사용자가 그것에 초점을 맞추기 전에 TextInputLayout에 EditText 힌트가 표시되지 않음
최근에 출시 된 Android 디자인 지원 라이브러리 를 사용하여 EditTexts로 플로팅 레이블을 표시하고 있습니다. 하지만 UI가 렌더링 될 때 EditText의 힌트가 표시되지 않는 문제에 직면했지만 EditTexts에 초점을 맞춘 후에 힌트가 표시됩니다.
내 레이아웃은 다음과 같습니다.
<?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>
나는 또한 TextInputLayout사용 방법에 대한 힌트를 설정하려고 setHint했지만 운이 없습니다.
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());
최신 정보:
이것은 라이브러리의 버전 22.2.1에서 수정 된 버그입니다.
원래 답변 :
@shkschneider가 언급했듯이 이것은 알려진 버그 입니다. Github 사용자 @ ljubisa987은 최근 해결 방법에 대한 Gist를 게시했습니다.

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.
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.
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.
