推荐答案

您可能已经创建了android.inputmethodservice.KeyboardView.xml布局资源文件

You may have created a android.inputmethodservice.KeyboardView.xml layout resource file

使用android:keyBackground="#FF419F3C"

<?xml version="1.0" encoding="utf-8"?>
<android.inputmethodservice.KeyboardView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="wrap_content"
    android:id="@+id/keyboard"
    android:labelTextSize="20dp"
    android:background="@color/colorTrybg"        
    android:keyTextColor="@color/colorTrykey"
              <!-- This one -->
    android:keyBackground="#FFFFFF"
    android:layout_alignParentBottom="true"
    android:keyPreviewLayout="@layout/preview">
</android.inputmethodservice.KeyboardView>
