2. 使用

1. 在app/build.gradle下:

dependencies {
    compile 'com.github.warkiz.widget:indicatorseekbar:1.1.2'
}

2. 在布局文件或java类中:

xml

Java

IndicatorSeekBar indicatorSeekBar = new IndicatorSeekBar.Builder(this)
                .setMax(200)
                .setMin(0)
                .setProgress(35)
                .setSeekBarType(IndicatorSeekBarType.DISCRETE_TICKS)
                .setTickType(TickType.OVAL)
                .setTickColor(Color.parseColor("#0000FF"))
                .setTickSize(8)//dp size
                .setTickNum(8)
                .setBackgroundTrackSize(2)//dp size
                .setBackgroundTrackColor(Color.parseColor("#666666"))
                .setProgressTrackSize(3)//dp size
                .setProgressTrackColor(Color.parseColor("#0000FF"))
                .showIndicator(true)
                .setIndicatorType(IndicatorType.SQUARE_CORNERS)
                .setIndicatorColor(Color.parseColor("#0000FF"))
                .build();

3. 功能

3.1 多种的SeekBar类型

IndicatorSeekBar 提供了两种系列的类型:

连续（continuous）的滑动: CONTINUOUS/CONTINUOUS_TEXTS_ENDS.
非连续（discrete）的滑动: DISCRETE_TICKS/ DISCRETE_TICKS_TEXTS/ DISCRETE_TICKS_TEXTS_ENDS.

<com.warkiz.widget.IndicatorSeekBar
    app:isb_seek_bar_type="continuous"
    .../>

3.2 自定义颜色、尺寸

SeekBar以下部分的颜色或尺寸可以被自定义：

背景条 track_background_bar
进度条 track_progress_bar
刻度 tick
刻度文字 text
滑块 thumb
指示器 indicator
指示器文字 indicator_text

3.3 隐藏刻度tick

SeekBar的两个端点的刻度或者滑块左边的刻度可以被隐藏。

<com.warkiz.widget.IndicatorSeekBar
    app:isb_tick_both_end_hide="true"
    .../>

<com.warkiz.widget.IndicatorSeekBar
    app:isb_tick_on_thumb_left_hide="true"
    .../>

3.4 给SeekBar选择圆角/方角

默认两端是圆角，可以设置为方形。

<com.warkiz.widget.IndicatorSeekBar
    app:isb_track_rounded_corners="true"
    .../>

3.5 滑块thumb下显示进度

当 seekabr 的类型为 CONTINUOUS or DISCRETE_TICKS时 , 可以设置滑动后滑块下显示保留进度。

<com.warkiz.widget.IndicatorSeekBar
    app:isb_seek_bar_type="continuous"//discrete_ticks
    app:isb_thumb_progress_stay="true"
    .../>

3.6 自定义SeekBar两端的文字text

当 seekabr 的类型是 CONTINUOUS_TEXTS_ENDS 或 DISCRETE_TICKS_TEXTS_ENDS 时, 可以设置两端的文字.

<com.warkiz.widget.IndicatorSeekBar
    app:isb_seek_bar_type="continuous_texts_ends"//discrete_ticks_texts_ends
    app:isb_text_left_end="last"
    app:isb_text_right_end="next"
    .../>

3.7 自定义刻度下的文字text

当 seekabr 的类型是 DISCRETE_TICKS_TEXTS , 可以通过设置数组的方式自定义刻度下的文字, 数组的长度应当和刻度相等。

<com.warkiz.widget.IndicatorSeekBar
    app:isb_text_array="@array/texts_below_tick_length_5"
    app:isb_tick_num="5" //一般来说 , 文字数组的长度应该和刻度的数量相等
    .../>

or
indicatorSeekBar.setTextArray(R.array.texts_below_tick_length_5);

3.8 自定义滑块thumb的图片

滑块可以使用图片去自定义：

<com.warkiz.widget.IndicatorSeekBar
    app:isb_thumb_drawable="@mipmap/ic_launcher"
    .../>

3.9 自定义刻度tick的图片

刻度可以使用图片去自定义.

<com.warkiz.widget.IndicatorSeekBar
    app:isb_tick_drawable="@mipmap/ic_launcher"
    .../>

3.10 自定义指示器indicator

IndicatorSeekbar提供了3种指示器的类型： ROUNDED_CORNERS / SQUARE_CORNERS / CUSTOM,当指示器的类型为 CUSTOM 时, 可以自定义指示器的view.

<com.warkiz.widget.IndicatorSeekBar
    app:isb_indicator_type="custom"
    app:isb_indicator_custom_layout="@layout/indicator"
    .../>

or
indicatorSeekBar.setCustomIndicator(R.layout.indicator);

注意：如果自定义指示器需要显示进度, 那么指示器必须要有一个TextView，而且其id必须设置为isb_progress.

3.11 自定义指示器顶部的内容

当 indicator 的类型为 ROUNDED_CORNERS 或者 SQUARE_CORNERS , 可以设置指示器顶部的view.

<com.warkiz.widget.IndicatorSeekBar
    app:isb_indicator_type="rounded_corners"//square_corners
    app:isb_indicator_custom_top_content_layout="@layout/top_content_view"
    .../>

or
indicatorSeekBar.getIndicator().setIndicatorTopContentLayout(R.layout.top_content_view);

注意：如果自定义指示器顶部的view需要显示进度, 那么这个view必须要有一个TextView，而且其id必须设置为isb_progress.

4. 支持进度监听

indicatorSeekBar.setOnSeekChangeListener(new IndicatorSeekBar.OnSeekBarChangeListener() {

    @Override
    public void onProgressChanged(IndicatorSeekBar seekBar, int progress, float progressFloat, boolean fromUserTouch) {

    }

    @Override
    public void onSectionChanged(IndicatorSeekBar seekBar, int thumbPosOnTick, String textBelowTick, boolean fromUserTouch) {
        //only callback on discrete series SeekBar type.
    }

    @Override
    public void onStartTrackingTouch(IndicatorSeekBar seekBar, int thumbPosOnTick) {
    }

    @Override
    public void onStopTrackingTouch(IndicatorSeekBar seekBar) {

    }
});

onSectionChanged: 当SeekBar的类型为非连续 discrete系列时, 这个回调会获得滑块的位置和滑块下的文字. 当为连续 continuous系列则不回调。

5. 混淆配置

-keep class com.warkiz.widget.** { *; }
