Customizing EditText

Under res folder create new folder called drawable .
Under drawable folder create new XML file called box_edittext

Under box_edittext.xml file include following code
box_edittext.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:padding="10dp"
    android:shape="rectangle" >

    <solid android:color="#FFFFFF" />

    <corners
        android:bottomLeftRadius="5dp"
        android:bottomRightRadius="5dp"
        android:topLeftRadius="5dp"
        android:topRightRadius="5dp" />

</shape>

Whenever you want to customize the EditText just call background property and call box_edittext from drawable folder as follows
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"
    android:background="#cccccc" >

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="35dp"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="40dp"
        android:background="@drawable/box_edittext"
        android:ems="10"
        android:hint="enter name"
        android:inputType="textPersonName"
        android:paddingLeft="5dp" >

        <requestFocus />
    </EditText>

</RelativeLayou

Actionbar Tutorials Part 07----Navigating with the App Icon

ScreenShots:

-->Here I'm creating two activity called MainActivity and AnotherActivity

-->From MainActivity we are navigating to AnotherActivity and from AnotherActivity we are           
     navigation back with action bar app icon. Below you can find that two activities and you need
    to do some code in AndroidManifest file under AnotherActivity tag.

activity_main.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.ram.navigatingupwiththeappicon.MainActivity"
    tools:ignore="MergeRootFrame" >

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="108dp"
        android:onClick="openAnotherActivity"
        android:text="Open AnotherActivity" />

</RelativeLayout>

anotheractivity.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" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="This is Another Activity"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</LinearLayout>

    }

    public void openAnotherActivity(View v) {

        startActivity(new Intent(getApplicationContext(), AnotherActivity.class));
    }
}

AnotherActivity.java:

public class AnotherActivity extends Activity {
    @Override

Navigation Drawer example in Android

ScreenShots:

download following  icon and store it in drawable folder from here:

Insert following tags in activity_main.xml layout:
activity_main.xml:
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <!-- The main content view -->

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    <!-- The navigation drawer -->

    <ListView
        android:id="@+id/left_drawer"
        android:layout_width="200dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#ffffff"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        />

</android.support.v4.widget.DrawerLayout>

Create new xml file called text(text.xml) and insert following tags:
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="wrap_content"
