我在GraphRequest适配器的ListView中为Facebook发布评论计数getView()。这是我的代码
public class FeedListAdapter extends BaseAdapter {
.
.
.
@Override
public int getCount() {
return feedItems.size();
}
@Override
public Object getItem(int location) {
return feedItems.get(location);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
.
.
.
requestComments(feedItems.get(position).getObjectId(), viewHolder.tvPostCommentCount);
}
private void requestComments(String objectId, final TextView textViewCommentCount) {
Bundle parameters = new Bundle();
parameters.putString("filter", "toplevel");
parameters.putString("summary", "true");
new GraphRequest(
AccessToken.getCurrentAccessToken(),
"/"+objectId+"/comments?limit=3",
parameters,
HttpMethod.GET,
new GraphRequest.Callback() {
public void onCompleted(GraphResponse response) {
LOGMSG.SHOW(TAG+"requestComments() -> onCompleted()");
try {
JSONObject responseJsonObject = response.getJSONObject();
LOGMSG.SHOW(TAG+"requestComments() -> responseJsonObject:"+responseJsonObject);
JSONObject summaryJsonObject = responseJsonObject.getJSONObject("summary");
LOGMSG.SHOW(TAG+"requestComments() -> summaryJsonObject:"+summaryJsonObject);
textViewCommentCount.setText(NumberUtils.kFormatter(summaryJsonObject.getLong("total_count")));
}catch (Exception e) {
e.printStackTrace();
}
}
}
).executeAsync();
}
}
随着GraphRequest的号码调用增加，应用程序会因为最大活动线程数而崩溃。
这是Log

现在我的问题是如何调用GraphRequst以允许并行线程执行，以避免上述问题。
非常感谢您的回复。

我认为你正在以错误的方式实现它。我提供了一个代码plz检查它可能会起作用，因为在我的情况下它可以正常工作。
FacebookCallback<LoginResult> mCallBack=new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
// Facebook Email address
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
public void onCompleted(
JSONObject object,
GraphResponse response) {
Log.v("LoginActivity Response ", response.toString());
try {
Name = object.getString("name");
Email = object.getString("email");
Gender=object.getString("gender");
BD=object.getString("link");
}
catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,link,email");
request.setParameters(parameters);
request.executeAsync();
}
当你得到这个项目时，请在listView中使用它们。我希望这对你有所帮助。

问题在于您要定位的Android平台版本。你想要的是AsyncTasks由串行执行器处理，而不是并行执行器（如现在）。否则，一旦达到线程上限，你仍然会得到RejectedExecutionException。
