use

String gen= bundle.getString("gen");

instead of

String gen= bundle.getString("Extra_gen");

for retrieving selected RadioButton Value from Intent sended from previous Activity. because you are sending RadioButton Value with gen key but trying to retrieve it using Extra_gen

The key should be the same

      i.putExtra("gen", gen);

Its

   String gen= bundle.getString("Extra_gen");

should be

   String gen= bundle.getString("gen");

Edit:

You are using getApplicationContext(). Instead use a activity context

    Toast.makeText(getApplicationContext(), "Please accept it", 1).show();

To know when to use application context and when to use activity context, check the answer by commonsware in the below link

When to call activity context OR application context?

    Toast.makeText(act1.this, "Please accept it", 1).show();

Use

String gen= bundle.getString("gen");

You need something like this

rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
     void onCheckedChanged(RadioGroup rg, int checkedId) {
          for(int i=0; i<rg.getChildCount(); i++) {
               RadioButton btn = (RadioButton) rg.getChildAt(i);
               if(btn.getId() == checkedId) {
                    String text = btn.getText();
                    // do something with text
                    return;
               }
          }
     }
});

(OR)

When you need to get the selected radio option.

int id = rg.getCheckedRadioButtonId();
if (id == -1){
     //no item selected
}
else{
if (id == R.id.radio_button1){
    //Do something with the button
}
}

use setOnCheckedChangeListener for radioGroup.

Sample code for RadioGroup which contains two RadioButtons

radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        public void onCheckedChanged(RadioGroup arg0, int arg1) {

            radioButton = (RadioButton) findViewById(radioGroup
                    .getCheckedRadioButtonId());
            if (radioButton.getText().equals("Name")) {
                // code for first radioButton
            } else {
                // code for second radioButton                  
            }
        }
    });

I hope this will help you.

int radioButtonID = rg.getCheckedRadioButtonId();
View radioButton = rg.findViewById(radioButtonID);
int index = rg.indexOfChild(radioButton);
String gen="male";

if(index==0)
gen="male";
else
gen="female";

....

i.putExtra("gen", gen);
startActivity(i);

Make sure that in your activity_main.xml male is having index 0.
