how sent integer parameter in intent

Question

I want to send int parameter in intent like this:

String textname = (String) dataItem.get("name");

Intent m = new Intent(list.this,main.class);
m.putExtra("name",textname);
m.putExtra("page",1);

startActivity(m);

and in main class I get that parameter

Intent intent = getIntent();
name = intent.getStringExtra("name");
page1 = Integer.parseInt(intent.getStringExtra("page"));

but when I run my code it force closes!!!

You should use getIntent().getIntExtra(name, defaultValue) instead of Integer.parseInt(intent.getStringExtra("page"));

Update:

int defaultValue = -1;// take any default value of your choice

String name = intent.getStringExtra("name");
int page1 = intent.getIntExtra("page", defaultValue);

@zahra if it helped, please accept it as answer... or it will remain unsolved :) – Mithun May 25 '15 at 20:34
what do you mean? are you not able to get `int` data with above method? – Mithun May 26 '15 at 08:38
i get tow parameter "page " and "textname" and i send these i think one of the parameter have problem and one of this is null but i dont know how solve that! – zahra May 26 '15 at 08:50
that is your implementation issue right? But if with above method you are able to get proper value for `"page" ` `int` extra, it is a valid answer... However, for each `extra` of `int`, `String`, etc data types you put as extra into `Bundle` of sending `Intent` you can get with corresponding API to pull those extras. Check for methods available as mentioned in http://developer.android.com/reference/android/content/Intent.html – Mithun May 26 '15 at 08:55

Activity A

String textname = (String) dataItem.get("name");
        Intent m = new Intent(list.this,main.class);
        m.putExtra("name",textname);
        m.putExtra("page",1);
        startActivity(m);

Activity B

    Intent intent = getIntent();
    name = intent.getStringExtra("name");
    int page = intent.getIntExtra("page", 0);

where 0 is the default value.
