android中实现发短信功能

发送短信和拨打电话牵涉到用户的隐私的时候需权限的

在AndroidManifest.xml中添加权限（AndroidManifest.xml----Permissions---add）

android.permission.SEND_SMS

public class SmsActivity extends Activity implements OnClickListener {

    /** Called when the activity is first created. */
private EditText numberText;
private EditText contentText;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button send=(Button) this.findViewById(R.id.send_button);
        numberText = (EditText) this.findViewById(R.id.number);

        contentText = (EditText) this.findViewById(R.id.content);

send.setOnClickListener(this);

}

private void send_phone() {
String number= numberText.getText().toString();
String content=contentText.getText().toString();
//String regex ="[\\d]{6,}?";

//boolean flag = number.matches(regex);
if(TextUtils.isEmpty(number) ||TextUtils.isEmpty(content))
{
if(TextUtils.isEmpty(number))
Toast.makeText(this,R.string.errornumber,Toast.LENGTH_LONG).show();
else
Toast.makeText(this, R.string.errorcontent, Toast.LENGTH_SHORT).show();
return;
}
else
{
SmsManager manager =SmsManager.getDefault();///取得系统默认的短信管理
ArrayList<String> texts= manager.divideMessage(content);//对短信进行拆分发送
/*Iterator<String> it = texts.iterator();
while(it.hasNext()){
String text=it.next();
manager.sendDataMessage(number, null, text, data, sentIntent, deliveryIntent)
//发送短信方法(参数依次是要发送的号码，中心号码null代表默认,短信内容，)
}传统迭代器*/
for(String text:texts)
{
manager.sendTextMessage(number, null, text
,null, null);
//发送短信方法(参数依次是要发送的号码，中心号码null代表默认,短信内容,发送状态,对方是否收到短信，)
}
Toast.makeText(SmsActivity.this,R.string.success,Toast.LENGTH_LONG).show();
}
}

public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.send_button:
send_phone();
break;
}
}

}
