Android Layout - layoutweight 和 weightsum [英] Android Layout - layoutweight and weightsum
问题描述
我需要用一组线性布局构建一个布局.布局必须占据屏幕的定义百分比.我需要这样做才能在所有设备中具有相似的外观.
I need to build a layout with the set of linear layouts. The layout has to occupy a defined percentage of the screen. I need to do this to have a similar look in all the devices.
我在右上角的布局中有一个 textview(绿色框).每当我在 textview 中添加一些数据时,它都会干扰整个布局,如下图 2 所示.但是当数据到达屏幕/布局的右端时,我需要让数据自动换行.
I have a textview in the top right layout (green color box ). Whenever I add some data in the textview it disturbs the entire layout as shown below in the 2nd image. But I need to have the data wraps automatically when it reaches the right end of the screen/layout.
请帮我解决这个问题.提前致谢
Please help me to resolve this. Thanks In Advance
