Question

I have multiple activities in which I want to use same code in those activity.
I finished it with having same bunch of code in each activity.
How can minimize this redundant code.
For doing this I dont want to create object and use it’s methods for removing redundancy…

Plz help…
Thank U….

Answer 1

the solution is simple: extends the class Activity, and add him all the methods you want.
(I usually call this class BaseActivity for instance)
then, when you are developing new activity – instead of extend the class Activity – extends the class BaseActivity you’ve made, which contain the methods you added..

public class BaseActivity extends Activity
{
protected int mSomeValue;

protected void someMethod1()
{

}

protected void someMethod2()
{

}

protected void someMethod3()
{

}

}

class SomeActivity extends BaseActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    someMethod1();
}
}

class SomeActivity2 extends BaseActivity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    someMethod1();
}
}
