Question

I created a file in \res\layout named contactlist.xml

But it is not recognized in my code:

SimpleCursorAdapter mAdapter = new SimpleCursorAdapter(this,
        //android.R.layout.simple_list_item_1, mContacts, //if cre8 own layout, replace "simple_[etc]"
        //android.R.layout.simple_list_item_checked, mContacts, // or simple_list_item_multiple_choice
        //android.R.layout.simple_list_item_multiple_choice, mContacts,
        android.R.layout.contactlist, mContacts, // <- contact list ist xml-non-grata
        new String[] { ContactsContract.Contacts.DISPLAY_NAME },
        new int[] { android.R.id.text1 });

I want to create a custom layout that for each Contact has three checkboxes.

Why is my custom layout not accepted as valid?

I finally got it working; as usual, it’s not that tough once you grok a couple of concepts. It boils down to using this sort of code, which I begged/borrowed/stole and adapted:

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

// Return all contacts, ordered by name
String[] projection = new String[] { ContactsContract.Contacts._ID,
        ContactsContract.Contacts.DISPLAY_NAME }; 
mContacts = managedQuery(ContactsContract.Contacts.CONTENT_URI,
        projection, null, null, ContactsContract.Contacts.DISPLAY_NAME);

// Display all contacts in a ListView
SimpleCursorAdapter mAdapter = new SimpleCursorAdapter(this,
        R.layout.ondemandandautomatic_authorize, mContacts,
        new String[] { ContactsContract.Contacts.DISPLAY_NAME },
        new int[] { R.id.contactLabel });

setListAdapter(mAdapter);

}

…and making sure “ondemandandautomatic_authorize” (or whatever you name your layout file) is something like this (unfinished, but you get the idea):

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

    <CheckBox
        android:id="@+id/checkBox1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="1" />

        <CheckBox
        android:id="@+id/checkBox2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="2" />

        <CheckBox
        android:id="@+id/checkBox3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="3" />

    <TextView
        android:id="@+id/contactLabel"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="(replace this)"
        android:textSize="20px" >
    </TextView>

</LinearLayout>

…and that “R.id.contactLabel” is replaced with “R.id.”

There’s more to be done, obviously, but a big obstacle has been hurdled.

Answer 1

It should be

R.layout.contactlist

and not

android.R.layout.contactlist

android is used when you are using the system resources.
