答案 0 :(得分：1)
初始化适配器中的上下文
public ArticleAdapter(Context context) {
layoutInflater = LayoutInflater.from(context);
volleySingleton = VolleySingleton.getInstance();
imageLoader = volleySingleton.getImageLoader();
volleySingleton = VolleySingleton.getInstance();
requestQueue = volleySingleton.getRequestQueue();
MySharedPreferences prefs = MySharedPreferences.getInstance(context, SESSION);
CompID = prefs.getString("CompID", "");
this.context=context;
}
并用此
替换你的onclickholder.share.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(final View v) {
FragmentManager fr = ((Activity)context).getFragmentManager();
ShareFragment msgDialog = new ShareFragment();
msgDialog.show(fr, "Dialog");
}
});
