过几秒后，广告回来了，但是却出现以下的错误，但是又不能传一个Handler进去，郁闷，有人知道怎么解决的么？

早上在床上想到的方法：（经测试可行）

1.先在Activity的onCreate里面，先创建AdView

 // Create the adView
// Please replace MY_BANNER_UNIT_ID with your AdMob Publisher ID
 mAdView = new AdView(this, AdSize.BANNER, MY_BANNER_UNIT_ID);
 mAdView.setAdListener(this);
// Initiate a generic request to load it with an ad
 AdRequest ad = new AdRequest();
 mAdView.loadAd(ad);

2.让Activity实现接口(implements AdListener)

3.接着在 onReceiveAd里面用Handler来刷新页面

 @Override
public void onReceiveAd(Ad arg0) {
if(handler != null){
 handler.sendEmptyMessage(ADS_INCOMMING);
 }
 }

4.当然，要在Handler处理消息了:

 private Handler handler = new Handler(){
 @Override
public void handleMessage(Message msg) {
switch(msg.what){
case ADS_COMMING:{
 root.addView(mAdView, new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, 
 LinearLayout.LayoutParams.WRAP_CONTENT));
break;
 }
 }
 }

其中的root就是Acitivity上的Root View，即

 @Override
protected void onCreate(Bundle savedInstanceState) 
 {
 ...
 ...
 ...
 setContentView(root);
 还有就是1 中的 创建AdView
 }
