推荐答案

您可以通过以下方式创建底表"对话框片段:

You can create Bottom Sheet Dialog Fragment in following way:

首先创建如下名为

fragment_bottomsheet

fragment_bottomsheet

<?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="match_parent"
    android:background="@android:color/transparent"
    android:orientation="vertical">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="@dimen/_150sdp"
        android:layout_margin="@dimen/_20sdp"
        android:background="@drawable/round_corner_white3"
        android:orientation="vertical">

        <TextView
            android:id="@+id/tv_select_address"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:textColor="@color/white"
            android:background="@drawable/round_corner_gray"
            android:layout_margin="@dimen/_10sdp"
            android:layout_alignParentBottom="true"
            android:paddingBottom="@dimen/_10sdp"
            android:paddingTop="@dimen/_10sdp"
            android:text="Select Address" />

    </RelativeLayout>

</RelativeLayout>

现在创建一个名为

BottomSheetFragment

BottomSheetFragment

import android.app.Dialog;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.design.widget.BottomSheetDialogFragment;
import android.view.View;

public class BottomSheetFragment extends BottomSheetDialogFragment {

    public static BottomSheetFragment newInstance() {
        BottomSheetFragment fragment = new BottomSheetFragment();
        return fragment;
    }

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

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

}

要调用该底页片段，您可以编写以下内容:

To call that bottom sheet fragment you can write as below:

BottomSheetFragment bottomSheetDialog = BottomSheetFragment.newInstance();
bottomSheetDialog.show(getSupportFragmentManager(), "Bottom Sheet Dialog Fragment");

我现在只进行了一个textview并附加了屏幕截图，因为您主要关心的是在底页中留有余地.同样，您可以根据需要自定义底部工作表.谢谢！

I have only took a single textview for now and attaching the screenshot because your main concern is to get margin in bottomsheet. Also in this way you can customize bottom sheet as you want. Thanks!
