distanceY;
root.setLayoutParams(layoutParams);
return true;
/* } else {
return false;
}*/
// offsetLeftAndRight(offX);
// offsetTopAndBottom(offY);
case MotionEvent.ACTION_UP:
if (hasMove) {
return true;
} else {
return false;
}
default:
return false;
}
存在的问题
发生了抖动问题，如何解决请关注我 第二篇文章
