How to wrap up dialogs in class?

Question

I am developing an android app and I noticed I use the same dialogs in different fragments/Activities.

I was trying to wrap it in a class but my app is crashing whenever is time to show the dialog. Any ideas?

dialog class

public class Diaglogs {
+
+    private Context context;
+
+    public Diaglogs(Context context) {
+        this.context = context;
+    }
+
+    public void createPlaylistDialog() {
+        AlertDialog.Builder builder = new AlertDialog.Builder(context);
+        builder.setTitle("Enter name of the playlist");
+
+        // Set up the input
+        final EditText input = new EditText(context);
+
+        // Specify the type of input expected; this, for example, sets the input as a password, and will mask the text
+        input.setInputType(InputType.TYPE_CLASS_TEXT);
+        builder.setView(input);
+
+        // Set up the buttons
+        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
+            @Override
+            public void onClick(DialogInterface dialog, int which) {
+                String playListName = input.getText().toString();
+                if (!"".equals(playListName)) {
+                    Toast.makeText(context, "the c=playlist would be created here", Toast.LENGTH_SHORT);
+                } else {
+
+                }
+            }
+        });
+        builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
+            @Override
+            public void onClick(DialogInterface dialog, int which) {
+                dialog.cancel();
+            }
+        });
+        builder.show();
+    }
+
+}

error

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

I think the issue is not about showing the alert dialog,check this anwser..http://stackoverflow.com/a/21815015/1537419 — Srinivasan, May 11 '16 at 04:47

DialogFragment is intended for this purpose.

For simple "ok, no" you may use builder, but with DialogFragment it's easier to handle configuration changes.

PS: for errors always show your stacktace.

This type of error occurring when you can use one dialog in different type of Activity.

So, You can add specific dialog Theme to your dialog as below example:

 new AlertDialog.Builder(
  new ContextThemeWrapper(context, android.R.style.Theme_Dialog));

I am actually trying to make one class to hold all my dialogs. Meaning if I have a yes/no dialog call myClass.yesNoDialog() or myClass.inputDialog() So in the activity class I would instantiate MyClass. is there a way to do this? – Beto May 13 '16 at 04:02
