match_parent并且未按预期填充-Android / XML

我在listView中有一个YoutubeThumbnail / ImageView,我想填充/拉伸到屏幕边缘：

        <com.example.project.ui.widget.VideosListView
            android:id="@+id/videosListView"
            android:adjustViewBounds="true"
            android:scaleType="fitXY"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
        </LinearLayout>

和

 <com.example.project.ui.widget.UrlImageView
        android:id="@+id/userVideoThumbImageView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:adjustViewBounds="true"
        android:background="@android:color/black"
        android:scaleType="fitXY"
        android:clickable="false"
        android:contentDescription="YouTube video thumbnail"
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:gravity="center"
        android:src="@drawable/ic_launcher" />

当前似乎没有这样做,并且在某些设备上,缩略图看起来很小.

我不确定自己做错了什么-任何输入都会受到赞赏.

解决方法:

如果要扩展ImageView,请尝试应用此方法：

android:scaleType="fitXY"

或在Javacode中

imageView.setScaleType(ScaleType.FIT_XY);

2)应用上述代码,例如：

<com.example.project.ui.widget.UrlImageView
        android:id="@+id/userVideoThumbImageView"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:adjustViewBounds="false"
        android:background="@android:color/black"
        android:clickable="false"
        android:contentDescription="YouTube video thumbnail"
        android:focusable="false"
        android:scaleType="fitXY"
        android:focusableInTouchMode="false"
        android:gravity="center"
        android:src="@drawable/ic_launcher" />

编辑已更改：

android:adjustViewBounds="true"

至

android:adjustViewBounds="false"
