自定义广播，需要清单文件写action
    

  1. public class SmsSendSuccessReceiver extends BroadcastReceiver{
    2. 

    3. 

  3. 	@Override
    4. 

  4. 	public void onReceive(Context context, Intent intent) {
    5. 

  5. 		Toast.makeText(context, "短信已经发送成功", 0).show();
    6. 

  6. 	}
    7. 

  7. }
    8.
清单文件：注意输入的模式就变了，发送按钮在输入法上面了
    

  1.    <activity
    2. 

  2.             android:name="com.itheima.smsmanager39.NewMessageUI"
    3. 

  3.             android:label="@string/app_name"

  4.             android:windowSoftInputMode="adjustResize">
