我有一个4 * 4网格的ImageViews排列在GridLayout中。
当我更新ImageViews时,网格中所有项目的比例与所提供的图像成比例变化,此处显示为Android图标作为基本ImageViews,以及2个棕色更新的ImageViews。
当我尝试更新大量的ImageViews时,这种情况发生了极端情况,并且一切都在屏幕外移动
每个ImageView都以相同的方式初始化(行列位置除外)
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="@mipmap/ic_launcher"
android:id="@+id/tileImg00"
android:layout_row="0"
android:layout_column="0"
android:layout_columnWeight="1"
android:layout_rowWeight="1"
android:contentDescription="@string/img_descriptor" />
如何修复ImageView的大小?我想设置图像,缩放它以使其适合设计蓝图中显示的ImageView的边界,并确保图像不允许ImageView打破网格的原始方向。
