I have problem with to fast moving of rows in my RecyclerView.
if i moving with them that fast so one get moved faster thatn other two of them propably... than manytimes my background is left there... sometimes even whole view...(propably if i move with my finger a bit back which cancale onswipe...)
Is there any solution to this bug?
or am i stupid and did something badly...
ItemTouchHelper.SimpleCallback preparedSimpleCallback = new ItemTouchHelper.SimpleCallback(0,ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {
#Override
public boolean onMove(#NonNull RecyclerView recyclerView, #NonNull RecyclerView.ViewHolder viewHolder, #NonNull RecyclerView.ViewHolder target) {
return false;
}
#Override
public void onSwiped(#NonNull RecyclerView.ViewHolder viewHolder, int direction) {
final int position = viewHolder.getAdapterPosition();
switch (direction) {
case ItemTouchHelper.RIGHT:
preparedToCompleted(viewHolder.getLayoutPosition(), false);
break;
case ItemTouchHelper.LEFT:
preparedToProcessing(viewHolder.getLayoutPosition(), false);
break;
}
}
#Override
public void onChildDraw(#NonNull Canvas c, #NonNull RecyclerView recyclerView, #NonNull RecyclerView.ViewHolder viewHolder, float dX, float dY, int actionState, boolean isCurrentlyActive) {
new RecyclerViewSwipeDecorator.Builder(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive)
.addSwipeLeftBackgroundColor(ContextCompat.getColor(getActivity(), R.color.blue_link))
.addSwipeLeftActionIcon(R.drawable.ic_delete_white_24dp)
.addSwipeRightBackgroundColor(ContextCompat.getColor(getActivity(), R.color.colorAccent))
.addSwipeRightActionIcon(R.drawable.ic_launcher_foreground)
.create()
.decorate();
super.onChildDraw(c, recyclerView, viewHolder, dX, dY, actionState, isCurrentlyActive);
}
};
This is itemtoutch helper... and on swipe it call long void which start is :
public void preparedToCancelled (int position, Boolean error) {
final JSONObject row = (JSONObject) preparedRecycler.Apirows.get(position);
if (mainActivity.addAction()) {
final Long id = (Long) row.get("id");......
and notifying by this:
for (int x = 0; x < preparedRecycler.Apirows.size(); ++x) {
JSONObject y = (JSONObject) preparedRecycler.Apirows.get(x);
if (y.get("id") == id) {
preparedRecycler.Apirows.remove(x);
//preparedRecycler.notifyItemRemoved(x);
preparedRecycler.notifyDataSetChanged();
}
}
i tryed notifying both removed and dataSetChange are having this isue...
enter image description here
Refreshing or adding new row to crashed position does not repair that background
UPDATE:
I checked that view position and it is actualy -1 which means it does not existed... how can i prevented that.. ? i can not even remove that row becouse of that

Hello I have a problem between the double and int
my code "works" when I put the variables in int but I do not have the numbers after the decimal point as soon as I put in duplicate it puts the result to me at 0 and I do not see why
MyCartAdpter
public class MyCartAdapter extends RecyclerView.Adapter<MyCartAdapter.ViewHolder> {
Context context;
List<MyCartModel> list;
double totalAmount =0;
...
}
#Override
public void onBindViewHolder(#NonNull ViewHolder holder, int position) {
...
holder.totalPrice.setText(String.valueOf(list.get(position).getTotalPrice()));
//total amount pass to cart activity
totalAmount = (totalAmount + list.get(position).getTotalPrice());
Intent intent = new Intent("MyTotalAmount");
intent.putExtra("totalAmount",totalAmount);
LocalBroadcastManager.getInstance(context).sendBroadcast(intent);
}
MyCartModel
public class MyCartModel {
...
double totalPrice;
...
}
public MyCartModel(..., double totalPrice, ...) {
...
this.totalPrice = totalPrice;
...
