Question

When I try print the values to a textfield they come out as [Ljava.lang.String;@405af10

try {
    JSONObject jObject = new JSONObject(byteArrayOutputStream.toString());

    JSONArray Monday = jObject.getJSONArray("Monday");

    String time = "";
    String module = "";
    String lecturer = "";

    listAdapter = new ArrayAdapter<String[]>(this, R.layout.simplerow);


    for (int i = 0; i < Monday.length(); i++) 
    {
        time = Monday.getJSONObject(i).getString("time");
        module = Monday.getJSONObject(i).getString("module");
        lecturer = Monday.getJSONObject(i).getString("lecturer");

        listAdapter.add(new String[] {time, module, lecturer});

    }
    mainListView.setAdapter(listAdapter);    

} catch (Exception e) {
    e.printStackTrace();
}

in the simplerow xml file I have

<TextView  xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/rowTextView" 
 android:layout_width="fill_parent" 
 android:layout_height="wrap_content"
 android:padding="10dp"
 android:textSize="16sp" >
</TextView>

So each time a time, module or lecturer is printed it should be in it’s own textview box., but it’s not working and I don’t know why or how to fix it.

Answer 1

It is most likely because your ArrayAdapter is set to accept in a String array (String []).

listAdapter = new ArrayAdapter<String[]>(this, R.layout.simplerow); //Parameterized for String []

Therefore you have a list of String arrays, which is basically equivalent to a 2D array.

This means, when the ArrayAdapter is setting the Text to the TextView you specified, it is calling toString() on the whole array object, hence the hashcode.

Consider making your own ArrayAdapter and override the getView() method so that it does what you want to do. There are plenty of tutorials online, such as this one.
