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) subActivity;
//转发请求到子Activity
listener.onTabActivityResult(requestCode, resultCode, data);
}
super.onActivityResult(requestCode, resultCode, data);
}
public inte易做图ce OnTabActivityResultListener {
public void onTabActivityResult(int requestCode, int resultCode, Intent data);
}
