I want to make an application looks like that photo..
When I click the button to MainActivity on sub-activities, OnActivityResult() and OnNewIntent() are all called in MainActicity.
I intend to call OnActivityResult() for coming back from MenuActivity, and to call OnNewIntent() for coming back from subs.
I learned mother activity calls child activity through StartActivityForResult(), and child calls setResult() for return. And when the objective activity that I want to call is alive, I learned onNewContent() is needed because objective activity doesn't call onCrete().
But I think I'm wrong. Plz let me know what is the difference of OnActivityResult() and OnNewResult()? and also I want to know why OnActivityResult is called even though setResult is not called in setResult().
Thank you in advance.

@Override
public void onClick(View v) {
if(editText.getText().toString().length() != 0 &&
editText2.getText().toString().length() != 0){
Intent intent = new Intent(getApplicationContext(), MenuActivity.class);
startActivityForResult(intent, REQUEST_CODE_MENU);
} else {

MenuActivity.java
public class MenuActivity extends AppCompatActivity {
public static final int REQUEST_CODE_CUSTOM = 200;

CustomActivity.java (one of sub activities, it's code is perfectly same with other sub-activities)
public class CustomActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_custom);
Button tomenu = (Button) findViewById(R.id.tomenu);
Button tologin = (Button) findViewById(R.id.tologin);
tomenu.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent from_cus = new Intent(getApplicationContext(), MenuActivity.class);
from_cus.putExtra("from", "CustomActivity");
setResult(RESULT_OK, from_cus);
finish();
}
});
tologin.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent from_cus = new Intent(getApplicationContext(), MainActivity.class);
from_cus.putExtra("from", "CustomActivity");
from_cus.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP|Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(from_cus);
finish();
}
});
}
}
