如何在两个不同的活动中进行多个深层链接而不重复应用程序android [英] How to make multiple Deep Linking in two different activity without duplicate the app android
问题描述
我正在使用深层链接将我的活动链接共享给不同的应用程序，如WhatsApp. 问题是我想分享2个不同的活动. 现在，我可以共享它们了，但是如果我们假设我将共享活动A. 单击链接后，我会很好地看到我的应用程序选项，它将带我进入活动A.
I am using deep linking to share my active link to different applications like WhatsApp. The problem is I want to share 2 different activities. Now I am able to share them but if we assume I will share activity A. After clicking on the link, I will see my application option well that's fine and it will take me to activity A.
但是现在，如果我确实共享活动B.当我尝试单击链接时，我的应用程序将一次出现两次，如果我选择了活动A先前选择的内容，它将带我进入活动答:这是错误的选择，因此请求的活动将无法进行.
But now if I do share to activity B.When I try to click on the link, my application will appear twice at one time, and if I choose what was previously chosen by activity A, it will take me to my activity A.This is a wrong choice, so the requested activity will not work.

这是清单代码:
<!-- 1-->
<activity
android:name=".FragmanM.MainActivityM" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="http"
android:host="============"
android:pathPrefix="/post" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="https"
android:host="==============="
android:pathPrefix="/post" />
</intent-filter>
</activity>
<!-- 2 -->
<activity
android:name=".FragmantA.MainActivityA" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="http"
android:host="================"
android:pathPrefix="/posts" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data
android:scheme="https"
android:host="==============="
android:pathPrefix="/posts" />
</intent-filter>
</activity>
此活动A
Uri data =getActivity(). getIntent().getData();
if (data!= null) {
try {
post_id = data.getLastPathSegment().toString();
getPost(post_id);
} catch (NumberFormatException e) {
post_id=null;
}
}
Bundle bundle = getActivity().getIntent().getExtras();
if (bundle !=null){
if(post_id==null){
post_id =bundle.getString("mid");
getPost(post_id);
}
}
这是活动B
Uri data =getActivity(). getIntent().getData();
if (data!= null) {
try {
posts_id = data.getLastPathSegment().toString();
getPost(posts_id);
} catch (NumberFormatException e) {
posts_id=null;
}
}
Bundle bundle = getActivity().getIntent().getExtras();
if (bundle !=null){
if(posts_id==null){
posts_id =bundle.getString("moid");
getPost(posts_id);
}
}
推荐答案
您的两个活动都提供了意图过滤器，但是这样做的原因是，您提供了类似的路径前缀.
Both of your activities are providing intent filters but the reason for this is, you are providing a similar path prefix.
我的意思是，这是您的第一次活动，即您提到的.FragmanM.MainActivityM
What I mean by this is in your first activity i.e .FragmanM.MainActivityM you have mentioned
<data
android:scheme="http"
android:host="============"
android:pathPrefix="/post" />
在.FragmantA.MainActivityA中，您已经写了这个
<data
android:scheme="http"
android:host="============"
android:pathPrefix="/posts" />
现在来看一下pathPrefix
根据定义并根据文档pathPrefix:
By the definition and according to documentation pathPrefix :
pathPrefix属性指定匹配的部分路径 仅针对Intent对象中路径的初始部分
The
pathPrefixattribute specifies a partial path that is matched against only the initial part of the path in the Intent object
因此，当您遇到这样的链接时: www.yourhost.com/posts 第一个活动也会显示出来，第二个活动也会显示出来.
So when you come across links such as this: www.yourhost.com/posts the first activity also gets shown and the second one also showed which is expected.
那该如何解决呢?
方法1:在这种情况下，您可以从第二个活动中删除意图过滤器，并让单个活动处理两条路径.FragmanM.MainActivityM
Method 1: You can remove intent-filter from your second activity and have single activity handle both paths in this case .FragmanM.MainActivityM
在该活动中进行这样的签入onCreate()
and inside that activity make a check-in onCreate() somewhat like this
Uri data = getIntent().getData();
if(data.getPath().startsWith("/posts"))
{
//Start Your second activity here
}
方法2:创建一个全新的活动，仅用于处理链接，然后从此处过滤链接并将用户移动到其他屏幕
Method 2: Create a whole new activity just to handle links and from there you filter links and move the user to different screens
