<android.support.v7.widget.Toolbar> and does not show the image

Question

I’m wearing and the picture’s not showing

Answer 1

@Marcelo CL your question was not very clear. You are trying to make a picture Toolbar ?

A good behavior that we always see in apps and use a Toolbar that hides the image.

Here is an example of how to do, imagining that this is what you need.

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout
    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"
    android:fitsSystemWindows="true">

    <com.google.android.material.appbar.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="200dp"
        android:background="@android:color/transparent"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

        <com.google.android.material.appbar.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorAccent"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <androidx.appcompat.widget.AppCompatImageView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:background="@color/colorAccent" />

            <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:layout_collapseMode="pin"
                app:navigationIcon="@drawable/ic_arrow_back"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />
        </com.google.android.material.appbar.CollapsingToolbarLayout>

    </com.google.android.material.appbar.AppBarLayout>

    <androidx.core.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fillViewport="true"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <!-- TODO Your content here -->

    </androidx.core.widget.NestedScrollView>

</androidx.coordinatorlayout.widget.CoordinatorLayout>
