Bundle bundle = this.getIntent().getExtras(); if(bundle !=null){

?Fragment、getArguments()

傳

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);

傳遞

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

接收

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

發起跳轉

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

public static final int REQUEST_CODE_CAR = 10002; startActivityForResult(MoreCarActivity.newIntent(this, true), REQUEST_CODE_CAR);

回調接收數據

@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;}} }

?返回數據

public static final String RESULT_BEAN = "result_bean"; Intent mIntent = new Intent(); mIntent.putExtra(RESULT_BEAN, (Serializable)selectdatalist); setResult(RESULT_OK, mIntent); finish();

//回到首頁 Intent mainIntent = MainActivity.getIntent(BatteryOrderActivity.this, 4); //打開訂單列表 Intent orderListIntent = new Intent(BatteryOrderActivity.this, MyBatteryOrderActivity.class); //打開訂單明細 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;} }

?發送。。REQUEST_QR_CODE 是請求碼

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==請求碼==="+requestCode+".。。。返回碼..."+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是返回碼

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