我使用appcompat v7,以获得在Android 5和更少的外观一致。它运行得相当好。但是,我不知道如何更改EditTexts的底线颜色和强调色。这可能吗?

我试图定义一个自定义android:editTextStyle(参见下面),但我只成功地改变了完整的背景色或文本颜色,但不是底线或强调色。是否有要使用的特定属性值?我必须通过android:background属性使用自定义可绘制图像吗?在六边形中不能指定颜色吗?

 <style name="Theme.App.Base" parent="Theme.AppCompat.Light.DarkActionBar">
     <item name="android:editTextStyle">@style/Widget.App.EditText</item>
 </style>

 <style name="Widget.App.EditText" parent="Widget.AppCompat.EditText">
     ???
 </style>

根据android API 21的来源,材料设计的EditTexts似乎使用colorControlActivated和colorControlNormal。因此,我尝试在前面的样式定义中覆盖这些属性,但没有效果。可能appcompat不使用它。不幸的是,我找不到最新版本的appcompat材料设计的来源。

这个问题完全把我难住了。我已经在这个线程中尝试了所有的东西,但无论我做什么,我都不能改变下划线的颜色,除了默认的蓝色。

I finally figured out what was going on. I was (incorrectly) using android.widget.EditText when making a new instance (but the rest of my components were from the appcompat library). I should have used android.support.v7.widget.AppCompatEditText. I replaced new EditText(this) with new AppCompatEditText(this) and the problem was instantly solved. It turns out, if you are actually using AppCompatEditText, it will just respect the accentColor from your theme (as mentioned in several comments above) and no additional configuration is necessary.

公认的答案是更基于每个样式的东西,但最有效的做法是在你的AppTheme样式中添加colorAccent属性,像这样:

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorAccent">@color/colorAccent</item>
        <item name="android:editTextStyle">@style/EditTextStyle</item>
</style>

<style name="EditTextStyle" parent="Widget.AppCompat.EditText"/>

colorAccent属性用于在整个应用程序中为小部件着色,因此应该用于一致性

以下是API < 21及以上的解决方案

Drawable drawable = yourEditText.getBackground(); // get current EditText drawable 
drawable.setColorFilter(Color.GREEN, PorterDuff.Mode.SRC_ATOP); // change the drawable color

if(Build.VERSION.SDK_INT > 16) {
    yourEditText.setBackground(drawable); // set the new drawable to EditText
}else{
    yourEditText.setBackgroundDrawable(drawable); // use setBackgroundDrawable because setBackground required API 16
}

希望能有所帮助

Use:

<EditText
    app:backgroundTint="@color/blue"/>

这将支持前棒棒糖设备不仅+21

这是所有api中最简单、最有效/可重用/有效的 创建一个自定义EditText类,如下所示:

public class EditText extends android.widget.EditText {
    public EditText(Context context) {
        super(context);
        init();
    }

    public EditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        init();
    }

    public EditText(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init();
    }

    private void init() {
        getBackground().mutate().setColorFilter(ContextCompat.getColor(getContext(), R.color.colorAccent), PorterDuff.Mode.SRC_ATOP);
    }
}

然后这样使用它:

 <company.com.app.EditText
        android:layout_width="200dp"
        android:layout_height="wrap_content"/>
