                    Toast.makeText(this, "親，短信內容太長啦！", Toast.LENGTH_SHORT).show();
                }else if(etMes==null&&msg.equals("")){
                    Toast.makeText(this, "親，輸入短信內容！", Toast.LENGTH_SHORT).show();
                }else{
                    etMes.setText("正在發送，，，");
                    //得到SmsManager對象，用於短信的發送
                    SmsManager manage=SmsManager.getDefault();

                    manage.sendTextMessage(pNum, null,msg, null, null);
                    etMes.setText("短信已發送！");
                }
            }
        }
    }
}
public class TestActivity extends Activity implements OnClickListener {
private EditText etNum;
private EditText etMes;
private Button btnCall;
private Button btnSend;
@Override
public void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.main);

}

public void onClick(View v) {
  String pNum = etNum.getText().toString();
  if(pNum.equals("")){
   Toast.makeText(this, "親，輸入有效的電話號碼！", Toast.LENGTH_SHORT).show();
  }else {
   //call
   if(v.equals(btnCall)){

             Intent intent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:"+pNum));
             //撥號

    }else if(etMes==null&&msg.equals("")){
     Toast.makeText(this, "親，輸入短信內容！", Toast.LENGTH_SHORT).show();
    }else{
     etMes.setText("正在發送，，，");
     //得到SmsManager對象，用於短信的發送
     SmsManager manage=SmsManager.getDefault();
     //發送短息
     manage.sendTextMessage(pNum, null,msg, null, null);
     etMes.setText("短信已發送！");
    }
   }
  }
}
}代碼隻有這麼點，很簡單，但這樣還不能打電話，發短信，需要取得打電話和發短信的權限，

在AndroidManifest.xml中添加權限：

[html] <uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.SEND_SMS"/>
<uses-permission android:name="android.permission.CALL_PHONE"/>
<uses-permission android:name="android.permission.SEND_SMS"/>
可以打開2個模擬器測試打電話和發短信，號碼就是模擬器的ID，如：5554，
