In ConstraintLayout , there is some codes written below:
protected boolean isRtl() {
if (android.os.Build.VERSION.SDK_INT >= 17) {
boolean isRtlSupported = (this.getContext().getApplicationInfo().flags & 4194304) != 0;
return isRtlSupported && 1 == this.getLayoutDirection();
} else {
return false;
}
}
And I copy this to my custom layout, Android Studio cannot read the "1" in && 1 .
Why a boolean can && a int ?
Sorry, it should be read as follows
return isRtlSupported && (1 == this.getLayoutDirection());
Here 1 is replaced by View.LAYOUT_DIRECTION_RTL works fine.
i.e.
return isRtlSupported && (View.LAYOUT_DIRECTION_RTL == this.getLayoutDirection());
where
public static final int LAYOUT_DIRECTION_RTL = LayoutDirection.RTL;
in View.java
and
public static final int RTL = 1;
in LayoutDirection.java

I am trying to make it so each finger on the screen has a different color as it paints its path. I am using pointers to create the path and toyed with assigning the pointer IDs a different color per number but no result. In the code below I am trying to make the first finger blue then when another finger begins drawing it would turn red. Currently the code makes all the paint blue but when 3 fingers are on the screen it all changes red. Any help is appreciated thank you
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
if(idColor == 1)
mFingerPaint.setColor(Color.BLUE);
if(idColor == 2)
mFingerPaint.setColor(Color.RED);
for (Path completedPath : mCompletedPaths) {
canvas.drawPath(completedPath, mFingerPaint);
}
for (Path fingerPath : mFingerPaths) {
if (fingerPath != null) {
canvas.drawPath(fingerPath, mFingerPaint);
}
}
}
public boolean onTouchEvent(MotionEvent event) {
int pointerCount = event.getPointerCount();
int cappedPointerCount = pointerCount > MAX_FINGERS ? MAX_FINGERS : pointerCount;
// get pointer index from the event object
int actionIndex = event.getActionIndex();
// get masked (not specific to a pointer) action
int action = event.getActionMasked();
// get pointer ID
int id = event.getPointerId(actionIndex);
idColor = id;
if ((action == MotionEvent.ACTION_DOWN || action == MotionEvent.ACTION_POINTER_DOWN) && id < MAX_FINGERS)
{
mFingerPaths[id] = new Path();
mFingerPaths[id].moveTo(event.getX(actionIndex), event.getY(actionIndex));
}
else if ((action == MotionEvent.ACTION_POINTER_UP || action == MotionEvent.ACTION_UP) && id < MAX_FINGERS)
{
mFingerPaths[id].setLastPoint(event.getX(actionIndex), event.getY(actionIndex));
mCompletedPaths.add(mFingerPaths[id]);
mFingerPaths[id].computeBounds(mPathBounds, true);
invalidate((int) mPathBounds.left, (int) mPathBounds.top, (int) mPathBounds.right, (int) mPathBounds.bottom);
mFingerPaths[id] = null;
}
for(int i = 0; i < cappedPointerCount; i++) {
if(mFingerPaths[i] != null)

int index = event.findPointerIndex(i);

