Comment terminer une activité avec une boîte de dialogue

Question

Je suis en train de programmer un jeu simple, et maintenant, je veux que mon application affiche une boîte de dialogue, quand un compte à rebours se termine. Je tryed ce code (voir ci-dessous), mais il ne fonctionne pas:

protected void alertbox() 
    { 
    new AlertDialog.Builder(this) 
     .setMessage("You've scored " + score + " points!") 
     .setTitle("Congatulations!") 
     .setCancelable(false) 
     .setNeutralButton(android.R.string.cancel, 
     new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int whichButton){} 
     ButtonActivity.this.finish(); 
     }) 
     .show(); 
    } 

Answer 1

Essayez ceci:

new AlertDialog.Builder(context).setMessage("Congratulations! You scored " + score + " points!") 
.setPositiveButton("Ok", new DialogInterface.OnClickListener() 
{ 
    @Override 
    public void onClick(DialogInterface dialog, int which) 
    { 
     finish(); 
    } 
}).show(); 

Answer 2

faire comme ça:

final Dialog dialog = new Dialog(ButtonActivity.this); 
    dialog.setContentView(R.layout.dialog); 
    dialog.setTitle("Dialog Title"); 
    TextView text = (TextView) dialog.findViewById(R.id.text); 
    text.setText("Congratulations! You scored " + score + " points!"); 
    Button dialogButton = (Button) dialog.findViewById(R.id.dialogButtonOK); 

    dialogButton.setOnClickListener(new OnClickListener() { 
     @Override 
     public void onClick(View v) { 
     dialog.dismiss(); 
     ButtonActivity.this.finish(); 
     } 
    }); 
    dialog.show(); 

dialog.xml:

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 



    <TextView 
     android:id="@+id/text" 
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:textColor="#FFF" 
     /> 

    <Button 
     android:id="@+id/dialogButtonOK" 
     android:layout_width="100px" 
     android:layout_height="wrap_content" 
     android:text="Ok" 
     android:layout_marginTop="5dp" 
     android:layout_marginRight="5dp" 
     android:layout_below="@+id/text" 
     /> 

</RelativeLayout>

protected void alertbox(){ 
    new AlertDialog.Builder(this) 
    .setMessage("You've scored " + score + " points!") 
    .setTitle("Congatulations!") 
    .setCancelable(false) 
    .setNeutralButton(android.R.string.cancel, 
    new DialogInterface.OnClickListener() { 
    public void onClick(DialogInterface dialog, int whichButton){ 
     Intent intent =new Intent(getApplicationContext(), NextActivityClassName.class); 
     intent.putExtra("ID",score); 
     startActivity(intent); 
     finish(); 
    } 
    }).show(); 

}

Dans la prochaine utilisation de l'activité:

int scoreValue= getIntent().getIntExtra("ID", defaultValueIntValue);
