Hi guys I badly need your help. I am making an automatic scrollview with timer but I got an error. Please help me out. Here is my code:
public void scrollRight(final ScrollView h){
new CountDownTimer(10000, 25) {
public void onTick(long millisUntilFinished) {
h.scrollTo((int) (2000 - millisUntilFinished), 0);
}
#Override
public void onFinish() {
// TODO Auto-generated method stub
}
}.start();}
Error: The method scrollTo is undefined for the type scrollview android
Your exact code does not give me any problems. Perhaps you're importing a different ScrollView?

I use react-native to develop an app, and I need to connect to braintree (paypal value). The official provides 3 kinds of sdk, js, android, and ios. I try to connect to the native android library, but it doesn't seem to have any effect.After calling the native method in ReactNative, only "react-native-test" is output (No error is reported, and there is no change on the interface. It seems that it should jump to PayPal authorization to be normal). I'm not sure if it's my problem . I also tried to use js library in react-native, but after importing a certain method, my program doesn't start. Or can I only do it in webView? Has anyone connected with PayPal value? Can you give me some advice? Thanks.
Here is the documentation I refer to.
Below is my android codeļ¼
public class BraintreeValueModule extends ReactContextBaseJavaModule implements PayPalListener {
private static ReactApplicationContext reactContext;
private Callback successCallback;
private Callback errorCallback;
private BraintreeClient braintreeClient;
private PayPalClient payPalClient;
public BraintreeValueModule(ReactApplicationContext context) {
super(context);
reactContext = context;
}
#NonNull
#Override
public String getName() {
return "BraintreeValueModule";
}
#ReactMethod
public void test(){
System.out.println("react-native-test");
braintreeClient = new BraintreeClient(reactContext.getApplicationContext(), "sandbox_ykbznr4s_ctmssyj6wz2qcj2g");
FragmentActivity activity = (FragmentActivity) getCurrentActivity();
activity.runOnUiThread(new MyRunnable(activity,braintreeClient));
//The following writing method will report an error: Method addObserver must be called on the main thread
//if(activity != null){
// payPalClient = new PayPalClient(activity, braintreeClient);
// payPalClient.setListener(this);
//}
}
#Override
public void onPayPalSuccess(#NonNull PayPalAccountNonce payPalAccountNonce) {
successCallback.invoke(payPalAccountNonce.toString());
}
#Override
public void onPayPalFailure(#NonNull Exception error) {
if (error instanceof UserCanceledException) {
// user canceled
errorCallback.invoke("use canceled");
} else {
// handle error
errorCallback.invoke("error");
}
}
}
public class MyRunnable implements Runnable, PayPalListener {
private BraintreeClient braintreeClient;
private PayPalClient payPalClient;
private FragmentActivity activity;
MyRunnable(FragmentActivity activity,BraintreeClient braintreeClient){
this.activity = activity;
this.braintreeClient = braintreeClient;
}
#Override
public void run() {
if(activity != null){
payPalClient = new PayPalClient(activity, braintreeClient);
payPalClient.setListener(this);
}
}
#Override
public void onPayPalSuccess(#NonNull PayPalAccountNonce payPalAccountNonce) {
System.out.println(payPalAccountNonce.getString());
}
#Override
public void onPayPalFailure(#NonNull Exception error) {
if (error instanceof UserCanceledException) {
// user canceled
System.out.println("use canceled");
} else {
// handle error
System.out.println("error");
}
}
}
I believe you might have missed out the following few lines:
PayPalVaultRequest request = new PayPalVaultRequest();
request.setBillingAgreementDescription("Your agreement description");
payPalClient.tokenizePayPalAccount(getCurrentActivity(), request);
However, I believe it might still not work as I had similar problem when I was trying to integrate the drop-in.
I'm afraid that you'll need to initialise your clients (in your case, BraintreeClient and PaypalClient) in the onCreate method of your MainActivity.
And then try to call a reference to the client (either by SharedPreference or static variable) in your module to launch the drop in.
Pretty sure it's similar issue to your case.
This only applies to the v4 library.

In Vaadin Flow, there exists no Component that is essentially a Scrollable Layout.
In Vaadin 8, this was done by the Panel.
Is there a way to achieve a scrollable Component in Vaadin Flow?
Edit: I have now published an add-on here that provides the class VerticalScrollLayout, and also the class HorizontalScrollLayout. If there are suggestions for improvements, feel free to contact me or comment here.
Yes it is possible, although there is no existing Component that does it automatically.
The way to go is placing a VerticalLayout (for a vertical scroll bar) inside another component, and setting the display property of that VerticalLayout from flex to block. (credits to Diego Sanz Villafruela in the vaadin forum)
I have made my own VerticalScrollLayout class that does it all for you, so that using it in a view is as easy as using a simple VerticalLayout
public class VerticalScrollLayout extends VerticalLayout {
private VerticalLayout content;
public VerticalScrollLayout(){
preparePanel();
}
public VerticalScrollLayout(Component... children){
preparePanel();
this.add(children);
}
private void preparePanel() {
setWidth("100%");
setHeight("100%");
getStyle().set("overflow", "auto");
content = new VerticalLayout();
content.getStyle().set("display", "block");
content.setWidth("100%");
content.setPadding(false);
super.add(content);
}
public VerticalLayout getContent(){
return content;
}
#Override
public void add(Component... components){
content.add(components);
}
#Override
public void remove(Component... components){
content.remove(components);
}
#Override
public void removeAll(){
content.removeAll();
}
#Override
public void addComponentAsFirst(Component component) {
content.addComponentAtIndex(0, component);
}
}
There is now an official component for scrolling:

