方法。
我搞不清楚我哪里做错了。请帮帮我
漏窗DecorView@60f300f[]这是最初添加的
- 如果对话框不是以前的
disclose（）
，则会出现上述异常
活动
结束
添加此部分
纠正

FingerprintManager.CryptoObject cryptoObject = new FingerprintManager.CryptoObject(cipher);
FingerprintHandler helper = new FingerprintHandler(this);
helper.startAuth(fingerprintManager, cryptoObject);

generateKey();

通常，当您的活动被销毁、完成、暂停等后试图显示对话框时，会发生此问题
一些解决方案：
- 检查您是否没有调用
alertDialog.show（）
在完成、暂停或销毁活动并尝试控制它的同一父作用域中
例如，您启动了另一个活动或流程，然后尝试显示有关当前活动的对话框
- 如果（！this.isFinishing（））{//show your dialog}
对于您的活动
在启动对话框之前，您还可以使用小技巧检查活动的状态：
@重写受保护的void onPause（）{isRunning=false；}
@重写受保护的void onResume（）{isRunning=true；}
