Android layout_weight iframe and scroll

Question

sorry for my poor english in advance I have a design problem on android studio. I used multiples devices (From version 8 to 10) and it works fine, and one device (version 6) which has a different output (you can check my screens below)wrong display click here good display click here unfortunately i don't know why it goes wrong, it might be a problem with layout_weight, in my code i use a Frame layout to switch out between differents Views, it looks like the Framelayout doesn't take any height (i want it to take the available space) Thanks in advance

there is nothing displayed (ahead of the save button you should see the content of the good picture) — vincent mazyad, Jun 17 '20 at 19:24

You have the problem, because you have a FrameLayout inside a fragment. I recommend the next

If you only want to have a view and it has different content, you can have a activity

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_weight="0">

    <Spinner
        android:id="@+id/select_your_model"
        android:layout_width="43dp"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/text_model_title"
        android:layout_alignParentEnd="true" />

    <TextView
        android:id="@+id/text_model_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:layout_marginStart="5dp"
        android:layout_marginTop="20dp"
        android:text="@string/choose_mod"
        android:textSize="20sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/Spinner_model_preference_text"
        android:layout_width="160dp"
        android:layout_height="26dp"
        android:layout_alignTop="@+id/select_your_model"
        android:layout_alignParentEnd="true"
        android:layout_marginEnd="45dp"
        android:gravity="center"
        android:textColor="@android:color/darker_gray"
        android:textSize="16sp"
        android:textStyle="bold" />
</RelativeLayout>

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_marginTop="15dp"
    android:layout_weight="1"
    android:background="#FAFAFA">

    <FrameLayout
        android:id="@+id/Frame_layout_preferences_setting"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp" />
</ScrollView>

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginTop="20dp"
    android:layout_weight="0">

    <Button
        android:id="@+id/save_user_preferences"
        android:layout_width="wrap_content"
        android:layout_height="40dp"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:gravity="center"
        android:text="@string/save" />
</RelativeLayout>

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="0.2">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view_preferences_model"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true" />

    <View
        android:id="@+id/divider2"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:layout_above="@+id/recycler_view_preferences_model"
        android:layout_alignParentStart="true"
        android:background="?android:attr/listDivider" />
</RelativeLayout></LinearLayout>

Replace the FrameLayout with an imageview

if you want to have fragments. i recommend the next

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/main_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

Call the fragment in activity

getSupportFragmentManager().beginTransaction()
                    .replace(R.id.main_container, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();

i'll try to use an activity then, but i don't understand the problem of using fragment, i'm just adding views dynamically into my FrameLayout — vincent mazyad, Jun 17 '20 at 20:38
Because you have a FrameLayout inside a fragmen, it is not correct, because the fragment must be inside an activity — Alejandro Gonzalez, Jun 17 '20 at 20:48
