如何在我的应用程序中进行 DeepLink - Android

Question

我想将这篇文章内容（标题、摘要、图片等...）加载到我的activity。 发布链接： Link 。
我可以将此数据加载到activity，对于这项工作，我使用Retrofit作为连接方式并将adapter的数据加载到Recyclerview，当点击RecyclerView项目时，将Bundle的帖子内容发送到其他activity!

活动代码：（使用此代码，我提供来自 recyclerview 项目的数据。）

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.post_show_page);

        bindActivity();

        // Initialize
        context = PostShow_page.this;
        favDB = new FavHelper(context);
        postShow_favPost = (ShineButton) mToolbar.findViewById(R.id.post_FavImage);
        post_cover = (ImageView) findViewById(R.id.postShow_cover_image);
        postShow_title = (TextView) findViewById(R.id.postShow_title);
        postShow_title2 = (TextView) findViewById(R.id.postShow_titleBig);
        //postShow_content = (TextView) findViewById(R.id.postShow_content_text);
        postShow_dateTime = (TextView) findViewById(R.id.postShow_man_date_text);
        postShow_author = (TextView) findViewById(R.id.postShow_man_author_text);
        postShow_category = (TextView) findViewById(R.id.postShow_man_category_text);
        title_sliding = (TextView) findViewById(R.id.post_sliding_title);
        comment_Recyclerview = (RecyclerView) findViewById(R.id.comment_recyclerView);
        post_content_web = (WebView) findViewById(R.id.postShow_content_web);
        mLayoutManager = new LinearLayoutManager(this);

        mAdaper = new CommentAdapter2(context, models);

        //Give Data
        Bundle bundle = getIntent().getExtras();

        if (bundle != null) {
            postID = bundle.getInt("postID");
            title = bundle.getString("title");
            image = bundle.getString("image");
            content = bundle.getString("content");
            dateTime = bundle.getString("dateTime");
            author = bundle.getString("author");
            category = bundle.getString("category");
            categoryID = bundle.getString("categoryID");
        }

        // Deep Linking
        Intent intent = getIntent();
        for (String key : intent.getExtras().keySet()) {
            Log.e("Deep", key);

        }

        mAppBarLayout.addOnOffsetChangedListener(this);
        // Setup comment RecyclerView
        comment_Recyclerview.setLayoutManager(mLayoutManager);
        comment_Recyclerview.setHasFixedSize(true);
        postShow_favPost.init(this);
        postShow_favPost.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (postFavState == 0) {
                    /// Add to Database
                    favDB.insertFAV(context, title, image, content, dateTime, author, category);

                    postFavState++;

                } else {

                    postShow_favPost.setBtnColor(ContextCompat.getColor(context, R.color.favColorON));
                    postShow_favPost.setBtnFillColor(ContextCompat.getColor(context, R.color.favColorON));

                }
            }
        });

        if (favDB.checkFavPost(title)) {

            postShow_favPost.setBtnColor(ContextCompat.getColor(context, R.color.favColorON));
            postShow_favPost.setBtnFillColor(ContextCompat.getColor(context, R.color.favColorOFF));

        } else {
            postShow_favPost.setBtnColor(ContextCompat.getColor(context, R.color.favColorOFF));
            postShow_favPost.setBtnFillColor(ContextCompat.getColor(context, R.color.favColorON));
        }


        //mToolbar.inflateMenu(R.menu.post_menu);
        mToolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {

        }

        if (content != null) {

            post_content_web.getSettings().setJavaScriptEnabled(true);

        mAppBarLayout = (AppBarLayout) findViewById(R.id.postShow_appBar);
    }

    private void bindData() {

        // Setup Connect
        Retrofit_ApiInterface apiInterface = Retrofit_ApiClient.getClient().create(Retrofit_ApiInterface.class);
        Call<R_CatModelResponse> call = apiInterface.getCatResponse(postID);

        Log.d("PostID", "Post : " + postID);

        call.enqueue(new Callback<R_CatModelResponse>() {
            @Override
            public void onResponse(Call<R_CatModelResponse> call, Response<R_CatModelResponse> response) {

                if (response != null) {

                    models.addAll(response.body().getCat_posts().get(0).getComments());
                    mAdaper.notifyDataSetChanged();

                    Toast.makeText(PostShow_page.this, "GoTo Adapter", Toast.LENGTH_SHORT).show();
                    comment_Recyclerview.setAdapter(mAdaper);

                }
            }

            @Override
            public void onFailure(Call<R_CatModelResponse> call, Throwable t) {
                Toast.makeText(PostShow_page.this, "Failed", Toast.LENGTH_SHORT).show();
            }
        });
    }

如果你打开上面的链接，你会在这篇文章中看到另一个链接，（另一个链接到上面的帖子链接LINK），我想要点击其他链接进入帖子。打开此链接进入我的应用程序，不是网络浏览器。

对于这份工作，我知道我应该使用 Deep Link，我将此代码添加到我的 manifest 和 activity 中。

<activity
            android:name=".Activities.PostShow_page"
            android:screenOrientation="portrait"
            android:theme="@style/AppThemeWithStatus">

            <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:host="www.kolony.ir"
                    android:scheme="http" />

                <data
                    android:host="kolony.ir"
                    android:scheme="http" />

            </intent-filter>

        </activity>

我想在 PostShow_page 活动中显示帖子内容，当再次点击链接时，将帖子内容打开到 activity！

我的 POJO 类（带有 setter 和 getter）：

public class R_CatModel {

    @SerializedName("id")
    public Integer id;
    @SerializedName("type")
    public String type;
    @SerializedName("slug")
    public String slug;
    @SerializedName("url")
    public String url;
    @SerializedName("status")
    public String status;
    @SerializedName("title")
    public String title;
    @SerializedName("title_plain")
    public String title_plain;
    @SerializedName("content")
    public String content;
    @SerializedName("excerpt")
    public String excerpt;
    @SerializedName("date")
    public String date;
    @SerializedName("modified")
    public String modified;
    @SerializedName("comment_count")
    public int comment_count;
    @SerializedName("comment_status")
    public String comment_status;
    @SerializedName("thumbnail")
    public String thumbnail;
    @SerializedName("thumbnail_images")
    public R_CatThumbnailImages thumbnail_images;
    @SerializedName("categories")
    public List<R_CatCategory> categories;
    @SerializedName("author")
    public R_CatAuthor catAuthor;
    @SerializedName("comments")
    public List<R_PostComment> comments;

我该怎么办？如何打开链接，进入我的应用程序而不是网络浏览器？

请帮助我亲爱的兄弟们，我真的需要这个。谢谢大家

要使您的应用与网站完美的 DeepLink，您必须遵循一些步骤。我做到了并且成功了。您需要在 manifest.xml 文件中的相应（要打开的活动）块内添加几行。

1 步：-

    <activity android:name="com.recipe_app.client.RecipeActivity"
              android:label="@string/app_name" >
        <intent-filter android:label="@string/app_name">
            <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="recipe-app.com"
                  android:pathPrefix="/recipe" />
        </intent-filter>
    </activity>

2 步：-

在 .java 文件中添加几行。哪个加载该视图。在 onCreate() 中添加以下代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_recipe);
    onNewIntent(getIntent());

     try {
       Intent intent = getIntent();
       String action = intent.getAction();
       Uri data = intent.getData();
       if (Intent.ACTION_VIEW.equals(action) && data != null) {
           String articleId = data.getLastPathSegment();
           data.getPathSegments();
           String value = data.getPath();
            /* Here you will receive that complete URL from which currently opend URL you come.*/

       }
   }catch (Exception e){e.printStackTrace();}


}
