Question

我是android新手，我有两个活动，每个活动都包含一个循环视图。现在，当我点击我的第一个活动项目时，这将转到新活动并从第二个回收视图中获取结果，我需要在我的第一个回收视图中显示这个，我已经完成了所有这些，但我无法得到第二个回收视图的价值。我怎么能这样做？

这是我的代码的一部分

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

            Intent individual = new Intent(Context, `enter code here`A.class);`enter code here`
            individual.putExtra(Constants.REQ_TYPE,mCollectionDate);
            individual.putExtra(Constants.GROUP_POSITION,position);
            individual.putExtra(Constants.CENTER_POSITION,Selectedposition);
            individual.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            ((Activity)mContext).startActivityForResult(individual, 200);
            //mContext.startActivity(individual);

        }
    });
}

谢谢！

您必须在返回之前在第二个活动上设置结果：

Intent intent = new Intent();
intent.putExtra("parameter", response);
setResult(Activity.RESULT_OK, intent);
finish();

然后对第一项活动进行处理：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if ( requestCode == 200 && resultCode == Activity.RESULT_OK ) {
        <<YOUR PARAMETER>>  =  data.getExtra("parameter");

    }
}
