OnCreate中的AdMob广告可以,但是如果您返回活动状态则消失,为什么? [英] AdMob ad in onCreate OK, but disappears if you return to activity, why?
问题描述
我已将广告添加到我的活动中,如下所示:
I've added an ad to my activity like follows :
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.languageselection);
// Create the adView
adView = new AdView(this, AdSize.BANNER, MY_AD_UNIT_ID);
// Lookup your LinearLayout assuming it�s been given
// the attribute android:id="@+id/mainLayout"
LinearLayout layout = (LinearLayout) findViewById(R.id.ad_layout);
// Add the adView to it
layout.addView(adView);
// Initiate a generic request to load it with an ad
adView.loadAd(new AdRequest());
}
加载广告的罚款。但是,如果我单击菜单按钮并修改一些共享的首选项并返回,则广告消失了,并且没有重新填充。
That loads the ad fine. However if I click the menu button and modify some shared preferences and return, the ad has disappeared and doesn't get re-filled.
这就是我从中导航的方式我的活动中,请注意我没有在活动中结束,所以在onCreate中创建的广告应该仍然存在吗?
This is how I navigate out from my activity, notice that I don't call finish on the activity, so the ad that was created in the onCreate should still be there?
@Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.aboutme:
startActivity(new Intent(this, About.class));
return true;
case R.id.help:
startActivity(new Intent(this, Help.class));
return true;
case R.id.preferences:
startActivity(new Intent(this, EditPreferences.class));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
如何确保广告不会丢失如果我离开活动并返回?
How can I ensure an ad doesn't get lost if I navigate away from the activity and return?
推荐答案
我个人在onStart()中创建了一个新的AdRequest:
Personally I create a new AdRequest in onStart():
public void onStart() {
super.onStart();
if(adView != null) {
adView.loadAd(new AdRequest());
}
}
