我正在使用最近发布的Android 设计支持库来显示带有 EditTexts 的浮动标签。但是我面临的问题是在呈现 UI 时没有显示 EditText 上的提示,但是在我专注于 EditTexts 后我看到了提示。
我的布局如下:
<?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>
我也尝试为TextInputLayout
using 方法设置提示,setHint
但没有运气。
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());
