Question

我想在我的应用android页面中显示推送通知数据（从服务器网络发送）我的应用程序的主要活动代码是：

public class MainActivity extends AppCompatActivity implements
    RecyclerViewFragment.PostListListener, PostFragment.PostListener,
    TabLayoutFragment.TabLayoutListener, SearchResultFragment.SearchResultListener,
    CommentFragment.CommentListener {

private static final String TAG = MainActivity.class.getSimpleName();
public static final String TAB_LAYOUT_FRAGMENT_TAG = "TabLayoutFragment";
public static final String POST_FRAGMENT_TAG = "PostFragment";
public static final String COMMENT_FRAGMENT_TAG = "CommentFragment";

private FragmentManager fm = null;
private TabLayoutFragment tlf;
private PostFragment pf;
private CommentFragment cf;
private SearchResultFragment srf;
private String post_string;
private Post p;
private MainActivity mListener;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    //setContentView(R.layout.activity_main);
    OneSignal.idsAvailable(new OneSignal.IdsAvailableHandler() {
        @Override
        public void idsAvailable(String userId, String registrationId) {
            String text = "OneSignal UserID:\n" + userId + "\n\n";

            if (registrationId != null)
                text += "Google Registration Id:\n" + registrationId;
            else
                text += "Google Registration Id:\nCould not subscribe for push";



        }
    });

    OneSignal.setLogLevel(OneSignal.LOG_LEVEL.DEBUG, OneSignal.LOG_LEVEL.WARN);


    fm = getSupportFragmentManager();

    // Setup fragments
    tlf = new TabLayoutFragment();
    pf = new PostFragment();
    cf = new CommentFragment();
    srf = new SearchResultFragment();

    FragmentTransaction ft = fm.beginTransaction();
    ft.add(android.R.id.content, pf, POST_FRAGMENT_TAG);
    ft.add(android.R.id.content, cf, COMMENT_FRAGMENT_TAG);
    ft.add(android.R.id.content, tlf, TAB_LAYOUT_FRAGMENT_TAG);

    Intent intent = getIntent();
    if(intent.getStringExtra("post")!= null) {
        post_string =intent.getStringExtra("post") ;
        try {
            p =  JSONParser.parsePost(new JSONObject(post_string));
        } catch (JSONException e) {
            e.printStackTrace();
        }
        Log.d("pooooooooooooooooooooooooooooooooooooooost", p.getContent());
        this.onPostSelected(p, false);


    }

    ft.hide(pf);
    ft.hide(cf);
    ft.commit();
}

/**
 * Invoked when a post in the list is selected
 *
 * @param post Selected Post object
 */
@Override
public void onPostSelected(Post post, boolean isSearch) {
    // Find the fragment in order to set it up later
    pf = (PostFragment) getSupportFragmentManager().findFragmentByTag(POST_FRAGMENT_TAG);

    // Set necessary arguments
    Bundle args = new Bundle();
    args.putInt("id", post.getId());
    args.putString("title", post.getTitle());
    args.putString("date", post.getDate());
    args.putString("author", post.getAuthor());
    args.putString("content", post.getContent());
    args.putString("url", post.getUrl());
    //args.putString("thumbnailUrl", post.getThumbnailUrl());
    args.putString("featuredImage", post.getFeaturedImageUrl());

    // Configure PostFragment to display the right post
    pf.setUIArguments(args);

    // Show the fragment
    FragmentTransaction ft = fm.beginTransaction();
    ft.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right,
            android.R.anim.slide_in_left, android.R.anim.slide_out_right);
    if (!isSearch) { // Hide TabLayoutFragment if this is not search result
        ft.hide(tlf);
    } else { // Otherwise, hide the search result, ie. SearchResultFragment.
        ft.hide(srf);
    }
    ft.show(pf);
    ft.addToBackStack(null);
    ft.commit();
}
