So I have following basic code which makes sure that my button goes up when a snackbar appers:
public class MoveUpwardBehavior extends CoordinatorLayout.Behavior<View> {
private static final boolean SNACKBAR_BEHAVIOR_ENABLED;
@Override
public boolean layoutDependsOn(CoordinatorLayout parent, View child, View dependency) {
return SNACKBAR_BEHAVIOR_ENABLED && dependency instanceof Snackbar.SnackbarLayout;
}
@Override
public boolean onDependentViewChanged(CoordinatorLayout parent, View child, View dependency) {
float translationY = Math.min(0, dependency.getTranslationY() - dependency.getHeight());
child.setTranslationY(translationY);
return true;
}
static {
SNACKBAR_BEHAVIOR_ENABLED = Build.VERSION.SDK_INT >= 11;
}
}
My customlinearlayout:
public class CustomLinearLayout extends LinearLayout implements CoordinatorLayout.AttachedBehavior {
MoveUpwardBehavior mb = new MoveUpwardBehavior();
public CustomLinearLayout(Context context) {
super(context);
}
public CustomLinearLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
public CustomLinearLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@NonNull
@Override
public CoordinatorLayout.Behavior getBehavior() {
return mb;
}
}
And last but not least my layout:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
app:layout_behavior=".pkgActivity.MoveUpwardBehaviour"
tools:context=".pkgTestforend.DriverListFragment">
<ListView
android:id="@+id/listAllDrivers"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ListView>
<com.example.dochjavatestimplementation.pkgTestforend.CustomLinearLayout
android:layout_width="match_parent"
android:id="@+id/cusLL"
android:layout_height="match_parent"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.material.floatingactionbutton.FloatingActionButton
android:id="@+id/btnOpenDriverAddFragment2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/baseline_person_add_24"
/>
</RelativeLayout>
</com.example.dochjavatestimplementation.pkgTestforend.CustomLinearLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
The result looks like this:
Which works perfectly fine, HOWEVER the issue is that if I remove the snackbar by sliding to the left/right, the button remains in the "upper" position:
How can I detect the MovingDown/Sliding to the right behaviour of my snackbar. Did I miss something important?
