运行时权限对话框未显示Android 7.1

Question

我需要启动一个服务，它需要READ_PHONE_STATE权限。我声明了它并动态应用。回调函数已被重写。但是，虚拟机不会弹出请求权限的对话框。

代码如下。

AndroidManifest.xml中：

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

动态应用：

requestPermissions(new String[]{Manifest.permission.CALL_PHONE},1);

请帮我。 非常感谢。

使用以下函数检查onCreate（）方法中的运行时权限：

   checkPermission();
   requestPermission();

和功能是：

 private boolean checkPermission() {
    return ( ContextCompat.checkSelfPermission(getApplicationContext(), READ_PHONE_STATE ) == PackageManager.PERMISSION_GRANTED);
}

private void requestPermission() {
    ActivityCompat.requestPermissions(LoginActivity.this, new String[]{READ_PHONE_STATE}, REQUEST_SMS);
}

public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_SMS:
            if (grantResults.length > 0 &&  grantResults[0] == PackageManager.PERMISSION_GRANTED){
            }else {
                Toast.makeText(getApplicationContext(), "Permission Denied, You cannot access and sms", Toast.LENGTH_SHORT).show();
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                    if (shouldShowRequestPermissionRationale(READ_PHONE_STATE)) {
                        showMessageOKCancel("You need to allow access to both the permissions",
                                new DialogInterface.OnClickListener() {
                                    @Override
                                    public void onClick(DialogInterface dialog, int which) {
                                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
                                            requestPermissions(new String[]{READ_PHONE_STATE},
                                                    REQUEST_SMS);
                                        }
                                    }
                                });
                        return;
                    }
                }
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}

你应该用

 <uses-permission-sdk-23 android:name="android.permission.READ_PHONE_STATE" />

代替

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