Android手机卫士之设置密码对话框

本文实现初次设置密码验证过程，首先实现如下效果

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>
