Android HelloWord編寫方式介紹

相信學過編程的人員都對各種語言的helloWord程序的編寫方式記憶猶新吧。在這裡我們就為大家詳細介紹一下有關android HelloWord的編寫方式，方便大家對這一操作系統編寫方式的理解。

先說說整個程序要做哪些內容吧，簡單helloWord 通過一個按鈕點擊在另一個acitvity出現文本Hello xiaoshengDAI

說下android HelloWord做的步驟吧：

1.首先新建項目，我這邊主要是測試Layout所以項目名就叫這個了。

2.我們要顯示一個按鈕，難後點擊這個按鈕就轉到其他activity顯示Hello xiaoshengDAI，新建類Layout主要來顯示第一個activity即button，

1).在main.XML文件中進行配置

Java代碼

< ?XML version="1.0" encoding="utf-8"?>   
< LinearLayout XMLns:android=
"http://schemas.android.com/apk/res/android"   
android:orIEntation="vertical"   
android:layout_width="fill_parent"   
android:layout_height="fill_parent">   
< Button android:id="@+id/button1"   
android:layout_width="wrap_content"   
android:layout_height="wrap_content"   
android:text="來點我吧"/>   
< /LinearLayout>   
< ?XML version="1.0" encoding="utf-8"?> 
< LinearLayout XMLns:android=
"http://schemas.android.com/apk/res/android" 
android:orIEntation="vertical" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent">   
< Button android:id="@+id/button1"   
android:layout_width="wrap_content"   
android:layout_height="wrap_content"   
android:text="來點我吧"/>   
< /LinearLayout>  

2).設置監聽和跳轉actiovity

Java代碼

package com.layout;   
import android.app.Activity;   
import android.content.Intent;   
import android.os.Bundle;   
import android.view.VIEw;   
import android.view.VIEw.OnClickListener;   
import android.widget.Button;   
public class Layout extends Activity {   
/** Called when the activity is first created. */   
@Override   
public void onCreate(Bundle savedInstanceState) {   
OnClickListener listener1 = null;   
Button botton1 = null;   
listener1 = new OnClickListener(){   
public void onClick(VIEw v) {   
Intent intent0 = new Intent(Layout.this,
ActivityFrameLayout.class);   
setTitle("FrameLayout");   
startActivity(intent0);   
}   
};   
super.onCreate(savedInstanceState);   
setContentVIEw(R.layout.main);   
botton1 = (Button) findVIEwById(R.id.button1);   
botton1.setOnClickListener(listener1);   
}   
}   
package com.layout;  
import android.app.Activity;  
import android.content.Intent;  
import android.os.Bundle;  
import android.view.VIEw;  
import android.view.VIEw.OnClickListener;  
import android.widget.Button;  
public class Layout extends Activity {  
/** Called when the activity is first created. */  
@Override  
public void onCreate(Bundle savedInstanceState) {  
OnClickListener listener1 = null;  
Button botton1 = null;   
listener1 = new OnClickListener(){  
public void onClick(VIEw v) {   
Intent intent0 = new Intent(Layout.this,
ActivityFrameLayout.class);   
setTitle("FrameLayout");  
startActivity(intent0);  
}   
};   
super.onCreate(savedInstanceState);  
setContentVIEw(R.layout.main);  
botton1 = (Button) findVIEwById(R.id.button1);  
botton1.setOnClickListener(listener1);  
}  
} 

3.在android HelloWord編寫中，新建activityFrameLayout類和activityFrameLayout.XML文件

Java代碼

< ?XML version="1.0" encoding="utf-8"?>   
< LinearLayout XMLns:android=
"http://schemas.android.com/apk/res/android"   
android:orIEntation="vertical"   
android:layout_width="fill_parent"   
android:layout_height="fill_parent"   
>   
< TextVIEw   
android:layout_width="fill_parent"   
android:layout_height="wrap_content"   
android:text="Hello xiaoshengDAI"   
/>   
< /LinearLayout>   
< ?XML version="1.0" encoding="utf-8"?> 
< LinearLayout XMLns:android=
"http://schemas.android.com/apk/res/android" 
android:orIEntation="vertical" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
> 
< TextVIEw   
android:layout_width="fill_parent"   
android:layout_height="wrap_content"   
android:text="Hello xiaoshengDAI" 
/> 
< /LinearLayout>  

Java代碼

package com.layout;   
import android.app.Activity;   
import android.os.Bundle;   
public class ActivityFrameLayout extends Activity {   
@Override   
protected void onCreate(Bundle savedInstanceState) {   
super.onCreate(savedInstanceState);   
setTitle("哈哈");   
setContentVIEw(R.layout.activityframelayout);   
}   
}   
package com.layout;  
import android.app.Activity;  
import android.os.Bundle;  
public class ActivityFrameLayout extends Activity {  
@Override  
protected void onCreate(Bundle savedInstanceState) {  
super.onCreate(savedInstanceState);  
setTitle("哈哈");  
setContentVIEw(R.layout.activityframelayout);  
}  
} 

4.對androidManifest.XML進行配置，將新建Activity配置文件加進來

android HelloWord的Java代碼

< ?XML version="1.0" encoding="utf-8"?>   
< manifest XMLns:android=
"http://schemas.android.com/apk/res/android"   
package="com.layout"   
android:versionCode="1"   
android:versionName="1.0">   
< application android:icon="@drawable/icon" 
android:label="@string/app_name">   
< activity android:name=".Layout"   
android:label="@string/app_name">   
< intent-filter>   
< action android:name="android.intent.action.MAIN" />   
< category android:name=
"android.intent.category.LAUNCHER" />   
< /intent-filter>   
< /activity>   
< activity android:name=".ActivityFrameLayout" 
android:label="activityFrameLayout">   
< intent-filter>   
< action android:name="android.intent.action.MAIN" />   
< category android:name=
"android.intent.category.LAUNCHER" />   
< /intent-filter>   
< /activity>   
< /application>   
< uses-sdk android:minSdkVersion="3" />   
< /manifest>   
< ?XML version="1.0" encoding="utf-8"?> 
< manifest XMLns:android=
"http://schemas.android.com/apk/res/android" 
package="com.layout" 
android:versionCode="1" 
android:versionName="1.0"> 
< application android:icon="@drawable/icon" 
android:label="@string/app_name"> 
< activity android:name=".Layout" 
android:label="@string/app_name"> 
< intent-filter> 
< action android:name="android.intent.action.MAIN" /> 
< category android:name=
"android.intent.category.LAUNCHER" /> 
< /intent-filter> 
< /activity> 
< activity android:name=".ActivityFrameLayout" 
android:label="activityFrameLayout"> 
< intent-filter> 
< action android:name="android.intent.action.MAIN" /> 
< category android:name=
"android.intent.category.LAUNCHER" /> 
< /intent-filter> 
< /activity> 
< /application> 
< uses-sdk android:minSdkVersion="3" /> 
< /manifest>  

5.android HelloWord可以運行了，嘿嘿
