Bundle bundle = this.getIntent().getExtras();

if(bundle !=null){

 Fragment、getArguments()

传

public static DriverHistoryFragment getInstance(String tag) {Bundle bundle = new Bundle();bundle.putString(TAG, tag);DriverHistoryFragment fragment = new DriverHistoryFragment();fragment.setArguments(bundle);return fragment;
}

DriverHistoryFragment.getInstance(HISTORY)

取

mEnterTag = getArguments().getString(TAG);

传递

Intent intent = new Intent(GoodsDetailActivity.this, BuyOrderActivity.class);
intent.putExtra("datas", (Serializable) orderList);
intent.putExtra("type", BuyOrderActivity.SINGLE);
startActivity(intent);

 

intent.putExtra("put_ser_test",dto );

接收

mto = (BindCheckDTO)getIntent().getSerializableExtra("put_ser_test");

private List<OrderCommodity> orderList;

orderList = (List<OrderCommodity>) getIntent().getSerializableExtra("datas");

Bundle bundle = new Bundle();
bundle.putParcelableArrayList("goodsBeans", goodsBeans);
bundle.putString("totalPrice", totalPrice);
bundle.putString("orderId", orderId);
intent.putExtras(bundle);
context.startActivity(intent);

goodsBeans = getIntent().getParcelableArrayListExtra("goodsBeans");

 startActivityForResult的使用

发起跳转

List<CarBean.DataBean.ListBean> selectdatalist  = new ArrayList<>();

public static final int REQUEST_CODE_CAR = 10002;

startActivityForResult(MoreCarActivity.newIntent(this, true), REQUEST_CODE_CAR);

回调接收数据

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);if (resultCode != RESULT_OK) {return;}if (data != null) {switch (requestCode) {case REQUEST_CODE_CAR:selectdatalist = (List<CarBean.DataBean.ListBean>) data.getSerializableExtra(CarActivity.RESULT_BEAN);setCarInfo();break;}}
}

 返回数据

public static final String RESULT_BEAN = "result_bean";

Intent mIntent = new Intent();
mIntent.putExtra(RESULT_BEAN, (Serializable)selectdatalist);
setResult(RESULT_OK, mIntent);
finish();

//回到首页
Intent mainIntent = MainActivity.getIntent(BatteryOrderActivity.this, 4);
//打开订单列表
Intent orderListIntent = new Intent(BatteryOrderActivity.this, MyBatteryOrderActivity.class);
//打开订单明细
Intent orderDetailIntent = BatteryOrderDetailsActivity.getIntent(BatteryOrderActivity.this, orderId);
startActivities(new Intent[]{mainIntent, orderListIntent, orderDetailIntent});

回去

 setResult(RESULT_OK);

接收

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);if (resultCode != RESULT_OK) {return;}switch (requestCode) {case REQUEST_CODE_RELEASE:mViewpager.setCurrentItem(0);mNewOrdersFragment.mRefreshLayout.startRefresh();break;}
}

 发送。。REQUEST_QR_CODE 是请求码

Intent i = new Intent(MainActivity.this, SimpleCaptureActivity.class);
MainActivity.this.startActivityForResult(i, REQUEST_QR_CODE);

    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {super.onActivityResult(requestCode, resultCode, data);LgqLogPlus.d("cccccc==请求码==="+requestCode+".。。。返回码..."+resultCode);if (resultCode == 3&& requestCode == REQUEST_QR_CODE&& data != null) {String result = data.getStringExtra("function_test");Toast.makeText(MainActivity.this, result, Toast.LENGTH_SHORT).show();}
}

返回   3是返回码

Intent intent = new Intent();
intent.putExtra("function_test",resultString);
setResult(3, intent);
finish();