Good morning. I would like to ask how Can i check if the number is integer or it isn't? I work in AndroidStudio and wanted to check this condition. I've written smth like this but with no success.Application crashes.
int value = 0;
if (!et.equals(temp)) {
value = Integer.parseInt(temp);
}
if (value != 0 && value < 10 && value > 1 && (value -(int)value!=0)) {
You can check it like this:
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String inputNumber = editText.getText().toString();
if (inputNumber.contains(".")) {
editText.setError("Your Error Message Here");
} else {
int num = Integer.parseInt(inputNumber);
// you got your interger ...
}
}
});
And use android:inputType="numberDecimal" in your EditText .
Is it possible to change the default option all column filters? I'm pretty sure I can accomplish this with some JavaScript, but I'd like to know if there's any way within the Acumatica framework to change this.
The answer will be no. The filter is inside the PX.Web.UI.dll in the PXGridFilter class which is an internal class. The property that you are interested in is the Condition.
The value is set inside one of the private methods of the PXGrid class. The code of the method is below:
private IEnumerable<PXGridFilter> ab()
{
List<PXGridFilter> list = new List<PXGridFilter>();
if (this.FilterID != null)
{
Guid? filterID = this.FilterID;
Guid guid = PXGrid.k;
if (filterID == null || (filterID != null && filterID.GetValueOrDefault() != guid))
{
using (IEnumerator<PXResult<FilterRow>> enumerator = PXSelectBase<FilterRow, PXSelect<FilterRow, Where<FilterRow.filterID, Equal<Required<FilterRow.filterID>>, And<FilterRow.isUsed, Equal<True>>>>.Config>.Select(this.DataGraph, new object[]
{
this.FilterID.Value
}).GetEnumerator())
{
while (enumerator.MoveNext())
{
FilterRow row = enumerator.Current;
string dataField = row.DataField;
PXCache pxcache = PXFilterDetailView.TargetCache(this.DataGraph, new Guid?(this.FilterID.Value), ref dataField);
if (this.Columns[row.DataField] != null)
{
List<PXGridFilter> list2 = list;
int valueOrDefault = row.OpenBrackets.GetValueOrDefault();
string dataField2 = row.DataField;
string dataField3 = row.DataField;
int value = (int)row.Condition.Value;
object value2 = pxcache.ValueFromString(dataField, row.ValueSt);
string valueText = row.ValueSt.With((string _) => this.Columns[row.DataField].FormatValue(_));
object value3 = pxcache.ValueFromString(dataField, row.ValueSt2);
string value2Text = row.ValueSt2.With((string _) => this.Columns[row.DataField].FormatValue(_));
int valueOrDefault2 = row.CloseBrackets.GetValueOrDefault();
int? #operator = row.Operator;
int num = 1;
list2.Add(new PXGridFilter(valueOrDefault, dataField2, dataField3, value, value2, valueText, value3, value2Text, valueOrDefault2, #operator.GetValueOrDefault() == num & #operator != null));
}
}
return list;
}
}
}
if (this.FilterRows != null && this.FilterRows.Count > 0)
{
for (int i = 0; i < this.FilterRows.Count; i++)
{
PXFilterRow row = this.FilterRows[i];
list.Add(new PXGridFilter(row.OpenBrackets, row.DataField, row.DataField, (int)row.Condition, row.Value, row.Value.With(delegate(object _)
{
if (this.Columns[row.DataField] == null)
{
return _.ToString();
}
return this.Columns[row.DataField].FormatValue(_);
}), row.Value2, row.Value2.With(delegate(object _)
{
if (this.Columns[row.DataField] == null)
{
return _.ToString();
}
return this.Columns[row.DataField].FormatValue(_);
}), row.CloseBrackets, row.OrOperator));
}
}
return list;
}
UPDATE
The below JS code allows you to change the condition of the last set filter:
px_all.ctl00_phG_grid_fd.show();
px_all.ctl00_phG_grid_fd_cond.items.items[7].setChecked(true);
px_all.ctl00_phG_grid_fd_ok.element.click();
px_all.ctl00_phG_grid_fd_cond.items.items[7].value "EQ"
px_all.ctl00_phG_grid_fd_cond.items.items[8].value "NE"
