ll_collect.setOnClickListener(new View.OnClickListener() {
            boolean state = false;
            @Override
            public void onClick(View v) {
                //收藏
                if(state==false){
                    state = true;
                    iv_collect.setImageDrawable(getDrawable(R.drawable.collect));
                }else if(state==true){
                    state = false;
                    iv_collect.setImageDrawable(getDrawable(R.drawable.uncollect));
                }
            }
        });
