Question

我在这里问，因为我无法在我的应用中添加instertital广告。当我把代码放在保存的实例下面时，我得到了20个错误。我有其他的应用程序，我从来没有遇到过问题，但现在我无法做到。

在Toast部分（广告代码下方）中出现此错误：此行有多个标记 - 令牌上的语法错误＆＃34;（＆＃34;，无效的VariableDeclaratorId - 令牌上的语法错误，删除这些令牌 - 令牌上的语法错误＆＃34; makeText＆＃34;，预期后的标识符这个标记 - 令牌上的语法错误＆＃34;）＆＃34;，删除此令牌

下面吐司，在btnSwitch上我得到这个错误：此行有多个标记 - 缺少方法的返回类型 - 令牌上的语法错误＆＃34;。＆＃34;，...预期 - 令牌上的语法错误＆＃34;）＆＃34;，{此令牌后的预期 - 令牌上的语法错误＆＃34; btnSwitch＆＃34;，预期后的VariableDeclaratorId 这个标记 - 语法错误，插入＆＃34 ;;＆＃34;完成FieldDeclaration

包lol.flashlight;

然后在这里：

ImageView Facebook = (ImageView) findViewById(R.id.imageView3);
    Facebook.setOnClickListener(new View.OnClickListener() {
                            public void onClick(View view) {

我收到此错误：此行有多个标记 - 语法错误，插入＆＃34;}＆＃34;去完成 MethodBody - 语法错误，插入＆＃34;）＆＃34;去完成表达 - 语法错误，插入＆＃34 ;;＆＃34;去完成声明 - 语法错误，插入＆＃34;}＆＃34;去完成 ClassBody

...我收到更多错误我试图把它放在最后但是无论如何我得到这些错误，我该怎么办？如果你想检查我的完整代码：

这里的导入是错误的，因为它们是从旧版admob 导入的：

import com.google.ads.Ad;
import com.google.ads.AdListener;
import com.google.ads.AdRequest;
import com.google.ads.AdRequest.ErrorCode;
import com.google.ads.InterstitialAd;

您必须从.gms Google Play服务Admob 导入：

import com.google.android.gms.ads.*

另请注意，示例中Toast.makeText(MainActivity.this, "Touch amumu's body to play a sound!", Toast.LENGTH_SHORT).show();下面的所有代码都是在任何方法之外（！）..这会导致数十个编译错误。 ==＆GT;将该代码移动到某种方法
