此示例演示了 Android Oreo 及更高版本自定义通知声音
步骤 1 − 在 Android Studio 中创建一个新项目，前往"文件"->"新建项目"，并填写所有必需信息以创建新项目。
步骤 2 − 将以下代码添加到 res/layout/activity_main.xml。
<? xml version = "1.0" encoding = "utf-8" ?> <android.support.constraint.ConstraintLayout xmlns: android = "http://schemas.android.com/apk/res/android" xmlns: app = "http://schemas.android.com/apk/res-auto" xmlns: tools = "http://schemas.android.com/tools" android :layout_width = "match_parent" android :layout_height = "match_parent" android :padding = "16dp" tools :context = ".MainActivity" > <Button android :id = "@+id/btnCreateNotification" android :layout_width = "0dp" android :layout_height = "wrap_content" android :text = "Create notification" app :layout_constraintBottom_toBottomOf = "parent" app :layout_constraintEnd_toEndOf = "parent" app :layout_constraintStart_toStartOf = "parent" app :layout_constraintTop_toTopOf = "parent" /> </android.support.constraint.ConstraintLayout>
步骤 3 − 在 raw 文件夹中添加声音
步骤 4 − 将以下代码添加到 src/MainActivity.java
package app.tutorialspoint.com.notifyme ;
import android.app.NotificationChannel ;
import android.app.NotificationManager ;
import android.content.ContentResolver ;
import android.content.Context ;
import android.graphics.Color ;
import android.media.AudioAttributes ;
import android.net.Uri ;
import android.support.v4.app.NotificationCompat ;
import android.support.v7.app.AppCompatActivity ;
import android.os.Bundle ;
import android.view.View ;
import android.widget.Button ;
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 ) ;
Button btnCreateNotification = findViewById(R.id. btnCreateNotification ) ;
btnCreateNotification.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick (View v) {
Uri sound = Uri. parse (ContentResolver. SCHEME_ANDROID_RESOURCE + "://" + getPackageName() + "/raw/quite_impressed.mp3" ) ;
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(MainActivity. this, default_notification_channel_id )
.setSmallIcon(R.drawable. ic_launcher_foreground )
.setContentTitle( "Test" )
.setSound(sound)
.setContentText( "Hello! This is my first push
notification" ) ;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context. NOTIFICATION_SERVICE );
if (android.os.Build.VERSION. SDK_INT >= android.os.Build.VERSION_CODES. O ) {
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setContentType(AudioAttributes. CONTENT_TYPE_SONIFICATION )
.setUsage(AudioAttributes. USAGE_ALARM )
.build() ;
int importance = NotificationManager. IMPORTANCE_HIGH ;
NotificationChannel notificationChannel = new NotificationChannel( NOTIFICATION_CHANNEL_ID , "NOTIFICATION_CHANNEL_NAME" , importance) ;
notificationChannel.enableLights( true ) ;
notificationChannel.setLightColor(Color. RED ) ;
notificationChannel.enableVibration( true ) ;
notificationChannel.setVibrationPattern( new long []{ 100 , 200 , 300 , 400 , 500 , 400 , 300 , 200 , 400 }) ;
notificationChannel.setSound(sound , audioAttributes) ;
mBuilder.setChannelId( NOTIFICATION_CHANNEL_ID ) ;
assert mNotificationManager != null;
mNotificationManager.createNotificationChannel(notificationChannel) ;
}
assert mNotificationManager != null;
mNotificationManager.notify(( int ) System. currentTimeMillis () ,
mBuilder.build()) ;
}
}) ;
}
}
步骤 5 − 将以下代码添加到 androidManifest.xml
<? xml version= "1.0" encoding= "utf-8" ?> <manifest xmlns: android = "http://schemas.android.com/apk/res/android" package= "app.tutorialspoint.com.notifyme" > <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>
让我们尝试运行您的应用程序。假设您已将实际的 Android 移动设备连接到电脑。要从 Android Studio 运行该应用程序，请打开项目的某个活动文件，然后点击工具栏上的"运行"图标 
。选择您的移动设备作为选项，然后勾选将显示默认屏幕 − 的移动设备。
