I use the library: https://pub.dev/packages/share
image1
image2
And when pressing quickly and continuously on a button, many bottom sheets are displayed. How to only have 1 bottom sheet visible?
Question: What you can do to avoid this?
Answer: Declare a bool right here =>
class YourAppState extends State<YourApp> {
bool _isClicked = false;
and then use it in your method _showShare()
void _showShare() async {
if(!_isCLicked)
{
await Share.share("https://xxxx.com");
_isCLicked =true;
}
}
and when you want to use that share feature again revert its value to false.
You can use a flag for your problem when ever user select sharing icon, your flag will be false and when sharing modal will open completely your flag will be true again.
finally use your flag for handling that is user selecting the sharing icon or not

I got an Checkbox and I want that when someone click the checkbox in a other Activity an Text appeared...
I know how to make Listeners with Checkboxes and how to make a Text appear, but my App crashes when I click the CheckBox, so I think I need to make an thing that transfer the information that the CheckBox has been clicked to the other Activity... but How?
I tried to make make something with thes putExtras and getExtras, but I didnt found anything that helped!
Code
public void doSomethingWhenCheckBoxClicked(View v) {
boolean checked = ((CheckBox) v).isChecked();
switch (v.getId()) {
case R.id.checkBox1:
if (checked) {
Intent myIntent = new Intent(MainActivity2.this, MainActivity.class);
myIntent.putExtra("checked", true);
}
}
}
I'm using UploadItem, RadioGroupItem and some other widgets. RadioButton is having onChangeHandler which will decide what all other components need to be displayed. I've uploaded some file using UploadItem. Then I changed the radio button selection. On changing the radio button, required widgets are getting displayed properly but whatever file I'd selected using UploadItem is going away. Fresh UploadItem widget is getting displayed. In other words page is getting refreshed.
My requirement is whenever I change radio button option, required widget should displayed along with that whatever file I had selected using UploadItem should remain same.
My Code is something like this:
UploadItem upload = new UploadItem();
RadioGroupItem radioGroup = new RadioGroupItem();
HashMap map = new HashMap();
map.put("option1","option1");
map.put("option2","option2");
radioGroup.setValueMap(map);
TextItem textbox = new TextItem();
radioGroup.addChangeHandler(new ChangeHandler(){
public void onChanged(ChangedEvent event) {
String radioValue =((String)event.getValue());
if(radioValue.equalsIgnoreCase("option2")){
textbox.show();
}else{
textbox.hide();
}
}
});
Add all created widgets to DynamicForm object using dynamicForm.setFields(all created widgets)
Changing the radio button should hide and show the textBox. But while doing that page is getting refreshed and whatever file we had selected using UploadItem is lost.
As per the documentation for hide() and show() of FormItem class, invocation of any of these methods, will cause the DynamicForm to be redrawn.
So it may cause the problem you're getting.
To overcome this issue, I would suggest you to put UploadItem in a separate DynamicForm.
fire an event on radio Selection change as
radioButton.addListener(Events.Change, new Listener<BaseEvent>() {
#Override
public void handleEvent(BaseEvent be) {
if(radioButton.getValue()){
//fire an event here for ur widget
}
}
});
I don't use tab panel just tab bar, and have to prevent changing tab by some criteria.
In ExtJS docs I found change event for Ext.tab.Bar, but it fires when tab is already changed. So preventDefault() and return false are not working in this case.
Second I tried is set Ext.tab.Tab.handler property when tabs were initialized, but it fires when tab button is already clicked. So preventDefault() and return false don't work too.
Can ony body help with this? How can I prevent changing tabs using only Ext.tab.Tab and Ext.tab.Bar?
Thx.
I think you can use the 'beforetabchange' event on the tab panel itself.
From sencha docs: http://docs.sencha.com/ext-js/4-0/#!/api/Ext.tab.Panel-event-beforetabchange .
