Question

我正在尝试将adMob集中到顶级中心。我在横向模式。我决定继续使用BANNER尺寸而不是SMART_BANNER，因为第一个支持图像。它一直显示在TOP LEFT。

我需要使用java代码在没有xml文件的情况下实现它。我正在使用RelativeLayout。

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mHandle = new Handler() {
            public void handleMessage(Message msg) {
                if ((String) msg.obj == "hide") {
                    adView.setVisibility(View.GONE);
                } else {
                    adView.setVisibility(View.VISIBLE);
                }

            }
        };

        RelativeLayout adsLayout;
        RelativeLayout.LayoutParams lp2;
        Window window;

        window = getWindow();
        adsLayout = new RelativeLayout(this);
        lp2 = new RelativeLayout.LayoutParams(
                RelativeLayout.LayoutParams.WRAP_CONTENT,
                RelativeLayout.LayoutParams.MATCH_PARENT);
        // Displays Ads at the bottom of your sketch, use Gravity.TOP to display
        // them at the top
        adsLayout.setGravity(Gravity.TOP); // TOP, BOTTOM

        adView = new AdView(this);
        adView.setAdUnitId("ca-app-pub-7026369821782045/7333385813");
        adView.setAdSize(AdSize.BANNER);
        adView.setVisibility(View.GONE);

        adsLayout.addView(adView);

        AdRequest adRequest = new AdRequest.Builder()
        .addTestDevice("2BC774A37080BC16DF211A91E61710BA")
        .build();
        adView.loadAd(adRequest);

        window.addContentView(adsLayout, lp2);
    }

    public void hideAds() {
        Message msg = new Message();
        msg.obj = "hide";
        mHandle.sendMessage(msg);
    }

    public void showAds() {
        Message msg = new Message();
        msg.obj = "show";
        mHandle.sendMessage(msg);
    }

使用它：

lp2 = new RelativeLayout.LayoutParams(
            RelativeLayout.LayoutParams.MATCH_PARENT,
            RelativeLayout.LayoutParams.WRAP_CONTENT);
lp2.addRule(RelativeLayout.ALIGN_PARENT_TOP);
lp2.addRule(RelativeLayout.CENTER_HORIZONTAL);

横幅的宽度与活动（屏幕）相同，高度将达到需要的高度。

删除 adsLayout.setGravity(Gravity.TOP);

并在adView上使用lp2，而不是布局。 adsLayout.addView(adView, lp2);

另外，您在活动中不需要Window，您可以使用setContentView(adsLayout);

在TOP-CENTER中将某些内容与RelativeLayout对齐
