ConstraintLayout layout_constraintHorizo​​ntal_bias似乎不起作用 [英] ConstraintLayout layout_constraintHorizontal_bias seems not work

问题描述

这是我的布局文件.

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <EditText
        android:layout_width="150dp"
        android:layout_height="50dp"
        android:hint="please input test content"
        android:inputType="phone"
        android:textColorHint="@android:color/holo_red_light"
        android:textSize="13sp"
        app:layout_constraintBottom_toTopOf="parent"
        app:layout_constraintRight_toLeftOf="parent" />
    <TextView
        android:layout_width="80dp"
        android:layout_height="50dp"
        android:gravity="center"
        android:text="Hello"
        android:textColor="@android:color/black"
        app:layout_constraintBottom_toTopOf="parent"
        app:layout_constraintHorizontal_bias="0.5" />
</android.support.constraint.ConstraintLayout>

下面的图片是预览视图.

Follow pic is preview view.

我想将TextView移到center_horizo​​ntal到父视图，但是layout_constraintHorizontal_bias=0.5"似乎不起作用.

I want to move TextView to center_horizontal to parent view , but layout_constraintHorizontal_bias=0.5" seems not work.

谁对此问题有想法?首先谢谢您！

Who has ideas for this problem ? Thanks for first !

        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />

    <TextView
        android:layout_width="80dp"

        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</android.support.constraint.ConstraintLayout>

要使用 bias ，您需要将其限制给任何父母.

to use bias you need to give constrained it to any parent.
