无法使ColorStateList膨胀,将其留给框架java.lang.UnsupportedOperationException:无法转换为颜色:type = 0x2

Question

我有一个登录部分,我使用TextInputLayout作为电子邮件和密码.两者都是一样的.我还使用数据绑定来显示错误消息.

如果它应显示错误提示,则错误发生在API <20上.

    @Override
    public void showEmailError() {
        inputLayoutEmail.setError(sInvalidEmail);
    }

xml布局:

        <android.support.design.widget.TextInputLayout
            android:id="@+id/til_email"
            android:layout_height="wrap_content"
            android:layout_width="match_parent"
            android:layout_marginLeft="@dimen/default_margin_16dp"
            android:layout_marginRight="@dimen/default_margin_16dp"
            android:layout_marginTop="16dp"
            android:layout_below="@id/login_img_logo"
            android:layout_centerHorizontal="true"
            android:textColorHint="@color/gray"
            android:background="@drawable/login_edittext"
            android:errorEnabled="@{viewmodel.obEmailErrorVisibility}"
            >

            <EditText
                android:id="@+id/et_login"
                android:layout_height="@dimen/login_view_height"
                android:layout_width="@dimen/login_view_width"
                android:inputType="text"
                android:maxLength="50"
                android:hint="@string/activity_login_hint_email"
                android:text="@={viewmodel.email}"
                android:textColor="@color/black"
                android:textColorHint="@color/gray"
                android:paddingLeft="@dimen/default_margin_16dp"
                android:enabled="@{viewmodel.obIsEmailFieldEnabled}"
                />

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

        <android.support.design.widget.TextInputLayout
            android:id="@+id/til_password"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginLeft="@dimen/default_margin_16dp"
            android:layout_marginRight="@dimen/default_margin_16dp"
            android:layout_marginTop="@dimen/default_margin_8dp"
            android:layout_below="@id/til_email"
            android:layout_centerHorizontal="true"
            android:textColorHint="@color/gray"
            android:background="@drawable/login_edittext"
            android:errorEnabled="@{viewmodel.obPassErrorVisibility}"
            >

            <EditText
                android:id="@+id/et_password"
                android:layout_width="@dimen/login_view_width"
                android:layout_height="@dimen/login_view_height"
                android:hint="@string/activity_login_hint_password"
                android:maxLength="50"
                android:inputType="textPassword"
                android:text="@={viewmodel.password}"
                android:textColor="@color/black"
                android:textColorHint="@color/gray"
                android:paddingLeft="@dimen/default_margin_16dp"
                android:enabled="@{viewmodel.obIsPassFieldEnabled}"
                />

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

作为背景我使用 login_edittext.xml

<solid android:color="@color/white" />

<corners
    android:radius="@dimen/login_edittext_radius"
    />

我检查了类似的答案,但大多数都与样式有关

无法转换为颜色:在片段中展开布局时类型= 0x2错误,但仅限于三星Galaxy和Note 4

Answer 1

所以,我已经完成了适用于我的这个解决方案.

To TextInputLayout添加此字符串

app:errorTextAppearance="@style/MyAppTheme.TextInputLayout"

并为styles.xml添加新样式

    <style name="MyAppTheme.TextInputLayout" parent="@android:style/TextAppearance">
         <item name="android:textColor">@color/red</item>
    </style>
