显示android键盘时如何隐藏特定视图？

我试图编写一个代码来隐藏某些ui元素，当Android键盘显示时，我试图在清单中添加“adjustResize”，但它会自动重新调整元素的大小，但不会隐藏布局中的一些视图

MyCode:

package com.example.code;

import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

}
@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);


    // Checks whether a hardware keyboard is available
    if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
        Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
    } else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
        Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(this, "No above", Toast.LENGTH_SHORT).show();
    }
}  }

以上是我应用程序的代码和屏幕截图，所以我想在键盘打开时隐藏“测试布局”“文本视图。因此，请为我的问题提供一些技巧和解决方案。

您可以尝试类似的方法，并根据键盘的可见性更新布局的可见性

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);


    // Checks whether a hardware keyboard is available
    if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
        Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
    } else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
        Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
    }
}

同样的方式。您可以在片段中重写onConfigurationChanged方法，但我尝试了您的代码，但onConfigurationChanged没有被调用，即使我在Manifests中的活动中给出了android:configChanges=“orientation | keyboardHidden | screenSize”，它可以是很多东西。你可以查看一些关于为什么不调用它的想法。是的，我已经查看了那篇文章，但我应用了所有内容，请查看我更新的代码。。您可以正确地了解。是的，当我更改设备方向时，会调用该方法，这意味着从纵向到横向，但当我按下编辑文本时，键盘会弹出，此时我需要检查键盘是否打开。此布局是否有滚动视图？
