In order for centering of hint text to work with EditText you have to make sure android:ellipsize="start" is defined. I don't know why this makes it work, but it does.
为了使提示文本居中以与 EditText 一起使用，您必须确保定义了 android:ellipsize="start"。我不知道为什么这使它起作用，但确实如此。
Example pulled from personal code:
从个人代码中提取的示例：
<EditText
android:id="@+id/player2Name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:ellipsize="start"
android:gravity="center_horizontal"
android:hint="@string/player2_name"
android:inputType="textCapWords|textPersonName"
android:singleLine="true" />

Actually, android:gravity="center_horizontal"creates the centering effect you're looking for. Similarly, you can use android:gravity="start"to put hint text at the beginning of the EditText view, and so on.
实际上，android:gravity="center_horizontal"创建您正在寻找的居中效果。同样，您可以使用android:gravity="start"将提示文本放在 EditText 视图的开头，依此类推。

I used this code in every circumstances, and it works perfectly without using android:ellipsize="start"to make a hint in center.
我在任何情况下都使用了这段代码，它在不使用android:ellipsize="start" 的情况下完美地工作。
<EditText
android:id="@+id/player2Name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:hint="robi"
android:inputType="text" />

Unfortunately, neither answer helped me aligning hint, written in LTR language, while the layout orientation was RTL. I needed such layout in a kind of translation application to make overlay icons not interfere with RTL text. But this trick didn't work with hints while there was no any text yet (icons appeared above the hint) and I came to the following java solution to layout problem:
不幸的是，这两个答案都没有帮助我对齐用 LTR 语言编写的提示，而布局方向是 RTL。我需要在一种翻译应用程序中进行这样的布局，以使覆盖图标不会干扰 RTL 文本。但是这个技巧不适用于提示，而还没有任何文本（提示上方出现图标），我来到了以下布局问题的java解决方案：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
. . .
if (isRightToLeft()){
EditText guess = (EditText) rootView.findViewById(android.R.id.text1);
CharSequence hint = "\u200F" + guess.getHint();
guess.setHint(hint);
}
. . .
}
The trick was in right-to-left mark to prepend a left-to-right string. And it seems to work, but does anyone know a more elegant solution?
诀窍是在从右到左的标记中添加从左到右的字符串。它似乎有效，但有人知道更优雅的解决方案吗？
