        super.onCreate(savedInstanceState);
        //GameView gView = new GameView(this);
        GameView gView = new GameView(this);
        gView.setKeepScreenOn(true);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(
                WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        MobileAds.initialize(getApplicationContext(), "ca-app-pub-0664573200302260/332653322424");
        LinearLayout layout = new LinearLayout(this);
        layout.setOrientation(LinearLayout.VERTICAL);

//Additionally to adjust the position to Bottom
        layout.setGravity(Gravity.BOTTOM);



// Create a banner ad
        mAdView = new AdView(this);
        mAdView.setVisibility(View.VISIBLE);
        mAdView.setAdSize(AdSize.BANNER);
        mAdView.setAdUnitId("ca-app-pub-3940256099942544/6300978111");

// Create an ad request.
        AdRequest.Builder adRequestBuilder = new AdRequest.Builder();


// Optionally populate the ad request builder.
        adRequestBuilder.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);

// Add the AdView to the view hierarchy.
        layout.addView(mAdView);

// Start loading the ad.
        mAdView.loadAd(adRequestBuilder.build());

        setContentView(layout);


    }
}

Your_View.getLayoutParams().height  = getResources().getDimensionPixelSize(R.dimen.Whatever_Height);

Your_View.getLayoutParams().width  = getResources().getDimensionPixelSize(R.dimen.Whatever_Height);

添加您所需的高度和宽度（以十分之一为单位）。类似xml的：

<dimen name="dimension10">10dp</dimen>

所以你可以在R.dimen.dimension10中使用它