px_all.ctl00_phG_grid_fd_cond.items.items[9].value "GT"
px_all.ctl00_phG_grid_fd_cond.items.items[13].value "LIKE"
px_all.ctl00_phG_grid_fd_cond.items.items[14].value "LLIKE"
px_all.ctl00_phG_grid_fd_cond.items.items[15].value "RLIKE"
px_all.ctl00_phG_grid_fd_cond.items.items[16].value "NOTLIKE"
px_all.ctl00_phG_grid_fd_cond.items.items[18].value "ISNULL"
px_all.ctl00_phG_grid_fd_cond.items.items[19].value "ISNOTNULL"
I have tried to implement pagination for my custom processing screen but not getting all the required values in the grid.
If I am using below code, where I did not implemented pagination and directly using BQL in the foreach() loop for getting the records, I am getting all the applicable values.
public PXCancel<KNPIPaymentFilter> cancel;
public PXFilter<KNPIPaymentFilter> KNPIFilter;
[PXFilterable]
public PXFilteredProcessing<SOOrder, KNPIPaymentFilter> KNPIProcessOrders;
protected bool _PayMethodChanged = false;
protected bool _PayActionChanged = false;
public virtual void KNPIPaymentFilter_RowUpdated(PXCache sender, PXRowUpdatedEventArgs e)
{
_PayMethodChanged = !sender.ObjectsEqual<KNPIPaymentFilter.paymentMethodID>(e.Row, e.OldRow);
_PayActionChanged = !sender.ObjectsEqual<KNPIPaymentFilter.payPalInvAction>(e.Row, e.OldRow);
}
public IEnumerable kNPIProcessOrders()
{
if (_PayMethodChanged || _PayActionChanged)
KNPIProcessOrders.Cache.Clear();
KNPIPaymentFilter filter = PXCache<KNPIPaymentFilter>.CreateCopy(KNPIFilter.Current);
if (filter.PayPalInvAction == KNPIConstants.SL)
yield break;
foreach (SOOrder order in PXSelect<SOOrder, Where<SOOrder.orderType, Equal<SOOrderTypeConstants.salesOrder>, And<SOOrder.paymentMethodID, Equal<Required<KNPIPaymentFilter.paymentMethodID>>,
And<SOOrder.status, NotEqual<SOOrderStatus.completed>>>>>.Select(this, this.KNPIFilter.Current.PaymentMethodID))
{
KNPIPayments PayPalPayment = new PXSelect<KNPIPayments, Where<KNPIPayments.acmOrderNbr, Equal<Required<KNPIPayments.acmOrderNbr>>,
And<KNPIPayments.acmOrderType, Equal<Required<KNPIPayments.acmOrderType>>>>, OrderBy<Desc<KNPIPayments.lineNbr>>>
(this).SelectWindowed(0, 1, order.OrderNbr, order.OrderType);
if (filter.PayPalInvAction == KNPIConstants.RE)
{
if (PayPalPayment == null || (PayPalPayment != null && PayPalPayment.PayPalInvoiceStatus == KNPIConstants.CANCELLED))
yield return order;
}
else if (filter.PayPalInvAction == KNPIConstants.CH)
{
if (PayPalPayment != null && PayPalPayment.PayPalInvoiceStatus == KNPIConstants.SENT)
yield return order;
}
}
KNPIProcessOrders.Cache.IsDirty = false;
}
But when I am implementing pagination logic like below, I am not getting any of the record in the grid. I have debugged the code and found out in the list object it is loading only 19 records initially but after that other records are not at all loading in the object.

}

And<SOOrder.paymentMethodID, Equal<Optional<KNPIPaymentFilter.paymentMethodID>>>>>>(this);
int startRow = PXView.StartRow;
int totalRows = 0;
List<object> list = cmd.View.Select(new[] { KNPIFilter.Current }, null, PXView.Searches,
PXView.SortColumns, PXView.Descendings, PXView.Filters, ref startRow, PXView.MaximumRows, ref totalRows);
foreach (SOOrder order in list)
{

Can someone please help me out, as what I am doing wrong or what I am missing here.
I need to find out if a native linux application window is maximized or minimized in a java program.
I tried using X11.XGetWindowProperty() and I get some results also, but I cant make out any useful information in it.
I am using JNA 4.2.1, Java 8 update72 on Ubuntu 14.04 LTS. Any pointers will be very helpful. Thanks in advance to all.
[Edit]
I have the code below which gives me the result I need. But the result is not same for every invocation. The atoms which are returned for the window vary within invocations. Is there any other reliable way to get the window state?
