展示一下，没事随便写的修改密码的UI布局，代码中修改密码其实也很简单介绍下简单的实现和思路：
1.一开始想着：输入原密码   输入新密码  确认输入新密码；但是想了想为了方便大家，我就直接在登陆的时候获取服务器返回的用户名和密码，用SharedPreferences保存起来，在程序的任何地方都可以调用
2.有1就有了我直接把用户名和密码获取到，然后写了两个新密码、确认新密码
3.上图，为了让更方便了解

4.用户名、原密码我使用了不让用户点击(既然用户想改，那就不用他点击)：

android:clickable="true"
android:focusable="false"

5.实现代码：

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="10.0dip"
    android:layout_marginRight="10.0dip"
    android:layout_marginTop="20.0dip"
    android:background="@drawable/shape_bg"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="50.0dip"
        android:gravity="center_vertical"
        android:orientation="horizontal" >

        <TextView
            android:layout_width="1px"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="right"
            android:paddingLeft="15.0dip"
            android:text="账   号:"
            android:textColor="@android:color/black"
            android:textSize="18.0sp" />

        <EditText
            android:clickable="true"
            android:focusable="false"
            android:id="@+id/number"
            android:layout_width="1px"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10.0dip"
            android:layout_marginRight="15.0dip"
            android:layout_weight="2"
            android:background="@android:color/white"
            android:hint="请输入账号"
            android:inputType="textEmailAddress"
            android:maxLength="20"
            android:paddingLeft="10.0dip"
            android:textColor="#ff545454"
            android:textSize="16.0sp" />
    </LinearLayout>

    <View
        android:layout_width="fill_parent"
        android:layout_height="1.0px"
        android:background="@drawable/shape_line" />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="50.0dip"
        android:gravity="center_vertical"
        android:orientation="horizontal" >

        <TextView
            android:layout_width="1px"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="right"
            android:paddingLeft="15.0dip"
            android:text="原密码:"
            android:textColor="@android:color/black"
            android:textSize="18.0sp" />

        <EditText
            android:clickable="true"
            android:focusable="false"
            android:id="@+id/pwd"
            android:layout_width="1px"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10.0dip"
            android:layout_marginRight="15.0dip"
            android:layout_weight="2"
            android:background="@android:color/white"
            android:hint="请输入原密码"
            android:maxLength="20"
            android:inputType="textPassword"
            android:paddingLeft="10.0dip"
            android:textColor="#ff545454"
            android:textSize="16.0sp" />
    </LinearLayout>

    <View
        android:layout_width="fill_parent"
        android:layout_height="1.0px"
        android:background="@drawable/shape_line" />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="50.0dip"
        android:gravity="center_vertical"
        android:orientation="horizontal" >

        <TextView
            android:layout_width="1px"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="right"
            android:paddingLeft="15.0dip"
            android:text="新密码:"
            android:textColor="@android:color/black"
            android:textSize="18.0sp" />

        <EditText
            android:id="@+id/newPwd"
            android:layout_width="1px"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10.0dip"
            android:layout_marginRight="15.0dip"
            android:layout_weight="2"
            android:background="@android:color/white"
            android:hint="请输入新密码"
            android:inputType="textPassword"
            android:maxLength="20"
            android:paddingLeft="10.0dip"
            android:textColor="#ff545454"
            android:textSize="16.0sp" />
    </LinearLayout>

    <View
        android:layout_width="fill_parent"
        android:layout_height="1.0px"
        android:background="@drawable/shape_line" />

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="50.0dip"
        android:gravity="center_vertical"
        android:orientation="horizontal" >

        <TextView
            android:layout_width="1px"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:gravity="right"
            android:paddingLeft="15.0dip"
            android:text="确认新密码:"
            android:textColor="@android:color/black"
            android:textSize="18.0sp" />

        <EditText
            android:id="@+id/remPwd"
            android:layout_width="1px"
            android:layout_height="wrap_content"
            android:layout_marginLeft="10.0dip"
            android:layout_marginRight="15.0dip"
            android:layout_weight="2"
            android:background="@android:color/white"
            android:hint="请确认新密码"
            android:inputType="textPassword"
            android:maxLength="20"
            android:paddingLeft="10.0dip"
            android:textColor="#ff545454"
            android:textSize="16.0sp" />
    </LinearLayout>
</LinearLayout>

<Button
    android:id="@+id/btnConfirm"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_marginLeft="20.0dip"
    android:layout_marginRight="20.0dip"
    android:layout_marginTop="20.0dip"
    android:background="@drawable/shape_radius_color_square"
    android:text="完 成"
    android:textColor="#ff000000"
    android:textSize="18.0sp" />

6.使用的是高相同、宽等分，Button给它添加了一个形状Shape

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <solid android:color="#FF3366"/>

    <corners android:radius="10dp"/>
    
</shape>
