在 SecondScreen() 中，我只是将 String 变量传递回 MainContainer()，我想在 Text('Don\'t result') 小部件中显示此变量，但我不知道该怎么做
主要活动：
问题是在三个fragment中的几次transition之后（大约3个transition之后），fragment的view一直在后台，也就是没有变化，应用没有crash，内存没有增长（used,check in the工作室）。

IntBuffer ib = fc.map(
FileChannel.MapMode.READ_WRITE, 0, fc.size()).asIntBuffer();
for (int i = 0; i < string.toCharArray().length; i++) {
ib.put(string.toCharArray()[i]);

有一种从 json 接收数据并创建的方法Observable<>，我需要从中获取数据并将其保存到List<>：
@NonNull
public Observable<List<BaseProducts>> getProducts(){
return bankApi.getProductsObservable()
//здесь получаю result
.map(productResponseApiResponse -> productResponseApiResponse.getResult())
//здесь конвертирую result в готовые типы (DTO)
.map(response -> converter.convert(response))
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread());
}
接下来，我需要过滤数据并将其传递给 List<>
@NonNull
private Observable<List<BaseProducts>> getActive(){
return getProducts()
.flatMap(Observable::fromIterable)
.filter(products -> !products.getStatus().equals(ACTIVE_PRODUCTS))
.toList()
.toObservable();
}
有一个过滤，我现在如何将过滤后的流保存在 List<> 中？
例如，如果您保存到List<>
@NonNull
public List<BaseProducts> getActiveProducts(){
List<BaseProducts> activeProducts = new ArrayList<>();
getProducts()
.subscribe(products -> activeProducts.addAll(products));
return activeProducts;
}
但是通过debugger显示activeProducts = null当它products存储数据时
@Inject
public ProductsItemBuilderImpl(@NonNull ProductsRepository repository) {
this.baseProducts = repository.getActiveProducts();
}
@NonNull
@Override
public List<BaseProductsItem> build() {
buildDeposits(baseProducts);
buildCredits(baseProducts);
buildDebitCards(baseProducts);
buildCreditCards(baseProducts);
return baseProductsItems;
}
在这里，我将其称为 List

有一个线程在其中填充和生成列表。需要将其转移到适配器中的主线程，如何做到这一点？
private class LooperThread extends Thread implements Handler.Callback{
Handler handler;
@Override
public void run() {
Looper.prepare();
handler = new Handler(this);
Looper.loop();
}
@Override
public boolean handleMessage(Message message) {
if(message.what == 0){
DepositGeneration generation = new DepositGeneration();
DepositOperations operations = new DepositOperations(generation.setList());
List<DepositItem> list = operations.sortedList();
List<BaseProduct> products = DepositFormatter.setProducts(list);
}
return true;
}
public Handler getHandler() {
return handler;
}
}
在这个类中，生成了一个List，应该输出到Log，但是这并没有发生，虽然创建了流
private class LooperThread extends Thread implements Handler.Callback{
Handler handler;
@Override
public void run() {
Looper.prepare();
handler = new Handler(this);
Looper.loop();
}
@Override
public boolean handleMessage(Message message) {
if(message.what == 0){
DepositGeneration generation = new DepositGeneration();
DepositOperations operations = new DepositOperations(generation.setList());
List<DepositItem> list = operations.sortedList();
for (int i = 0; i < list.size(); i++) {
Log.d("TAG", list.get(i).getName() +
" " + new SimpleDateFormat("dd.MM.yyyy").format(list.get(i).getOpenedDate()) +
" " + new DecimalFormat("#0.00").format(list.get(i).getAmount()));
}
}
return true;
}
public Handler getHandler() {
return handler;
}
}
而他的呼唤
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
looperThread = new LooperThread();
looperThread.start();
}
最后我破坏了溪流
@Override
public void onDestroy() {
if(looperThread.getHandler() != null){
Log.d("TAG", "DESTROY");
looperThread.getHandler().getLooper().quit();
}
super.onDestroy();
}
已销毁出口的日志中的消息
更改呼叫和传递消息但未执行
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
looperThread = new LooperThread();
if (looperThread.getHandler() != null){
Message message = looperThread.getHandler().obtainMessage(0);
message.sendToTarget();
}
looperThread.start();
}
