【问题描述】:
我想在okhttp中添加progressdialog(异步,不是AsyncTask)
但我收到了这个错误:
错误:无法在未调用的线程内创建处理程序 Looper.prepare()
如何以适当的方式修复它?我想确定这是最好的方法。
client.newCall(request).enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
Log.d("TAG_response", " brak neta lub polaczenia z serwerem ");
e.printStackTrace();
}
@Override
public void onResponse(Call call, Response response) throws IOException {
progress = ProgressDialog.show(SignUp.this, "dialog title",
"dialog message", true);
try {
Log.d("TAGx", response.body().string());
if (response.isSuccessful()) {
Headers responseHeaders = response.headers();
for (int i = 0, size = responseHeaders.size(); i < size; i++) {
//System.out.println(responseHeaders.name(i) + ": " + responseHeaders.value(i));
Log.d("TAG2", responseHeaders.name(i));
Log.d("TAG3", responseHeaders.value(i));
}
Log.d("TAG", response.body().string());
progress.dismiss();
main_activity();
}
else{
progress.dismiss();
alertUserAboutError();
}
}
catch (IOException e){
Log.d("TAG", "error");
}
}
});
【问题讨论】:
-
您应该在将请求排入队列并在 onFailure 和 onResponse 中关闭之前移动显示对话框的代码。
