AdMob in a fragment | 易学教程

问题

I'm inserting an AdMob in my application. but I have a problem about it.

when I inserted some codes about it in Eclipse, I can see an error message about "the constructor AdRequest() is not visible " in a fragment_03 and "error: Error parsing XML : unbound prefix" from "

so I attached source for the AdMob as follows.

Can you give me an advice ?

Let me know if you have any question.

Thanks

fragment_03.java

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

public class Fragment_03 extends Fragment {

private AdView adView;
private AdRequest adRequest;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_03, container, false);

    adRequest = new AdRequest();
    adView = (AdView) rootView.findViewById(R.id.fragment_03_admob);
    adView.loadAd(adRequest);

    return rootView;
    }
}

fragment_03.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <com.google.android.ads.AdView
        xmlns:ads="schemas.android.com/apk/lib/com.google.ads"
        android:id="@+id/fragment_03_admob"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:adSize="BANNER"
        app:adUnitId="@string/activity_admobID"
        app:loadAdOnCreate="true"
        app:testDevices="TEST_EMULATOR, TEST_DEVICE_ID" />

</LinearLayout>

AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />

<activity
        android:name="com.google.ads.AdActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" />

回答1:

Change your layout in this way:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="schemas.android.com/apk/lib/com.google.ads"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <com.google.android.ads.AdView
        android:id="@+id/fragment_03_admob"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:adSize="BANNER"
        app:adUnitId="@string/activity_admobID"
        app:loadAdOnCreate="true"
        app:testDevices="TEST_EMULATOR, TEST_DEVICE_ID" />

</LinearLayout>

You was using a wrong namespace declaration.

You have to write root before the findViewById:

AdView mAdView = (AdView) root.findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
