在子线程中发送短信,静态注册SentMsgReceiver。
1. 应该在子线程中执行发送短信的操作。
如果没有在子线程中发送短信会出现错误:点击发送短信之后,立即跳转到其他界面,那么这次发送短信可能就会失败!
请注意往子线程方法中传入外部的实参必须由final修饰。
private void performSendMessage(final String content) {
if(content.length()==0) {
Toast.makeText(mContext, "can't send a blank msg.", Toast.LENGTH_SHORT).show();
} else {
mEditMsg.setText("");
final String[] numbers = mNumber.split(",");
final Uri uri = Telephony.Sms.Outbox.addMessage(getContentResolver(), "13146491338", content,
null, System.currentTimeMillis(), false, mThreadId);
onOutboxAddMessage(uri);
mHandler.post(new Runnable() {
@Override
public void run() {
sendMessage(numbers[0], content, uri);
}
});
}
}
2. 应该将SentMsgReceiver静态注册,而不是在短信列表界面中动态注册。
如果在短信列表中动态注册,点击发送短信之后,立即跳转到其他界面,那么会执行onDestroy()方法,调用unRegisterReceiver()注销SentMsgReceiver。
在com.txrj.sms.receiver包中新建SentMsgReceiver类(在SentMsgReceiver.java文件实现)
public class SentMsgReceiver extends BroadcastReceiver {
Context mContext;
@Override
public void onReceive(Context context, Intent intent) {
mContext = context;
Uri uri = intent.getParcelableExtra(TxrjConstant.EXTRA_SENT_URI);
int resultCode = getResultCode();
if(resultCode == Activity.RESULT_OK) {
Toast.makeText(context, "send message success.", Toast.LENGTH_SHORT).show();
updateMsgType(uri, Sms.MESSAGE_TYPE_SENT);
} else if(resultCode == SmsManager.RESULT_ERROR_GENERIC_FAILURE) {
Toast.makeText(context, "Generic failure.", Toast.LENGTH_SHORT).show();
updateMsgType(uri, Sms.MESSAGE_TYPE_FAILED);
} else if(resultCode == SmsManager.RESULT_ERROR_NO_SERVICE) {
Toast.makeText(context, "service is currently unavailable.", Toast.LENGTH_SHORT).show();
updateMsgType(uri, Sms.MESSAGE_TYPE_FAILED);
} else if(resultCode == SmsManager.RESULT_ERROR_NULL_PDU) {
Toast.makeText(context, "no pdu provided.", Toast.LENGTH_SHORT).show();
updateMsgType(uri, Sms.MESSAGE_TYPE_FAILED);
} else if(resultCode == SmsManager.RESULT_ERROR_RADIO_OFF) {
Toast.makeText(context, "radio was explicitly turned off.", Toast.LENGTH_SHORT).show();
updateMsgType(uri, Sms.MESSAGE_TYPE_FAILED);
}
}
private void updateMsgType(Uri uri, int type) {
ContentValues values = new ContentValues();
values.put(Sms.TYPE, type);
mContext.getContentResolver().update(uri, values, null, null);
}
}
