问题描述

我目前正在启动屏幕上用图像视图。问题是，显示启动画面时，有图像周围有白色边框。这样在启动画面显示与周围的白色边框的图像。我想彻底清除白色边框。有没有谁知道这个或任何建议？原因任何一个

下面是我的XML code：

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;
＆LT;的RelativeLayout的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
    机器人：layout_width =match_parent
    机器人：layout_height =WRAP_CONTENT＆GT;    ＆LT;景观的android：layout_width =match_parent
        机器人：layout_height =match_parent/＆GT;    ＆LT; ImageView的机器人：ID =@ + ID / ImageViewSplash
        机器人：layout_width =match_parent
        机器人：layout_height =match_parent
        机器人：adjustViewBounds =真
        机器人：scaleType =centerCrop
        机器人：contentDescription =@字符串/ splashImageContentDescription/＆GT;
＆LT; / RelativeLayout的＆GT;
 

解决方案

我申请在主题/风格我用我的形象页面透明背景，这样我就不必扭曲的形象显示，以适应该装置的屏幕尺寸。使用含有透明背景的PNG文件时，此效果尤其好。

下面是我用这个透明的主题风格：

 ＆LT;样式名称=Theme.Transparent父=安卓主题＆GT;
        ＆LT;项目名称=机器人：windowIsTranslucent＆GT;真＆LT; /项目＆GT;
        ＆LT;项目名称=机器人：windowBackground＆GT; @android：彩色/透明＆LT; /项目＆GT;
        ＆LT;项目名称=机器人：windowContentOverlay＆GT; @空＆LT; /项目＆GT;
        ＆LT;项目名称=机器人：windowNoTitle＆GT;真＆LT; /项目＆GT;
        ＆LT;项目名称=机器人：windowIsFloating＆GT;真＆LT; /项目＆GT;
        ＆LT;项目名称=机器人：backgroundDimEnabled＆GT;假LT; /项目＆GT;
    ＆LT; /风格＆GT;
 

您再申请这个主题溅活动应用程序清单如下：

 ＆LT;活动
        机器人：名字=com.masseria.homework9.SplashActivity
        机器人：configChanges =方向| keyboardHidden |屏幕尺寸
        机器人：标签=@字符串/ APP_NAME
        机器人：主题=@风格/ Theme.Transparent＆GT;
        ＆所述;意图滤光器＆gt;
            ＆lt;作用机器人：名字=android.intent.action.MAIN/＆GT;            ＆LT;类机器人：名字=android.intent.category.LAUNCHER/＆GT;
        ＆所述; /意图滤光器＆gt;
    ＆LT; /活性GT;
 

I am currently working on a splash screen with an image view. The problem is that when the splash screen is shown, there is a white border around the image. So that the splash screen shows the image with the white border around. I would like to remove the white border completely. Is there any one who know the reason for this or any suggestion?

Here is my xml code:

<?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" >

    <View android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <ImageView android:id="@+id/ImageViewSplash"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:adjustViewBounds="true"
        android:scaleType="centerCrop"
        android:contentDescription="@string/splashImageContentDescription" />
</RelativeLayout>

解决方案

I apply a transparent background in the theme/style I use for my splash pages, this way I don't have to distort the image being displayed to fit the screen size of the device. This works particularly well when using PNG files that contain a transparent background.

Here's the style I use for this "Transparent" theme:

    <style name="Theme.Transparent" parent="android:Theme">
        <item name="android:windowIsTranslucent">true</item>
        <item name="android:windowBackground">@android:color/transparent</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:backgroundDimEnabled">false</item>
    </style>

You then apply this theme to the splash activity in your application manifest as follows:

    <activity
        android:name="com.masseria.homework9.SplashActivity"
        android:configChanges="orientation|keyboardHidden|screenSize"
        android:label="@string/app_name"
        android:theme="@style/Theme.Transparent" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
