Question

我设计了一个包含自定义Edittext的自定义InputTextLayout。这个自定义Edittext扩展了“AppCompatEdittext”。我的MainActivity也扩展了AppCompatActivity。但是我仍然无法使用TextInputLayout显示错误消息。以下是各种文件的代码片段。

main.xml中

<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);

styles.xml中的自定义主题

<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>

显示错误。

Answer 1

尝试设置以下属性：

<item name="android:textColorHighlight">@color/Your color</item>
<item name="android:textColorLink">@color/Your color</item>

Answer 2

完全相同的问题并没有解决任何问题。真正有用的是删除它：parent="TextAppearance.AppCompat"

Answer 3

您可以在TextInputLayout中使用不同的属性，如

app:errorEnabled：切换错误可见性，并在不显示错误时使用空字符串。我们也可以使用setError（null）。
app:errorTextAppearance：错误文本的文本外观。我们可以使用@ style / TextInputLayout.ErrorText。
app:hintTextAppearance：提示文字的文字外观。我们可以使用@ style / TextInputLayout.HintText。

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>

您正在寻找的是app:errorTextAppearance。您还可以使用android:theme使容器的小EditText（提示）继承您的应用程序主题配置。
