如何防止TextView调整父级LinearLayout的大小-Android
[英]How to prevent a TextView resize the parent LinearLayout - Android
问题描述
I have a LinearLayout that covers the entire width of the screen, inside I have a random number of TextView (7 in this example). 
我有一个LinearLayout可以覆盖屏幕的整个宽度，里面有一个随机数的TextView （在此示例中为7）。 I want all the TextView are the same size, so I put the attribute android:layout_weight="1" in each. 我希望所有TextView的大小均相同，因此我将android:layout_weight="1"放入其中。
When there is not text in the TextView everything works fine: 当TextView中没有文本时，一切正常：
but when I add the text corresponding to each TextView , the size of Textview change, not keep the weight and resize the LinearLayout 但是当我添加与每个TextView对应的文本时， Textview的大小Textview更改，而不是保持权重并调整LinearLayout大小
This is only part of the design of my Activity, so I recreated it in a new xml to see if the error persists. 这只是我的Activity设计的一部分，因此我在新的xml中重新创建了它，以查看错误是否仍然存在。 And I have noticed that this only happens when the LinearLayout is inside of a HorizontalScrollView 而且我注意到只有在LinearLayout位于HorizontalScrollView内时才会发生这种情况
When it is not, I get the expected result: 如果不是，我会得到预期的结果：
My xml: 我的xml：
