java - Android 适配器的 getView() 不调用 Activity

Question

我正在尝试从适配器类中调用一个 Activity 。我的 Activity 类没有构造函数，只有 onCreate()。我如何从 getView() 中调用它？我搜索了解决方案，但没有用。

我的适配器 getView():

public View getView(int position, View convertView, ViewGroup parent) {
        //SharedPostView holder;
        PostActivity holder;



        if (convertView == null) {
            Log.d("network frag list"," convertView null ");
            LayoutInflater inflater = (LayoutInflater)
                    context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.activity_post, null);
            holder = new PostActivity();
            convertView.setTag(holder);
        } else {
            Log.d("network frag list"," convertView.getTag() ");
            holder = (PostActivity)convertView.getTag();
        }
        holder.init(position);
        Log.d("network frag list", " getView");


        return convertView;
}

如果我没理解错的话，您正试图从您的 ListView 启动另一个 Activity 。为此，您需要一个 Intent 。

Intent intent = new Intent(this, MySecondActivity.class);
startActivity(intent);
