Comment afficher un dialogue d'alerte sur Android?

Question

Comment afficher un dialogue d'alerte sur Android?

je veux afficher une fenêtre de dialogue / popup avec un message à l'utilisateur qui montre "Êtes-vous sûr que vous voulez supprimer cette entrée?"avec un bouton 'Supprimer'. Lorsque Delete est touché, il devrait supprimer cette entrée, sinon rien.

j'ai écrit un écouteur de clic pour ces boutons, mais comment puis-je invoquer un dialogue ou popup et sa fonctionnalité?

vous pouvez utiliser le constructeur d'alerte pour ceci:

    AlertDialog.Builder builder;
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        builder = new AlertDialog.Builder(context, android.R.style.Theme_Material_Dialog_Alert);
    } else {
        builder = new AlertDialog.Builder(context);
    }
    builder.setTitle("Delete entry")
    .setMessage("Are you sure you want to delete this entry?")
    .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) { 
            // continue with delete
        }
     })
    .setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) { 
            // do nothing
        }
     })
    .setIcon(android.R.drawable.ic_dialog_alert)

le code que David Hedlund a posté m'a donné l'erreur:

impossible d'ajouter window - token null n'est pas valide

si vous obtenez la même erreur, utilisez le code ci-dessous. Il fonctionne!!

runOnUiThread(new Runnable() {
    @Override
    public void run() {

        if (!isFinishing()){
            new AlertDialog.Builder(YourActivity.this)

un simple! Créez une méthode de dialogue, quelque chose comme ceci n'importe où dans votre classe Java:

public void openDialog() {
    final Dialog dialog = new Dialog(context); // Context, this, etc.
    dialog.setContentView(R.layout.dialog_demo);
    dialog.setTitle(R.string.dialog_title);
    dialog.show();
}

créez maintenant le format XML dialog_demo.xml et créez votre interface utilisateur/design. Voici un exemple que j'ai créé à des fins de démonstration:

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

    <TextView
        android:id="@+id/dialog_info"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:text="@string/dialog_text"/>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:layout_below="@id/dialog_info">

        <Button
            android:id="@+id/dialog_cancel"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="0.50"
            android:background="@color/dialog_cancel_bgcolor"
            android:text="Cancel"/>

        <Button
            android:id="@+id/dialog_ok"
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="0.50"
            android:background="@color/dialog_ok_bgcolor"
            android:text="Agree"/>
    </LinearLayout>
</RelativeLayout>

Maintenant vous pouvez appeler openDialog() de n'importe où vous voulez :) Voici la capture d'écran du code ci-dessus.

il suffit d'être prudent lorsque vous voulez rejeter le dialogue - utiliser dialog.dismiss() . Dans ma première tentative, j'ai utilisé dismissDialog(0) (que j'ai probablement copié d'un endroit) qui parfois œuvres. L'utilisation de l'objet fourni par le système semble être un choix plus sûr.

vous pouvez créer la boîte de dialogue en utilisant AlertDialog.Builder

essayez ceci:

AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setMessage("Are you sure you want to delete this entry?");

        builder.setPositiveButton("Yes, please", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                //perform any action
                Toast.makeText(getApplicationContext(), "Yes clicked", Toast.LENGTH_SHORT).show();
            }
        });

        builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                //perform any action
                Toast.makeText(getApplicationContext(), "No clicked", Toast.LENGTH_SHORT).show();
            }
        });

        //creating alert dialog
        AlertDialog alertDialog = builder.create();
        alertDialog.show();

pour changer la couleur des boutons positifs et négatifs de la boîte de dialogue Alerte, vous pouvez écrire les deux lignes suivantes après alertDialog.show();

alertDialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(getResources().getColor(R.color.colorPrimary));
alertDialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(getResources().getColor(R.color.colorPrimaryDark));

vous pouvez créer L'activité et étend L'Appcompatactivité. Puis dans le Manifeste mettre le style suivant:

<activity android:name=".YourCustomDialog"
            android:theme="Theme.AppCompat.Light.Dialog">
</activity>

le gonfler par des boutons et des TextViews

alors utilisez ceci comme un dialogue.

par exemple, dans la linéarité, je remplis les paramètres suivants:

android:layout_width="300dp"
android:layout_height="wrap_content"

In Kotlin

fun showDialog(@NonNull context: Context, @NonNull title: String, @NonNull msg: String,
               @NonNull positiveBtnText: String, @Nullable negativeBtnText: String?,
               @NonNull positiveBtnClickListener: DialogInterface.OnClickListener,
               @Nullable negativeBtnClickListener: DialogInterface.OnClickListener): AlertDialog {
    val builder = AlertDialog.Builder(context)
            .setTitle(title)
            .setMessage(msg)
            .setCancelable(true)
            .setPositiveButton(positiveBtnText, positiveBtnClickListener)
    if (negativeBtnText != null)
        builder.setNegativeButton(negativeBtnText, negativeBtnClickListener)
    val alert = builder.create()
    alert.show()
    return alert
}
