ToolBar (AppCompat) Example in Android.

This project has been created in Android Studio using Android 5.0 SDK. and This example can run in lower versions also for that i have used AppCompat library.

Screen Shot:

Note: Make sure you have added AppCompat-V7 library to your Android Studio Project as follows.
build.gradle:
apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "materialdesignapp.ram.com.materialdesignapp"
        minSdkVersion 10
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
}

Create colors.xml file under res folder and include following colors as shown below.
colors.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="primary">#009688</color>
    <color name="primary_dark">#00796B</color>
    <color name="accent">#9C27B0</color>
</resources>

under styles.xml include following styles as follows.
styles.xml:
<resources>
    
    <style name="AppTheme" parent="AppTheme.Base">
        
    </style>

    <style name="AppTheme.Base" parent="Theme.AppCompat.NoActionBar">
        
        <item name="colorPrimary">@color/primary</item>
        <item name="colorPrimaryDark">@color/primary</item>
        <item name="colorAccent">@color/primary</item>
    </style>
</resources>

Next create values-v21 folder under res folder and copy styles.xml from values folder and paste in under values-v21 folder or create new styles.xml under values-v21 folder and include following styles as shown below.
styles.xml:
<resources>
    
    <style name="AppTheme" parent="AppTheme.Base">
        
        
        
        <item name="android:colorPrimary">@color/primary</item>
        
        <item name="android:colorPrimaryDark">@color/primary_dark</item>
        
        <item name="android:colorAccent">@color/accent</item>
    </style>

</resources>

Next under layout folder create new xml file called apptool_bar.xml and include following code as shown below
apptool_bar.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/primary">
</android.support.v7.widget.Toolbar>

Next under activity_main.xml include apptool_bar layout using include tag as shown below.
activity_main.xml:
<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"
    tools:context=".MainActivity">

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

    <TextView
        android:text="@string/hello_world"
        android:layout_below="@+id/apptool_bar"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>

Next under MainActivity call the reference of ToolBar and set that to action bar as follows.
MainActivity.java:
package materialdesignapp.ram.com.materialdesignapp;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;

public class MainActivity extends ActionBarActivity {
    Toolbar toolbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        toolbar = (Toolbar) findViewById(R.id.apptool_bar);

        setSupportActionBar(toolbar);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

ActionBarCompat-ShareActionBarProvider Example in Android

Screen Shots:

In this project we used some images those are stored in assets folder. Those images you can get from the project below.

Download Android Studio Project here : click here

How to develop this project:

First we need to create menu folder under res folder and create new xml file called main_menu.xml as follows and include following code.

main_menu.xml:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:support="http://schemas.android.com/apk/res-auto">
    <item
        android:id="@+id/menu_share"
        android:title="@string/menu_share"
        support:actionProviderClass="android.support.v7.widget.ShareActionProvider"
        support:showAsAction="always" />

</menu>

next you need to include values(strings,colors,dimens,styles..etc,..) from above downloadable project to your project .

next under layout folder create following xml files and include following code in those xml files as follows.

activity_main.xml:

item_image.xml:

<?xml version="1.0" encoding="utf-8"?>
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scaleType="fitCenter" />

item_text.xml:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="16dp"
    android:textAppearance="?android:textAppearanceLarge"
    android:lineSpacingMultiplier="1.1"
    android:gravity="center" />

sample_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/intro_message"
        android:padding="16dp"
        android:textAppearance="?android:textAppearanceMedium"
        android:lineSpacingMultiplier="1.1"
        android:background="#fb3" />

ActionBarCompat Basic Example

Download eclipse project here : ActionBarCompatBasic.zip

After importing or creating project you need to add support_v7 library.

<![CDATA[


            This sample shows you how to use ActionBarCompat to create a basic Activity which
            displays action items. It covers inflating items from a menu resource, as well as adding
            an item in code. Items that are not shown as action items on the Action Bar are
            displayed in the action bar overflow.


        ]]>
    </string>

</resources>

Create ids.xml under values folder and include following code:

ids.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>


<item name="menu_location" type="id"/>

</resources>

Styles.xml:

template-dimens.xml:

<resources>

    

    <dimen name="margin_tiny">4dp</dimen>
    <dimen name="margin_small">8dp</dimen>
    <dimen name="margin_medium">16dp</dimen>
    <dimen name="margin_large">32dp</dimen>
    <dimen name="margin_huge">64dp</dimen>

    

    <dimen name="horizontal_page_margin">@dimen/margin_medium</dimen>
    <dimen name="vertical_page_margin">@dimen/margin_medium</dimen>

        <item name="android:shadowDy">-3.5</item>
        <item name="android:shadowRadius">2</item>

Create menu folder under res folder and create main.xml under menu folder and include following code:

main.xml:

<?xml version="1.0" encoding="utf-8"?>
