Android Call Intent Permission

Question

我正在尝试在我的应用程序中实现一个调用函数我有以下代码：

Intent phoneCall = new Intent(Intent.ACTION_CALL);
phoneCall.setData(Uri.parse("123456"));
startActivity(phoneCall);

我在清单文件中添加了所需的权限，但它仍然给我以下错误：

Call requires permission which may be rejected by user: code should explicitly check to see if permission is available (with `checkPermission`) or explicitly handle a potential `SecurityException` less... (Ctrl+F1) 
This inspection looks at Android API calls and ensures that the correct type of resource is passed to an int-parameter expecting resources of a given type; it checks that APIs which expect an RGB color integer are passed actual colors rather than color resources; it checks that APIs which require a certain permission have the permission declared in the manifest; it checks that parameters expected to fall within a given range actually do; it checks that results of certain method calls are looked at by the caller, and so on.

你知道我怎么解决这个问题：//

由于您的Target Sdk版本为23，因此您需要在运行时询问用户权限。虽然您仍需要在Manifest.xml中包含权限。

        if (ContextCompat.checkSelfPermission(this,
                Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(new String[]{Manifest.permission.CALL_PHONE},
                    REQUEST_CODE_ASK_PERMISSIONS);
        } else {
            Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "your number"));
            startActivity(intent);
        }


@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    switch (requestCode) {
        case REQUEST_CODE_ASK_PERMISSIONS:
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                Toast.makeText(this, "Call Permission Granted..Please dial again.", Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(this, "Call permission not granted", Toast.LENGTH_SHORT).show();
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}
