Question

I’m a PHP Web Developer. When I create a view article page I was passing the id in GET something like article.php?id=10

But now in android if I have an activity which views the article, how to pass to it the article ID to select it’s data from the database?

What is my best option?

Answer 1

You have to pass the article id in the intent when calling the ArticleActivity. Here is how to do it:

Intent intent = new Intent(this, ArticleActivity.class);
intent.putExtra("articleId", articleId);
startActivity(intent);

In this code, this is the context of your current activity; articleId is your articleId you want to pass. Then, when you want to retrieve it in the ArticleActivity, you do this in onCreate of the activity:

Bundle extras = getIntent().getExtras();
int articleId = extras.getInt("articleId");

Thats it! Hope that helped.
