TextView重力不适用于API 18或更高版本 [英] TextView gravity not working on API 18 or higher

问题描述

我有一个与其他视图重叠的TextView.一切正常，除了API的引力等于或大于18之外.

I have an TextView wich overlaps some other view. Everything works great, except the gravity on API equal or higher than 18.

这是我的TextView:

Here is my TextView:

<TextView
    android:id="@+id/overlappingTextView"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:layout_alignBottom="@id/behindLinearLayout"
    android:layout_alignLeft="@id/behindLinearLayout"
    android:layout_alignRight="@id/behindLinearLayout"
    android:layout_alignTop="@id/behindLinearLayout"
    android:background="@drawable/overlapping_bg"
    android:gravity="center"
    android:text="Waiting for user confirmation..."
    android:textColor="@color/blue" />

重力在4.2.2或更低版本上可以正常运行，但在4.3或更高版本上则无法运行...它仅部分起作用，它居中，但只能垂直.

The gravity works ok on 4.2.2 or lower but is not working on 4.3 and higher ... It works only partially, it is centered but only vertically.

LE:

没有解决此问题的方法?还是有人知道为什么会这样?

There is no fix for this issue? Or does anyone know why this is happening?

推荐答案

这似乎是API 18+中的一个已知问题，并且存在一种变通方法，涉及将您的视图包装在LinearLayout中.

This appears to be a known issue in API 18+, and there's a workaround involving wrapping your view in a LinearLayout.

在您的情况下，固定代码应类似于:

In your case, the fixed code should look something like:

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:layout_alignBottom="@id/behindLinearLayout"
    android:layout_alignLeft="@id/behindLinearLayout"
    android:layout_alignRight="@id/behindLinearLayout"
    android:layout_alignTop="@id/behindLinearLayout"
    android:background="@drawable/overlapping_bg" >

    <TextView
        android:id="@+id/overlappingTextView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:gravity="center"
        android:text="Waiting for user confirmation..."
        android:textColor="@color/blue" />

</LinearLayout>
