Java 如何等待用户在棉花糖中授予权限

我有一个应用程序，需要检查和请求多个权限（如果没有）。因此，当应用程序第一次运行时，它会跳过它之后的所有函数调用，即使在单击“允许访问”之后也是如此

if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
        != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    // Check Permissions Now
    ActivityCompat.requestPermissions(
            this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
            REQUEST_CODE_LOCATION);
}
// Will not be called the first time
functionCall()

---

有没有办法在用户点击allow access之前不调用该函数

您必须考虑

requestPermissions

类似

startActivityForResult

。它只是启动用户授予/拒绝权限的UI

if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)
        != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    // Check Permissions Now
    ActivityCompat.requestPermissions(
            this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
            REQUEST_CODE_LOCATION);
}
// Will not be called the first time
functionCall()

---

与onActivityResult类似，您必须覆盖onRequestPermissionsResult才能知道权限过程何时完成。您可以检查权限是被授予还是被拒绝，然后从那里执行您的逻辑。

我认为您应该参考这个。
