Question

我的表单中包含TextInputLayout和TextInputEditText。这是相关的XML：

<android.support.design.widget.TextInputLayout
        android:id="@+id/signup_til_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="@dimen/activity_horizontal_margin"
        android:hint="Name"
        app:counterEnabled="true"
        app:counterMaxLength="16"
        app:errorEnabled="true">

        <android.support.design.widget.TextInputEditText
            android:id="@+id/signup_etext_name"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:textAppearance="@style/TextAppearance.AppCompat.Small"/>
    </android.support.design.widget.TextInputLayout>

当我尝试将第17个字符输入此字段时，我的活动会因以下堆栈跟踪而崩溃：

java.lang.RuntimeException: Failed to resolve attribute at index 3
at android.content.res.TypedArray.twGetColorStateList(TypedArray.java:438)
at android.content.res.TypedArray.getColorStateList(TypedArray.java:420)
at android.widget.TextView.setTextAppearance(TextView.java:3029)
at android.support.design.widget.TextInputLayout.updateCounter(TextInputLayout.java:688)
at android.support.design.widget.TextInputLayout.access$300(TextInputLayout.java:84)
at android.support.design.widget.TextInputLayout$1.afterTextChanged(TextInputLayout.java:248)
at android.widget.TextView.sendAfterTextChanged(TextView.java:8929)

显然它与不使用AppCompat主题有关，但我已经使用了AppCompat主题：

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"/>

不确定这是否相关，但我也使用Jake Wharton的RxBinding库TextInputEditText观察此RxTextView.textChanges(nameEditText);。

Answer 1

我建议添加另外两个属性并为其添加样式。一个是app:counterTextAppearance，另一个是app:counterOverflowTextAppearance，就像这里一样，

<android.support.design.widget.TextInputLayout
  ....
  app:counterTextAppearance="@style/counterText"
  app:counterOverflowTextAppearance="@style/counterOverride">

</android.support.design.widget.TextInputLayout>

这两种风格只不过是一个android:textColor名称的项目，例如

<style name="counterText">
  <item name="android:textColor">#aa5353cc</item>
</style>

<style name="counterOverride">
  <item name="android:textColor">#ff0000</item>
</style>

请参阅完整说明here。

如果这不起作用，那么我建议按照this answer中的建议，从Theme延长Theme.Design.*。

输入超过TextInputLayout的counterMaxLength时的RuntimeException
