    <p>This is possibly a duplicate question.. please refer this <a href="https://stackoverflow.com/q/7045836/2219600" title="this text appears when you mouse over">link</a>.<br> I am able to map one json object to POJO.But how can i convert array of json object to pojo using the same jackson framework.</p> <pre><code>private void jsonToPojo(){ ObjectMapper mapper=new ObjectMapper(); try { User1 user1=mapper.readValue(readFromFile(), User1.class); User1[] user2=mapper.readValue(readFromFile(), User1[].class); System.out.println(user1); Toast.makeText(getApplicationContext(), "inside try", 0).show(); } catch (JsonParseException e) { // TODO Auto-generated catch block Log.i("Exception", "jsonparseexception"); e.printStackTrace(); } catch (JsonMappingException e) { // TODO Auto-generated catch block Log.i("Exception", "jsonmapping exception"); e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block Log.i("Exception", "ioexception"); e.printStackTrace(); } } </code></pre> <p>This is the class user object.</p> <pre><code>public class User { private int age = 23; private String name = "amal"; private List&lt;String&gt; messages = new ArrayList&lt;String&gt;() { { add("hi"); add("how"); add("are u."); } }; //getter and setter methods @Override public String toString() { return "User [age=" + age + ", name=" + name + ", " + "messages=" + messages + "]"; } </code></pre> <p>This is what i tried to do:(readFromFile() takes json from a file)</p> <pre><code>User1[] user2=mapper.readValue(readFromFile(), User1[].class); </code></pre> <p>The jsonToPojo() is working well for only one object. However, if i try the above line of code,its not taking the following json:</p> <pre><code>[ { "age":"23", "messages":["hi","how","are u."], "name":"amal" }, { "age":"98", "messages":["Reply","my","question"], "name":"You" } ] </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
