以前都是一个个单独下载，现在都可以集成在一起了。。

adt-bundle-windows-x86-20130729.ZIP  （400M）

打开一看，晕，连C++都有了。。全面..

NEW >ANDROID APPLICATION..

MINI S DK：默认2.2,,比较合理不用改

Target sdk:指明最高SDK版本。。默认4.3,为了兼容性，也改成2.2.

Complile withd: 默认4.3,无法改改。还好，这个不影响。最后生成的APK可以在2.2下运行。。

拖拉个文本框，拖拉个按钮上去如下图

/atiapp2/res/layout/activity_main_activity1.xml  就是界面文件

<RelativeLayout 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: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=".MainActivity1" >

<TextView

android:id="@+id/textView1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:text="@string/hello_world" />

<Button

android:id="@+id/button1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignLeft="@+id/textView1"

android:layout_below="@+id/textView1"

android:layout_marginLeft="30dp"

android:layout_marginTop="104dp"

android:text="Button" />

</RelativeLayout>

/atiapp2/AndroidManifest.xml

要死有多个界面，可以指定启动界面

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.example.atiapp2"

android:versionCode="1"

android:versionName="1.0" >

<uses-sdk

android:minSdkVersion="8"

android:targetSdkVersion="8" />

<application

android:allowBackup="true"

android:icon="@drawable/ic_launcher"

android:label="@string/app_name"

android:theme="@style/AppTheme" >

<activity

android:name="com.example.atiapp2.MainActivity1"

android:label="@string/app_name" >

<intent-filter>

<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />

</intent-filter>

</activity>

</application>

</manifest>

<Button

android:id="@+id/button25"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_alignLeft="@+id/editText1"

android:layout_below="@+id/editText1"

android:layout_marginTop="28dp"

android:text="Button"

android:onClick="button1click" />

-----------MainActivity.java-------

publicvoid button1click(View view)

{

EditText  edt=(EditText)findViewById(R.id.editText1);

String str="my name is attilax";

edt.setText(str);

}

其中，R.java是系统自动生成。。所有的多个界面控件ID都累积在那里

调试前要建立个AVD虚拟设备..

再开始RUN AS>ANDROID APPLICATION

可以在CONSOLE下看到当前进展。。。模拟器启动比较慢，耐心等待。模拟器启动后不用关。。以后再次调试就很快。
