Android :some serious work :P

hello pancakes !!  this is my first post here hope you like me too as brijesh :)

so starting for the first app ..

• Open up new android application and continue as explained previously, if you get any problem with that check the procedure again here .

• After you complete with making g it you will get the starting screen .Up-till now everything is just as we previously did .hence forth the real work starts. we will be working on activity_main.xml first.

 

• On activity_main.xml we will automatically be having some content as shown below and for rest we will be adding  some other things too.

• EXPLAINING THE CODE 
  The first segment we have here is

  1.   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   2.   xmlns:tools="http://schemas.android.com/tools"
    3.  android:layout_width="match_parent"
   4.   android:layout_height="match_parent"
    5.  tools:context=".MainActivity" >

  1.   This line is default which actually import pacakages.
  2. This line defines the where to import the android tools.
  3. android:layout_width defines the width of our app on emulator.
  4. android:layout_height defines height of our app on emulator.
  5. This line defines where to start ie, MainActivity

  The second segment we have is 

        1.  <TextView
        2.    android:layout_width="wrap_content"
        3.  android:layout_height="wrap_content"
        4.  android:layout_centerHorizontal="true"
        5.  android:layout_centerVertical="true"
        6.  android:text="@string/hello_world" />

  1. It marks the beginning of Textview tag which actually contains the features about how things are to be arranged in text view
  2. the other tags are preety self explainatory , you may try on some of them yourself by deleting the values upto = and eclipse will come to your service.
  3. in last one android:text="@string/hello_world" we actually referenced the string hello world saved in values. in other places too we will be using the same .
     This was all for today we will get on with the more on xml on next post. Will be waiting for comments/ suggestions. :)
