更改下划线的颜色

普通来说,对当前页面/window设置主题,主题里设置colorAccent就是Edittext的取色
如果要与当前主题颜色不同,则采用单独主题,内部覆盖两个属性:
参考:
http://www.codexpedia.com/android/setting-edittext-underline-color-in-android/

<style name="MyEditTextStyle2" parent="Widget.AppCompat.EditText">
    <item name="colorControlActivated">#dc8f41</item>
    <item name="colorControlNormal">#d11472</item>
</style>

更改光标颜色

主要是适配华为手机,需要在代码里发射并复写属性:

public class CommonEditText extends android.support.v7.widget.AppCompatEditText {
    public CommonEditText(Context context) {
        this(context,null);
    }

    public CommonEditText(Context context, AttributeSet attrs) {
        super(context, attrs);
        modifyCursorDrawable(context,attrs);
    }

    public CommonEditText(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        modifyCursorDrawable(context,attrs);
    }

    protected void modifyCursorDrawable(Context context, AttributeSet attrs){
        TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.CommonEditText);
        int drawable = a.getResourceId(R.styleable.CommonEditText_textCursorDrawable,R.drawable.et_cursor_aku);
        if(drawable != 0) {
            try {

                Field setCursor = TextView.class.getDeclaredField("mCursorDrawableRes");
                setCursor.setAccessible(true);
                setCursor.set(this, drawable);

            } catch (IllegalAccessException e) {
                e.printStackTrace();
            } catch (NoSuchFieldException e) {
                e.printStackTrace();
            }
        }
        a.recycle();
    }
}

样式:

<!--edittext 通用样式-->
    <style name="commonEditTextStyle">
        <item name="android:textCursorDrawable">@drawable/et_cursor_aku</item>
        <item name="android:paddingLeft">5dp</item>
        <item name="android:paddingRight">5dp</item>
        <item name="android:cursorVisible">true</item>
    </style>



//et_cursor_aku:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <size android:width="@dimen/et_cursor_width"/>
    <solid android:color="@color/et_cursor"/><!--#f87e32-->

</shape>
