paip.android环境搭建与开发事例
好长时间没有玩AndROID了。。以前常常做ANDROID的，今天决定在下载一个要做个时间设置器

1. 下载ECLIPSE+ADT+SDK
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..
2. 建立项目
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。。
3. 建立界面
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>
4. 查看启动界面
/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>
5. 建立按键点击事件
<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
6.调试
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。

就OK了。。
