getSupportFragmentManager().getFragments() 显示编译时错误

调用显示编译时错误,并显示以下消息:getSupportFragmentManager().getFragments()
getSupportFragmentManager().getFragments() 只能从同一库组(groupId = com.android.support) 中调用
我已经导入了以下类:MainActivity
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.design.widget.BottomNavigationView;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.MenuItem;
import android.widget.Toast;
MainActivity
延伸。AppCompatActivity
我的项目模块级文件如下:build.gradle
apply plugin: 'com.android.application'
android {
compileSdkVersion 25
buildToolsVersion "25.0.2"
defaultConfig {
applicationId "com.mycompany.floatingdemo"
minSdkVersion 16
targetSdkVersion 25
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 {
compile fileTree(dir: 'libs', include: ['*.jar'])
androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:25.2.0'
compile 'com.android.support:design:25.2.0'
compile 'com.android.support:support-vector-drawable:25.2.0'
testCompile 'junit:junit:4.12'
}
这是 内部方法的源代码。getFragments
FragmentManager.java
/**
* Get a list of all fragments that have been added to the fragment manager.
*
* @return The list of all fragments or null if none.
* @hide
*/
@RestrictTo(LIBRARY_GROUP)
public abstract List<Fragment> getFragments();
我最近将我的Android Studio更新到最新的稳定版本(2.3),并更新了Android Gradle插件。我认为这可能是相关的,因为我以前没有看到过这个错误。
