Question

我正在尝试调整尺寸以适合出现键盘时的屏幕大小，我按照此处提供的说明进行操作：How to adjust layout when soft keyboard appears

但是似乎仍然无法正常工作，唯一上升的文字是“ Welcome to ....”，如果您降低我的输入框（用户名，密码，电子邮件，全名），以便当键盘出现时隐藏起来，因此即使“欢迎...”上移也不会发生任何事情。

我不知道问题可能出在这里，这是我的活动布局：

    </LinearLayout>




</RelativeLayout>




    </RelativeLayout>

这是我的AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapplication">

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".testLayout"
            android:windowSoftInputMode="adjustResize">
        </activity>
        <activity android:name=".registerActivity" />
        <activity android:name=".loginActivity" />
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar"
            android:windowSoftInputMode="adjustResize">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <meta-data
            android:name="preloaded_fonts"
            android:resource="@array/preloaded_fonts" />
    </application>

</manifest>

adjustResize也可以与constraintLayout一起使用！

谢谢。

尝试此操作将调整屏幕大小

将android：fitsSystemWindows =“ true”添加到scrollview

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:fillViewport="true"
android:layout_height="match_parent"
android:background="#000000"
android:fitsSystemWindows="true"
tools:context=".testLayout">

并在RelativeLayout中添加android：layout_gravity =“ center”

 <RelativeLayout
    android:id="@+id/mainLayout"
    android:layout_width="match_parent"
    android:layout_gravity="center"
    android:layout_height="wrap_content">

键盘显示时无法调整屏幕大小
