Android-适配器的内容已更改，但ListView未收到notification.content适配器未从后台线程修改

Question

我在修改列表视图时收到此异常。

  

适配器的内容已更改，但ListView未收到通知。内容适配器不会从后台线程修改。

但是我没有在后台线程上修改任何内容，而且我也没有经常这样做。只有在我有多个pns的情况下，如果设备进入睡眠模式，之后解锁时，应用程序点击列表视图会导致崩溃。

以下是我为在ListView中显示消息而编写的代码。

private class GetMessagesAsyncronousTask extends AsyncTask<Void, Void, Void> {
    private ProgressDialog myAsyncTask = null;

    @Override
    protected void onPreExecute() {

        myAsyncTask = new ProgressDialog(MessageActivity.this);
        myAsyncTask.setMessage(getString(R.string.msg_refresh_label));
        myAsyncTask.setIndeterminate(true);
        myAsyncTask.setCancelable(false);
        if (myAsyncTask != null && !myAsyncTask.isShowing()) {
            try {
                myAsyncTask.show();
            } catch (WindowManager.BadTokenException e) {
                e.printStackTrace();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

        super.onPreExecute();

    }

    @Override
    protected Void doInBackground(Void... params) {
        // Here i am calling the web services and inserting the data in DB.
        }

        return null;

    }

    @Override
    protected void onPostExecute(Void result) {
        super.onPostExecute(result);
        if (myAsyncTask != null && myAsyncTask.isShowing()) {
            try {
                myAsyncTask.dismiss();
                myAsyncTask = null;
            } catch (WindowManager.BadTokenException e1) {
                e1.printStackTrace();
            } catch (Exception e2) {
                e2.printStackTrace();
            }
        }
            // this method is for updating the messages Count in spinner and list view rows when push notification came.
            resetAdapter();
        }

    }
}

在ResetAdapter中，基于微调器选择，我在listview中显示相应的消息。

DropdownAdapter dropDownAdapter = new DropdownAdapter(
                MessageActivity.this, R.layout.row_dropdown_action,
                listNavigationArray);
        dropDownAdapter
                .setDropDownViewResource(android.R.layout.simple_dropdown_item_1line);
        getActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_LIST);
        getActionBar().setDisplayShowHomeEnabled(false);
        getActionBar().setDisplayShowTitleEnabled(false);
        ActionBar.OnNavigationListener navigationListener = new OnNavigationListener() {

            @Override
            public boolean onNavigationItemSelected(int itemPosition,
                    long itemId) {
                navigateToFolder(itemPosition);
                return false;
            }
        };
        getActionBar().setListNavigationCallbacks(dropDownAdapter,
                navigationListener);
    }

//导航文件夹方法。

    private void navigateToFolder(int itemPosition) {
            if (itemPosition == 2) {
            listView.setVisibility(View.GONE);
            archiveListView.setVisibility(View.VISIBLE);
            recipientListView.setVisibility(View.GONE);
            final List<MessageBean> readMessageList = messageManager
                .getMessageList("read", user.getSponsorId(), user.getUserId());
    final CheckBoxAdapter checkBoxAdapter = new CheckBoxAdapter(
                MessageActivity.this, readMessageList);
archiveListView.setAdapter(checkBoxAdapter );
        } else if (itemPosition == 3) {
            recipientListView.setVisibility(View.VISIBLE);
            listView.setVisibility(View.GONE);
            archiveListView.setVisibility(View.GONE);
            adapter = new AddressAdapter(MessageActivity.this,
                    R.layout.row_address, matchedRecipients);
            recipientListView.setAdapter(adapter);
            } else if (itemPosition == 0) {
            listView.setVisibility(View.VISIBLE);
            archiveListView.setVisibility(View.GONE);
            recipientListView.setVisibility(View.GONE);
    messageList = messageManager.getUnreadMessageList("unread",
                user.getSponsorId(), user.getUserId());
            inboxAdapter = new MessageListAdapter(MessageActivity.this,
                R.layout.custome_row_message, messageList);
         refreshYourAdapter(messageList);
                listView.setAdapter(inboxAdapter);
        } else if (itemPosition == 1) {
            listView.setVisibility(View.VISIBLE);
            archiveListView.setVisibility(View.GONE);
            recipientListView.setVisibility(View.GONE);
            inboxAdapter = new MessageListAdapter(MessageActivity.this,
                    R.layout.custome_row_message, pendingMessageList);
            refreshYourAdapter(pendingMessageList);
            listView.setAdapter(inboxAdapter);
        }
    }


private void refreshYourAdapter(final List<MessageBean> items) {
    runOnUiThread(new Runnable() {
        public void run() {
            if (inboxAdapter != null) {
                inboxAdapter.refreshAdapter(items);
            }
        }
    });
}
