I'm new here. I need your help because I don't know some thing. For example, I put a toolbar for my app and not an action bar in the top of the screen...now I want to put a toolbar in the bottom...so how could I do it? Toolbar is the correct way, and it is compatible with android 4.0+? Thank you for your answers.
EDIT: this is the code of mainactivity.xml which shows the toolbar in the top of the screen:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/container_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include
android:id="@+id/toolbar"
layout="@layout/toolbar" />
</LinearLayout>
<FrameLayout
android:id="@+id/container_body"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<ListView
android:id="@+id/drawer"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#FFF"
android:choiceMode="singleChoice"
android:divider="@android:color/transparent"
android:dividerHeight="0dp" />
