如何防止键盘打开时底部视图向上推

Question

[屏幕上有两个edittext，屏幕底部有一个按钮，问题是当我单击edittext并打开键盘时，底部的按钮出现在键盘上方，我希望底部按钮位于其原始位置而不是使用键盘向上移动。按钮在底部对齐

谢谢

P.S：我尝试过调整平底锅，调整大小等工作不正常

Answer 1

更新清单中活动标签中的以下内容：

android：windowSoftInputMode =“ adjustNothing”

Answer 2

像这样设置您的XML文件（根据需要进行更改）

    <androidx.constraintlayout.widget.ConstraintLayout android:id="@+id/linearLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

</androidx.constraintlayout.widget.ConstraintLayout>

并显示为此（示例）
<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=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

删除
WindowSoftInput模式。
