NotificationCompat.Builder不接受第二个参数
NotificationCompat.Builder不接受第二个参数
提问于 2018-06-09 01:44:45
由于某些原因，我的NotificationCompat.Builder不接受第二个参数，我不知道如何修复它。我看到了一些其他的答案，但大多数问题都在gradle版本中，但我的答案是最新的，如下所示：
if (Build.VERSION.SDK_INT >= 26) {
Intent notificationIntent = new Intent(this, MainActivity.class);
PendingIntent mPendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
Notification mNotification = new NotificationCompat.Builder(this, CHANNEL_ID)
.setContentTitle("Content Title")
.setContentText("Content Text")
.setSmallIcon(R.drawable.ic_check)
.setContentIntent(mPendingIntent)
.build();
startForeground(1, mNotification);
mNotification.notify();
}这些是我的gradle文件
build.gradle:project
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.2'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}build.gradle:app
apply plugin: 'com.android.application'
android {
compileSdkVersion 26
defaultConfig {
applicationId "rs.dreamlight.parkomat"
minSdkVersion 15
targetSdkVersion 26
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:support-v4:26.1.0'
implementation 'com.android.support.constraint:constraint-layout:1.0.2'
implementation 'com.android.support:support-vector-drawable:26.1.0'
implementation 'com.google.code.gson:gson:2.8.4'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
implementation 'com.android.support:design:26.1.0'
implementation 'com.android.support:cardview-v7:26.1.0'
implementation 'com.github.clans:fab:1.6.4'
}有什么想法吗？

请确保包含正确版本的NotificationCompat库：import android.support.v4.app.NotificationCompat;。这是关于通知频道的官方指南，这是安卓O：https://developer.android.com/training/notify-user/channels的一个新功能。
