我正在尝试在android studio中构建一个警报框，我有2个xml和1个活动类，在单击按钮时我要显示其他布局。我遇到错误，这是我的MainActivity代码
cancelBookingButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
LayoutInflater inflater = getLayoutInflater();
View alertLayout = inflater.inflate(R.layout.alert_cancel_confirm, null);
final TextView disAgree = (TextView) alertLayout.findViewById(R.id.TextDisagree);
final TextView Agree = (TextView) alertLayout.findViewById(R.id.TextAgree);
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Current Booking");
// This will set the view from XML inside ALertDialog
alert.setView(alertLayout);
// disabling cancel of AlertDialog on click of back button and outside touch
alert.setCancelable(false);
AlertDialog dialog = alert.create();
dialog.show();
}
});
在这一行，我越来越错误
AlertDialog.Builder alert = new AlertDialog.Builder(this);
在Builder中无法应用任何想法我为什么要这样做。
AlertDialog.Builder alert = new AlertDialog.Builder(YourActivity.this);
alert.setTitle("Current Booking");
// This will set the view from XML inside ALertDialog
alert.setView(alertLayout);
// disabling cancel of AlertDialog on click of back button and outside touch
alert.setCancelable(false);
AlertDialog dialog = alert.create();
dialog.show();
