在AlertDialog中选择positiveButton时，将editText输入添加到recyclerView(Adding editText input to recyclerView when positiveButton is selected in AlertDialog)
我试图从editText字段获取输入以更新到我的recyclerView。 为了实现这一目标，我需要添加或删除我的代码？ 我正在使用一个已经包含一些数据的arraylist。 现在我想要和列表中的新标题。 当用户点击FAB时，我设置了一个警告对话框，显示他们可以输入名称的位置。 一旦用户按下是，我希望该名称转到recyclerView。
public class Workout extends Fragment {
RecyclerView recyclerView;
RecyclerView.Adapter adapter;
RecyclerView.LayoutManager layoutManager;
ArrayList < RoutineList > list = new ArrayList < RoutineList > ();
String[] name;

fab.setOnClickListener(new View.OnClickListener() {@

// Get the layout inflater
LayoutInflater inflater = getActivity().getLayoutInflater();
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
view = inflater.inflate(R.layout.dialog_fab, null);
final EditText routineName = (EditText) view.findViewById(R.id.workoutTitle);
builder.setView(view)
// Add action buttons
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
if (!TextUtils.isEmpty(routineName.getText().toString())) {
// This block is responsible for checking if editText is empty and carrying out the action
}
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User cancelled the dialog

这就是arraylist正在拉取已经制作的数据的地方。
public class VersionModel {
public static final String[] data = {
"Full Body", "Power Legs", "Traps Day", "Arm Blast", "Butt Toner",
"Fat Killer", "Lower Body", "Big Arms", "Tri Day",
"Bigger Chest", "Cardio", "Back Blast", "Forearms", "Calf Day", "Train for 5K"
};
}
I am trying to get input from the editText field to update to my recyclerView. What do I need to add or take away from my code to make this happen? I am using a arraylist with some data already in it. Now I want and new titles to the list. I have it setup when user taps the FAB an alert dialog shows where they can enter a name. Once user press yes I would like that name to go to the recyclerView.
public class Workout extends Fragment {
RecyclerView recyclerView;
RecyclerView.Adapter adapter;
RecyclerView.LayoutManager layoutManager;
ArrayList < RoutineList > list = new ArrayList < RoutineList > ();
String[] name;

This is where arraylist is pulling already made data.
public class VersionModel {
public static final String[] data = {
"Full Body", "Power Legs", "Traps Day", "Arm Blast", "Butt Toner",
"Fat Killer", "Lower Body", "Big Arms", "Tri Day",
"Bigger Chest", "Cardio", "Back Blast", "Forearms", "Calf Day", "Train for 5K"
};
}
最满意答案
//将新例程名称添加到列表list.add（routineName）;
// Then notify the your adapter that list has changed
adapter.notifyDataSetChange();
// Add the new routine name to your list list.add(routineName);
// Then notify the your adapter that list has changed
adapter.notifyDataSetChange();
