如何在TextInputLayout

Question

刚刚开始设计样式和主题应用程序。

我在EditText的{​​{1}}中有很多TextInputLayout个。

我的问题是：

• 不确定调用AppCompatActivity小部件中的行（上面的蓝线），只是将其称为“标尺”。统治者（上面看不见）如何变得可见，以及任何自定义颜色。目前，标尺仅在点击EditText时显示。
• EditText光标未显示，如何显示？
• 如何根据背景颜色和文字颜色自定义上面的“添加”按钮？
• 如何将焦点设置为最初的EditText？
• 如果EditText的提示颜色在缩小并飞到顶部之后如何改变？ （目前，蓝色。）
• 是默认的Android字体TextInputLayout吗？如何将字体更改为可用的任何内容，“真正快速”？

非常感谢任何帮助或指示。

关于TextInputLayout，为其创建一种风格

<style name="InputLayout" parent="TextAppearance.AppCompat">
        <item name="android:textSize">18sp</item>
        <item name="android:textColor">@color/white</item>
        <item name="android:textColorHint">@color/grey</item>
        <item name="colorAccent">@color/grey</item>
        <item name="colorControlNormal">@color/grey</item>
        <item name="colorControlActivated">@color/green</item>
    </style>

这使您可以灵活地设置AppCompatEditText的样式。别忘了将样式添加到TextInputLayout。

 <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/InputLayout">

        <android.support.v7.widget.AppCompatEditText
            android:id="@+id/editText"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="@string/hint" />

    </android.support.design.widget.TextInputLayout>
