I am using recently released Android Design Support Library to show floating label with EditTexts. But i am facing the problem that the Hint on the EditText is not showing when UI is rendered, but i see the Hint after i focus on the EditTexts.
My Layout is as follows:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:id="@+id/ScrollView01"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin">
<android.support.design.widget.TextInputLayout
android:id="@+id/name_et_textinputlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/activity_vertical_margin">
<EditText
android:id="@+id/FeedBackerNameET"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/feedbackname"
android:inputType="textPersonName|textCapWords" />
</android.support.design.widget.TextInputLayout>
<android.support.design.widget.TextInputLayout
android:id="@+id/email_textinputlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="@+id/FeedBackerEmailET"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/feedbackemail"
android:inputType="textEmailAddress" />
</android.support.design.widget.TextInputLayout>
<Spinner
android:id="@+id/SpinnerFeedbackType"
android:layout_width="fill_parent"
android:layout_height="48dp"
android:layout_marginTop="@dimen/activity_vertical_margin"
android:entries="@array/feedbacktypelist"
android:prompt="@string/feedbacktype" />
<android.support.design.widget.TextInputLayout
android:id="@+id/body_textinputlayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="@+id/EditTextFeedbackBody"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/feedbackbody"
android:inputType="textMultiLine|textCapSentences"
android:lines="5" />
</android.support.design.widget.TextInputLayout>
<CheckBox
android:id="@+id/CheckBoxFeedBackResponse"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/activity_vertical_margin"
android:text="@string/feedbackresponse" />
<Button
android:id="@+id/ButtonSendFeedback"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/activity_vertical_margin"
android:text="@string/feedbackbutton" />
</LinearLayout>
</ScrollView>
</FrameLayout>
<View
android:layout_width="match_parent"
android:layout_height="5dp"
android:background="@drawable/toolbar_shadow" />
</FrameLayout>
I have also tried to set hint for the TextInputLayout using method setHint but no luck.
mNameTextInputLayout = (TextInputLayout) v.findViewById(R.id.name_et_textinputlayout);
mNameTextInputLayout.setErrorEnabled(true);
mNameTextInputLayout.setHint(feedBackerNameET.getHint());
mEmailTextInputLayout = (TextInputLayout) v.findViewById(R.id.email_textinputlayout);
mEmailTextInputLayout.setErrorEnabled(true);
mEmailTextInputLayout.setHint(feedBackerEmail.getHint());
mBodyTextInputLayout = (TextInputLayout) v.findViewById(R.id.body_textinputlayout);
mBodyTextInputLayout.setErrorEnabled(true);
mBodyTextInputLayout.setHint(feedBackBody.getHint());
Update:
This is a bug that has been fixed in version 22.2.1 of the library.
Original Answer:
As mentioned by @shkschneider, this is a known bug. Github user @ljubisa987 recently posted a Gist for a workaround:
https://gist.github.com/ljubisa987/e33cd5597da07172c55d
As noted in the comments, the workaround only works on Android Lollipop and older. It does not work on the Android M Preview.
That is a known bug of the Android Design library. It has been accepted and assigned.
So you should have this fixed in the next Android Design library release.
In the meantime, you could watch the issue tracker for a hacky-fix that might get posted there, but I don't know any as of now.
And yes, it only affect Lollipop and above.
This works for me in Design Library 23.1.1:
Set the hint color in xml attributes of TextInputLayout:
<android.support.design.widget.TextInputLayout
....
android:layout_margin="15dp"
android:textColorHint="@color/hintColor"
android:layout_width="match_parent"
...
