1 つのクラスを作成し、それを ListView :: で拡張します
public class MyCustomListView extends ListView
{
private Bitmap background;
public MyCustomListView(Context context, AttributeSet attrs)
{
super(context, attrs);
background = BitmapFactory.decodeResource(getResources(), R.drawable.yourImage);//yourImage means your listView Background which you want to move
}
@Override
protected void dispatchDraw(Canvas canvas)
{
int count = getChildCount();
int top = count > 0 ? getChildAt(0).getTop() : 0;
int backgroundWidth = background.getWidth();
int backgroundHeight = background.getHeight();
int width = getWidth();
int height = getHeight();
for (int y = top; y < height; y += backgroundHeight)
{
for (int x = 0; x < width; x += backgroundWidth)
{
canvas.drawBitmap(background, x, y, null);
}
}
super.dispatchDraw(canvas);
}
}
XMLファイルで、次のようなリストビューを1つ取得します::
//要件に応じて他の属性を設定します
<com.test.MyCustomListView
android:id="@+id/listview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
</com.test.MyCustomListView>
