Display a NumberPicker on an AlertDialog
android, android-alertdialog, numberpicker
Solution
You never set the view of the Dialog.
builder.setView(numberPicker);
Problem
I am trying to display a NumberPicker on an AlertDialog. The AlertDialog works, but it doesn't show the NumberPicker. Here is my code ``` public Dialog onCreateDialog(Bundle savedInstanceState){ final NumberPicker numberPicker = new NumberPicker(getActivity()); numberPicker.setMaxValue(360); numberPicker.setMinValue(0); AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); builder.setTitle("Changing the Hue"); builder.setMessage("Choose a value :"); builder.setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { dialogHost.onPositiveButton(numberPicker.getValue()); } }); builder.setNegativeButton("CANCEL", new DialogInterface.OnClickListener(){ @Override public void onClick(DialogInterface dialog, int which) { dialogHost.onCancelButton(); } }); return builder.create(); } ```
