我目前正在做一个横向屏幕的特殊 xml 布局,其中存在 4 个图像,并且 2 个 LinearLayouts 彼此相邻,每个图像 2 个图像。这些 LinearLayouts 我称之为linearLayout1
和linearLayout2
.
linearLayout1
用蓝色矩形标记:
linearLayout2
用蓝色矩形标记:
如您所见,第一个使用了大约 80% 的屏幕,而第二个使用了剩余的屏幕。我当然不想要这个,我想要每个 50%。我不能使用layout_weight
,因为它已经在 LinearLayouts 本身(两个图像的定位)中使用,并且嵌套权重不利于性能。
我尝试了许多不同的变体,但我根本无法让两个 LinearLayout 各占屏幕的 50%。这是代码:
