文本视图未移动到约束布局中的起始位置 由于某种原因，我的约束布局>代码> 文本视图< /代码>根本不会移动，卡在中间。如何将它们移动到左/起始位置？我尝试了以下方法，但都不起作用。还有什么好用的吗 android:gravity=“start” app:flow\u horizontalBias=“0.0”

但我认为在你的布局中，你添加了太多的限制。对于每个textView，您不必将约束设置为卡片视图的末尾。如果您只添加一个布局，它将自动启动。
您可以添加整个布局吗？@I抱歉，我忘了这一点。我现在已经添加了。这个文本视图必须垂直扩展，否则你只想让它们像现在一样在高度上？@iknow我想让我的文本在左边，而不是中间。你能添加整个布局吗？@iknow抱歉，忘了这一点。我现在添加了它。这个文本视图必须垂直扩展，否则你只想让它们像现在一样在高度上？@iknow我想让我的文本在左边，而不是在中间，就像我想让我的文本在左边，而不是在中间现在如果这是你想要的结果？我想让我的文本在左边，而不是在中间现在，如果这是你想要的结果？
