permissioncontroller权限申请的弹框可以调整字体吗？代码在哪里

可以调整权限申请弹框的字体大小，可以通过设置系统的字体大小来实现。而权限申请弹框的代码具体在哪里，需要看您使用的具体框架或者库。在 Android 系统中，权限申请弹框通常是通过系统 API 实现的，可以通过以下代码来请求权限：

if (ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.READ_CONTACTS) != PackageManager.PERMISSION_GRANTED) {
    // Permission is not granted
    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity, Manifest.permission.READ_CONTACTS)) {
        // Show an explanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.
    } else {
        // No explanation needed; request the permission
        ActivityCompat.requestPermissions(thisActivity, new String[]{Manifest.permission.READ_CONTACTS}, MY_PERMISSIONS_REQUEST_READ_CONTACTS);

        // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
        // app-defined int constant. The callback method gets the
        // result of the request.
    }
} else {
    // Permission has already been granted
}

您可以在 `shouldShowRequestPermissionRationale` 方法的回调中自定义弹框样式，包括字体大小等。
