在打开推送通知时启动片段吗？

Question

• 现在，我正在使用parse.com使用我的android应用将推送通知发送给用户。

• 我能够收到通知，点击应用程序即可正常启动。 我正在使用扩展ParsePushBroadCastReceiver的CustomBroadCastReceiver。

这是Receiver的代码：

package com.myapp;

import android.content.Context;
import android.content.Intent;

import com.parse.ParsePushBroadcastReceiver;

public class Receiver extends ParsePushBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        super.onReceive(context, intent);
    }

    @Override
    protected void onPushReceive(Context context, Intent intent) {
        super.onPushReceive(context, intent);
    }

    @Override
    protected void onPushDismiss(Context context, Intent intent) {
        super.onPushDismiss(context, intent);
    }

    @Override
    protected void onPushOpen(Context context, Intent intent) {
        super.onPushOpen(context,intent);
    }
} 

• 我正在尝试调用onPushOpen时打开WhatsNew片段。 但是问题是我正在为我的应用程序使用Navigationdrawer。 每当我单击通知应用程序登陆到启动活动时，MainActivity的代码如下：

   package com.myapp; import android.app.Fragment; import android.app.FragmentManager; import android.os.Bundle; import android.support.v4.widget.DrawerLayout; import android.support.v7.app.AppCompatActivity; import android.support.v7.widget.Toolbar; import com.parse.ParseAnalytics; import com.parse.ParseInstallation; public class MainActivity extends AppCompatActivity implements NavigationDrawerCallbacks { /** * Fragment managing the behaviors, interactions and presentation of the navigation drawer. */ private NavigationDrawerFragment mNavigationDrawerFragment; private Toolbar mToolbar; private static final String TAG = "MyActivity"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mToolbar = (Toolbar) findViewById(R.id.toolbar_actionbar); setSupportActionBar(mToolbar); mNavigationDrawerFragment = (NavigationDrawerFragment) getFragmentManager().findFragmentById(R.id.fragment_drawer); // Set up the drawer. mNavigationDrawerFragment.setup(R.id.fragment_drawer, (DrawerLayout) findViewById(R.id.drawer), mToolbar); ParseAnalytics.trackAppOpenedInBackground(getIntent()); ParseInstallation.getCurrentInstallation().saveInBackground(); } @Override public void onNavigationDrawerItemSelected(int position) { // update the main content by replacing fragments Fragment fragment; FragmentManager fragmentManager = getFragmentManager(); // For AppCompat use getSupportFragmentManager switch (position) { default: case 0: fragment = new Authentication();//search property break; case 1: fragment = new Home();//post property break; case 2: fragment = new PostRequirement();//post requirement break; case 3: fragment = new Properties();//popular locations keep it blank break; case 4: fragment = new Blog();//blog break; case 5: fragment = new Contact();//contact break; case 6: fragment = new NewFragment(); break; } fragmentManager.beginTransaction().replace(R.id.container, fragment).commit(); } @Override public void onBackPressed() { if (mNavigationDrawerFragment.isDrawerOpen()) mNavigationDrawerFragment.closeDrawer(); else super.onBackPressed(); } } 

• 在打开推送通知应用程序时，它将到达Authentication Fragment 。 我想要做的是每当用户通过推送通知打开应用程序时打开该NewFragment 。

该应用程序的清单文件：

• 我对此问题进行了大量研究，但没有得到满意的答案。 无法使用Intent来调用片段，因此无法在OnPushOpen方法中传递Intent

• 我应该怎么做，以便每当用户单击推送通知应用程序时，它将落在NewFragment而不是Authentication Fragment上。

• 感谢您花很长时间阅读问题！ 但是我真的很讨厌这个东西。

Answer 1

抱歉，收到推送通知时无法启动片段。 相反，您可以启动一个新活动，该活动可以在正确的屏幕/布局上显示新的通知。

为此，转到您的ParseApplication.java

public class ParseApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Parse.initialize(this, keys.applicationId, keys.clientKey);
        PushService.setDefaultPushCallback(this, NewActivity.java);
        ParseInstallation.getCurrentInstallation().saveEventually();
    }

基本上，当您收到通知并且用户单击时，它将加载NewActivity.java ，这将依次打开xml文件。

现在在NewActivity.java转到setContentView onCreate

setContentView(R.layout.**layout name**);

把你的XML文件。

如果要保留发送的推送通知，请使用共享首选项。

您应该从YourBroadCastReceiver向捆绑中添加一个参数，指示转到新的Fragment，然后从活动内部转到该Fragment，检查给定捆绑中的给定参数。
