I tried to set Margin in ButtonSheetDialogFragment layout but its not working. I have tried to set margin from layout and programatically but its has same result This is my XML file layout_bts_item.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp"
android:background="#00000000">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
</FrameLayout>
This is my java code
public class ButtomSheetFragment extends BottomSheetDialogFragment {
private BottomSheetBehavior.BottomSheetCallback mBottomSheetBehaviorCallback = new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_HIDDEN) {
dismiss();
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
}
};
@Override
public void setupDialog(Dialog dialog, int style) {
super.setupDialog(dialog, style);
View contentView = View.inflate(getContext(), R.layout.layout_bts_item, null);
dialog.setContentView(contentView);
CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) ((View) contentView.getParent()).getLayoutParams();
CoordinatorLayout.Behavior behavior = params.getBehavior();
if (behavior != null && behavior instanceof BottomSheetBehavior) {
((BottomSheetBehavior) behavior).setBottomSheetCallback(mBottomSheetBehaviorCallback);
int height = LayoutUtils.getScreenHeight(getActivity());
double desiredHeight = (0.85 * height);
((BottomSheetBehavior) behavior).setPeekHeight((int) desiredHeight);
contentView.getLayoutParams().height = (int) desiredHeight;
((FrameLayout.LayoutParams) contentView.getLayoutParams()).leftMargin = 100;
}
}
}
回答1:
Use this code for BottomSheetDialog
<style name="BottomSheetDialog" parent="Theme.Design.Light.BottomSheetDialog">
<item name="bottomSheetStyle">@style/bottomSheetStyleWrapper</item>
</style>
<style name="bottomSheetStyleWrapper" parent="Widget.Design.BottomSheet.Modal">
<item name="behavior_peekHeight">350dp</item>
<item name="android:layout_margin">30dp</item>
</style>
BottomSheetDialog dialog = new BottomSheetDialog(this, R.style.BottomSheetDialog);
dialog.setContentView(R.layout.custom_dialog);
dialog.show();
回答2:
Call requestLayout()
once you are done setting the margin.
In your case, something like
contentView.requestLayout();
after adding left margin.
