对话框布局双层错误透明背景 [英] Dialog layout double layered wrong transparant background

问题描述

我想做一个白色，没有边框，弹出视图。要实现这一点，我使用自定义样式的自定义对话框：

  public Builder createNewDialog（int type）{
 AlertDialog .Builder dlg = null; 
 switch（type）{
 case（1）：
 
 dlg = new AlertDialog.Builder（new ContextThemeWrapper（this，
 R.style.CustomDialogTheme））; 
 
 LayoutInflater inflater = this.getLayoutInflater（）; 
 
 dlg.setView（inflater.inflate（R.layout.dialognewplayer，null））
 .setPositiveButton（Add Player，null）.setNegativeButton（Cancel，null）.create （）; 
 break; 
} 
 return dlg; 
} 
  

// styles.xml：

 <？xml version =1.0encoding =utf-8？> 
< resources> 
 
< style name =AppThemeparent =android：Theme.Light>< / style> 
< style name =CustomDialogThemeparent =android：Theme.Dialog> 
< item name =android：windowBackground> @ color / transparent_color< / item> 
< item name =android：windowIsFloating> false< / item> 
< item name =android：windowNoTitle> true< / item> 
< item name =android：background>＃ffffff< / item> 
< / style> 
 
< / resources> 
  

//和colors.xml

 <？xml version =1.0encoding =utf-8？> 
< resources> 
< color name =transparent_color>＃ffffff< / color> 
< / resources> 
  

但是，如图所示，弹出窗口有一些错误...似乎双层，第一层仍然有一个边框，透明的背景仍然是黑色的..我想我处理错误，但我没有看到它...

解决方案

使用透明主题，并使用android自己的透明色。

 < style name =CustomDialogTheme parent =@ android：style / Theme.Translucent> 
< item name =android：windowIsFloating> false< / item> 
< item name =android：windowNoTitle> true< / item> 
< item name =android：background> @android：color / transparent< / item> 
< / style> 
  

I want to make a white, no bordered, popup view. To accomplish this I use a custom dialog with a custom style:

public Builder createNewDialog(int type) {
        AlertDialog.Builder dlg = null;
        switch (type) {
        case (1):

            dlg = new AlertDialog.Builder(new ContextThemeWrapper(this,
                    R.style.CustomDialogTheme));

            LayoutInflater inflater = this.getLayoutInflater();

            dlg.setView(inflater.inflate(R.layout.dialognewplayer, null))
                    .setPositiveButton("Add Player", null).setNegativeButton("Cancel", null).create();
            break;
        }
        return dlg;
    }

//styles.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="AppTheme" parent="android:Theme.Light"></style>
    <style name="CustomDialogTheme" parent="android:Theme.Dialog">
         <item name="android:windowBackground">@color/transparent_color</item>
        <item name="android:windowIsFloating">false</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:background">#ffffff</item>
    </style>

</resources>

//and colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
       <color name="transparent_color">#ffffff</color>
</resources>

However, as you can see at the image, the popup has some errors... it appears to be double layered with the first layer still having a border, and the transparant background is still black.. I think I am handling something wrong but I am not seeing it...

解决方案

Use the Translucent Theme and use android own transparent color.

<style name="CustomDialogTheme" parent="@android:style/Theme.Translucent">
    <item name="android:windowIsFloating">false</item>
    <item name="android:windowNoTitle">true</item>
    <item name="android:background">@android:color/transparent</item>
</style>
