एंड्रॉइड NotificationBuilder उदाहरण

NotificationCompat.Builder का बेसिक उदाहरण

यह आर्टिकल NotificationCompat.Builder से सिंपल नोटिफिकेशन बनाने का न्यूनतम कोड दिखाता है।

चरण 1: नया प्रोजेक्ट

Android Studio में File → New Project।

चरण 2: लेआउट

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

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:layout_margin="16dp"
        android:onClick="createNotification"
        android:text="Create Notification" />
</RelativeLayout>

चरण 3: MainActivity

package app.tutorialspoint.com.notifyme;

import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.os.Bundle;
import android.support.v4.app.NotificationCompat;
import android.support.v7.app.AppCompatActivity;
import android.view.View;

public class MainActivity extends AppCompatActivity {
    public static final String NOTIFICATION_CHANNEL_ID = "10001";
    private final static String default_notification_channel_id = "default";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void createNotification(View view) {
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(MainActivity.this, default_notification_channel_id);

        mBuilder.setContentTitle("Notify Me 😀");
        mBuilder.setContentText("Something important!");
        mBuilder.setSmallIcon(R.drawable.ic_launcher_foreground);
        mBuilder.setAutoCancel(true);

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            int importance = NotificationManager.IMPORTANCE_HIGH;
            NotificationChannel notificationChannel = new NotificationChannel(NOTIFICATION_CHANNEL_ID, "NOTIFICATION_CHANNEL_NAME", importance);
            mBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);
            assert mNotificationManager != null;
            mNotificationManager.createNotificationChannel(notificationChannel);
        }

        assert mNotificationManager != null;
        mNotificationManager.notify((int) System.currentTimeMillis(), mBuilder.build());
    }
}

चरण 4: मैनिफेस्ट

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="https://schemas.android.com/apk/res/android"
    package="app.tutorialspoint.com.notifyme">

    <uses-permission android:name="android.permission.VIBRATE" />

    <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">

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