Question

如图所示,文字不在墙上.这是一个奇怪的行为,我认为这是一个错误

如何让TextView被叫street_name文本不在屏幕外？我使用MaterialDrawer,但我不认为这与此有任何关系.设备是三星Note 4有Android 6.0.1.com.android.support.constraint:constraint-layout:1.0.2在Android Studio 2.3.3中使用ConstraintLayout版本

Answer 1

设置android:layout_width="0dp"为street_name.这将使它匹配约束并应将其保持在边界内.

不工作？street_name被guideline30at 限制在右边395dp.是395dp关闭屏幕的右侧？

Answer 2

添加layconstraintEnd_toEndOf
app:layout_constraintEnd_toEndOf ="parent"
和width 0dp
android:layout_width ="0dp"

单独设置宽度0dp将不起作用
