Android:Passing a hash map between Activities

Question

I have a map between string and a class object. I populate this map in Activity1 and i would like to pass it to activity2.

public class NEW extends Activity         


        

Answer 1

Create a new java file which will be global for whole application.

Step1:

public class GlobalClass extends android.app.Application 
{
 public static Map data_map = new Map();
}

Step2:

After doing that, Register this "GlobalClass" in AndroidManifest.xml

Step3:

now you can use this Map anywhere in your application.

@Override
protected void onCreate(Bundle icicle)
{
 GlobalClass global = (GlobalClass)getApplication();
 Map my_map_data = global.data_map;
}

These steps maybe helpful for you...
