I have radio button for the user to choose if he/she wants to keep his/her account logged in.

How do I assign SharedPreferences on the radiobutton? Please I r开发者_如何学编程eally need help.

This should work ...

SharedPreferences pref = getSharedPreferences("preferencesName", MODE_PRIVATE);
final SharedPreferences.Editor prefEdit = pref.edit();

RadioButton radio = (RadioButton) findViewById(R.id.radio);
radio.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        prefEdit.putBoolean("booleanValue", isChecked).commit();
    }
});

the above code is for putting the value of radio button through shared preferences and for reading value of radio button whether it is checked or not , use the following code

SharedPreferences prefs = activity.getSharedPreferences("preferencesName", Activity.MODE_PRIVATE);
Boolean value= prefs.getBoolean(booleanValue, false);
