要在Android中使用NotificationCompat中的Person,您可以按照以下步骤进行操作:
implementation 'androidx.core:core-ktx:1.5.0'
import android.app.NotificationChannel
import android.app.NotificationManager
import android.content.Context
import android.graphics.BitmapFactory
import android.os.Build
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
import androidx.core.app.NotificationCompat
import androidx.core.app.Person
import androidx.core.graphics.drawable.IconCompat
class MainActivity : AppCompatActivity() {
private val CHANNEL_ID = "channel_id"
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
createNotificationChannel()
val notificationBuilder = NotificationCompat.Builder(this, CHANNEL_ID)
.setSmallIcon(R.drawable.ic_notification)
.setContentTitle("Notification Title")
.setContentText("Notification Text")
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
val personIcon = IconCompat.createWithBitmap(
BitmapFactory.decodeResource(resources, R.drawable.person_icon)
).toIcon()
val person = Person.Builder()
.setName("Person Name")
.setIcon(personIcon)
.build()
notificationBuilder.setPerson(person)
}
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.notify(0, notificationBuilder.build())
}
private fun createNotificationChannel() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channel = NotificationChannel(
CHANNEL_ID,
"Channel Name",
NotificationManager.IMPORTANCE_DEFAULT
)
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.createNotificationChannel(channel)
}
}
}
上述代码首先为您的通知创建了一个NotificationChannel。然后,它构建了一个NotificationCompat.Builder,并设置了一些基本的通知属性,如小图标、标题和文本。接下来,它检查设备的Android版本,如果版本大于等于P(Android 9.0),则创建了一个Person对象,并将其设置为通知的Person。最后,它使用NotificationManager将通知显示在设备上。
请注意,上述示例中的R.drawable.ic_notification和R.drawable.person_icon是您应根据您项目中的实际资源进行替换的图标资源。
