这是Android Studio的错误吗? [英] Is this a bug at Android Studio?

问题描述

我使许多按钮的UI通过约束布局输入文本. 例如下面的图片.

I make UI of many buttons to input text by constraint layout. For example, the following image.

但是，我感到奇怪的是，随着我放置更多的UI并允许设置我的自适应钩子，android studio变得非常慢，有时消失了(例如，某些按钮允许在图像上方显示Disapper头行).它应该使用非常大的内存，并且猜测可用内存以计算位置并重新渲染UI. 我可以避免这种情况吗?或使用其他布局制作相同UI的替代方法.对于这个问题，我感到非常紧张，因为我不了解制作网格灵活缩放UI的最佳方法.任何技巧都可以对我有所帮助.

But,I feel strange that android studio become very slow as I put more UIs and adaptive hook allows I set, sometimes disappear(ex.some buttons' allow disapper head row above image).It should use very large memory and I guess free memory to calculate position and re-render UI. Can I avoid this situation? or Alternative way to make same UI using another layout. I'm very nervous for this problem because I can't understand the best way to make grid flexible-scaling UI.Any tips will help me.

推荐答案

我可以使用包围按钮嵌套约束视图的网格布局解决问题，这似乎是相对定位UI的最佳方法.

I could solve the problem using grid layout enclosing the buttons nested constraint view and it seem best way that relative positioning UI.
