通过屏幕触控事件实现加载更多

lv = (ListView) findViewById(R.id.lv);

list = new ArrayList<>();

//初始化数据

initData();

adapter = new MyAdapter(this,list);

lv.setAdapter(adapter);

//滑动监听事件

lv.setOnScrollListener(new OnScrollListener() {

//view listview的item

//scrollState 滑动的状态

@Override

public void onScrollStateChanged(AbsListView view, int scrollState) {

if(scrollState ==OnScrollListener.SCROLL_STATE_IDLE){

//滑动停止时，并且是最后一个item时我让其加载更多

if(view.getLastVisiblePosition()==list.size()-1){

index+=10；

//加载更多;

initData();

adapter.notifyDataSetChanged();

}

}

}

@Override

public void onScroll(AbsListView view, int firstVisibleItem,

int visibleItemCount, int totalItemCount) {

// TODO Auto-generated method stub

}

});

}

private void initData() {

for (int i = index; i <index+10; i++) {

list.add("我是item");

}

}
