如何在折叠工具栏布局下添加视图？

Question

I want to add collapsing toolbar in my app. I want to add a graph layout also image view and text views inside the collapsing toolbar layout. Like this image.

This graph is in collapsing toolbar layout. When we do scroll up graph goes up and remains as a toolbar.

Now I am trying to add views under collapsing toolbar layout. But I am not able to move them and align them. How to do?

        switch (v.getId()) {
            case R.id.fab1:
                text = fab1.getLabelText();
                break;
            case R.id.fab2:
                text = fab2.getLabelText();
                fab2.setVisibility(View.GONE);
                break;
            case R.id.fab3:
                text = fab3.getLabelText();
                fab2.setVisibility(View.VISIBLE);
                break;

        }
    }
    };
}

Now I have a single image view inside collapsing toolbar layout and that I can't move or align. How to align view and add views under collapsing toolbar?

Thank you..

Answer 1

CollapsingToolbarLayout is a subclass of FrameLayout .

For maximum flexibility, put all your widgets inside a LinearLayout or RelativeLayout and make it the only child of the CollapsingToolbarLayout . Also for best results with vertical sizing, set the height to a specific dimension.

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="@dimen/graph_toolbar_height"
        app:contentScrim="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_collapseMode="parallax">

            <!-- graph UI here -->

        </RelativeLayout>

    </android.support.design.widget.CollapsingToolbarLayout>

Create a layout inside collapsingtoolbarlayout and add your views in there.

<android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.design.widget.CollapsingToolbarLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:contentScrim="@color/colorPrimary"
            app:expandedTitleGravity="bottom|center_horizontal"
            app:expandedTitleMarginBottom="64dp"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical">

                <ImageView
                    android:layout_width="match_parent"
                    android:layout_height="230dp"
                    android:scaleType="centerCrop"
                    android:src="@drawable/ic_about"
                    app:layout_collapseMode="parallax" />

                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="48dp"
                    android:background="@color/colorAccent"
                    android:text="@string/about_title"
                    android:textSize="@dimen/text_size_large" />
            </LinearLayout>

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?actionBarSize"
                android:layout_marginTop="@dimen/status_bar_height"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/AppTheme.PopupOverlay" />

        </android.support.design.widget.CollapsingToolbarLayout>

    </android.support.design.widget.AppBarLayout>
