Populating listview from arraylist

Question

I want to populate a list view with an array list. The array list is fetched from a soap web service response.
I have used it as following:

mylistview = (ListView)findViewById(R.id.list);

listAdapter = new ArrayAdapter<Plant>(MainActivity.this,
             android.R.layout.simple_list_item_1, array_books);
mylistview.setAdapter(listAdapter);

It display following in list view:

Book{id=1; name= C++; imagepath=https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GW3ixVIGHLrrXb2yN_6i;}

Book{id=2; name= Java; imagepath=https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GW3ixVyN_6i;}

Book{id=3; name=Android; imagepath=https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GW3HLrrXb2yN_6i;}

I want to display the image by retrieving it from its path in Image View and display only name of book like: image ................ Java

When I change the layout in

listAdapter = new ArrayAdapter<Book>(MainActivity.this,
                 android.R.layout.row, array_books);

it gives error that row cannot resolved as a resource. But row.xml is present in the layout folder. How can I correct this error and display the items I want in the list view?

Try to change android.R.layout.row to R.layout.row

Try this

listAdapter = new ArrayAdapter<Plant>(MainActivity.this,
            R.layout.row, array_books);// Change  android.R.layout.row to R.layout.row

Your row is present in your layout so need to find using R.layout.row

It worked. And how to get only particular part of array list like only book name.??

@user3823856 you need override toString() method on Plant class then return anything you want like " return title; "

@user3823856 I didn't get you. What are you talking about?

@user3823856 use a custom adapter in that case.

Use R.layout.row instead of android.R.layout.row

As @Giru pointed out, if your xml file row.xml is in your layout folder, you can't reference it by android.R

The android.R object has references to the resources bundled with Android.

Your resources are simply under your.package.R so in your file just remove the "android." and have

listAdapter = new ArrayAdapter<Plant>(MainActivity.this,
            R.layout.row, array_books);

and you should be good to go.
