如何获得getIntent（）来调用一个Intent集活动后返回null [英] How to get getIntent() to return null after Activity called with an Intent set

问题描述

这个问题是类似于我原来的问题，但我觉得有一个更好的办法的办法解决。

This question was similar to my original question, but I think there is a better way to approach a solution.

<一个href=\"http://stackoverflow.com/questions/4348537/getintent-returns-wrong-intent-when-setintent-is-followed-by-a-rotation\">getIntent返回时setIntent后跟一个旋转的错意图

基本上，我的主要活动，它扩展了 FragmentActivity ，有两种情况，其中一个片段我通过一个Intent这一活动。

Basically, in my main Activity, which extends FragmentActivity, there are two instances where in a Fragment I pass an Intent to this Activity.

这是有问题的code：

This is the code that is having the problem:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(...);

    if (getIntent() != null && getIntent().getData() != null) {
        String data = getIntent().getDataString();
        //setIntent(null);

的 setIntent 是要解决我的问题的尝试，但未能奏效。

The setIntent was an attempt to solve my problem but it failed to work.

会发生什么事是，当我点击可以追溯到我的活动作为一个Intent一个链接，然后我去下一个片段，然后转动手机，这是通过两个片段前显示出来的时候，我再次致电意向 getIntent 。

What happens is when I click on a link that goes back to my Activity as an Intent, then I go to the next Fragment, then I rotate the phone, the Intent that was passed two Fragments ago shows up again when I call getIntent.

所以，当我得到的数据出来的意向，我怎么能设置这么 getIntent 的下一次调用将返回null？或者，它是有意义的只是在意向中的数据为空呢？

So, when I get the data out of the Intent, how can I set it so the next call to getIntent will return null? Or, would it make sense to just have the data in the Intent be null instead?

我试图避免在共享preferences更新信息来处理这个问题。

I am trying to avoid updating information in the SharedPreferences to handle this.

推荐答案

我发现，似乎工作的解决方案，但我希望有一个更好的方式来做到这一点。

I found a solution that appears to work, but I expect there is a better way to do it.

    if (getIntent() != null && getIntent().getData() != null) {
        String data = getIntent().getDataString();
        getIntent().setData(null);
        setIntent(null);

我觉得 setIntent 是没有任何用处，但使用setData（空）似乎做的招。

I think the setIntent isn't of any use, but the setData(null) seems to do the trick.
