In the presenter I appeal to the database and in case of a successful response, I start a new activation from the view.

code :

mRepository.setUrl(resources.getString(R.string.url_server) + resources.getString(R.string.url_authorization)); mRepository.setJson(getJsonQuery()); mRepository.setRequest("post"); mRepository.loadResponse(new ModelDB.CompleteCallback() { @Override public void onComplete(String response) { mView.hideProgressDialog(); if (response.equals("successful")) { //авторизация пройдена успешна, перехожу к карте Intent intent = new Intent(mView.getContextView(), MapView.class); intent.putExtra("main_user", mView.getUsername()); intent.putExtra("tittle_user", mView.getUsername()); mView.startActivity(intent); } else { mView.showToast(response); }

code from View

 @Override public void startActivity(Intent intent) { startActivity(intent); }

mView and mRepository MVP application components.

Runtime error

In this case, the showToast method of the view works, there were no problems with the types. Tell me what I'm doing wrong?

    Try to transfer not the content in the view, but the data (main_user and tittle_user), and there you already have to pack in the intent - RomanK.

    Well, you have redefined the Activity method so that it always calls itself, so the stack ends. Either call the ancestor method via super , or rename the method in the interface so that you do not have to override it. - zRrr pm

Here, as already indicated in the comments,

 @Override public void startActivity(Intent intent) { startActivity(intent); }

Your method calls itself, which causes a StackOverflowError .

It is better to create a similar method in view:

Need to:

 @Override public void startMapActivity(String mainUser, String titleUser) { Intent intent = new Intent(this, MapView.class); intent.putExtra("main_user", mainUser); intent.putExtra("title_user", titleUser); startActivity(intent); }

And accordingly the challenge:

 mRepository.setUrl(resources.getString(R.string.url_server) + resources.getString(R.string.url_authorization)); mRepository.setJson(getJsonQuery()); mRepository.setRequest("post"); mRepository.loadResponse(new ModelDB.CompleteCallback() { @Override public void onComplete(String response) { mView.hideProgressDialog(); if (response.equals("successful")) { mView.startMapActivity(mView.getUsername(), mView.getUsername()); } else { mView.showToast(response); } } }
  • That's exactly what I did, thanks - Vadim Popov
