Intent 传递数据为空原因

startActivityForResult(Intent intent, Int requestCode)
onActivityResult(int requestCode, int resultCode, Intent intent)

setResut(int resultCode, Intent intent)

注意要返回的是当前的界面下一个界面的数据,

注意比如在忘记密码的操作时,往往会有有好几个界面,这里要把数据连续传下去,否则会报错

A - -- > B ---- C

C -----A    这时就为空了(要把数据传到B-->A)

 intent bundle 传输数据

Intent intent = new Intent();
Bundle bundle = new Bundle();
bundle.putString(Config.MODEL_ID, modelId);
bundle.putString(Config.QINIU_KEY, picKey);
intent.putExtras(bundle);

或是

Bundle bundle = new Bundle();    
bundle.putString("phoneNO", "12345");    
SendSMSActivity.this.setResult(RESULT_CANCELED,SendSMSActivity.this.getIntent().putExtras(bundle));    
SendSMSActivity.this.finish();    

接收数据

Bundle bundle = getIntent().getExtras();
bundle.getInt(Config.DESIGN_TYPE, 1);
