Question

我想检查文本视图之间是否存在冲突，如果存在冲突，则应显示省略号，而不是使其相互冲突。

我已经尝试过this，但是它在我的机器上不起作用（可能是由于我当前使用的字体家族，空格太多）

以下是一些XML代码，（我使用的是Constraint布局）：

Answer 1

尝试在约束布局中嵌套水平线性布局。放在你的地方当前位于fontFamilyInput微调器。接下来，将fontFamilyText TextView和fontFamilyInput微调器（按此顺序）放置在线性布局内。

现在，您可以在两个子视图中使用权重来声明文本视图在屏幕上的何处停止并且微调器开始。

但是，请记住，这只是一种方法。

Answer 2

尝试将其添加到TextView MaxEms中，确定在显示省略号之前的字符数

android:ellipsize="end" 
android:maxEms="15" 
android:singleLine="true"

Android-如果文本视图之间存在冲突，请放在省略号