}
public double getTotalPrice() {
return totalPrice;
}
public void setTotalPrice(double totalPrice) {
this.totalPrice = totalPrice;
}
and my CartActivity
public BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
double totalBill = intent.getIntExtra("totalAmount",0);
overAllAmount.setText("Montant Total :"+totalBill+"€");
}
};
thank you for your help because for 24 hours I have been looking
overAllAmount.setText(String.format("%.2f",totalBill));
Could also put the textviews input type to numberdecimal
android:inputType="numberDecimal"
Happy coding
I have three edittext values for which i am using textwatcher to update data.
I want that if i enter any value in anyone of the edit text then according to that value it should calculate and then update the edittext in which i entered the value automatically and after that set the value in other specif edit text and save the final value in string if need to send to any server.

I have tried to set my try catch code in aftertextChanged but at first it was giving me numberformatexception as soon as i enter a text above my contion my app crash but after that i tried using try catch to catch a numberformatexception after that i am able to add number above my condition and even after a long wait nothing happen can any one explain where i am going wrong.
I am learning custom views in android.
I made one custom view, with a rectangle and a text. The code of the custom view is:
public class TileGenerator extends View {
// rectangle parameters
private Rect rect = new Rect();
private Paint rectPaint = new Paint();
private Integer rectEndX;
private Integer rectEndY;
private Integer rectStartX;
private Integer rectStartY;
private Integer rectFillColor;
private Float rectTextStartX;
private Float rectTextStartY;
//rectangle text
private String rectText;
private Paint rectTextPaint = new Paint();
public TileGenerator(Context context) {
super(context);
}
#Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
public void setTileTitleText(String rectText) {
this.rectText = rectText;
}
#Override
protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
super.onLayout(changed, left, top, right, bottom);
rectEndX = getrectEndX();
rectEndY = getrectEndY();
rectStartX = getRectStartX();
rectStartY = getRectStartY();
rectTextStartX = rectEndX/4f + rectStartX;
rectTextStartY = 3.5f * rectEndY/4f + rectStartY;
rectTextPaint.setTextSize(rectEndY/8);
rectTextPaint.setColor(Color.BLACK);
rect.set(rectStartX,rectStartY,rectEndX,rectEndY);
rectPaint.setColor(getRectFillColor());
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.drawRect(rect, rectPaint);
canvas.drawText(rectText,rectTextStartX,rectTextStartY,rectTextPaint );
}
#Override
protected void onDetachedFromWindow() {
super.onDetachedFromWindow();
}
public Integer getrectEndX() {
return rectEndX;
}
public void setrectEndX(Integer rectEndX) {
this.rectEndX = rectEndX;
}
public Integer getrectEndY() {
return rectEndY;
}
public void setrectEndY(Integer rectEndY) {
this.rectEndY = rectEndY;
}
public Integer getRectStartX() {
return rectStartX;
}
public void setRectStartX(Integer rectStartX) {
this.rectStartX = rectStartX;
}
public Integer getRectStartY() {
return rectStartY;
}
public void setRectStartY(Integer rectStartY) {
this.rectStartY = rectStartY;
}
public Integer getRectFillColor() {
return rectFillColor;
}
public void setRectFillColor(Integer rectFillColor) {
this.rectFillColor = rectFillColor;
}
public String getRectText() {
return rectText;
}
}
After that I created an blank activity. I am doing all with JAVA code. No XML. Then I try to add above custom view to a gridview layout. I want to add two custom views with different text in a horizontal gridview. So far my code is as below:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
GridLayout gridLayout = new GridLayout(this);
// first custom view
CustomRectWithText customRectWithText = new CustomRectWithText(this);
customRectWithText.setRectEndX(200);
customRectWithText.setRectEndY(200);
customRectWithText.setRectStartX(2);
customRectWithText.setRectStartY(2);
customRectWithText.setImage(image);
customRectWithText.setRectText("Text");
customRectWithText.setRectFillColor(Color.BLUE);
gridLayout.addView(customRectWithText);
// second custom view
CustomRectWithText customRectWithText1 = new CustomRectWithText(this);
customRectWithText1.setRectEndX(400);
customRectWithText1.setRectEndY(200);
customRectWithText1.setRectStartX(200 + 5);
customRectWithText1.setRectStartY(2);
customRectWithText1.setTileTitleText("Text 1");
customRectWithText1.setRectFillColor(Color.GREEN);
gridLayout.addView(customRectWithText1);
setContentView(gridLayout);
}
But still I am not getting both of the rectangles in a grid view. Only one rectangle is displayed at a time. In above case only first custom view is displayed.
