In Java, How Do I Simplify My Code Using Inheritance? (android Dev.)

In various activities I have very similar methods. For example: @Override public void onClick(View v) { switch (v.getId()) { case R.id.ibHome: Intent menuIntent =

Solution 1:

You could use inheritance, but that actually may not be the best choice, especially if the two activities are not directly related in an "Is-A" relationship.

In this case, you're probably better off declaring a new class that implements OnClickListener interface. You can then instantiate that class and bind it to your buttons' click events wherever they're used.

Here's an example:

publicclassHomeButtonHandlerimplementsOnClickListener{

        @OverridepublicvoidonClick(View v) {
            IntentmenuIntent=newIntent(v.getContext(),Menu.class);
            v.getContext().startActivity(menuIntent);            

        }

    }

And in your activities, you can just bind the HomeButtonHandler to the onClickListner of the button:

homeButton.setOnClickListener(newHomeButtonHandler());

Solution 2:

Create a common BaseActivity for all your activities, then override only the BaseActivity.onClick() method.

In this way you will have a single switch for all your activities.
