Series line width is changed if animation is cut off about android-decoview-charting HOT 6 CLOSED

@bmarrdev Do you have any feedback on this matter?

from android-decoview-charting.

I was unable to reproduce this issue. I will take another look at this when I get a chance. It would be helpful if you could share a gist of an activity that exhibits the behaviour.

from android-decoview-charting.

I'll post the entire DecoView related code, because the rest is pretty much the default project in AS. You can copy paste this inside an empty project and it's the same thing. I've even increased the animation durations in order to make it easier to spot.

double total = 3500;
double partial = 2570;
int percentage = (int) (partial * 100 / total);

mDecoView = (DecoView) findViewById(R.id.activity_main_decoview);

mDecoView.addSeries(new SeriesItem.Builder(ContextCompat.getColor(MainActivity.this, R.color.color_gray))
                .setSeriesLabel(new SeriesLabel.Builder(total + " USD")
                        .setColorBack(ContextCompat.getColor(MainActivity.this, R.color.color_gray_darker))
                        .setColorText(ContextCompat.getColor(MainActivity.this, R.color.color_gray))
                        .setTypeface(Typeface.create("sans-serif-light", Typeface.NORMAL))
                        .build())
                .setRange(0, 100, 100)
                .setInitialVisibility(false)
                .setLineWidth(32f)
                .build());

final SeriesItem seriesItem = new SeriesItem.Builder(ContextCompat.getColor(MainActivity.this, R.color.colorPrimary))
                .setSeriesLabel(new SeriesLabel.Builder(partial + " USD")
                        .setColorBack(ContextCompat.getColor(MainActivity.this, R.color.color_gray_darker))
                        .setColorText(ContextCompat.getColor(MainActivity.this, R.color.color_gray))
                        .setTypeface(Typeface.create("sans-serif-light", Typeface.NORMAL))
                        .build())
                .setRange(0, 100, 0)
                .setInitialVisibility(false)
                .setLineWidth(32f)
                .setCapRounded(true)
                .setShowPointWhenEmpty(true)
                .build();

int seriesIndex = mDecoView.addSeries(seriesItem);

mDecoView.executeReset();
mDecoView.addEvent(new DecoEvent.Builder(DecoEvent.EventType.EVENT_SHOW, true)
                .setDelay(1000)
                .setDuration(3000)
                .build());
mDecoView.addEvent(new DecoEvent.Builder(percentage).setIndex(seriesIndex).setDelay(4000).setDuration(2000).build());

Now then, the test case is the following:

1. Cold start MainActivity, so that onCreate() is called with the code above.
2. As soon as you see the series with the colorPrimary color appear and start growing as part of the show animation, immediately tap the Home button.
3. Wait for the remaining of the animation to complete (~4s).
4. Enter the app again (not cold start).

If you tap the Home button before the animation starts or after it ends, then everything will look fine, so if you don't get it right the first try, try some more. However, if you got the timing right, the result should look pretty similar to the initial screenshot. I presume the grow animation incorrectly sets the second series line width if the animation is interrupted, which isn't good.

Thanks for that info. I will investigate it this weekend and report back.

I have reproduced the issue. I couldn't see an immediate reason for it, but as soon as I get some free time I will find and post a fix. An option for you to work around this issue for now recreate the DecoView and set the positions or events required in your Activity onResume()

from android-decoview-charting.

I have included a fix for this issue in a new build, v0.9.6.

To access this fix update your gradle dependencies:
compile 'com.github.bmarrdev:android-DecoView-charting:v0.9.6'
