随着Android的26(O)引入通知渠道我一直在调查谷歌提供的com.example.android.notificationchannels
Android的26(O)通知不显示操作图标
此示例按预期工作,直到我试图添加一个Action
到示例应用中定义的辅助通知。
我的代码类似于此: -
/**
* Build notification for secondary channel.
*
* @param title Title for notification.
* @param body Message for notification.
* @return A Notification.Builder configured with the selected channel and details
*/
@RequiresApi(api = Build.VERSION_CODES.O)
public Notification.Builder getNotification2(String title, String body) {
return new Notification.Builder(getApplicationContext(), SECONDARY_CHANNEL)
.setContentTitle(title)
.setContentText(body)
.setActions(buildAction())
.setSmallIcon(getSmallIcon())
.setAutoCancel(true);
}
和BuildAction的(): -
@TargetApi(Build.VERSION_CODES.KITKAT_WATCH)
private Notification.Action buildAction() {
final Intent intent = new Intent(this, SecondActivity.class);
final PendingIntent pendingIntent = PendingIntent.getActivity(this, 1729, intent, PendingIntent.FLAG_UPDATE_CURRENT);
final Notification.Action myAction = new Notification.Action.Builder(R.drawable.ic_action_name, "RETRY", pendingIntent).build();
return myAction;
}
显示操作,并根据需要工作,但是没有下显示的行动标题图标。
我做错了什么?
我的build.gradle文件如下所示: -
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0-alpha4'
}
}
apply plugin: 'com.android.application'
repositories {
jcenter()
}
dependencies {
compile "com.android.support:support-v4:26.+"
compile "com.android.support:support-v13:26.+"
compile "com.android.support:cardview-v7:26.+"
compile "com.android.support:appcompat-v7:26.+"
}
// The sample build uses multiple directories to
// keep boilerplate and common code separate from
// the main sample code.
List<String> dirs = [
'main', // main sample code; look here for the interesting stuff.
'common', // components that are reused by multiple samples
'template'] // boilerplate code that is generated by the sample template process
android {
compileSdkVersion 26
buildToolsVersion "26.0.0"
// Values declared here override the ones declared in AndroidManifest.xml
defaultConfig {
minSdkVersion 16
targetSdkVersion 26
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
sourceSets {
main {
dirs.each { dir ->
java.srcDirs "src/${dir}/java"
res.srcDirs "src/${dir}/res"
}
}
androidTest.setRoot('tests')
androidTest.java.srcDirs = ['tests/src']
}
}
Android的工作室细节是: -
Android Studio 3.0 Canary 4

我以为通知操作图标不显示,因为牛轧糖,只有文本。除了只显示图标的媒体样式通知。 –
因为在所有平台上都使用相同的构造函数。相同的Notification对象用于在Nougat之前的平台上呈现实际通知,并在这些平台上执行* do *图标。 –
许多问题都可以通过适当的研究完全避免。 https://android-developers.googleblog.com/2016/06/notifications-in-android-n.html在未来,如果您觉得自己有一些有趣的问题,并在正确的研究后找到答案,堆栈溢出(你可以回答自己的问题)。 –
