Java Android应用程序锁库

我正在尝试在我的一个android应用程序中添加applock库。我希望在打开ShowContentActivity活动之前使用锁将其保护。我找到了一个很好的图书馆

我的ShowContentActivity的java代码如下所示

public void showContent(View view) {

        Intent intent = new Intent(LockActivity.this, ShowContentActivity.class);
    startActivity(intent);

    }

}

我已经按照图书馆页面上的说明执行了它。但我很困惑，无法使用。任何人请建议我如何创建锁并在打开活动前始终使用它

谢谢

我的全班同学如下

今天早上我看到了你的博客，并在那里回应了这一点（但我将在这里详细介绍一下）：

首先，提示用户在尝试锁定活动之前创建密码。如果他们没有创建PIN，那么他们就没有什么可解锁的：

new CreateLockDialogBuilder(Activity, 
    new LockCreationListener(){
        public void onLockCanceled(){ } // Dialog was closed without entry
        public void onLockSuccessful(){
            // They've created a PIN, so now you can use the unlocking mechanisms
            doSomethingOnAppLocked();
        }
    })
    .show();

锁定后，只需在showContent（View）方法的检查对话框中包装您的意图：

你是否在
