我遇到这个问题，我想修复布局的位置。我想将其修复在布局的中心，但每次单击 EditText 都会弹出键盘，TextView 就会向上移动，我不希望这样即将发生。这是我的代码:

</activity>
我尝试将我的 TextView 设置为 android:gravity="center_horizontal|center_vertical" 或尝试设置 android:centerVertical="true" 但前者产生完全相同的行为，后者使我的 TextView 甚至不显示。有什么方法可以修复 TextView 的位置吗？任何帮助将不胜感激，谢谢!
最佳答案
在Manifest.xml的activity标签中添加android:windowSoftInputMode="adjustPan"
