向 BottomSheetDialogFragment 添加边距

Question

我已经尝试为我的 BottomSheetDialogFragment 添加边距，但是它对边距没有任何作用。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_margin="16dp">

    <TextView
        android:id="@+id/alertdialog_fragmail_newmessage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Test 1"
        android:textStyle="bold"
        android:padding="16dp"
        android:textColor="@color/colorBlackFont"
        android:layout_alignParentTop="true"
        android:gravity="center_vertical"
        android:drawablePadding="16dp"/>


  //More Textviews

</RelativeLayout>

我已经尝试将 XML 更改为下面的答案，但是它仍然没有为我的底部 sheetdialogfragment 创建边距。

底部 sheet 对话框片段的代码 class:

public class FragMailMoreDialog extends BottomSheetDialogFragment {

    private static final String TAG = "FragMailMoreDialog";

    private Context mContext;


    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mContext = getContext();
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater,
                             @Nullable ViewGroup container,
                             @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.alertdialog_layout_fragmailmore, container, false);
        ButterKnife.bind(this, view);


        return view;
    }
}

底部充气代码sheet:

private void inflateMoreDialog(){
        FragMailMoreDialog moreDialog = new FragMailMoreDialog();
        if (getFragmentManager() != null) {
            moreDialog.show(getFragmentManager(), "FRAGMAIL_MORE_DIALOG");
        }
    }

Answer 1

不确定为什么要为 BottomSheetDialogFragment 添加边距。它是一个显示在 Activity/Fragment 之上的 DialogFragment。添加边距不会做任何事情。如果您需要的是 TextView (Test1) 的顶部填充和 TextView (Test2) 的底部填充，那么您应该将 padding_top 添加到 Test1 并将 padding_bottom 添加到 Test2，例如：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_margin="16dp">

    <TextView
        android:id="@+id/alertdialog_fragmail_newmessage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Test 1"
        android:textStyle="bold"
        android:paddingTop="32dp"
        android:paddingStart="16dp"
        android:paddingEnd="16dp"
        android:paddingBottom="16dp"
        android:textColor="@color/colorBlackFont"
        android:layout_alignParentTop="true"
        android:gravity="center_vertical"
        android:drawablePadding="16dp"/>
</RelativeLayout>

Answer 2

有点老套的解决方案：

我将我的布局包裹在另一个 RelativeLayout 中，并使该布局的背景透明。

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:background="@android:color/transparent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorWhite"
        android:layout_margin="16dp">

    <TextView
        android:id="@+id/alertdialog_fragmail_newmessage"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Test 1"
        android:textStyle="bold"
        android:padding="16dp"
        android:textColor="@color/colorBlackFont"
        android:layout_alignParentTop="true"
        android:gravity="center_vertical"
        android:drawablePadding="16dp"
        android:background="?attr/selectableItemBackground"/>
    </RelativeLayout>
</RelativeLayout>

并且在 BottomSheetDialogFragment 中你需要覆盖 setupDialog

@Override
    public void setupDialog(Dialog dialog, int style) {
        View contentView = View.inflate(getContext(), R.layout.alertdialog_layout_fragmailmore, null);
        dialog.setContentView(contentView);
        ((View) contentView.getParent()).setBackgroundColor(getResources().getColor(android.R.color.transparent));
    }

我给 Constraint child 添加了 margin 并且给 parent Constraint 背景透明 Bottom Sheet layout Image

Answer 4

有效 100%

覆盖onCreateDialog()return你自己的对话框

   override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
  
        return Dialog(requireActivity()).apply {
            setContentView(viewBinding.root)
            window!!.setBackgroundDrawableResource(R.drawable.dialog_background)
            window!!.setGravity(Gravity.BOTTOM)
            window!!.setLayout(500.toPx(),500.toPx())
        }
  
}

Answer 5

覆盖 setupDialog() 对我不起作用，而且我还需要使用 onCreateView() 来扩充对话框布局。因此，这可以在自定义 BottomSheetDialogFragment class:

中以编程方式解决

创建无背景样式并在 onCreateDialog 或 getTheme()

<style name="NoBackgroundDialogTheme" parent="Theme.AppCompat.Light.Dialog">
    <item name="android:windowBackground">@null</item>
</style>

使用对话框布局根部的layoutParams设置边距

Java:

public class FragMailMoreDialog extends BottomSheetDialogFragment {

    //.... Omitted code

        
    @Override
    public int getTheme() {
       // Step 1
       return R.style.NoBackgroundDialogTheme;
    }


    @Override
    public void onViewCreated(@NonNull @NotNull View view, @Nullable @org.jetbrains.annotations.Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        
        // Step 2
        addMargin(view);

    }

    private void addMargin(View view) {
        FrameLayout.LayoutParams layoutParams =
                (FrameLayout.LayoutParams) view.getLayoutParams();
        int margin_16dp = dpToPx(16);
        layoutParams.setMargins(margin_16dp, margin_16dp, margin_16dp, margin_16dp);
        view.setLayoutParams(layoutParams);
        view.requestLayout();
    }

    private int dpToPx(int dp) {
        Resources r = getResources();
        int px = (int) TypedValue.applyDimension(
                TypedValue.COMPLEX_UNIT_DIP,
                dp,
                r.getDisplayMetrics()
        );
        return px;
    }

}

科特林：

class FragMailMoreDialog() : BottomSheetDialogFragment() {

    override fun getTheme(): Int {
        return R.style.NoBackgroundDialogTheme
    }

    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View {

        val view: View = View.inflate(context, R.layout.my_fragment_bottomsheet, null)
        return view
    }


    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        addMargin(view)
    }

    private fun addMargin(view: View) {
        val layoutParams: FrameLayout.LayoutParams =
            view.layoutParams as FrameLayout.LayoutParams
        val margin_16dp = 16.toPx().toInt()
        layoutParams.setMargins(margin_16dp, margin_16dp, margin_16dp, margin_16dp)

        view.layoutParams = layoutParams
    }


    fun Number.toPx() = TypedValue.applyDimension(
        TypedValue.COMPLEX_UNIT_DIP,
        this.toFloat(),
        Resources.getSystem().displayMetrics
    )

}

Answer 6

类似于@Zain 的回答：

override fun onCreateView(...) {
    ...
}

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)

    // FrameLayout.LayoutParams, CoordinatorLayout.LayoutParams or other container in your root layout.
    ((view.parent as View).layoutParams as FrameLayout.LayoutParams).topMargin = 100
}

Answer 7

您可以在 stiles.xml 中完成。请注意，要使 bottom_margin 起作用，您实际上需要添加负值 top_margin（请参阅 -10dp），这会将所有内容向上移动 10dp。

<style name="AppBottomSheetDialogTheme" parent="Theme.Design.Light.BottomSheetDialog">
    <item name="bottomSheetStyle">@style/AppModalStyle</item>
    <item name="android:windowIsTranslucent">false</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:backgroundDimAmount">0.5</item>
    <item name="android:windowFrame">@null</item>
    <item name="android:windowIsFloating">true</item>
</style>

<style name="AppModalStyle" parent="Widget.Design.BottomSheet.Modal">
    <item name="android:background">@drawable/bottom_menu_back</item>
    <item name="android:layout_marginStart">10dp</item>
    <item name="android:layout_marginEnd">10dp</item>
    <item name="android:layout_marginTop">-10dp</item>
</style>
