实现动态添加自定义View到约束布局（constraints ）--------附：自定义可拖拽View

ConstraintSet constraints = new ConstraintSet();
                constraints.clone(constraint);
// Define our ImageView and add it to layout

                TagView imageView = new TagView(MainActivity.this);
                imageView.setId(View.generateViewId());
                constraint.addView(imageView);


// Now constrain the ImageView so it is centered on the screen.

// There is also a "center" method that can be used here.

                constraints.constrainWidth(imageView.getId(), ConstraintSet.WRAP_CONTENT);

                constraints.constrainHeight(imageView.getId(), ConstraintSet.WRAP_CONTENT);

                constraints.center(imageView.getId(), ConstraintSet.PARENT_ID, ConstraintSet.LEFT,

                        0, ConstraintSet.PARENT_ID, ConstraintSet.RIGHT, 0, 0.5f);

                constraints.center(imageView.getId(), ConstraintSet.P
