我的活动我正在使用后台服务,我每7秒钟从json获取数据。并在UI线程上更新我的列表视图。有时会有大量日期,列表视图会滚动它的崩溃。使用此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。
android.os.Handler handler_service = new android.os.Handler() {
public void handleMessage(android.os.Message msg) {
runOnUiThread(new Runnable() {
@Override
public synchronized void run() {
if (jon_list_Adapter == null) {
try {
jon_list_Adapter = new Different_Job_List_Adapter(
getApplicationContext(),
Different_Job_List.getInstance(),
Driver_Request_JobActivity.this);
listdriver_invites.setAdapter(jon_list_Adapter);
jon_list_Adapter.notifyDataSetChanged();
// notifyDataSetChanged();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
} else {
try {
jon_list_Adapter.notifyDataSetChanged();
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
}
}
});
};
};

You need to call notifyDataSetChanged() in the adapter, so set up a method called refreshData in the adapter like this:
public void refreshData(ArrayList<yourList> data) {
mValues.clear();
mValues.addAll(data);
notifyDataSetChanged();
}
and call from your activity:
json_list_Adapter.refreshData(newData)
with the new data as an argument.
