以编程方式更改android:enabled ="true"

Question

首先,我的应用程序将首选项设置为"true"关于checkboxpreference.现在我需要以编程方式设置此值(android:enabled ="true")或false.任何的想法？

protected void checkLicense(){
        PackageManager manager = getPackageManager();
        if (manager.checkSignatures("core.package.name", "key.package.name")
            == PackageManager.SIGNATURE_MATCH) {
            //full version
            isEnabled = true;
            Toast.makeText(this, "pro", Toast.LENGTH_LONG).show();
        }
        else {
            Toast.makeText(this, "free", Toast.LENGTH_LONG).show();
            isEnabled = false;




<CheckBoxPreference
                        android:enabled="true"
                        android:title="Now"
                        android:defaultValue="false"
                        android:key="keep" />
