问题在这里我无法使用MainActivity.java中的.getStringExtra获取待处理的意图值我每次都得到null

我不是一个机器人，所以如果我犯了任何愚蠢的错误，请不要判断我

Answer 1

你的问题在这里：

intent.putExtra("url",true);

您添加了＆＃34;额外＆＃34;用钥匙＆＃34; url＆＃34;和价值＆＃34;真＆＃34;。这是boolean。如果您致电getStringExtra("url")，您将获得null。如果你调用``getBooleanExtra（＆＃34; url＆＃34;）you will get为真。

也...

你绝对不能这样做（在showNotification()中）：

    MainActivity ctsx = new MainActivity();

只有Android才能实例化Android组件（Service，Activity等。）。

如果您需要Context，则需要将其传递给您的方法。
