Android Gallery仅限文字

Fai*_*bid 5 android gallery

我研究了API演示,他们有一个画廊示例,其中仅显示文本,代码仅使用Cursor,但是我想使用String数组。我如何才能使用它?这是API演示中的示例代码:

        Cursor c = getContentResolver().query(People.CONTENT_URI, null, null, null, null);
    startManagingCursor(c);

    SpinnerAdapter adapter = new SimpleCursorAdapter(this,
    // Use a template that displays a text view
            android.R.layout.simple_gallery_item,
            // Give the cursor to the list adatper
            c,
            // Map the NAME column in the people database to...
            new String[] {People.NAME},
            // The "text1" view defined in the XML template
            new int[] { android.R.id.text1 });

如果您只想显示静态的String对象列表,则ArrayAdapter应该执行以下操作:

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_gallery_item, new String[] {People.NAME});

但是,如果希望以后可以将更多String对象添加到列表中,则应使用List

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_gallery_item, new ArrayList<String>());
