How to pass a string from activity to ListActivity in Android?

I want to pass a String from Activity to ListActivity in Android. When I use normal Activty to Activity String pass method it gives NullPointerException. Here is what I tried to do.

Activity

Intent intent = new Intent(CheckAvailability.this , ListAtmActivity.class);
intent.putExtra("key", b_name);
startActivity(intent);

And I tried to get this from my ListActivity as this.

String brName=getIntent().getExtras().getString("key");

This working fine for Activity. But It gives NUllPointerException when it use in ListActivity.

Please help me.

May be your variable b_name is null, To avoid NUllPointerException you can declare this variable like as

String b_name="";

If you variable is null then it will give NUllPointerException

Your code should work fine. As an alternative you could also use:

String brName=getIntent().getStringExtra("key");

try using Bundle, that will sort out your problem

Bundle d=new Bundle();
d.putString("KEY",Your_String); 
intent.putExtras(d);
startActivity(intent);

and now in the ListActivity

String Your_String_Variable = getIntent().getStringExtra("KEY");
