应用栏上方的空白区域 [英] Empty space above the app bar

问题描述

如何摆脱下面显示的空白空间(水平红线之间的空间)?直到买到一部新手机(三星S8)，它的垂直屏幕空间都比我以前的HTC One多，我才在我的应用程序上看到它.

How do I get rid of the empty space shown below (the space between the horizontal red lines)? I didn't see this on my app until getting a new phone (Samsung S8), which has more vertical screen space than my old HTC One.

该活动的布局文件的开头是:

The beginning of the layout file for that activity is:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
<LinearLayout ...

我的值-v14/styles.xml是

My values-v14/styles.xml is

<resources>

    <!--
        Base application theme for API 14+. This theme completely replaces
        AppBaseTheme from BOTH res/values/styles.xml and
        res/values-v11/styles.xml on API 14+ devices.
    -->
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- API 14 theme customizations can go here. -->
    </style>

</resources>

我尝试使用Google搜索该问题，但找不到任何内容-我必须搜索错误的术语.我需要编辑什么文件才能消除应用程序操作栏上方的空白?

I tried googling this problem but I couldn't find anything -- I must be searching for the wrong terms. What file do I need to edit to make the empty space above my app's action bar go away?

为了进行比较，这是该应用在模拟器中的外观(在我的HTC One上是相同的方式):

for comparison, here's what the app looks like in the emulator (it looks the same way on my HTC One):

当我在Samsung S8上运行该应用程序时，我希望该应用程序具有与上述相同的行为(即操作栏上方没有黑色空间).我需要更改什么?

I'd like the app to behave the same way as above (i.e. no black space above the action bar) when I run it on my Samsung S8. What do I need to change?

推荐答案

这是由于Samsung Galaxy S8的宽高比较大而发生的.默认情况下，Android应用程序支持最大纵横比为16:9.要解决此问题，请将此元素添加到清单中的<application>标记内:

This is happening due to the wider aspect ratio of the Samsung Galaxy S8. By default, Android applications support a maximum aspect ratio of 16:9. To solve, add this element inside the <application> tag in your manifest:

<meta-data android:name="android.max_aspect" android:value="2.1" />
