如何在Android中使用解析器动态设置线性布局中的背景图像

Question

如何在Android中使用Parser在LinearLayout中动态设置背景图片。 请根据如何动态设置图像来帮助我。

private void createEventCoverPage() {
final EventCoverData currentEventData = mEventData.get(mCurrentIndex);
LinearLayout mParentLayout = (LinearLayout) findViewById(R.id.eventCoverParentLayoutId);
                mParentLayout.setBackground(new BitmapDrawable(getResources(),                        Picasso.with(getParent()).load(currentEventData.mImageSrc).get()));
 }      

@Parcel
public static class EventCoverData {
@SerializedName("src")
public String mImageSrc;
}

Answer 1

你可以用这样的东西

        Picasso.with(mContext).load(currentEventData.mImageSrc).into(new Target() {
            @Override
            public void onBitmapLoaded(Bitmap bitmap, Picasso.LoadedFrom from) {
                 mParentLayout.setBackground(new BitmapDrawable(getResources(),bitmap);
            }

            @Override
            public void onBitmapFailed(Drawable errorDrawable) {

            }

            @Override
            public void onPrepareLoad(Drawable placeHolderDrawable) {

            }
        });
