问题 I've been using the new BottomSheetDialog added in Support Library 23.2, but I want to change the default height of the dialog. I know it probably has to do with the behavior_peekHeight attribute which controls the initial height, but how do I set that in the BottomSheetDialog when I don't have direct access to the BottomSheetBehavior ? 回答1: You can set a bottomSheetDialogTheme in your Activity, overriding the bottomSheetStyle attribute's behavior_peekHeight : <style name="AppTheme" parent=

Snippet from dependencies in build.gradle : compile 'com.android.support:support-v4:18.0.0' The support library is fetched from Android Support Repository installed via Android SDK Manager as explained here.

When the user does an important action, I want to allow them to undo it via the Snackbar, but there seems to be no way to detect when it is dismissed to do the action.

问题 When upgrading from the Android Support Library v23.4.0 to v24.0.0, setting the elevation to 0 programmatically to an AppBarLayout stopped working: appBayLayout.setElevation(0); It does work when setting the elevation in the XML. 回答1: Edit The AppBarLayout from v24.0.0 uses a StateListAnimator that defines the elevation depending on its state. So using setElevation will have no effect if a StateListAnimator is being used (which happens by default). Set the elevation via the XML or
