Question

I have problem with displaying data in my listview. it’s not displaying vertically.

here’s my code:

private ListView lv;
private ArrayList<String> results = new ArrayList<String>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.meal_result);
    BreakFastLog info = new BreakFastLog(this);
    info.open();

    String data1 = info.getMealNameData();
    //String data2 = info.getServingData();

    results.add(data1);
    lv = (ListView) findViewById (R.id.lvBF);   
    lv.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, results));
    lv.setTextFilterEnabled(true); 

    info.close();
}

and my xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >



    <ListView
        android:id="@+id/lvBF"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />


</LinearLayout>

What’s wrong with this? please help me figure out what makes it displayed horizontally.

Here’s the screenshot:

After gone through your code,

You have a only one String value String data1 = info.getMealNameData();
in your ArrayList<String> results. And results is added to your List Adapter.

So only one row displayed in your ListView.

So You have to either make a String[] for all user Inputs instead of your one String data1 and pass that String[] to your List Adapter.

Update:

String data1 = info.getMealNameData();
String[] inputData = data1.split(" ");
lv.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1, inputData ));