I have implemented glide very well but the problem is that it loads same image for different imageviews with different urls in recyclerview.
The main question is how can I load the required images and still keep local caching to save user data? Here is my code:
Glide.with(context).load(objects.get(position)).apply(new RequestOptions().fitCenter().error(R.drawable.logo).placeholder(R.drawable.logo).diskCacheStrategy(DiskCacheStrategy.ALL)).into(new SimpleTarget<Drawable>() {
#Override
public void onResourceReady(#NonNull Drawable resource, #Nullable Transition<? super Drawable> transition) {
imageView.setImageDrawable(resource);
progressBar.setVisibility(View.GONE);
}
});
Instead of doing something like this:
.into(new SimpleTarget<Drawable>() {
#Override
public void onResourceReady(#NonNull Drawable resource, #Nullable Transition<? super Drawable> transition) {
imageView.setImageDrawable(resource);
progressBar.setVisibility(View.GONE);
}
});
Just simply put into the into function your imageView. If you still want to be notified whenever loading has been done you can use listener function. Your code should look like this:
Glide
.with(context)
.load(objects.get(position))
.apply(new
RequestOptions()
.fitCenter()
.error(R.drawable.logo)
.placeholder(R.drawable.logo)
.diskCacheStrategy(DiskCacheStrategy.ALL)
)
.listener(new SimpleTarget<Drawable>() {
#Override
public void onResourceReady(#NonNull Drawable resource, #Nullable
Transition<? super Drawable> transition) {
progressBar.setVisibility(View.GONE);
}
})
.into(imageView);
Glide should handle the RecyclerView lifecycle by its own. The only thing that you need to do is to hide progress bar. You do not need to set the drawable into the ImageView by yourself.
UPDATE:
The mentioned approach is the best however it gives me some lint errors when using SimpleTarget<?>() inside .listener(), maybe be due to possible version difference and has forced me to use RequestListener<Drawable>() and it works:
Glide.with(holder.service_image.getContext()).load(imageArray.get(0)).apply(new RequestOptions().fitCenter().error(R.drawable.logo).placeholder(R.drawable.logo).diskCacheStrategy(DiskCacheStrategy.ALL)).listener(new RequestListener<Drawable>() {
#Override
public boolean onLoadFailed(#Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
return false;
}
#Override
public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
holder.progressBar.setVisibility(View.GONE);
return false;
}
}).into( holder.service_image);
I'm trying to stop Android Studio Preview (ie IntelliJ) from adding in a newline / carriage return after an anonymous inner class when it's defined as a method parameter. It changes this:
runOnUiThread(new Runnable() {
#Override
public void run() {
//Some code
}
});
to this:
runOnUiThread(new Runnable() {
#Override
public void run() {
//Some code
}
}
);
I've looked through the formatting settings, but can't seem to find the relevant setting.
Check out these options:

Iam developing a RCP application which consists of views and editors. I can change the values and edit the values of some parameters in editor. When a value has been changed, i need to make the editor dirty as well as would also like to enable the save button. Till now, i have not implemented my save button. Could anyone guide me how to make the save button enabled as well as how can i make an editor dirty when some modifications happen in editor.
Thanks in advance. Any help will be greatly appreciated.

Here is an overview of the Form editor logic, hop it will help you.
public class TestEditor extends FormEditor {
#Override
protected void addPages() {
// this method is called when the editor is being created
// to add the necessary pages
// page classes should be like following
// class TestEditorPage extends FormPage
try {
TestEditorPage pageTest = new TestEditorPage(this);
addPage(pageTest);
} catch (PartInitException e) {
}
}
#Override
public void doSave(IProgressMonitor monitor) {
// this method will be called on save action
// (or Ctrl + s shortcut)
}
#Override
public void doSaveAs() {
// this method will be called on save-as
//call (or Ctrl + Shift + s shortcut)
}
#Override
public boolean isSaveAsAllowed() {
// put here the call to the logic that
// check if the save is allowed
return true;
}
#Override
public boolean isDirty() {
// Here the call for the logic that
// defines if the editor is dirty or not
return true;
}
}
