1先建立一个activity_main.xml 。代码如下：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:orientation="vertical"
   android:background="@drawable/loginbg"
   android:paddingBottom="@dimen/activity_vertical_margin"
   android:paddingLeft="@dimen/activity_horizontal_margin"
   android:paddingRight="@dimen/activity_horizontal_margin"
   android:paddingTop="@dimen/activity_vertical_margin"
   tools:context=".MainActivity" >

<include layout="@layout/login_top"/>
<include layout="@layout/login_bottom"/>"

</LinearLayout>
2：在建立login_botton.xml , login_top.xml

代码如下：

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

    <TextView
        android:id="@+id/tvRegist"
        android:layout_width="wrap_content"
       android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="21dp"
        android:layout_marginTop="18dp"
        android:text="@string/tvRegister"
        android:autoLink="all"
        android:textColorLink="#FF0066CC" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
       android:layout_marginBottom="24dp"
        android:src="@drawable/panda" />

    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="28dp"
        android:src="@drawable/icon" />

</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/btnbg_roundcorner"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin" >

    <TextView

        android:layout_alignParentTop="true"
        android:text="@string/tvName"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <EditText
        android:id="@+id/etUsername"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/tvUsername"
        android:layout_below="@+id/tvUsername"
        android:background="@android:drawable/edit_text"
        android:ems="10" >

        <requestFocus />
    </EditText>

    <TextView
        android:id="@+id/tvPassword"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/etUsername"
        android:layout_below="@+id/etUsername"
        android:text="@string/tvPassword"
        android:textAppearance="?android:attr/textAppearanceMedium" />

    <EditText
        android:id="@+id/etPassword"
       android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/tvPassword"
        android:layout_below="@+id/tvPassword"
        android:layout_marginTop="16dp"
        android:background="@android:drawable/edit_text"
        android:ems="10"
        android:inputType="textPassword" />

    <Button
        android:id="@+id/btnLogin"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignRight="@+id/etPassword"
        android:layout_below="@+id/etPassword"
       android:layout_marginTop="20dp"
        android:background="#FF72CAE1"
        android:text="@string/btnLogin" />

    <CheckBox
        android:id="@+id/cbRememberPass"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