This issue is fixed in version 22.2.1
you should use android.support.v7.widget.AppCompatEditText as EditText and set android:hint like below
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.AppCompatEditText
android:id="@+id/etx_first_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="text"
android:hint="@string/hint_first_name"/>
</android.support.design.widget.TextInputLayout>
<android.support.design.widget.TextInputLayout
android:id="@+id/editText1"
android:layout_margin="15dp"
android:layout_centerVertical="true"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<AutoCompleteTextView
android:id="@+id/editText"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:singleLine="true"
android:hint="Add City" />
</android.support.design.widget.TextInputLayout>
Use this code snippet.Make sure your activity is AppCompatActivity. And dependency are also with latest versions
compile 'com.android.support:appcompat-v7:22.2.0'
compile 'com.android.support:design:22.2.0'
Update the android studio to latest version. see output here
If you are setting your EditText hint programmatically it wouldn't work! You need to set the hint on the TextInputLayout it self.
TextInputLayout textInputLayout = (TextInputLayout) findViewById(R.id.usernameTextInputLayout);
textInputLayout.setHint(getString(R.string.username_hint));
Here is the XML in case you are wondering:
<android.support.design.widget.TextInputLayout
android:id="@+id/usernameTextInputLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.AppCompatEditText
android:id="@+id/usernameEt"
android:layout_width="match_parent"
android:layout_height="@dimen/default_height"
android:layout_marginEnd="@dimen/default_margin"
android:layout_marginStart="@dimen/default_margin"
android:maxLength="@integer/username"
tools:hint="Username" />
</android.support.design.widget.TextInputLayout>
This issue is resolved in v23.0.1 of support design library. I also updated my appcompat-v7 to 23.0.1, compileSdkVersion to 23 & buildToolsVersion to 23.0.1 in build.gradle.
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
}
dependencies {
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.0.1'
}
I solved my problem with this code:
new Handler().postDelayed(
new Runnable() {
@Override
public void run() {
TextInputLayout til = (TextInputLayout) someParentView.findViewById(R.id.til);
til.setHint("Your Hint Text");
til.bringToFront();
}
}, 10);
The key here is the bringToFront. It forces the TextInputLayout to redo its drawing, which is not the same as doing invalidate(). If you are trying to display the TextInputLayout on a view that has animations or tranistions, you need to execute the above code at the end of the animation or transition. Just make sure that the code above runs on the UI thread.
Looks like this issue appears when you set onFousListener on EditText - try to extend EditText and support multiple onFocusListeners
Set hint color that contrast to the EditText background.
<item name="android:textColorHint">#FF424242</item>

How to change the floating label color of TextInputLayout
Problem solved: Goto build.gradle of ur app and check design library. compile 'com.android.support:design:22.2.1' It should be 22.2.1 or newer.
I found something different.
When setting the style for the fragment,
f1.setStyle(DialogFragment.STYLE_NO_FRAME,android.R.style.Theme_DeviceDefault_Light);
The bug was gone when I tried different Styles than "Theme_DeviceDefault_Dialog".
Give it a try.
Problem is the hint color. It becomes white when typing something. Please change the hint color or change the background color. You will see the hint while typing.
There is a simple solution to this as this worked for me
<android.support.design.widget.TextInputLayout
android:id="@+id/activity_login_til_password"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="27dp"
android:layout_marginTop="24dp"
android:padding="10dp"
app:passwordToggleEnabled="true"
app:passwordToggleTint="#000000"
app:passwordToggleDrawable="@drawable/passwordviewtoggleselector"
android:theme="@style/Base.TextAppearance.AppCompat">
<!---- add this line and theme as you need ----->
<android.support.design.widget.TextInputEditText
android:id="@+id/activity_login_et_password"
android:layout_width="match_parent"
android:layout_height="58dp"
android:hint="Password"
android:inputType="textPassword"
android:padding="10dp"
android:textColor="#f5ab3a"
android:textColorHint="#e6d2d1cf"
android:textSize="20dp" />
</android.support.design.widget.TextInputLayout>
Just add android:theme="@style/Base.TextAppearance.AppCompat" to the TextEditLayout and it should work and you can change the theme as you need.
Just add: android:hint="your_hint" for TextInputLayout.
