Android ANR keyDispatchingTimedOut Error while continuous tapping on screen

UI线程,主线程阻塞(blocking).新启一个线程,并由Handler来执行.

 

@Override
    public void onScroll(AbsListView view, final int firstVisibleItem,
            final int visibleItemCount, final int totalItemCount) {

        Thread songsList = new Thread(){
            @Override
            public void run(){
                firstItem = firstVisibleItem;
                visibleCout = visibleItemCount;
                totalCount = totalItemCount;
                Message message = new Message();
                message.what = 2;
                handler.sendMessage(message);
            }
        };
        songsList.start();

    }

Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            switch (msg.what) {
case 2:
                if ((firstItem + visibleCout == totalCount)
                        && (totalCount != 0)) {
                    if (refreshAble) {
                        refreshAble = false;
                        loading.setVisibility(View.VISIBLE);
                        /**
                         * 获取下一页数据
                         */
                        getData(++pageNo);
                    }
                }
                break;
            default:
                break;
            }
        }
    };
