Resources$NotFoundException: Resource ID # type #0x12 is not valid

问题

Tell me please, why it doesn't like my layout (RelativeLayout with @+id/row)?

When I use it with self created adapter (layoutinflater) it works good. And one more. I plan to use in my database bitmaps, stored like byte[]. Can SimpleCursorAdapter itself convert byte[] dates in to image (ImageView) or does it work only with texts?

Error description

android.content.res.Resources$NotFoundException: Resource ID #0x7f0c006c type #0x12 is not valid

MainActivity

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    mListView = ( (ListView) findViewById (R.id.notes_listView) );
    mNoteDb = new NoteDb (getApplicationContext ());
    Cursor c = mNoteDb.getTitleColumn ();

    SimpleCursorAdapter mAdapter = new SimpleCursorAdapter (getApplicationContext (),
            R.id.row, // **<<< THIS ONE**
            c, new String[]{NoteDb.MainTable.COLUMN_TITLE}, new int[]{R.id.title_text_row}, 0);
    mListView.setAdapter (mAdapter);

row layout

<RelativeLayout
android:id="@+id/row"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

Cursor query

public Cursor getTitleColumn () {
    SQLiteDatabase db;
    db = mNoteDbOpenHelper.getReadableDatabase ();
    Cursor c = db.query (MainTable.TABLE_NAME,
            new String[] {MainTable._ID, MainTable.COLUMN_TITLE},
            null, null, null, null, null);
    return c;

回答1:

you should provide a layout not an id. Replace R.id.row with R.layout.your_layout_name

回答2:

I really bet you trying to textView.setText(Integer) somewhere.

Han, didn't read question fully. Update

No, you can't place pictures in default adapter. It works only with text. You need to create your own Adapter. And I recommend you to switch to RecyclerView especially with displaying pictures,
