Question

我正在我的应用程序中实现运行时权限，但我无法显示CALL_PHONE的权限。我需要显示两个权限，read_contact和call_phone。我可以完美地显示read_contact但不能显示call_phone权限。

我正在使用AVD模拟器进行测试。

一些帮助将是apreciate！

这是我的代码：

      callPesmission.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                requestCallPhonePermission();
            }
        });

        contactPesmission.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                requestContactsPermission();
            }
        });


 private void requestContactsPermission() {
        String locationPermission = Manifest.permission.READ_CONTACTS;
        int hasPermission = ContextCompat.checkSelfPermission(getActivity(), locationPermission);
        String[] permissions = new String[] { locationPermission };
        if (hasPermission != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(permissions, REQUEST_CONTACTS);
        } else {
            Toast.makeText(getActivity(), "We already have persmission", Toast.LENGTH_SHORT).show();
        }
    }

    private void requestCallPhonePermission() {
        String callPermission = Manifest.permission.CALL_PHONE;
        int hasPermission = ContextCompat.checkSelfPermission(getActivity(), callPermission);
        String[] permissions = new String[] { callPermission };
        if (hasPermission != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(permissions, REQUEST_CALL_PHONE);
        } else {
            Toast.makeText(getActivity(), "We already have persmission", Toast.LENGTH_SHORT).show();
        }
    }

@Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        switch (requestCode) {
            case REQUEST_CONTACTS:
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    Toast.makeText(getActivity(), "READ_CONTACTS GRANTED", Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(getActivity(), "READ_CONTACTS DENIED", Toast.LENGTH_SHORT).show();
                }
                break;
            case REQUEST_CALL_PHONE:
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    Toast.makeText(getActivity(), "CALL_PHONE GRANTED", Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(getActivity(), "CALL_PHONE DENIED", Toast.LENGTH_SHORT).show();
                }
                break;
            default:
                super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }

Answer 1

我认为你的代码没有任何问题，

确认它是否确实存在于manifest.xml中。

Dialog不会显示它是否存在于清单中，如果我们尝试使用该功能，则可能会抛出安全异常

Answer 2

我忘了在清单中添加权限.....

<uses-permission android:name="android.permission.CALL_PHONE" />

Answer 3

添加此

private static final int PHONE_CALL_REQUEST=0;

和您的按钮

if (ContextCompat.checkSelfPermission(MainActivity.this, android.Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED)
{
    ActivityCompat.requestPermissions(MainActivity.this, new String[]{android.Manifest.permission.CALL_PHONE},PHONE_CALL_REQUEST);
}
else
{
    Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "+01723915447"));
    startActivity(intent);
}

Answer 4

步骤1：

 <uses-permission android:name="android.permission.CALL_PHONE" />

第2步：

<permission
    android:name="mypackage.permission.CALL_PHONE"
    android:protectionLevel="signature" />

NB：：步骤2中的 mypackage 是您的根项目软件包名称，例如com.myapp，因此步骤2中的上述内容将变为

<permission
    android:name="com.myapp.permission.CALL_PHONE"
    android:protectionLevel="signature" />

最后一步：在您的Java / Kotin函数中，Manifest.permission.CALL_PHONE将可用

Answer 5

在奥利奥使用，

android.Manifest.permission.CALL_PHONE

您忘记了android.部分。

我无法在运行时权限中显示Manifest.permission.CALL_PHONE
