对于短信发送器的实现，也是较简单的，总体来说只需要设置好布局文件和Activity类就可以了，但在此基础上，还需要进行对配置文件的设置，下面就让我们来进行演示：

在创建好项目之后，配置布局文件代码如下所示：

其中使用了组件AutoCompleteTextView组件，能够有提示的出现语句，在这儿我们用于提示电话号码，比如输入188时，再输入1时就会有提示188这个电话号码，在内容输入区，我们使用一个文本编辑框进行信息内容的传送，最后来一个发送按钮就可以完成布局了

<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="com.wusu.android_002_Message.MainActivity" >    <AutoCompleteTextView        android:id="@+id/editText_receive"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:layout_alignParentLeft="true"        android:layout_alignParentTop="true"        android:layout_marginTop="5dp"        android:inputType="number"        android:hint="@string/Input_number_of_receive"        android:ems="10" />        <EditText            android:id="@+id/editText_content"            android:layout_width="fill_parent"            android:layout_height="match_parent"            android:layout_above="@+id/button_send"            android:layout_alignRight="@+id/editText_receive"            android:layout_below="@id/editText_receive"            android:ems="10"            android:layout_marginTop="10dp"            android:hint="@string/Input_content"            android:gravity="top"            android:inputType="textMultiLine" >        <requestFocus />    </EditText>    <Button        android:id="@+id/button_send"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:layout_alignRight="@+id/editText_content"        android:layout_marginBottom="36dp"        android:layout_marginRight="14dp"        android:text="@string/send" /></RelativeLayout>

在写完布局之后，我们进行Activity类的编写，主要代码如下所示：

public class MainActivity extends Activity implements OnClickListener {private Button button_send;private TextView textView_content,textView_receive;  private AutoCompleteTextView autoCompleteTextView_number;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);button_send=(Button) findViewById(R.id.button_send);    button_send.setOnClickListener(this);textView_content=(TextView) findViewById(R.id.editText_content);textView_receive=(TextView) findViewById(R.id.editText_receive);   autoCompleteTextView_number=(AutoCompleteTextView) findViewById(R.id.editText_receive);       ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line,numbers);       autoCompleteTextView_number.setAdapter(adapter);}//显示要提示的电话号码 private String[] numbers={"1880","150","1008611","10086","151","1234567890","9876543210","725610987678","226610"}; @Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.main, menu);return true;}@Overridepublic boolean onOptionsItemSelected(MenuItem item) {// Handle action bar item clicks here. The action bar will// automatically handle clicks on the Home/Up button, so long// as you specify a parent activity in AndroidManifest.xml.int id = item.getItemId();if (id == R.id.action_settings) {finish();return true;}return super.onOptionsItemSelected(item);}@Overridepublic void onClick(View view) {switch (view.getId()) {case R.id.button_send:String content=textView_content.getText().toString();String number=textView_receive.getText().toString();if(TextUtils.isEmpty(number)){Toast.makeText(MainActivity.this,"请输入电话号码...", Toast.LENGTH_SHORT).show();  return;}else{SmsManager smsManager=SmsManager.getDefault();ArrayList<String> contents=smsManager.divideMessage(content);for(String str:contents){smsManager.sendTextMessage(number,null, str, null, null);    }Toast.makeText(this, "已发送", Toast.LENGTH_SHORT).show();}break;default:break;}}}

</pre><p></p><pre>

现在，在进行配置文件，只需在配置文件中添加即可

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

以上就是Android中短信息发送功能的实现
