Make button stay visible when keyboard becomes visible

Question

I have the next layout

And when keyboard comes up, i wan't that green marked part of layout stays always visible. Another words i need to see both EditText and Button.

Here is my code sketch:

<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:fab="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:layout_margin="16dp"
tools:context="com.mynfo.concept.auth.AuthActivity">

<ImageView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:id="@+id/titleImageView"
    android:layout_gravity="center"
    android:src="@drawable/title_auth"
    android:layout_weight="0"
    android:layout_marginTop="48dp"
    android:layout_marginBottom="48dp"
    />

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_weight="0"
    android:layout_marginBottom="8dp"
    android:focusable="true"
    android:focusableInTouchMode="true"
    >

    <EditText
        android:id="@+id/barcode_editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="8dp"
        android:inputType="number"
        android:textColorHint="@color/darker_grey"

        android:ems="10"
        android:background="#0000"
        android:layout_gravity="left|center_vertical"/>

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@android:drawable/ic_menu_camera"
        android:layout_gravity="right|center_vertical"/>

    <View
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="@color/grey"
        android:layout_gravity="bottom"/>

</FrameLayout>

            android:layout_height="64dp"
            fab:fab_colorNormal=    "@color/turquoise"
            fab:fab_colorPressed=   "@color/turquoise_black"
            fab:fab_colorRipple=    "@color/turquoise_light"
            android:src="@android:drawable/ic_menu_camera"
            android:layout_gravity="center"/>
    </FrameLayout>

    <Button
        android:id="@+id/button_link_card"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Authorize"
        android:background="@drawable/button_authorize_selector"
        android:enabled="false"
        android:layout_weight="0"
        />

    <FrameLayout

        android:layout_weight="1.2">

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:layout_gravity="center"
            android:gravity="center">

            <TextView
                style="@style/TextViewPrimary"
                android:layout_marginLeft="32dp"
                android:layout_marginRight="32dp"
                android:textSize="16sp"
                android:text="Enter your name"
                android:gravity="center" />

            <com.mynfo.concept.views.FontFitTextView
                style="@style/TextViewSecondary"
                android:text="And then you will got the access"
                android:gravity="center" />

        </LinearLayout>


        <FrameLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/authenticatingView"
            android:background="#fff">

            <ProgressBar
                style="?android:attr/progressBarStyleLarge"
                android:indeterminateOnly="true"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/authenticatingProgressBar"
                android:layout_gravity="center"/>

        </FrameLayout>

    </FrameLayout>




</LinearLayout>

What haven't worked: adjustPan, adjustSize with or without layout weights.

Maybe I'm doing something wrong?

Thanks for the further help.

P.S. I know that this code feels redundant, but there were some purposes like screen adapting.

Answer 1

In your AndroidMenifest.xml file inside your tag use

windowsSoftInputMode = "adjustResize"

Or take whole layout inside ScrollView

windowsSoftInputMode = "adjustPan"

Example code snippet:

        <activity
            android:name=".activityname"
            android:label="@string/app_name"
            android:windowSoftInputMode="adjustPan|adjustResize" >

        </activity>

Use android:fillViewport="true" tag in ScrollView. And to avoid layout size bugs, use margin in Top ScrollView and don't use it in ScrollView child.

And add this in OnCreate

    scrollView = (ScrollView) this.findViewById(R.id.scrollView);
    scrollView.setVerticalScrollBarEnabled(false);
    imageView = (ImageView) findViewById(R.id.imageView);

    this.findViewById(android.R.id.content).addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
        @Override
        public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
            scrollView.scrollTo(0, imageView.getHeight() + ((ViewGroup.MarginLayoutParams) imageView.getLayoutParams()).topMargin);
        }
    });
