java - 你如何使用android sdk发送短信

Question

我正在尝试弄清楚如何从我的应用程序发送短信。我尝试了以下方法:

try { 
    String newNumber, newMessage;
    newNumber = number.getText().toString();
    newMessage = message.getText().toString();
    smsManager.getDefault();
    smsManager.sendTextMessage(newNumber, null, newMessage,null, null);

    } catch (InterruptedException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
     }  
    }
}
    };thread.start();

但是我得到了一只原木猫:

07-23 09:03:42.378: I/Process(14426): Sending signal. PID: 14426 SIG: 9 07-23 09:06:18.972: W/dalvikvm(14529): threadid=11: thread exiting with uncaught exception (group=0x40a381f8) 07-23 09:06:18.972: E/AndroidRuntime(14529): FATAL EXCEPTION: Thread-885 07-23 09:06:18.972: E/AndroidRuntime(14529): java.lang.NullPointerException 07-23 09:06:18.972: E/AndroidRuntime(14529): at com.johnnydicamillo.sms.SmsSpammerActivity$1.run(SmsSpammerActivity.java:48) 07-23 09:06:19.238: W/IInputConnectionWrapper(14529): showStatusIcon on inactive InputConnection 07-23 09:06:44.855: I/Process(14529): Sending signal.

Answer 1

看起来smsManager可能为空，getDefault()是一个静态方法，用于获取SmsManager的默认实例，它并不表明您正在设置任何内容。您可能希望该行类似于:

SmsManager smsManager = SmsManager.getDefault();
