notifysetdatachanged（）错误如何设置？

Answer 1

请使用以下代码修复错误...

adapter.notifyDataSetChanged（）;

Answer 2

流程：com.example.guru.pro，PID：14411 java.lang.IllegalStateException：适配器的内容已更改，但ListView未收到通知。确保不从后台线程修改适配器的内容，而只是从UI线程修改。确保适配器在其内容更改时调用notifyDataSetChanged（）。 [在ListView（2131558572，类android.widget.ListView）中使用Adapter（类android.widget.SimpleAdapter）] 在android.widget.ListView.layoutChildren（ListView.java:1573）在android.widget.AbsListView.onLayout（AbsListView.java:2222）在android.view.View.layout（View.java:15900）

Answer 3

@Override
protected void onPostExecute(Void result) {
    super.onPostExecute(result);
    final SimpleAdapter adapter = new SimpleAdapter(Appointments.this, contactListpnt,R.layout.appointmentlist, abc,new int[]{R.id.tpatientapt, R.id.tphnapt, R.id.tdateapt, R.id.ttymapt, R.id.ttypep, R.id.tstatusp, R.id.tflwupsp, R.id.tnotesp});

    adapter.notifyDataSetChanged();
    listaptmnt.setAdapter(adapter);
}

    java.lang.IllegalStateException: The content of the adapter has changed but ListView did not receive a notification. Make sure the content of your adapter is not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifyDataSetChanged() when its content changes. [in ListView(2131558572, class android.widget.ListView) with Adapter(class android.widget.SimpleAdapter)]

Answer 4

将你的notifySetDataChanged放在uithread：

中

runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    adapter. notifysetdatachanged();
                }
            });
