android - 如何调整滚动视图的大小以使所有内容都适合屏幕？

问题描述

我不太确定我在这里做错了什么。

我希望广告位于底部以便显示在屏幕上，并且我希望缩小scrollview或缩小顶层linearlayout以便所有内容都可以显示在屏幕上。

                app:layout_constraintBottom_toBottomOf="parent">
        </com.google.android.gms.ads.AdView>

    </LinearLayout>

</android.support.constraint.ConstraintLayout>

在我添加之前这是有效AdView的，但我不太确定我在哪里搞砸了。

在这种情况下，@string/test_value只是长的虚拟文本来强制scrollview变大：

    Ads are an effective and easy way to earn revenue from your apps. Google AdMob is
    a smart monetization platform for apps that helps you to maximize revenue from ads and in-app purchases. More
    than 1 million apps use Google AdMob to generate a reliable revenue stream, with more than $1 billion paid to
    developers. All you need to do is sign up for Google AdMob, and then use the Google Mobile Ads SDK to place ads
    in your app with just a few lines of code. You get paid quickly in your local currency (where available), with
    no wire fees charged by Google AdMob. Also, Google AdMob’s integration with Google Play services pushes
    automatic performance improvements to Android apps without additional SDK changes.Well-placed, well-targeted ads
    in apps, particularly free apps, can achieve good click-through rates while preserving the app’s user
    experience. It’s easy to add the code to deliver ads, and Google AdMob takes care of the rest: finding and
    delivering relevant ads to your app from any of Google’s advertiser demand across Google AdMob, Google Ads, and
    the Authorized buyers. This range of advertising sources—coupled with free, industry-leading mediation—achieves
    high CPMs and excellent fill rates, automatically helping to improve your earnings.

不wrap_content应该调整大小scrollview还是我在某处的布局中犯了错误？

解决方案

您可以尝试此 xml 代码：我正在使用带有属性匹配约束的约束布局，ScrollView它AdView允许ScrollView根据其链接约束对其进行自我设置。
