问题描述

我正在将 AdMob 整合到我的应用中.我已按照开发人员页面中的步骤进行操作.但是 AdRequest.Builder() 用红色下划线表示:

I'm incorporating AdMob into my app. I've followed the steps in the developers page. However AdRequest.Builder() is being underlined with red and it says:

AdRequest 无法解析为类型

AdRequest cannot be resolved to a type

和

AdRequest.Builder 无法解析为类型.

AdRequest.Builder cannot be resolved to a type.

可能是什么问题?

import com.google.ads.AdRequest;
import com.google.ads.AdView;


public class FireRoomActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fire_room);

        // Look up the AdView as a resource and load a request.
        AdView adView = (AdView)this.findViewById(R.id.adView);
        AdRequest adRequest = new AdRequest.Builder().build();   
        adView.loadAd(adRequest);
    }

在 xml 中，我已经展示了 admob:

In xml I've shown admob as such:

<com.google.android.gms.ads.AdView android:id="@+id/adView"
                     android:layout_width="wrap_content"
                     android:layout_height="wrap_content"
                     ads:adUnitId="bla bla"
                     ads:adSize="BANNER"/>

推荐答案

您的代码混合用于 Admob SDK (Google Play) 和 Android(6.4.1 及更早版本)SDK)

Your code is mix for Admob SDK (Google Play) and Android (6.4.1 and earlier SDKs)

使用

import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;

AdRequest adRequest = new AdRequest.Builder().build();

和

<com.google.android.gms.ads.AdView android:id="@+id/adView"
                     android:layout_width="wrap_content"
                     android:layout_height="wrap_content"
                     ads:adUnitId="bla bla"
                     ads:adSize="BANNER"/>

如果您使用 Admob SDK (Google Play)

if you use Admob SDK (Google Play)

或者使用

import com.google.ads.AdRequest;
import com.google.ads.AdView;

AdRequest adRequest = new AdRequest();

和

<com.google.ads.AdView android:id="@+id/adView"
                     android:layout_width="wrap_content"
                     android:layout_height="wrap_content"
                     ads:adUnitId="bla bla"
                     ads:adSize="BANNER"/>

如果你使用早期的 SDK

对于 Admob SDK (Google Play) 不要忘记更改命名空间
