                android:layout_height="wrap_content"
                android:id="@+id/bottomText"
                android:lineSpacingMultiplier="1.2"
                android:gravity="center"
                android:textColor="#626262"
                android:textSize="14sp"
                android:layout_centerHorizontal="true"
                android:layout_marginTop="15dp"
                android:width="270dp"
                android:layout_below="@+id/formulaire" />

        </RelativeLayout>
    </ScrollView>

</RelativeLayout>

But with different Device the imageViews are stick between them or are overlap. I think i have to use lines and rows, but i don't know how to di it.

Why don't you use TableLayout like this?

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/scroll">
        <TableLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">

            <TableRow>

                <ImageView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:id="@+id/topLogo1"
                    android:layout_marginTop="5dp"
                    android:src="@drawable/logo_bleu_petit"
                    android:layout_alignParentTop="true"
                    android:layout_centerHorizontal="true" />
            <ImageView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:id="@+id/topLogo2"
                    android:layout_marginTop="5dp"
                    android:src="@drawable/logo_bleu_petit"
                    android:layout_alignParentTop="true"
                    android:layout_centerHorizontal="true" />
            </TableRow>
            <TableRow>

                <ImageView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:id="@+id/topLogo3"
                    android:layout_marginTop="5dp"
                    android:src="@drawable/logo_bleu_petit"
                    android:layout_alignParentTop="true"
                    android:layout_centerHorizontal="true" />
                <ImageView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:id="@+id/topLogo4"
                    android:layout_marginTop="5dp"
                    android:src="@drawable/logo_bleu_petit"
                    android:layout_alignParentTop="true"
                    android:layout_centerHorizontal="true" />
            </TableRow>
        </TableLayout>
</ScrollView>

I hope this can fit your question.
