I'm trying to start this activity_main.xlm after a user's registration flow, but when I click on the button, the app closes. I work a little time with Android but I couldn't identify this error.
I need that after clicking the register button, the app remains pressed and calls activity_main.xml
As Logcat shows, the data passes through the api {"insert":"ok"}, but the application closes and does not call activity_main.
RegisterActivity.java
public class RegisterActivity extends AppCompatActivity {
EditText et_name, et_email, et_password, et_repassword;
Button btn_register, btn_login;
@Override
protected void onCreate(Bundle savedInstanceState) {
getSupportActionBar().setTitle("REGISTER");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_register);
et_name = findViewById(R.id.et_name);
et_email =findViewById(R.id.et_email);
et_password = findViewById(R.id.et_password);
et_repassword = findViewById(R.id.et_repassword);
btn_register= findViewById(R.id.btn_register);
btn_login = findViewById(R.id.btn_login);
btn_register.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(TextUtils.isEmpty(et_email.getText().toString()) || TextUtils.isEmpty(et_name.getText().toString()) || TextUtils.isEmpty(et_password.getText().toString()) || TextUtils.isEmpty(et_repassword.getText().toString())){
String message = "All input required";
Toast.makeText(RegisterActivity.this, message,Toast.LENGTH_LONG).show();
}else {
RegisterRequest registerRequest = new RegisterRequest();
registerRequest.setName_app(et_name.getText().toString());
registerRequest.setEmail_app(et_email.getText().toString());
registerRequest.setPassword_app(et_password.getText().toString());
sendRegister(registerRequest);
}
}
});
}
private void sendRegister(RegisterRequest registerRequest) {
Call<RegisterResponse> registerResponseCall=ApiClient.getService().registerUser(registerRequest);
registerResponseCall.enqueue(new Callback<RegisterResponse>() {
@Override
public void onResponse(Call<RegisterResponse> call, Response<RegisterResponse> response) {
if (response.isSuccessful()){
String message = "Successful";
Toast.makeText(RegisterActivity.this, message,Toast.LENGTH_LONG).show();
startActivity(new Intent(RegisterActivity.this,MainActivity.class));
finish();
}else{
String message = "An error occurred please try again later...";
Toast.makeText(RegisterActivity.this, message,Toast.LENGTH_LONG).show();
}
}
@Override
public void onFailure(Call<RegisterResponse> call, Throwable t) {
String message = t.getLocalizedMessage();
Toast.makeText(RegisterActivity.this, message,Toast.LENGTH_LONG).show();
}
});
}
}

CodePudding user response：
You should not get the support action bar before setcontentview is called.
Simply, move getSupportActionBar().hide(); after setContentView(R.layout.activity_main); and it should not crash anymore
Also please provide crash logs in the future, so we can debug quicker
