布局如下：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <TextView
        style="@style/TitleStyle"
        android:background="#f00"
        android:text="设置密码"
        />

    <EditText
        android:id="@+id/et_set_psd"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="设置密码"
        />

    <EditText
        android:id="@+id/et_confirm_psd"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="确认密码"
        />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <Button
            android:id="@+id/bt_submit"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="确认" />

        <Button
            android:id="@+id/bt_cancel"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:text="取消" />
    </LinearLayout>

</LinearLayout>

其中TitleStyle的代码如下：

<resources>
    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style name="AppBaseTheme" parent="android:Theme.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">

        <!-- 在去头的同时还保持高版本的样式主题 -->
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
        <item name="android:windowNoTitle">true</item>
    </style>

    <style name="TitleStyle">
        <item name="android:gravity">center</item>
        <item name="android:textSize">20sp</item>
        <item name="android:textColor">#000</item>
        <item name="android:padding">10dp</item>
        <item name="android:background">#0f0</item>
        <item name="android:layout_width">match_parent</item>
        <item name="android:layout_height">wrap_content</item>
    </style>

</resources>
