02 - Android入门程序 电话与短信

电话程序：

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

public class MainActivity extends Activity {/** Called when the activity is first created. */@Overridepublic 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 {@Overridepublic 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. */@Overridepublic 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 {@Overridepublic 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(); }}}

<uses-permission android:name="android.permission.SEND_SMS"/>
