android - 资源 $NotFoundException : Resource ID # type #0x12 is not valid

Question

请告诉我，为什么它不喜欢我的布局(RelativeLayout with @+id/row)？

当我将它与自行创建的适配器 (layoutinflater) 一起使用时，效果很好。 还有一个。我计划在我的数据库中使用位图，像 byte[] 一样存储。 SimpleCursorAdapter 本身可以将 byte[] 日期转换为图像 (ImageView) 还是仅适用于文本？

错误描述

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

主 Activity

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);

行布局

<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"

    android:layout_alignParentRight="true"
    android:layout_marginRight="10sp"
    android:text="@string/main_row_tv_date"

游标查询

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;

您应该提供布局而不是 ID。将 R.id.row 替换为 R.layout.your_layout_name
