Try this

CheckBox cb = (CheckBox)findViewById(R.id.checkBox);
if (cb.isChecked()) {
    // code to run when checked
} else {
    // code to run when unchecked
}

Boolean cBox1;

SharedPreferences pref =   getApplicationContext().getSharedPreferences("MyPref", 0); 

        cBox1=pref.getBoolean("check1", false);

            //Rb1.setChecked(true);
        }

                SharedPreferences.Editor editor = pref.edit();

                if(mchk1.isChecked() ){

                    editor.putBoolean("check1", true);

Make changes in your activity as below,

public class Setting extends ActionBarActivity implements CompoundButton.OnCheckedChangeListener {

CheckBox myCheckBox;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_setting);

    myCheckBox = findViewById(R.id.checkBox);
    myCheckBox.setOnCheckedChangeListener(this);
}

@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
    if(isChecked){
        //here the checkBox is checked
    }else {
        //here the checkBox is not checked
    }        
}
}

Let me know if it works...
