activity中核心代码

keyboardLayout.addOnLayoutChangeListener(new View.OnLayoutChangeListener() {

        @Override

        public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {

            if(oldBottom != -1 && oldBottom > bottom){

                recyclerView.requestLayout();

                recyclerView.post(new Runnable() {

                    @Override

                    public void run() {

                        recyclerView.scrollToPosition(mAdapter.getItemCount() - 1);

                    }

                });
