So I have been working on a project app that reads from a database and prints the contents of the DB into a list view. I now want to print more then just one column, I want to add two buttons and an edittext to the row that is being printed. I have created the new xml file that I want to use but when i try to set the new layout to be this xml file it doesnt work. Can anyone explain or show me how to fix my problem?
This is the XML layout I want to use for each row
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView android:id="@+id/item1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="30sp"
android:paddingBottom="5dp"
android:hint="@string/hint"/>
<Button
android:id="@+id/plusButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/plusButton"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<EditText
android:id="@+id/edit1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="@string/hint"
android:layout_alignParentTop="true"
android:layout_toLeftOf="@+id/minusButton"
android:layout_toStartOf="@+id/minusButton"
android:layout_marginRight="30dp" />
<Button
android:id="@+id/minusButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/minusButton"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>
And this is the class where I am displaying the contents of the SQLite database, the error occurs on line 100 when i try to change the android.R.layout to the row.xml file
