我正在尝试加载Admob原生广告.之前(在应用更新之前)广告过去曾经展示但现在却没有展示.我已经发布了代码,xml和下面的Logcat.

码

NativeExpressAdView adView = (NativeExpressAdView) myView.findViewById(R.id.adView);

    AdRequest request = new AdRequest.Builder()
            .addTestDevice("5BCFF0AAE83AF424648A954038C71DE6")
            .addTestDevice("A5E3E2068BD88202CBC281AD76984BEE")//infocus
            .build();

    adView.loadAd(request);

XML

<com.google.android.gms.ads.NativeExpressAdView
            android:id="@+id/adView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            ads:adSize="320x150"
            ads:adUnitId="ca-app-pub-5059726881726792/6223900262"></com.google.android.gms.ads.NativeExpressAdView>

logcat的

我试图用简单的String数据填充RecyclerView但是recyclerView.setAdapter(adapter);给出了错误.有什么问题？

我是recyclerview的新手.

RecyclerView recyclerView;
String []data = {"ankush", "kapoor"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    recyclerView = (RecyclerView) findViewById(R.id.myRecyclerView);
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, data);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
    recyclerView.setAdapter(adapter);
}

我怎样才能获得当前选定的导航抽屉项目？我的菜单存储在drawer_menu.xml中

navigationView = (NavigationView) findViewById(R.id.navigation_view);
    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(MenuItem item) {
            switch (item.getItemId()) {
                case R.id.change_sec:
                    Intent intent_sec = new Intent(MainActivity.this, ClassDataProvider.class);
                    startActivityForResult(intent_sec, 9);
                    drawerLayout.closeDrawers();
                    break;
                case R.id.holiday_list:
                    Intent intent = new Intent(MainActivity.this, HolidayList.class);
                    startActivity(intent);
                    drawerLayout.closeDrawers();
                    break;
            }
            return true;
        }
    });

我在stackoverflow上尝试了很多解决方案,但没有一个对我有用.当我同步它给出的项目时Error:(2, 0) Plugin with id 'com.google.gms.google-services' not found

正如文档所述(最后添加插件)我做了同样的事情.最后添加了插件. apply plugin: 'com.google.gms.google-services'

任何方案？我按照这个链接.与它说的相同,但有错误.

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"

    defaultConfig {
        applicationId "com.radioaudio.motivationalaudios"

        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile files('libs/YouTubeAndroidPlayerApi.jar')
    compile 'com.google.firebase:firebase-ads:9.4.0'
}
apply plugin: 'com.google.gms.google-services'

发送信号推送通知后,Android应用程序崩溃.我收到了这个错误.尝试查看其他stackoverflow答案,但它没有帮助.

请检查下面的代码(build.gradle)和错误.

不明白为什么它不工作:P请检查下面的代码(build.gradle)和错误.

我收到以下错误:

Failed to resolve: com.android.support:design-v7:23.0.0 

我已经更新了所有需要的skd工具(比如android支持库,存储库)但是当我同步项目时它会显示Error.即使单击"安装存储库和同步项目"也没有任何反应.

我已经检查了其他问题,但它们对我不起作用.
