How to add a bottom menu to Android activity

Question

I'm trying to add another action bar or menu to the bottom of my activity layout and keep the top action bar.

Something like this :

Here is my Layout :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.example.yasser.version6.PublierActivity">


<include
    android:id="@+id/toolbar"
    layout="@layout/toolbar" />



<RelativeLayout
     android:layout_width="fill_parent"
     android:layout_height="match_parent"
     >


    <LinearLayout
        android:layout_width="fill_parent"
        android:id="@+id/user"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:weightSum="1">


        <ImageView
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_gravity="center"
            android:layout_margin="4dp"
            android:id="@+id/profil_image"
            android:layout_alignParentTop="true"
            android:layout_alignParentRight="true"
            android:layout_alignParentEnd="true"
            android:layout_marginRight="218dp"
            android:layout_marginEnd="218dp" />

        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textMultiLine|textCapSentences"
            android:ems="10"
            android:background="#00000000"
            android:layout_margin="4dp"
            android:hint="Écriver quelque chose..."
            android:id="@+id/publication_text"
            android:maxLength="150"
            android:textSize="15dp"
            android:maxLines="3"
            android:layout_alignParentTop="true"
            android:layout_alignParentLeft="true"
            android:layout_alignParentStart="true">
            <requestFocus />
        </EditText>


    </LinearLayout>




    <ImageView
        android:layout_width="fill_parent"
        android:layout_height="@dimen/image_size"
        android:id="@+id/publication_image"
        android:layout_weight="1"
        android:padding="0dp"
        android:background="@drawable/default_image"
        android:layout_marginTop="5dp"
        android:scaleType="fitXY"
        android:layout_below="@+id/user" />

</RelativeLayout>

I've tried to add a custom RelativeLayout which look almost like an action bar, but the toolbar goes up and mess up everything.

Answer 1

You can simply Add a toolbar and set it to bottom and simply can create your own custom layout.

 <android.support.v7.widget.Toolbar android:id="@+id/toolbar"
        android:layout_width="match_parent" android:layout_height="?attr/actionBarSize"
        android:background="#333333" app:popupTheme="@style/AppTheme.PopupOverlay"
        android:layout_alignParentBottom="true"

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

            <Button
                android:layout_width="50dp"
                android:layout_height="50dp"
                android:background="@drawable/folder"
                android:id="@+id/pdfViewer"/>

        </LinearLayout>
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:layout_gravity="center"
            >
            <Button
                android:layout_width="60dp"
                android:layout_height="60dp"
                android:background="@drawable/cameranew"
                android:id="@+id/btn"
                />
        </LinearLayout>
       </android.support.v7.widget.Toolbar> 

Answer 2

I made a custom Bottom bar with exact Height of ?attr/actionBarSize and ` layout_alignParentBottom="true" to put it in bottom.

<LinearLayout
    android:id="@+id/bottombar"
    android:layout_width="fill_parent"
    android:layout_height="?attr/actionBarSize"
    android:layout_alignParentBottom="true"
    android:background="#FFFFFF"
    android:weightSum="30"
    android:orientation="horizontal">

    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_gravity="center"
        android:background="@android:color/transparent"
        android:src="@drawable/iconcamera"/>
    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_gravity="center"
        android:background="@android:color/transparent"
        android:src="@drawable/shape"/>
</LinearLayout>`

Now goto Manifest.xml and in your activity tag put

android:windowSoftInputMode="adjustResize"

This will resize the layout on keyboard opening.

Creating custom bottom toolbar

I've already created a simple app which should demonstrate you how to begin

Creating a custom ViewGroup

Here's my activity_main.xml layout file:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="0dp"
    tools:context="com.example.piotr.myapplication.MainActivity">

    <LinearLayout
        android:id="@+id/show_pdf"
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:background="@color/primary_material_light"
        android:orientation="horizontal">

        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:src="@drawable/abc_ic_menu_cut_mtrl_alpha"/>

        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:src="@drawable/abc_ic_menu_copy_mtrl_am_alpha"/>

        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:src="@drawable/abc_ic_menu_selectall_mtrl_alpha"/>

        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:src="@drawable/abc_ic_menu_paste_mtrl_am_alpha"/>

        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:src="@drawable/abc_ic_menu_share_mtrl_alpha"/>

        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:src="@drawable/abc_ic_menu_selectall_mtrl_alpha"/>

        <ImageButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:src="@drawable/abc_ic_menu_moreoverflow_mtrl_alpha"/>
    </LinearLayout>

    <EditText
        android:id="@+id/editText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="75dp"
        android:ems="10"
        android:inputType="textPersonName"
        android:text="Name"/>
</RelativeLayout>

As you can see my parent ViewGroup is RelativeLayout, which simply allows me to create a view at the bottom of screen.

Notice that I set layout padding to zero (I think: setting layout margin to zero here is not necessary, the same effect). If you'd change it, the toolbar won't use full width and it won't stick with bottom of the screen.

Then I added a Linear Layout with hardcoded height which is:

          android:layout_height="40dp"

I wanted it, that my bottom toolbar would take full available width so I set it as match_parent.

Next, I added some ImageButton views with images from Android library.

There you have two possibilities:

• if you really want to have a toolbar like in above example just remove in every ImageButton view this line:

        android:layout_weight="1"
  

After removing weights and some buttons you would get a view pretty similar to expected:

• if you want to take the full width and make every button with the same size use in your project weight as in this mine example.

Now let's go to my AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.example.piotr.myapplication"
          xmlns:android="http://schemas.android.com/apk/res/android">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity
            android:name=".MainActivity"
            android:windowSoftInputMode="stateVisible|adjustResize">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>

In that file I'd added as you can see only one additional line:

         android:windowSoftInputMode="stateVisible|adjustResize">

to make sure that device keyboard won't hide my custom bottom toolbar.

If you have any question, please free to ask. I would answer them as quickly as possible.

Hope it help

That is a split action bar. It is available for handset devices with a screen width of 400dp< To enable split action bar, simply add uiOptions="splitActionBarWhenNarrow" to your or manifest element.

Edit: The second image is indeed not a split action bar. These are just buttons with the buttonBarButtonStyle attribute. Look into this here.
