如何在点击推送通知时打开 Fragment

Question

我用于传递意图的 Firebasemessagingservice 类代码：

private void showNotification(String message){
    Intent intent=new Intent(this, DrawerActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("data", message);
    PendingIntent pendingIntent=PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder=new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentTitle("Registry")
            .setContentText(message)
            .setSmallIcon(R.drawable.com_facebook_button_send_icon_blue)
            .setContentIntent(pendingIntent);
    NotificationManager manager=(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    manager.notify(0,builder.build());
}

我在 onCreate() 方法中的 Fragment BaseActivity 代码：

Intent notifyIntent = getIntent();
    Bundle extras = notifyIntent.getExtras();
    if (extras != null) {

       replacefragment code;

    }

它不工作..

您需要发送带有意图数据的密钥并使用该密钥进行检查并执行类似的代码

private void showNotification(String message){
    Intent intent=new Intent(this, DrawerActivity.class);
    intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    intent.putExtra("data", message);
     intent.putExtra("KEY", "YOUR VAL");
    PendingIntent pendingIntent=PendingIntent.getActivity(this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);

    NotificationCompat.Builder builder=new NotificationCompat.Builder(this)
            .setAutoCancel(true)
            .setContentTitle("Registry")
            .setContentText(message)
            .setSmallIcon(R.drawable.com_facebook_button_send_icon_blue)
            .setContentIntent(pendingIntent);
    NotificationManager manager=(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    manager.notify(0,builder.build());
}

并检查 Activity 之类的

Intent notifyIntent = getIntent();
   String extras = getIntent().getExtraString("KEY");;
    if (extras != null&&extras.equals("YOUR VAL")) {`enter code here`

       replacefragment code;

    }

如果活动已经打开，还要检查 onIntent 变化

首先，在代码中，您是否让通知以下一种方式声明意图：

Intent intent=new Intent(getApplicationContext(), MyClass.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("menuFragment", "MyFragment");
PendingIntent pendingIntent=PendingIntent.getActivity(MyClass.this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);

将意图分配给 mBuilder

mBuilder.setContentIntent(pendingIntent);

然后转到活动 main 并在 onCreate 方法中添加以下代码：

protected void onCreate(Bundle savedInstanceState) {
    onNewIntent(getIntent());
}

最后在 MainActivity 中添加此方法：

@Override
    protected void onNewIntent(Intent intent) {
        Bundle extras = intent.getExtras();
        if(extras != null){
            if(extras.containsKey("menuFragment"))
            {
                FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
                fragmentTransaction.replace(R.id.detail_fragment_container, MyFragment.newInstance() ).commit();
            }
        }
    }
