```java
private GraphQLRequest getPostWithCommentsRequest(String id) {
String document = "query getPost($id: ID!) { "
+ "getPost(id: $id) { "
+ "id "
+ "title "
+ "rating "
+ "status "
+ "comments { "
+ "items { "
+ "id "
+ "postID "
+ "content "
+ "} "
+ "} "
+ "} "
+ "}";
return new SimpleGraphQLRequest<>(
document,
Collections.singletonMap("id", id),
Post.class,
new GsonVariablesSerializer());
}
```
```kotlin
private fun getPostWithCommentsRequest(id: String): GraphQLRequest {
val document = ("query getPost(\$id: ID!) { "
+ "getPost(id: \$id) { "
+ "id "
+ "title "
+ "rating "
+ "status "
+ "comments { "
+ "items { "
+ "id "
+ "postID "
+ "content "
+ "} "
+ "} "
+ "} "
+ "}")
return SimpleGraphQLRequest(
document,
mapOf("id" to id),
Post::class.java,
GsonVariablesSerializer())
}
```
Then query for the Post:
```java
Amplify.API.query(getPostWithCommentsRequest("[POST_ID]"),
response -> Log.d("MyAmplifyApp", "response" + response),
error -> Log.e("MyAmplifyApp", "error" + error)
);
```
```kotlin
Amplify.API.query(getPostWithCommentsRequest("[POST_ID]"),
{ Log.d("MyAmplifyApp", "Response = $it") },
{ Log.e("MyAmplifyApp", "Error!", it) }
)
```
```kotlin
try {
val response = Amplify.API.query(getPostWithCommentsRequest("[POST_ID]"))
Log.d("MyAmplifyApp", "Query response = $response")
} catch (error: ApiException) {
Log.e("MyAmplifyApp", "Query error", error)
}
```
