End of the year with new Things (its Android !!! )


-Create a new android project. named it to Android_project
-open main.xml file
-take a button from the palette.you can change its properties by openning the properties window.
-save it.now you can see its id in R.java file.
-now open the Android_projectActivity.java file and type the code bellow..

                Button b = (Button) findViewById(R.id.button1);
        b.setOnClickListener(new OnClickListener() {                   //(ctrl+1 choose import)
                                               
                                                @Override
                                                public void onClick(View v) {
                                                                // TODO Auto-generated method stub
                                                                startActivity(new Intent(Android_projectActivity.this, Second.class));
                                                }
                                });

You can take some advantages by pressing ctrl+space, ctrl+1.



-Now create another class.select src folder. right click-> new -> class.
-Give the name of the class.I named it Second.In the Superclass click on the Browse... Type Activity -> Choose Activity - android.app


 
-Create xml file for the second activity
- Right click on Layout -> New ->Other->Android XML File


 
-Take a text attribute and change the text from properties…




-In the Manifest file add the line
<activity android:name=".Second"></activity>

-          In the Second.java class add the lines
@Override
protected void onCreate(Bundle savedInstanceState) {
      // TODO Auto-generated method stub
      super.onCreate(savedInstanceState);
      setContentView(R.layout.second);
}

setContentView(R.layout.second) This line of code show the contents of the xml file.
