第一个程序：酷驴拨号器

首先建一个Android工程：phone

string.xml

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

< resources >

     < string   name = "hello" > Hello World, PhoneActivity! </ string >

     < string   name = "app_name" > 酷驴拨号器 </ string >

     < string   name = "mobile" > 请输入手机号 </ string >

     < string   name = "button" > 拨打此号码 </ string >

</ resources >

main.xml

<? 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 = "@string/mobile"

     />

< EditText   

     android:layout_width = "fill_parent"  

     android:layout_height = "wrap_content"  

     android:id = "@+id/mobile"

     />

< Button   

     android:layout_width = "wrap_content"  

     android:layout_height = "wrap_content"  

     android:text = "@string/button"

     android:id = "@+id/button"

     />

</ LinearLayout >

在drawable-hdpi中加入donkey.png，酷驴这张图片

PhoneActivity.Java

package cn.itcast.activity;

import android.app.Activity;

import android.content.Intent;

import android.net.Uri;

import android.os.Bundle;

import android.view.View;

public class PhoneActivity extends Activity {

private EditText mobileText;

@Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

        mobileText = (EditText)this.findViewById(R.id.mobile);

        

        Button button = (Button)this.findViewById(R.id.button);

        button.setOnClickListener(new View.OnClickListener() {

public void onClick(View v) {

String mobile = mobileText.getText().toString();

Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + mobile)); //动作

PhoneActivity.this.startActivity(intent);

}

});

    }

}