Return false in any listener to cancel the tabchange.
Edit
Maybe you could then extend the Ext.tab.Bar component and register the beforechange event by modifying the setActiveTab method, I think it's a pretty easy modification
setActiveTab: function(tab) {
//test the beforechange return
if (tab.disabled && me.fireEvent('beforechange', tab) === false) {
return;
}
var me = this;
if (me.activeTab) {
me.previousTab = me.activeTab;
me.activeTab.deactivate();
}
tab.activate();
if (me.rendered) {
me.layout.layout();
tab.el && tab.el.scrollIntoView(me.layout.getRenderTarget());
}
me.activeTab = tab;
me.fireEvent('change', me, tab, tab.card);
}
Add a controller action "beforeshow" on the tab panel container and disable the listeners. Allows the tabs to behave normally without clickability.
component.down("#tabPanel").tabBar.clearListeners();
I want to if it is possible to disable the auto-close MenuBar when I click on a MenuItem?
I have several MenuItem that are like checkboxes, so I can check more than one MenuItem and don't want my menu close everytime I checked one.
Thanks.
I was facing same problem and I will share with you my solution:
1) Create new class MyMenuItemWithCheckBox that extends the MenuItem.
In the constructor set element ID to (forexample) menuItemWIthCheckBox + Unique text.
this.getElement().setId("menuItemWithCheckBox_" + menuItemLabel);
2) Create new class MyMenuBar that extends the MenuBar.
Override the onBrowserEvent method by following:
Override
public void onBrowserEvent(Event event) {
if (DOM.eventGetType(event) == Event.ONCLICK && getSelectedItem().getElement().getId().contains("CheckBox")) {
Scheduler.get().scheduleFinally(new Scheduler.ScheduledCommand() {
#Override
public void execute() {
getSelectedItem().getScheduledCommand().execute();
}
});
event.stopPropagation();
} else {
super.onBrowserEvent(event);
}
}
Now scheduled command of MenuItem is always called, but in the case of your
menu checkBox item there is no close of a menubar.
I hope this help you, I spend more than day to create this solution. :-)
First, directly it's not possible because the popup-panel which displays the submenu is private in the MenuBar class.
Buuut, there is a way to do so ...
Simpley fetch the current MenuBar.java code out of googles code repository and include it in your eclipse gwt-project.
You don't have to change anything e.g. package deklaration or something. Just put your source in your project and it will simply replace the original MenuBar-class from the gwt-sdk during compilation (works also with hosted development mode).
Then you can simply set the property autoHide of the popup-Panel to false and the popup shouldn't disappear after clicking.
You can set hideOnClick to false on the menuItems
See here.
system.logElementTree();
var target = UIATarget.localTarget();
target.onAlert = function onAlert(alert) {
UIALogger.logDebug("There was an alert!");
target.onAlert.buttons()["No"].tap({x:164,y:278});
return false;
even though no option is clicked systen not performing any action
Can anyone please help me ...
Instead of BamboOS suggestion which loops through various positions, you can try this inside your onAlert function:
alert.tapWithOptions({tapOffset:{x:0.5, y:0.6}});
This tap targets the middle of the UIAAlert (x:0.5) and 60% from top to bottom (y:0.6). This works when there is only one button. You have multiple buttons, then you have to changed the value of x. This works for me.
I just published a blog post regarding UI Automation and dealing with alerts:
http://www.conduce.net/Blog.aspx?f=Automated-Test-of-iPad-Apps
Basically following alert handler worked for me:
UIATarget.onAlert = function onAlert(alert){
var name = alert.name();
UIALogger.logMessage("alert "+name+" encountered");
if(name == "errorAlert"){
var positionX = 500;
for(var positionY=300; positionY<600;positionY+=10){
target.tap({x:positionX,y:positionY});
}
return true;
}
return false;
}
I would either use the "cancelButton" or "defaultButton" methods when handling alerts.
