安卓系统中InputTextLayout setError()方法不起作用
安卓系统中InputTextLayout setError()方法不起作用
提问于 2016-02-10 19:10:06
我设计了一个自定义的InputTextLayout，其中包含一个自定义的Edittext.This自定义编辑器文本扩展了"AppCompatEdittext“。另外，我的MainActivity扩展了AppCompatActivity。但是我仍然不能使用TextInputLayout显示错误消息。下面是我从各种文件中摘录的代码片段。
main.xml
<android.support.design.widget.TextInputLayout
android:id="@+id/last_name_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@id/first_name_layout"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp"
android:layout_marginTop="12dp"
android:background="@drawable/grey_button_normal"
android:hint="Last name"
android:minHeight="48dp"
android:paddingTop="3dp"
android:theme="@style/TextLabel">
<com.feebite.widgets.StyleableEditText
android:id="@+id/lastname_edittext"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_gravity="center_vertical"
android:background="@android:color/transparent"
android:gravity="center_vertical"
android:minHeight="48dp"
android:nextFocusDown="@+id/email_edittext"
android:paddingBottom="10dp"
android:paddingLeft="15dp"
android:singleLine="true"
android:textColor="@color/darkish_grey"
android:textColorHint="@color/darkish_grey"
android:textCursorDrawable="@null"
android:textSize="18sp" />
</android.support.design.widget.TextInputLayout>MainActivity.java
mLastNameLayout = (TextInputLayout) findViewById(R.id.last_name_layout);
mLastNameLayout.setHint("Last name");
mLastNameLayout.setErrorEnabled(true);来自styles.xml的自定义主题
<style name="TextLabel" parent="TextAppearance.AppCompat">
<!-- Hint color and label color in FALSE state -->
<item name="android:textColorHint">@color/darkish_grey</item>
<!-- Label color in TRUE state and bar color FALSE and TRUE State -->
<item name="colorAccent">@color/darkish_grey</item>
<item name="colorControlNormal">@color/darkish_grey</item>
<item name="colorControlActivated">@color/dark_pink</item>
</style>并显示错误。

尝试同时设置以下属性：
<item name="android:textColorHighlight">@color/Your color</item>
<item name="android:textColorLink">@color/Your color</item>Stack Overflow用户

有完全相同的问题，但没有一个答案得到解决。真正起作用的是删除了这个：parent="TextAppearance.AppCompat"

您可以为TextInputLayout使用不同的属性，例如
app:errorEnabled：切换错误可见性，并在不应显示任何错误时使用空字符串。我们也可以使用setError(null).app:errorTextAppearance：文本外观来表示错误文本。我们可以使用类似于@style/TextInputLayout.ErrorText.app:hintTextAppearance：Text外观的内容作为提示文本。我们可以使用像@style/TextInputLayout.HintText.
这样的东西
其中：
<style name="TextInputLayout"/>
<style name="TextInputLayout.ErrorText">
<item name="textColorError">#FFD50000</item>
</style>
<style name="TextInputLayout.HintText">
<item name="android:textColor">?attr/colorPrimary</item>
<item name="android:textSize">@dimen/text_tiny_size</item>
</style>你要找的是app:errorTextAppearance。您还可以使用android:theme使容器的小提示( EditText )继承您的应用程序主题配置。