Where am I doing wrong.
All I want is to make a repetitive rectangle of varying labels of any size inside a grid view.
Is this the way to do it. I mean is there any other way around.
I dont want to use ListItems.
Sorry but i do not have enough repo to comment.
But why dont you make an adapter?
Gridview behaves same as listView.
Use adapter to fill your grid.
This is the proper way to populate listView and gridView also.
i have some problem with this method. it works fine, but with one little problem. there is too little time among i call this method. so only the last String is printed on a label. but i want that the next String starting printed, only after previous String is finished.
Sorry for my English((
public void some(final String s) {
final Animation animation = new Transition() {
{
setCycleDuration(Duration.millis(2000));
}
protected void interpolate(double frac) {
final int length = s.length();
final int n = Math.round(length * (float) frac);
javafx.application.Platform.runLater(new Runnable() {
#Override
public void run() {
status.setValue(s.substring(0, n));
}
}
);
}
};
animation.play();
}
Use the following code to get a typewriting effect.
public void AnimateText(Label lbl, String descImp) {
String content = descImp;
final Animation animation = new Transition() {
{
setCycleDuration(Duration.millis(2000));
}
protected void interpolate(double frac) {
final int length = content.length();
final int n = Math.round(length * (float) frac);
lbl.setText(content.substring(0, n));
}
};
animation.play();
}
I don't know if it is an effect that you are trying to achieve, but I have created (ugly) demo how you can do this with TimeLine
public class Main extends Application {
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception {
IntegerProperty letters= new SimpleIntegerProperty(0);
Label label = new Label();
Button animate = new Button("animate");
letters.addListener((a, b, c) -> {
label.setText("animate".substring(0, c.intValue()));
});
animate.setOnAction((e)->{
Timeline timeline = new Timeline();
KeyValue kv = new KeyValue(letters, "animate".length());
KeyFrame kf = new KeyFrame(Duration.seconds(3), kv);
timeline.getKeyFrames().add(kf);
timeline.play();
});
BorderPane pane = new BorderPane(label, null, null, animate, null);
primaryStage.setScene(new Scene(pane, 300,300));
primaryStage.show();
}
}
I am trying to build a button with a progress bar which is displayed in the center of the button and instead of text, as soon as the button is tapped, and while some background processing takes place.
What I am doing is to have a custom button and set the animatable as a drawable left to the button, and in onDraw to move the animatable in the center of the button. However, for a short period of time after the button is tapped, I do not know why there are 2 progress bars on the button.
public class ButtonWithProgressBar extends Button {
protected int progressId = R.drawable.progress_bar;
protected Drawable progress;
protected CharSequence buttonText;
#Override
public void setText(CharSequence text, BufferType type) {
super.setText(text, type);
if (Strings.notEmpty(text)) {
buttonText = text;
}
}
public void startSpinning()
{
if(isSpinning()){
return;
}
progress = getContext().getResources().getDrawable(progressId);
final Drawable[] old = getCompoundDrawables();
setCompoundDrawablesWithIntrinsicBounds(old[0], old[1], progress, old[3]);
setEnabled(false);
if(progress instanceof Animatable){
((Animatable)progress).start();
}
setText("");
}
public void stopSpinning()
{
if(!isSpinning()){
return;
}
if(progress instanceof Animatable){
((Animatable)progress).stop();
}
setEnabled(true);
setText(buttonText);
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
if (progress != null) {
final int drawableHeight = progress.getIntrinsicHeight();
final int drawableWidth = progress.getIntrinsicWidth();
final int drawableTop = (getHeight() - drawableHeight) / 2;
final int drawableLeft = (getWidth() - drawableWidth) / 2;
progress.setBounds(drawableLeft, drawableTop, drawableLeft + drawableWidth, drawableTop + drawableHeight);
progress.draw(canvas);
}
}
}
And this is displayed for a short period after tap, before everything looking as I want:
Any ideas why this is happening?
Found the problem.Updated code to a working version.
