Just use a better solution, e.g. this one [Indefinite-Pager-Indicator](https://github.com/rbro112/Android-Indefinite-Pager-Indicator) 3 | 4 | # BubblePagerIndicator 5 | A view pager indicator view to deal with a large amount of pages. Nice scale and transition animations are supported. 6 | 7 | Sample 8 | 9 | Usage 10 | ----- 11 | 12 | 1. Add mavenCentral() to repositories block in your gradle file. 13 | 2. Add `implementation 'com.github.shuhart:bubblepagerindicator:1.2.0'` to your dependencies. 14 | 3. Add `BubblePageIndicator` into your layouts or view hierarchy: 15 | 16 | ```xml 17 | 31 | 32 | ``` 33 | 34 | 4. Attach indicator to the ViewPager instance: 35 | 36 | ```java 37 | pager = findViewById(R.id.pager); 38 | indicator = findViewById(R.id.indicator); 39 | adapter = new ViewPagerAdapter(); 40 | pager.setAdapter(adapter); 41 | indicator.setViewPager(pager); 42 | ``` 43 | An adapter should be attached to the ViewPager before calling indicator.setViewPager(pager). 44 | 45 | 5. You can customize the behavior in runtime: 46 | ```java 47 | indicator.setOnSurfaceCount(3); 48 | indicator.setRisingCount(2); 49 | // resolved color 50 | indicator.setFillColor(ContextCompat.getColor(this, R.color.colorAccent)); 51 | // resolved color 52 | indicator.setPageColor(ContextCompat.getColor(this, R.color.colorPrimary)); 53 | // in px 54 | indicator.setRadius(getResources().getDimensionPixelSize(R.dimen.default_bubble_indicator_radius)); 55 | // in px 56 | indicator.setMarginBetweenCircles(getResources().getDimensionPixelSize( 57 | R.dimen.default_bubble_indicator_circles_margin)); 58 | ``` 59 | 60 | ## Customization 61 | | Attribute| Description | Default Value | 62 | |-----------------------|-----------------------|--------| 63 | | bpi_pageColor | Current page circle color. | #FFFFFF | 64 | | bpi_fillColor | Circles color | #000000 | 65 | | bpi_radius | Normal circle radius. | 3dp | 66 | | bpi_marginBetweenCircles | Margin between centers of circles. | 3dp | 67 | | bpi_onSurfaceCount | A number of circles with full radius (bpi_radius) | 5 | 68 | | bpi_risingCount | A number of scaled circles. | 2 | 69 | 70 | Maximum number of circles visible to the user is *bpi_onSurfaceCount* + *bpi_risingCount* * 2 (Default is 9). 71 | At the beginning only *bpi_onSurfaceCount* + *bpi_risingCount* (Default is 7) circles are visible. 72 | Radius for a rising circle is scaled by power of 2 with some correction applied. 73 | In every aspect the library is mimicking the Instagram indicator behavior. 74 | 75 | ## Special thanks 76 | @tree1891 for his help in fixing many annoying issues. 77 | 78 | License 79 | ======= 80 | 81 | Copyright 2017 Bogdan Kornev. 82 | 83 | Licensed under the Apache License, Version 2.0 (the "License");
