示例1: onLongClick
import android.view.View; //导入方法依赖的package包/类
@Override
public boolean onLongClick(View view) {
// Find the position of the preview relative to the touch location.
WidgetImageView img = mWidgetCell.getWidgetView();
// If the ImageView doesn't have a drawable yet, the widget preview hasn't been loaded and
// we abort the drag.
if (img.getBitmap() == null) {
return false;
}
Rect bounds = img.getBitmapBounds();
bounds.offset(img.getLeft() - (int) mLastTouchPos.x, img.getTop() - (int) mLastTouchPos.y);
// Start home and pass the draw request params
PinItemDragListener listener = new PinItemDragListener(mRequest, bounds,
img.getBitmap().getWidth(), img.getWidth());
Intent homeIntent = new Intent(Intent.ACTION_MAIN)

// as the preview is handled internally by launcher.
