android自定义对话框如何修改布局外的半透明遮罩？

Question

自定义CustomDialog继承Dialog后设置相应的布局后，想问问如何控制对话框外的半透明背景？
代码如下：

package com.mxjy.ssep.ui.subassembly;

import android.app.Dialog;
import android.content.Context;
import android.graphics.Point;
import android.os.Bundle;
import android.text.TextUtils;
import android.view.Display;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.view.View;
import android.view.WindowManager;
import android.widget.EditText;
import android.widget.TextView;

import androidx.annotation.NonNull;

import com.mxjy.ssep.R;
import com.mxjy.ssep.softKeyboard.KeyboardUtil;
import com.mxjy.ssep.ui.other.MyTransformation;
import com.mxjy.ssep.util.LogUtils;

效果如下：

Answer 1

在style文件中添加如下代码：
<style name="myDialogTheme" parent="@android:style/Theme.Dialog">
        <item name="android:windowNoTitle">true</item>
        <item name="android:backgroundDimEnabled">false</item>
 </style>
其中这个 <item name="android:backgroundDimEnabled">false</item>设置是对话框外侧是否启用半透明遮罩开关。

创建时使用CustomDialog6 customDialog6 = new CustomDialog6(getContext(),keyboardUtil,R.style.myDialogTheme);
传递对应的主题编号。

对应的构造函数中使用如下代码即可：
public CustomDialog6(@NonNull Context context,KeyboardUtil keyboardUtil,int themeResId) {
        //super(context);
        super(context,themeResId);
        this.keyboardUtil = keyboardUtil;
    }
