Question

我遇到某些文字观点的问题，这些观点固执地不会改变颜色。我不确定为什么它不起作用。

我的颜色是resource/colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#FDCDB2</color>
    <color name="colorPrimaryDark">#E2896B</color>
    <color name="colorAccent">#FF4081</color>
    <color name="mainBackground">#F6F5F5</color>
</resources>

我尝试过对layout.xml文件中的颜色进行硬编码以及动态设置颜色：

    descriptionHeader.setTextColor(getResources().getColor(R.color.colorPrimaryDark));

和

    android:textColor="@color/colorPrimaryDark"

在图像中注意带有棕色色调的文本，即所需的颜色。 “描述”，它的正文和“说明”决定只是一个浅灰色

下面是我的布局代码：

<?xml version="1.0" encoding="utf-8"?>

    <android.support.v4.widget.NestedScrollView

Answer 1

弄清楚发生了什么：

在带有颜色问题的文字视图中，我正在使用

android:hint="@string/brew_method_description

而不是

android:text="@string/brew_method_description

切换设置实际文本启用了颜色更改。

为什么TextView中的文本没有改变颜色？
