未加载广告时使用空间android

My Activity file is given below -

推荐答案

保持可见性

LinearLayout layout = (LinearLayout) findViewById(R.id.LinearLayout1);

即您最初将 Adview 添加到 View.GONE 的布局，因此它不会占用任何空间.

AdListener googleAdListener = new AdListener()
{

    @Override
    public void onAdLoaded()
    {
        super.onAdLoaded();
        try
        {
            (LinearLayout) findViewById(R.id.LinearLayout1).setVisibility(View.VISIBLE);
        }
        catch (Exception e)
        {
            Logger.LogException(e);
        }
    }
};

adView.setAdListener(googleAdListener);
