Адаптер массива Загрузка изображений из папки Res (приложение для Android)
Я новичок Android. Я пытаюсь загрузить кучу изображений из моей папки res / Drawable в Gridview через адаптер массива. к сожалению, мое приложение вылетает каждый раз, когда я пытаюсь просмотреть активность с помощью gridView. я хотел бы знать, как установить imageResource изображения, которое у меня есть в папке res для отображения в Gridview
вот мой код:
Smile.class
public class Smiley extends Activity {
GridView gridView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.smile);
gridView = (GridView) findViewById(R.id.gridView1);
String planets[] = this.getResources().getStringArray(R.array.imageme);
ArrayAdapter<String>adapter = new ArrayAdapter<String> (this,R.layout.grid_view_row,R.id.imageGrid , planets);
gridView.setAdapter(adapter);
}
}
Smile.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

<GridView

android:horizontalSpacing="10dp"

</GridView>
</RelativeLayout>
grid_view_row.xml (пользовательский макет для Gridview)

android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="2dp"
android:src="@drawable/a"

</FrameLayout>
My String Array (xml)
