1- Android Clipboard

Sous Android, Clipboard est une structure (framework) très utile pour copier (copy) et coller (paste) différents types de données, par exemple: texte, image, données de flux binaires et autres types de données complexes.
Précisément, si les données sont de type texte brut, lorsqu'elles sont copiées, elles sont stockées dans Clipboard.
Une fois copiées, les données complexes sont stockées comme une référence (reference). Et l'application coller (pasting application) doit utiliser ContentProvider pour analyser le contenu.
Afin d'utiliser Android Clipboard Framework, votre application doit placer les données dans l'objet ClipData, puis placer cet objet dans le système Clipboard. Toutes les applications suivant les règles ci-dessus peuvent copier et coller les données entre elles.
Un objet ClipData est créé par l'une des méthodes statiques suivantes:
* Copy & Paste *
private void doCopy()  {
    this.clipboardManager = (ClipboardManager) this.getSystemService(Context.CLIPBOARD_SERVICE);

    String txtCopy = "Hello World";
    
    // ClipData (Plain Text)
    ClipData clipData = ClipData.newPlainText("Some label", txtCopy);
    
    // Copy ClipData to Clipboard.
    this.clipboardManager.setPrimaryClip(clipData);
}

private void doPaste()  {
    ClipData primaryClipData = this.clipboardManager.getPrimaryClip();

    ClipData.Item item = primaryClipData.getItemAt(0);

    // Text in the Clipboard.
    String txtPaste = item.getText().toString();
}

2- Exemple: Clipboard (Text brut)

Copier et coller les textes bruts (Plain Text) est la démarche la plus courante et simple dans les applications d' Android. En voici un exemple:
L'interface de l'application

        this.editTextPaste.setText(txtPaste);

        Toast.makeText(getApplicationContext(),"Data Pasted from Clipboard",Toast.LENGTH_SHORT).show();
    }

}

3- Exemple de Clipboard (Intention)

Les Intent(s) peuvent également être copiées dans Clipbooard. Dans cet exemple, je crée une simple Intent pour ouvrir une URL dans le navigateur. On peut copier cette Intent dans Clipboard.

4- Exemple de Clipboard (URI)

Pour copier une image, il faut la convertir en un Uri et copier cet Uri dans Clipboard. Dans cet exemple, je copie une image dans le dossier "drawable" dans Clipboard.
Copier quelques fichiers image dans le dossier "drawable":
icon_cry.png icon_feel_good.png
Dans Android Studio, on crée une nouvelle Activity nommée ImageActivity pour afficher l'image copiée dans Clipboard.
  • File > New > Activity > Empty Activity
Android Studio crée deux fichiers: ImageActivity.java et activity_image.xml, en même temps ImageActivity est enregistré dans AndroidManifest.xml:
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="org.o7planning.clipboarduriexample">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <!-- ImageActivity -->
        <activity android:name=".ImageActivity"></activity>
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
