android:为ListView 添加自定义头部和尾部,上拉主动加载 .(引)

分享到:

1.加头尾部


(1)定自义一个xml布局 my_headview.xml


在Activity类里找到这个自定义布局,并添加到头部


LinearLayout  hearderViewLayout = (LinearLayout) LayoutInflater.(
                        xwActivity.this).inflate(R.layout.my_headview, null);


listview.addHeaderView(hearderViewLayout);


(2)定自义一个xml布局 my_footview.xml


LinearLayout  footViewLayout = (LinearLayout) LayoutInflater.(
                        xwActivity.this).inflate(R.layout.my_footview, null);


listview.addFooterView(footerViewLayout);


(3)重视事务


listview必然会有Adapter,参加头尾部,必须在参加Adapter之前!


listview.addHeaderView(hearderViewLayout);


listview.addFooterView(footerViewLayout);


listview.setAdapter(myAdapter);


 


1.加上拉到尾部的监听件件


listview.setOnScrollListener(new OnScrollListener() {
            public void onScrollStateChanged(AbsListView view, int scrollState) {
                switch (scrollState) {
                case OnScrollListener.SCROLL_STATE_IDLE: // 当不迁移转变时
                    // 断定迁移转变到底部
                    if (view.getLastVisiblePosition() == (view.getCount() - 1)) {

                       //在这里添加操纵

                    }
                    break;
                }
            }

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

            }
        });
