android - 自定义底页对话框的视图

Question

我只想得到BottomSheetDialog如下信息：系统窗口的边距。我怎么会变成这样？

Answer 1

您可以通过以下方式创建底页对话框片段：

首先创建如下命名的xml文件

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>

现在创建一个名为的底部工作表片段

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));
    }

}

要调用该底部工作表片段，您可以编写如下：

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

我现在只使用了一个文本视图并附上了屏幕截图，因为您主要关心的是在底页中获得边距。同样通过这种方式，您可以根据需要自定义底页。谢谢！

添加依赖

implementation 'com.baoyz.actionsheet:library:1.1.7'

在活动中添加此代码

public void ButtonActionSheet() {

    ActionSheet.createBuilder(this, getSupportFragmentManager())
            .setCancelButtonTitle("Cancel")
            .setOtherButtonTitles("item1", "item2")
            .setCancelableOnTouchOutside(true)
            .setListener(new ActionSheet.ActionSheetListener() {
                @Override
                public void onDismiss(ActionSheet actionSheet, boolean isCancel) {

                }

                @Override
                public void onOtherButtonClick(ActionSheet actionSheet, int index) {

                    if (index == 0) {

                        myMethod();

                    } else if (index == 1) {

                        myMethod2();
                    }
                }


            })
            .show();




}

在 style.xml 中添加这一行

 <item name="actionSheetStyle">@style/ActionSheetStyleiOS7</item>
