如何删除添加到膨胀线性布局的视图之间不需要的空格?

Question

我正在开发一个安卓应用程序，可以在两列的可滚动视图中显示一些电影。

一切都很好，除了我在行之间有很大的空间。

我已经尝试了很多在StackOverflow中找到的东西，比如：android：adjustViewBounds="true"，将填充设置为零等等。

谁能给我开导？

这是应用程序的外观

如您所见，行之间有一个巨大的空间

我正在通过膨胀动态添加图像视图，我认为这就是问题所在。

这是我的代码：

if (i==0) {
var mImageView = findViewById<ImageView>(R.id.imageDisplay)
mImageView.setTag(movieObject)
loadImageFromUrl(movieObject.poster_url, mImageView)

}
}
}, Response.ErrorListener { error ->

})
mQueue.add(request)
}
fun showMore(view: View) {
val intent = Intent(this, MovieSelectedActivity::class.java).apply {
var movieObj : Movie = view.getTag() as Movie
putExtra(MOVIE_OBJECT_ID, movieObj.id)
putExtra(MOVIE_OBJECT_GENRES, movieObj.genres)
putExtra(MOVIE_OBJECT_POSTER_URL, movieObj.poster_url)
putExtra(MOVIE_OBJECT_RELEASE_DATE, movieObj.release_date)
putExtra(MOVIE_OBJECT_TITLE, movieObj.title)
putExtra(MOVIE_OBJECT_VOTES, movieObj.vote_average)
}
startActivity(intent)
}
fun loadImageFromUrl(url: String, mImageView: ImageView) {
Picasso.with(this).load(url).placeholder(R.mipmap.ic_launcher)
.error(R.mipmap.ic_launcher)
.into(
mImageView, null
)
}
}

下面是视图的 xml：

我发现问题出在我在主线性布局中设置的背景上。移除它后，巨大的空间消失了。

android：background="@drawable/background">
