I'm trying to code 2 activities with startActivityForResult. But my activity does not call onActivityResult.
EDIT : I open an dialogBox. When i click on Cancel, the box must not show up again. When i click on remind me later, if i go to the second acitivty and go back to home, the box must show up.
I don't understand. I have check on stack overflow but no right anwser.
Can you help me please =)
Thx
First activity :
...
public void onCreate(Bundle saveInstance) {
...
Intent i = new Intent(HomeActivity.this, EstablishmentActivity.class);
int idEstablishment = listEstablishment.get((int)id).getIdEstablishment();
Log.d(TAG, "id = "+idEstablishment);
i.putExtra("idEstablishment", idEstablishment);
i.putExtra("GPS", wantGPS);
Log.d(TAG, "wantGPS : " + wantGPS);
//Start Intent
startActivityForResult(i, WANTGPS);
...
}
...
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
Log.d(TAG, "go on actovoty rsult");
if (requestCode == WANTGPS) {
if (resultCode == Activity.RESULT_OK) {
wantGPS = intent.getExtras().getBoolean("GPS");
Log.d(TAG, "result : "+wantGPS);
}
}
}
And 2nd activity :
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.establishment_main);
// Set up the action bar.
final ActionBar actionBar = getActionBar();
if (actionBar == null) {
Log.d(TAG, "actionBar is null !");
}
//Set up the left icon to go back to Home Page
actionBar.setDisplayHomeAsUpEnabled(true);
Intent i = getIntent();
wantGPS = i.getBooleanExtra("GPS", false);
Log.d(TAG, "wantGPS 2 "+wantGPS);
}
...
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == android.R.id.home) {
Intent result = new Intent(EstablishmentActivity.this, HomeActivity.class);
result.putExtra("GPS", wantGPS);
setResult(RESULT_OK, result);
finish();
}
return super.onOptionsItemSelected(item);
}
I have the answer !! If you have the same problem than me, this answer should help you :)
I had define parent activity on the manifest. So android does not look into "OnOptionItemSelected".
I removed parent activity on manifest and it works !
According to answers on this post:
Try the following code instead:
Intent result = new Intent();
result.putExtra("GPS", wantGPS);
setResult(RESULT_OK, result);
finish();
Using the simpler Intent()
constructor seems to solve a lot of problems.
It may be a good idea ensure the value you're using for reqCode (WANTGPS) is positive.
I had previously run into problems with (randomly-generated) negative reqCodes, and onActivityResult didn't get fired about half of the time(when reqCode goes negative); OTOH small integers (1,2,100,...) seem to work fine. ReqCode might have an upper limit as well. Unfortunately I could not find any mention to this kind of behavior in the docs though; the Android documentation did not seem to explain what reqCode should be.
