android短信发送器源码如下：

程序主文件 MainActiviy.java

package com.example.sms;

import java.util.ArrayList;

import android.os.Bundle; import android.app.Activity; import android.telephony.SmsManager; import android.view.Menu; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.Toast;

public class MainActivity extends Activity { private EditText numberText; private EditText contentText; private Button button;

@Overridepublic void onCreate(Bundle savedInstanceState) {	super.onCreate(savedInstanceState);	setContentView(R.layout.activity_main);	numberText = (EditText) this.findViewById(R.id.number);	contentText = (EditText) this.findViewById(R.id.content);	button = (Button) this.findViewById(R.id.button);	button.setOnClickListener(new ButtonClickListener());}private final class ButtonClickListener implements View.OnClickListener {	public void onClick(View arg0) {		String number = numberText.getText().toString();		String content = contentText.getText().toString();		SmsManager manager = SmsManager.getDefault();		ArrayList
    
      texts = manager.divideMessage(content);		for (String text : texts) {			manager.sendTextMessage(number, null, text, null, null);		}		Toast.makeText(MainActivity.this, "短信已经发送成功", Toast.LENGTH_LONG).show();	}}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {	getMenuInflater().inflate(R.menu.activity_main, menu);	return true;}
    

}

此文件是布局管理用与下面文件配套使用string.xml <resources>
