我想在 Adapter 中运行新的 Activity 使用动画，但是我有一些错误

在我的代码底部，我不知道它不起作用

holder.newsItem.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                if(isOnline()) {
                    Intent i = new Intent();
                    i.setClass(getContext(), NewsDetali.class);
                    i.putExtra("id", ArrayListNews.get(position).getId());
                    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(i);

//error this line
                    ((Activity) context).overridePendingTransition(R.anim.pull_in_left, R.anim.push_out_right);

                } else {
                    Toast.makeText(getContext(), "Отсутствует подключение к интернету", Toast.LENGTH_LONG).show();
                }
            }
        });

更新:

所有代码

public class NewsAdapter extends ArrayAdapter<NewsObject>{
    ArrayList<NewsObject> ArrayListNews;
    int Resourse;
    Context context;

    private ImageLoader imageLoader;

    @Override

        }


        imageLoader.displayImage(ArrayListNews.get(position).getImageLink(), holder.imageNews, null, new ImageLoadingListener() {

                int color = Color.parseColor("#4D000000"); //The color u want             
                holder.imageNews.setColorFilter(color);
                holder.nameNews.setText(ArrayListNews.get(position).getName());
                holder.dateNews.setText(ArrayListNews.get(position).getDate());
            }

            @Override

                Log.e("Script", "OnLoadeingStarted");

        }, new ImageLoadingProgressListener() {
            @Override

                Log.e("Script", "OnProgressUpdate" + uri + " " + total);
            }
        });




        holder.newsItem.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                    Intent i = new Intent(getContext(), NewsDetali.class);

                    i.putExtra("id", ArrayListNews.get(position).getId());
                    i.putExtra("title", ArrayListNews.get(position).getName());
                    i.putExtra("image", ArrayListNews.get(position).getImageLink());
                    i.putExtra("description", ArrayListNews.get(position).getDescription());
                    i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

                    context.startActivity(i);


                    //danger line!!! Error this
                    overridePendingTransition(R.anim.pull_in_left, R.anim.push_out_right);

            }
        });

        return convertView;
    }


    static class ViewHolder {
        public ImageView imageNews;
        public TextView nameNews;
        public TextView dateNews;
        public RelativeLayout newsItem;
        public PlayGifView loadImg;
    }



}

最佳答案

这可能有帮助

Activity activity = (Activity) context;
activity.startActivity(intent);
activity.overridePendingTransition(R.anim.act_start_in_from_right, R.anim.act_start_out_to_left);

关于java - overridePendingTransition 不适用于适配器 (android)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/30931866/
