admob之从服务上下文 Android 显示 Admob 广告

我想展示来自正在运行的服务的广告。我的服务检查剪贴板中的文本，并显示一个带有信息的弹出窗口(字典服务)。但是当我调试应用程序时，它显示错误:

Could not initialize AdView: AdView was initialized with a Context that wasn't an Activity. 

有人说没有事件上下文就无法启动。有什么解决办法吗？

我更新了下面的代码: 显示弹出窗口的代码:

    private void showCaptureWindow() { 
 
    setTextToKeywordEdit(mClipboardText); 
 
    makeDictContent(mClipboardText); 
 
    if(!mDictContentView.hasFocus()) 
        mDictContentView.requestFocus(); 
 
    if(false == bHasAddedView) 
    { 
        int bgColor = MultiDictUtils.GetBgColor(); 
        int textColor = MultiDictUtils.GetTextColor(); 
        mParentViewLayout.setBackgroundColor(bgColor); 
        mDictContentView.setBackgroundColor(bgColor); 
        mLineView0.setBackgroundColor(textColor); 
        mLineView1.setBackgroundColor(textColor); 
        mLineView2.setBackgroundColor(textColor); 
        mLineView3.setBackgroundColor(textColor); 
        mLineView4.setBackgroundColor(textColor);            
 
        updateDisplaySize(true); 
 
        mWindowParams.x = mWindow_Default_X; 
        mWindowParams.y = mWindow_Default_Y; 
 
        mWinStatus = 0; 
        mWindowResizeBtn.setImageResource(R.drawable.ic_btn_max_win); 
        // Look up the AdView as a resource and load a request. 
        adView = (AdView)mCaptureWindowLayout.findViewById(R.id.adView); 
        adView.loadAd(new AdRequest()); 
        mWindowManager.addView(mCaptureWindowLayout, mWindowParams); 
        bHasAddedView = true; 
    } 
} 

初始化服务:

    private void initService() { 
    MyLog.v(TAG, "initService()"); 
 
    mClipboardManager = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE); 
 
    if(mClipboardManager.hasText()) 
    { 
        mClipboardText = mClipboardManager.getText().toString(); 
    } 
 
    LayoutInflater factory = LayoutInflater.from(this); 
    mCaptureWindowLayout = (LinearLayout)factory.inflate(R.layout.capture_window, null); 
 
    mWindowCloseBtn = (ImageButton)mCaptureWindowLayout.findViewById(R.id.windowCloseBtn); 
    mWindowResizeBtn = (ImageButton)mCaptureWindowLayout.findViewById(R.id.windowResizeBtn); 
    mWindowMoveBtn = (ImageButton)mCaptureWindowLayout.findViewById(R.id.windowMoveBtn); 
    mWindowSchBtn = (ImageButton)mCaptureWindowLayout.findViewById(R.id.windowSchBtn); 
 
    mKeywordEdit = (EditText)mCaptureWindowLayout.findViewById(R.id.keywordTxt); 
 
    mParentViewLayout = (LinearLayout) mCaptureWindowLayout.findViewById(R.id.parentView); 
    mLineView0 = (View) mCaptureWindowLayout.findViewById(R.id.lineView0); 
    mLineView1 = (View) mCaptureWindowLayout.findViewById(R.id.lineView1); 
    mLineView2 = (View) mCaptureWindowLayout.findViewById(R.id.lineView2); 
    mLineView3 = (View) mCaptureWindowLayout.findViewById(R.id.lineView3); 
    mLineView4 = (View) mCaptureWindowLayout.findViewById(R.id.lineView4); 
    mDictContentView = (WebView)mCaptureWindowLayout.findViewById(R.id.dictContentWindow); 
    mDictContentView.setWebViewClient(new DictWebViewClient(new ServiceWebViewClientCallback())); 
 
    WebSettings webSettings = mDictContentView.getSettings(); 
    webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS); 
    webSettings.setJavaScriptEnabled(true); 
    webSettings.setSupportZoom(true); 

创建:

    @Override 
public void onCreate() { 
 
    mMultiDictUtils = new MultiDictUtils(this); 
 
    mHandler = new Handler(); 
 
    mClipboardTask = new Runnable() { 
        public void run() { 
 
            clipboardCheck(); 
 
            mHandler.postDelayed(mClipboardTask, CLIPBOARD_TIMER); 
        } 
    }; 
 
    Runnable initServiceTask = new Runnable() { 
        public void run() { 
 
            initService(); 
 
            mHandler.postDelayed(mClipboardTask, CLIPBOARD_TIMER); 
        } 
    }; 
 
    mHandler.postDelayed(initServiceTask, 5000); 
 
    super.onCreate(); 
} 

对不起，因为我不能在这里发布完整的代码。有服务检查剪贴板，然后在 View 布局中显示内容。

请您参考如下方法:

您可以在弹出窗口中显示一个广告(我假设您指的是您从服务启动的事件)。您收到的错误是因为您正在使用不是 Activity 的 Context 对象创建 AdView。传入作为弹出窗口的 Activity。
