Mixing
Android “Top Sheet” equivalent of “Bottom Sheet”?
10
I am wanting to implement a "Bottom Sheet" type of layout, but with a twist where the "bottom" sheet will be a MapFragment, which won't work very well as an up/down draggable view.
I had a probably naive thought to "flip" the logic to a "Top Sheet" design, where you drag the Top Sheet up/down to show more/less of the bottom MapFragment.
ie: From this...
...to [something like] this...
Is this possible given the Support Design Tools, or will I have to roll something like this on my own?

I think you are going to sign up to do a substantial amount of heavy lifting to do two things. First, to create your custom implementation. Second, to identify how your implementation conflicts with the android implementation and to defend against those scenarios. My personal opinion, the Material Design Language has been put in place to visually communicate the ways your users can expect to interact with the app. Something like this may be great as a personal endeavour for learning, but once you hit the market - you need to expect that every single person won't understand how to use your app.

I ended up just adding a bottomsheet layout that has a Toolbar at its top that allows the user to drag the toolbar up. The trick is then to resize the Map as the user drags the toolbar. I can post my code if anyone is interested.

I'd like to see it @swooby, I'm trying to do something similar

@odiggity you can check my answer, I finally made it working exactly as the BottomSheetBehavior, but from the top.

did you encounter compatibility issues with this solution? in case you have a working app in the playstore using this functionality it'd be great to check it out :)

You can check my answer @swooby , perhaps it's nearer to what you were looking for. At least, it behaves exactly as I imagined a TopSheet to be equivalent to aBottomSheetBehavior.
– Carlos Alberto Martínez Gadea
Nov 21 '18 at 11:18
Looks good @CarlosAlbertoMartínezGadea, but the implementation in my answer current fits my needs for an existing production app, so I haven't experimented with porting over to yours. If I do one day I'll mark yours as the preferred answer! Thanks!

This TopSheetBehavior implementation ( https://github.com/MedveDomg/AndroidTopSheet/blob/master/library/src/main/java/com/github/techisfun/android/topsheet/TopSheetBehavior.java ) has proved to work pretty well in my case. I found many other TopSheetBehavior that were incomplete or that crashed, but this one doesn't crash and works out of the box by only replacing the behavior parameter:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:behavior_hideable="true"
app:behavior_peekHeight="56dp"
app:layout_behavior="your.package.components.TopSheetBehavior">
<!-- Your content goes here -->
</LinearLayout>

That's the perfect way to do that. It's working smoothly and fine.

Can I use this exact solution in closed source project? Or should I provide some references?

@ViktorVostrikov yes, you can. It's under the Apache license. Here you have a few questions answered about the usage of code under the Apache license: resources.whitesourcesoftware.com/blog-whitesource/…

@CarlosAlbertoMartínezGadea however it is stated that I need to still write somehow the owner of the library.. Don't know there should I provide credentials..

@ViktorVostrikov to me, the phrase "If you redistribute software with any Apache licensed components, you must include a copy of the license, provide a clear Apache License attribution, and add modification notices to all the files that you modify." explains the situation quite clearly. You don't need to contact the author of the code but you must show that you are using the Apache License, with a link to that license.

Here is the basis of my solution that I commented about above.
I will come back and flesh it out later.
@Override

@Nullable
Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
if (isFinishing())
{
return;
}
setContentView(R.layout.activity_home);
...
mGroupBottomSheetFiller = (ViewGroup) findViewById(R.id.groupBottomSheetFiller);
final NestedScrollView bottomSheetMap = (NestedScrollView) findViewById(R.id.bottomSheetMap);
mBottomSheetMapBehavior = BottomSheetBehavior.from(bottomSheetMap);
mBottomSheetMapBehavior.setBottomSheetCallback(new BottomSheetCallback()
{
@Override
public void onStateChanged(
@NonNull
View bottomSheet,
int newState)
{
//Log.e(TAG, "mBottomSheetMapBehavior.onStateChanged(bottomSheet, newState=" +
// bottomSheetBehaviorStateToString(newState) + ')');
int visibility = isBottomSheetExpanded(mBottomSheetMapBehavior) ? View.VISIBLE : View.GONE;
mImageBottomSheetMapClose.setVisibility(visibility);
}
@Override
public void onSlide(
@NonNull
View bottomSheet,
float slideOffset)
{
//Log.e(TAG, "mBottomSheetMapBehavior.onStateChanged(bottomSheet, slideOffset=" + slideOffset + ')');
resizeMap();
}
});
bottomSheetMap.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener()
{
@Override
public void onGlobalLayout()
{
//Log.e(TAG, "onGlobalLayout()");
bottomSheetMap.getViewTreeObserver().removeOnGlobalLayoutListener(this);
resizeMap();
}
});

}

mGroupMap.getLocationInWindow(location);
//Log.e(TAG, "resizeMap: getLocationInWindow=" + Arrays.toString(location));

did you encounter compatibility issues with this solution? in case you have a working app in the playstore using this functionality it'd be great to check it out :)

May 29 '17 at 15:33
You can check my answer @swooby , perhaps it's nearer to what you were looking for. At least, it behaves exactly as I imagined a TopSheet to be equivalent to aBottomSheetBehavior.

Nov 21 '18 at 11:18
Looks good @CarlosAlbertoMartínezGadea, but the implementation in my answer current fits my needs for an existing production app, so I haven't experimented with porting over to yours. If I do one day I'll mark yours as the preferred answer! Thanks!

This TopSheetBehavior implementation ( https://github.com/MedveDomg/AndroidTopSheet/blob/master/library/src/main/java/com/github/techisfun/android/topsheet/TopSheetBehavior.java ) has proved to work pretty well in my case. I found many other TopSheetBehavior that were incomplete or that crashed, but this one doesn't crash and works out of the box by only replacing the behavior parameter:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
app:behavior_hideable="true"
app:behavior_peekHeight="56dp"
app:layout_behavior="your.package.components.TopSheetBehavior">
<!-- Your content goes here -->
</LinearLayout>

@ViktorVostrikov to me, the phrase "If you redistribute software with any Apache licensed components, you must include a copy of the license, provide a clear Apache License attribution, and add modification notices to all the files that you modify." explains the situation quite clearly. You don't need to contact the author of the code but you must show that you are using the Apache License, with a link to that license.

I think you are going to sign up to do a substantial amount of heavy lifting to do two things. First, to create your custom implementation. Second, to identify how your implementation conflicts with the android implementation and to defend against those scenarios. My personal opinion, the Material Design Language has been put in place to visually communicate the ways your users can expect to interact with the app. Something like this may be great as a personal endeavour for learning, but once you hit the market - you need to expect that every single person won't understand how to use your app.

I ended up just adding a bottomsheet layout that has a Toolbar at its top that allows the user to drag the toolbar up. The trick is then to resize the Map as the user drags the toolbar. I can post my code if anyone is interested.
