Question

我正在尝试在应用程序上使用ViewPager2，但是在实现它时遇到了一些问题。

问题：

当我单击EditText时，出现键盘，并且 ViewPager2调整大小，更改Height

我想要的：

当我点击EditText时，出现键盘并移动查看而不调整ViewPager2的大小。

如何防止ViewPage2调整大小并仅在出现键盘时向上移动视图？
有什么属性要设置吗？

这是我的清单

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

    <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"
        android:windowSoftInputMode="stateVisible">

        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

这是我的ViewPager2

布局错误/我想要什么

Answer 1

尝试将其添加到AndroidManifest的“活动”中：

checkbox.addEventListener('change', (e) => {
  if (e.target.checked) {
    // add a class or specific styles here
  } else {
    // remove prev updates
  }
});

您还可以测试android:windowSoftInputMode="adjustPan"和adjustResize，以了解哪种方法最适合您。
