我在Android 3+，我想提示添加到我的编辑文本部件。我尝试添加了提示布局如下...

I am on Android 3+ and I am trying to add hints to my edit text widgets. I tried adding the hint to the layout as follows...

<EditText
        android:id="@+id/bar_name"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:inputType="text"
        android:hint="@string/bar_name_hint"
        android:imeOptions="actionNext"
        />

但是，当我专注于文本框中写入了提示，而不是暗示消失。

But when I focus on the Text box it writes over the hint instead of the hint disappearing.

我发现添加的onfocus监听器的EditText文件，但我想避免编程这样做。该职位也低于使用选择提及，但我无法找到如何做到这一点的文档。

I found documentation on adding a onFocus listener to the EditText, but I would like to avoid doing this programatically. The post below also mentioned using selectors but I can't find documentation on how to do that.

那么，什么是处理这个的最佳方式？

So what is the best way to handle this?

推荐答案

由于某些原因，我有活动和碎片布局设置两次。在活动的onCreate：

For some reason, I had the activity and fragment layout set twice. On Activity onCreate:

protected void onCreate(Bundle savedInstanceState) {
setContentView(R.layout.edit_consumption);

和片段onCreateView：

and on the fragment onCreateView:

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.edit_consumption, null);

所以我不得不2层的布局。我只需要在活动的onCreate删除布局来解决这个问题。也许你有同样的问题。

So I had 2 layers of layout. I only had to remove that layout from the Activity onCreate to fix the problem. Maybe you have the same problem.
