自定义字体EditText焦点

Question

我在棒棒糖设备的样式中使用了棒棒糖的新功能，例如 coloraccent，colorPrimary 。

styles.xml

<resources>

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/material_teal500</item>
    <item name="colorPrimaryDark">@color/material_teal600</item>
    <item name="colorAccent">@color/material_white</item>
</style>

现在我想为textview，edittext和button创建自定义字体。 在风格上我使用coloraccent为白色。所以在edittext的焦点上应该会出现白色。有关默认的edittext焦点，请参见下图。这很好。

但每当我创建自定义字体edittext时，焦点行为就不同了。 它没有显示白色。相反，它以黑色显示。请参阅下图，了解我的自定义电子邮件的edittext行为。

这是我的自定义edittext字体类。

                throw new IllegalArgumentException("Unknown `typeface` attribute value " + typefaceValue);
        }
        return typeface;
    }

}

我在xml中使用了自定义类型的face，如下所示。

<appname.utilities.TypefaceEditText
        android:id="@+id/editText2"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:layout_margin="@dimen/ten_dp"
        custom:typeface="roboto_light"
        android:ems="10"
        android:hint="@string/user_email"
        android:inputType="textEmailAddress"
        android:textColor="@color/material_grey200"
        android:textColorHint="@color/material_grey200" />

我如何解决这个问题！任何的想法？我知道我可以在java类文件中实现自定义字体。但我想以这种方式实施。在我自己的自定义编辑文本中，我也希望显示相同的强调色。先谢谢！

Answer 1

我发现了！对于应用colorAccent，只需从中扩展自定义的EditText类 android.support.v7.widget.AppCompatEditText

Answer 2

这适用于我的自定义edittext，让我们为您的情况尝试此代码。在Activity's布局（edittext的布局）中添加这两行XML：

<LinearLayout
    android:focusable="true"
    android:focusableInTouchMode="false"
    />

Answer 3

尝试这样的事情：

editText2.setOnTouchListener(new OnTouchListener() 
  {
    @Override
    public boolean onTouch(View v, MotionEvent event) 
     {
         editText2.setFocusableInTouchMode(true);
         return false;
     }
  });
