createChooserの後に他のアクティビティを起動します

Question

下記のようにcreateChooserによって起動されたアプリケーションが完了したら、どのように別のアクティビティにリダイレクトできますか？

私の試みでは、createChooserが起動する前に2番目のインテントがトリガーされてしまいます。新しく起動されたアクティビティの[戻る]ボタンを押すと、起動したいアクティビティにcreateChooserが表示されることに気付きました。

私はまた、startActivityForResultでcreateChooserをラップして、onActivityResult用いて第2の意図を起動しようとしましたが、結果は同じ

startActivity(Intent.createChooser(emailIntent, "Send mail...")); 
Intent trackIntent = new Intent(InformContacts.this, TrackOffers.class); 
startActivity(trackIntent); 

だったここで全体のコードです：

    informButton.setOnClickListener(new View.OnClickListener() { 
     @Override

      ArrayList emailsList = adapterContacts.emailsSelected; 
      String item = preferences.getString(ITEM_NAME, "item name"); 
      Float price = preferences.getFloat(ITEM_PRICE,0); 

      //May use the uriSharedPref string to embed actual url in email and show recipients like I did with publishing house 
      String sellingMessage = "Hello,\n\nI'm selling my "+ item +" for KES "+price+".\n\nGet back to me if you're interested in buying.\n\n" + uriSharedPref; 
      String subject = "Selling my "+item; 

      sendEmail(emailsList, sellingMessage, subject); 

      //Intent trackIntent = new Intent(InformContacts.this, TrackOffers.class);

     } 
    }); 
}

    //First Step: convert ArrayList to an Object array 
    Object[] objEmails = arrayOfEmails.toArray(); 
    //Second Step: convert Object array to String array 
    String[] strEmails = Arrays.copyOf(objEmails, objEmails.length, String[].class); 

    emailIntent.setData(Uri.parse("mailto:")); 
    emailIntent.setType("text/plain"); 
    emailIntent.putExtra(Intent.EXTRA_EMAIL, strEmails); 
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject); 
    emailIntent.putExtra(Intent.EXTRA_TEXT, message); 

    PackageManager packageManager = getPackageManager(); 
    List activities = packageManager.queryIntentActivities(emailIntent, PackageManager.MATCH_DEFAULT_ONLY); 
    boolean isIntentSafe = activities.size() > 0; 

    if(isIntentSafe){ 

     startActivityForResult(Intent.createChooser(emailIntent, "Send mail..."), REQUEST_SEND_EMAIL); 
     //finish(); 
     Log.i("Done sending email...", ""); 
    } 
    else{ 

     Toast.makeText(InformContacts.this, "No email app found. Email won't be sent.", Toast.LENGTH_SHORT).show(); 
    } 
} 

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data){ 

    super.onActivityResult(requestCode, resultCode, data); 

    if (resultCode == RESULT_OK){ 

     if(requestCode == REQUEST_SEND_EMAIL){ 

      Intent intent = new Intent(this, TrackOffers.class); 
      startActivity(intent); 
     } 
    } 
} 
} 

Answer 1

このを試しては、

変更：

代わりの

if(requestCode == REQUEST_SEND_EMAIL){ 

     Intent intent = new Intent(this, TrackOffers.class); 
     startActivity(intent); 
    } 

：確かに

if (resultCode == RESULT_OK){ 

    if(requestCode == REQUEST_SEND_EMAIL){ 

     Intent intent = new Intent(this, TrackOffers.class); 
     startActivity(intent); 
    } 
}
