软键盘：Adjust_Resize 将内容推送到屏幕外

Question

i'm build a messaging like application, but I am having some issue with the keyboard pushing up content wrong.

What I want is for the content to be pushed upward exactly as much as the keyboard is tall, and for me to be able to freely scroll upward to view all the previous messages. Just like most messaging apps.

Here is my layout. I add layouts to the layout inside the scrollview.

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/open_messsages_constraint"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".OpenMessages">


    <ScrollView
        android:id="@+id/messages_scroll2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintBottom_toTopOf="@id/linearLayout">


        <LinearLayout
            android:id="@+id/allMessage"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:orientation="vertical"
            app:layout_constraintTop_toTopOf="parent">

        </LinearLayout>


    </ScrollView>


    <LinearLayout
        android:id="@+id/linearLayout"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:background="#ffffff"
        android:backgroundTint="#ffffff"
        app:layout_constraintBottom_toBottomOf="parent">

        <EditText
            android:id="@+id/messageInput"
            android:layout_width="match_parent"
            android:layout_height="40dp"
            android:layout_gravity="center"
            android:layout_marginLeft="20dp"
            android:layout_weight="4"
            android:background="@drawable/rounded_corner"
            android:backgroundTint="#f1f1f1"
            android:paddingLeft="20dp"
            android:textColorLink="#000000" />


        <com.google.android.material.button.MaterialButton
            android:id="@+id/sendMessageButton"
            android:layout_width="50dp"
            android:layout_height="30dp"
            android:layout_gravity="center"
            android:backgroundTint="#ffffff"
            android:gravity="center"
            android:stateListAnimator="@null"
            app:iconTint="#000000">

        </com.google.android.material.button.MaterialButton>
    </LinearLayout>


</androidx.constraintlayout.widget.ConstraintLayout>

Here is before clicking the keyboard: Here is after. I can scroll downward sto view the message below, but I cannot scroll upward past this picture, so I am missing a message.

Answer 1

It's Work For Me :

android:windowSoftInputMode="adjustResize"

And Set Padding Of Your Recyclerview Bottom Padding.

padding:20

Answer 2

Replace your LinearLayout for allMessage with below:

<LinearLayout
            android:id="@+id/allMessage"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:orientation="vertical"
            android:layout_marginTop="50dp" // Add this line to view last messages
            app:layout_constraintTop_toTopOf="parent">

        </LinearLayout>
