Question

i am curious how i go about using the

putExtra("something", something);

in a intent to a new activity inside my application,

Intent i = new Intent(getApplicationContext(), MainActivity.class);
i.putExtra("something", something)
startActivity(i);

I need to know how i would the sending and receiving end would look like, For Loading a specific layout file depending on what was sent via the putExtra in the intent.

So if i send the i.putExtra(“a”, a) on the receiving end, it would create a content view with R.layout.a_layout.xml

but if i sent i.putExtra(“b”, b) it would load R.layout.b_layout.xml

Any ideas?

One nifty way of doing this would be to say:

Intent i = new Intent(getApplicationContext(), MainActivity.class);
i.putExtra("layout", R.layout.a_layout.xml);

to send the correct layout to your new class. Then in the new class, you can use:

int layout = getIntent().getIntExtra("layout", R.layout.default_layout);
setContentView(layout);
