Android(安卓)listView scroll 恢复滚动位置

相信大家尝试过许多方法恢复滚动位置，本人也找了许多方法，唯有这个方法好用，下面把代码贴出来

声明两个变量

private int mPosition;private int lvChildTop;

pause , resume方法

        @Overridepublic void onPause() {// TODO Auto-generated method stubsuper.onPause();SharedPreferences mySharedPreferences = activity.getSharedPreferences(MY_PREFS, Activity.MODE_PRIVATE);SharedPreferences.Editor edit = mySharedPreferences.edit();edit.putInt("mPositionChildTop", lvChildTop);edit.putInt("mPosition", mPosition);edit.commit();}@Overridepublic void onResume() {// TODO Auto-generated method stubsuper.onResume();SharedPreferences mySharedPreferences = activity.getSharedPreferences(MY_PREFS, Activity.MODE_PRIVATE); // MY_PREFES 是声明的字符串lvChildTop = mySharedPreferences.getInt("mPositionChildTop", 0);mPosition = mySharedPreferences.getInt("mPosition", 0);listMessage.setSelectionFromTop(mPosition, lvChildTop); // listMessage 是listview ，}

listview 的监听事件

private OnScrollListener lvScrollListener = new OnScrollListener() {@Overridepublic void onScrollStateChanged(AbsListView view, int scrollState) {// TODO Auto-generated method stub// 不滚动时保存当前滚动到的位置if (scrollState == OnScrollListener.SCROLL_STATE_IDLE) {mPosition = listMessage.getFirstVisiblePosition();View v = listMessage.getChildAt(0);lvChildTop = (v == null) ? 0 : v.getTop();}}@Overridepublic void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {// TODO Auto-generated method stub}};
