Not here, however I'm integrating it with Redux so that might be the issue. Will investigate more and see if I can replicate without Redux.
from react-navigation.
Can you explain a bit more what you mean? Which component? What's the use case?
from react-navigation.
If I had to guess, I think the OP meant:
Android back button handling (it just works, no need to do anything)
from react-navigation.
Sorry for not giving more details @satya164 . I have updated the desciption.
from react-navigation.
@vonovak I think what you're asking could be done easily with BackAndroid directly
componentDidMount() {
this._listener = BackAndroid.addListener('hardwareBackPress', () => {
if (shouldDoSomething) {
doSomething();
return true;
}
});
}
componentWillUnmount() {
this._listener.remove();
}
This is not declarative like a component, but let's the job done. And you could easily create a component for this if you need.
from react-navigation.
@satya164 I was assumming that the android back button "just works" out of the box - i.e. it does a pop()
unless I specify otherwise. That is not the case, it seems? (I updated the description again, sorry)
from react-navigation.
@vonovak yes, it works out of the box, and you can override it by attaching a listener in your component and returning true
from the listener.
from react-navigation.
ok, great! let me know where (what file of the docs) I should land a PR documenting this if you're interested.
from react-navigation.
@vonovak I'm not really sure. since the behaviour comes fromBackAndroid
. We're not doing anything special to allow you to override it.
from react-navigation.
@satya164 I see, no need for special docs, then.
from react-navigation.
@satya164 Just came across this. Using StackNavigator, when traversing down the stack (child pages), BackAndroid closes the app rather than navigating back up the stack until it hits the Init route, which would then close the app.
If this is intended, like you say it's easily handled - just I read this thread thinking the default behaviour would be like what I just described. Cheers
from react-navigation.
@Ehesp sorry I didn't get what you mean. doesn't back button behave the same as navigation.goBack
? can you open an issue with a sample if it doesn't?
from react-navigation.
@Ehesp Did you still have the same problem ? I have exactly the same issue but I fix it with what @satya164 said about BackAndroid
BackAndroid.addEventListener('hardwareBackPress', () => true);
I don't know if this is the correct solution but this doesn't closes my App and also allows me to navigate back keeping the navigators history.
from react-navigation.
@lndgalante you solve this problem already?
componentWillMount(){
BackHandler.addEventListener('hardwareBackPress', this._onBackAndroid)
}
_onBackAndroid = () => {
console.log(this.props.navigation.state.routeName)
if (this.lastBackPressed && this.lastBackPressed + 2000 >= Date.now()) {
return false;
}
this.lastBackPressed = Date.now();
toastShort('Press Again Exit App');
return true;
};
componentWillUnmount(){
BackHandler.removeEventListener('hardwareBackPress', this._onBackAndroid)
}
the method of _onBackAndroid does not work until back root route
