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>
