Android: windowSoftInputMode = "adjustResize" does not affect the UI

I know there are similar questions in this regard. But I am completely helpless.
I have a multi-line editor that fits in LinearLayout

after multiple items. And when entering text, it is hidden.
The solution to this was to add the property android:windowSoftInputMode="adjustResize"

to the manifest file. It had no effect.
Further searching on SO, I found that I need to add a property android:fitsSystemWindows="true"

to the element of the root layout. However, it doesn't work. What is the problem?

Here is the manifest file:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.mytasks">
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name=".TaskDetails"
            android:label="@string/title_activity_task_details"
            android:windowSoftInputMode="adjustResize"
            >
        </activity>
    </application>
</manifest>

      

        
        
        
      

    

Operation layout file:
