EditText added is not a TextInputEditText. Please switch to using that class instead
I was wondering this too, Daniel Wilson gathered the documentation, but to the untrained eye it doesn't mean much. Here's what it's all about: "extract mode" is referring to the type of view that's shown when the space is too small, for example landscape on a phone. I'm using Galaxy S4 with Google Keyboard as input method editor (IME).
Landscape UI without visible IME
Based on the focus (on Description) you can see TextInputLayout
in action pushing the hint outside the editor. Nothing special here, this is what TextInputLayout
is supposed to do.
Landscape UI editing empty Name field
Editing the Name you can see that the IME doesn't give you a hint of what you're editing.
Landscape UI editing empty Description field
Editing the Description you can see that the IME gives you a hint of what you're editing.
Layout XMLs
The difference between the two fields is their type EditText
VS TextInputEditText
. The important thing here is that TextInputLayout
has the android:hint
and not the wrapped EditText, this is the case when TextInputEditText
's few lines of Java code makes a big difference.
Name field
<android.support.design.widget.TextInputLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Item Name"
>
<EditText
android:id="@+id/name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</android.support.design.widget.TextInputLayout>
Description field
<android.support.design.widget.TextInputLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Item Description"
>
<android.support.design.widget.TextInputEditText
android:id="@+id/description"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="textMultiLine"
android:minLines="4"
android:scrollbars="vertical"
/>
</android.support.design.widget.TextInputLayout>
There is no documentation for it, but the class is a regular EditText
with a single extra feature:
Using this class allows us to display a hint in the IME when in 'extract' mode.
Specifically it sets the EditorInfo.hintText
. You'll notice in the TextInputLayout
class you can specify the hint and it's appearance rather than as part of the child EditText
widget.
If you need to do that, you should use a TextInputEditText
so it pays attention to the hint info you specified in the TextInputLayout
.
They are essentially the same thing, but I think the TextInputEditText
has more features and possibly attributes. I changed to the TextInputEditText
and everything worked and looked as it did before with the standard EditText
.
