my dialogue in android activity crashes, what i missing?

Question

This is my OnClickListener where i overloading my method called

DialogueSuccessful();

which should Launch Dialouge.

if (Inserted == true) {
    DialogueSuccessful();
    txt_FromDate.setText("");
    txt_ToDate.setText("");
    txt_total_payment.setText("");
} else {
    Toast.makeText(getApplicationContext(), "Did not Insert Data", Toast.LENGTH_LONG).show();
}

Here is my method implementation, app crashes during method implementation

public void DialogueSuccessful() {
    AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());
    builder.setMessage("Successfull")
        .setTitle("Hotels Reservation")
        .setPositiveButton("Nice", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int id) {
                // FIRE ZE MISSILES!
            }
        });
    // Create the AlertDialog object and return it
    AlertDialog Dialogue = builder.create();
    Dialogue.show();
}

This is my Exception at logcat:

Change method signature to `public void DialogueSuccessful(View view)` if using `android:onclick="DialogueSuccessful"` in xml — ρяσѕρєя K, Nov 02 '16 at 08:13
Also instead of using `getApplicationContext()` use current Activity Context to create AlertDialog — ρяσѕρєя K, Nov 02 '16 at 08:14

add

android:theme="@style/Theme.AppCompat.Light"

in your AndroidManifest.xml file activity tag.

i think you have use onClick attribute in your xml-layout file. Also you have not use suitable theme for your project. show your xml or app theme activity.

modify you dialogueSuccessful method

replace this line

AlertDialog.Builder builder = new AlertDialog.Builder(getApplicationContext());

with

AlertDialog.Builder builder =new AlertDialog.Builder(
  new ContextThemeWrapper(getApplicationContext(), android.R.style.Theme_Dialog));

switching from

getApplicationContext()

to Activity Context is succesul

public void DialogueSuccessful(){
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setMessage("Successfull")
            .setTitle("Hotels Reservation")
            .setPositiveButton("Nice", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    // FIRE ZE MISSILES!
                }
            });
    // Create the AlertDialog object and return it
    AlertDialog Dialogue=builder.create();
    Dialogue.show();
}

my dialogue in android activity crashes, what i missing?
