在Android M上将error设置为TextInputLayout后更改EditText背景的问题

Question

<android.support.design.widget.TextInputLayout
android:id="@+id/input_layout_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
app:errorTextAppearance="@style/ErrorText">

<EditText
    android:id="@+id/input_name"
    android:layout_width="fill_parent"
    android:layout_height="40dp"
    android:background="@drawable/edittext_selector"
    android:hint="@string/hint_name"
    android:imeOptions="actionNext"
    android:inputType="textEmailAddress" />

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

if (inputName.getText().toString().trim().isEmpty()) {
    inputLayoutName.setErrorEnabled(true);
    inputLayoutName.setError("Errorrroror");
    inputName.setBackgroundResource(R.drawable.edittext_red_focused);
    requestFocus(inputName);
    return false;
} else {
    inputName.setBackgroundResource(R.drawable.edittext_selector);
    inputLayoutName.setErrorEnabled(false);
}

return true;

下面是错误的资源文件

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape>
<solid android:color="@color/sale_color" />
</shape>
</item>

<!-- main color -->
<item
android:bottom="1.0dp"
android:left="1.0dp"
android:right="1.0dp">
<shape>
<solid android:color="@android:color/white" />
</shape>
</item>

<!-- draw another block to cut-off the left and right bars -->
<item android:bottom="1.0dp">
<shape>
<solid android:color="@android:color/white" />
</shape>
</item>
</layer-list>

您可以使用自定义Edittext背景来实现这一点。

创建可绘制的选择器，如下所示，

<item>
    <shape android:shape="rectangle">
        <solid android:color="@android:color/transparent" />
    </shape>
</item>

<item
    android:left="-2dp"
    android:right="-2dp"
    android:top="-2dp">
    <shape>
        <solid android:color="@android:color/transparent" />
        <stroke
            android:width="1dp"
            android:color="@color/edit_text_normal_color" />
    </shape>
</item>

<item>
    <shape android:shape="rectangle">
        <solid android:color="@android:color/transparent" />
    </shape>
</item>

<item
    android:left="-2dp"
    android:right="-2dp"
    android:top="-2dp">
    <shape>
        <solid android:color="@android:color/transparent" />
        <stroke
            android:width="1dp"
            android:color="@color/colorPrimary" />
    </shape>
</item>

<item>
    <shape android:shape="rectangle">
        <solid android:color="@android:color/transparent" />
    </shape>
</item>

<item
    android:left="-2dp"
    android:right="-2dp"
    android:top="-2dp">
    <shape>
        <solid android:color="@android:color/transparent" />
        <stroke
            android:width="1dp"
            android:color="@color/sale_color" />
    </shape>
</item>

并在运行时，当错误发生时，设置错误可提取

验证代码

private boolean validateName() {

    if (inputName.getText().toString().trim().isEmpty()) {
        inputLayoutName.setErrorEnabled(true);
        inputLayoutName.setError("Error");
        inputName.setBackgroundResource(R.drawable.edittext_red_focused);
        return false;
    } else {
        inputName.setBackgroundResource(R.drawable.edittext_selector);
        inputLayoutName.setErrorEnabled(false);
    }

    return true;
}
