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.一切都很好，除了 API 上的重力等于或高于 18.

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

这是我的文本视图:

<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 或更低版本上工作正常，但在 4.3 及更高版本上不起作用......它只能部分工作，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.

乐:

这个问题有没有解决办法?或者有谁知道为什么会这样?

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，有一种解决方法是将您的视图包装在 LinearLayout 中.

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

在这个线程中查看答案.

在您的情况下，固定代码应如下所示:

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>
