你可能喜欢BaseAdapter不更新是怎么回事
这个问题纠结我很久了，那位大虾要是看到了，帮我解决一下，谢谢了问题出在public void onTabActivityResult(int requestCode, int resultCode, Intent data) 这个方法里，在这个方法里调用
adapter = new ContactMainAdapter(AddNewActivity.this, list);
& & & & & & & & & & & & & & & & listView.setAdapter(adapter);
& & & & & & & & & & & & & & & & adapter.notifyDataSetChanged();
这样死活不更新，而不在这个方法里调用addDataSource()这个方法，是可以正常显示数据刷新的，我在里面这样调用这个方法也没用
下面这个是TabHost的那个Activity一段代码
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
& & & & // 获取当前活动的Activity实例
& & & & @SuppressWarnings(&deprecation&)
& & & & & & & & Activity subActivity = manager.getCurrentActivity();
& & & & //判断是否实现返回值接口
& & & & if (subActivity instanceof OnTabActivityResultListener) {
& & & & & & //获取返回值接口实例
& & & & & & OnTabActivityResultListener listener = (OnTabActivityResultListener) subA
& & & & & & //转发请求到子Activity
& & & & & & listener.onTabActivityResult(requestCode, resultCode, data);
& & & & super.onActivityResult(requestCode, resultCode, data);
& & & & public interface OnTabActivityResultListener {
& & & & & & & & &public void onTabActivityResult(int requestCode, int resultCode, Intent data);
