How to save the checkbox state? - android

Question

Ya there are plenty of questions and answers about this stuff in the net but i just can't figure out how to save the checkbox state using sharedpreference. Someone just help me with the coding part which i was not able to do.

ch = (CheckBox) findViewById(R.id.checkBox1);

    ch.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
        if(ch.isChecked())
                {
            Toast.makeText(getApplicationContext(), "Check", Toast.LENGTH_SHORT).show();
            }
        else
        {
            Toast.makeText(getApplicationContext(), "Uncheck", Toast.LENGTH_SHORT).show();
        }}
    });
    }

Just create SharedPrefrences and Add value using .putBoolean()

 if(ch.isChecked()){             

    SharedPreferences settings = getSharedPreferences(PREFRENCES_NAME, 0);
    settings.edit().putBoolean("check",true).commit();

}

I think answer you already knew, let me clear your way,

make a boolean field in table
set its value true when CheckBox is checked else false

Next time when you are loading the activity, just read the field value and set Checkbox's status accordingly.

if(ch.isChecked())
{
    SharedPreferences preferences = context.getSharedPreferences("prefs_name", Context.MODE_PRIVATE);
    preferences.edit().putBoolean("checked", True).commit();
}
