本文介绍了一个简单的Android应用程序，该程序实现了电话拨打及短信发送功能。通过使用Intent进行电话号码的调用，并利用SmsManager实现短信的发送。

电话程序：

/phone/src/cn/itcast/phone/MainActivity.java

public class MainActivity extends Activity {
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		Button button = (Button) this.findViewById(R.id.button);
		button.setOnClickListener(new ButtonClickListener());
	}

	private final class ButtonClickListener implements View.OnClickListener {

		@Override
		public void onClick(View v) {
			EditText mobileText = (EditText) findViewById(R.id.mobile);
			String number = mobileText.getText().toString();
			Intent intent = new Intent();
			intent.setAction("android.intent.action.CALL");
			//intent.addCategory("android.intent.category.DEFAULT");
			intent.setData(Uri.parse("tel:"+number));
			startActivity(intent);
			
		}

	}
}

/phone/res/layout/main.xml 控制布局并定义元件

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

    <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" 
	    /><!-- 添加一个常量 -->
</LinearLayout>

/phone/res/values/strings.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello">Hello World, MainActivity!</string>
    <string name="app_name">电话拨号器</string>
    <string name="mobile">请输入手机号</string>
     <string name="button">请拨号</string> 
</resources>

/phone/AndroidManifest.xml

    <!-- 添加拨打电话权限 系统安装的时候就会提示 -->
	<uses-permission android:name="android.permission.CALL_PHONE"/>"

短信发送程序：

public class SmsActivity extends Activity {
	private EditText numberText;
	private EditText contentText;

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		numberText = (EditText) this.findViewById(R.id.number_text);
		contentText = (EditText) this.findViewById(R.id.content_text);
		Button sendButton = (Button) this.findViewById(R.id.send_button);
		sendButton.setOnClickListener(new ButtonClickListener());
	}

	private final class ButtonClickListener implements View.OnClickListener {
		@Override
		public void onClick(View v) {
			String number = numberText.getText().toString();
			String content = contentText.getText().toString();
			SmsManager manager = SmsManager.getDefault();
			ArrayList<String> texts = manager.divideMessage(content);
			// 过大则拆分
			for (String text : texts) {
				manager.sendTextMessage(number, null, text, null, null);
			}
			Toast.makeText(getApplicationContext(), R.string.send_sucuess, 3).show(); 
		}
	}
}
