如何格式化 android-range-seek-bar 的最小值和最大值？

我使用 android-range-seek-bar 控件https://github.com/anthem/android-range-seek-bar https://github.com/anothem/android-range-seek-bar显示两个拇指控件，允许选择范围。

我希望指示条上所选最小值和最大值的文本格式为“hh:mm:ss”，我创建了一个函数ConvertSecondsToHMmSs， 我怎样才能做到这一点？如1000L显示“00:00:01”

更多，我希望在最小值或最大值改变时做一些事情，但只有事件public void onRangeSeekBarValuesChanged(RangeSeekBar<?> bar, Long minValue, Long maxValue)，它无法区分哪个值（最小值或最大值）发生了变化。我希望能够做到A当最小值改变时，做B当最大值改变时！

Code

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        RangeSeekBar<Long> seekBar = (RangeSeekBar<Long>) findViewById(R.id.myRangeSeekBar);
        seekBar.setRangeValues(1000L,2000L);
}


private String ConvertSecondsToHMmSs(long millis) {
        return String.format("%02d:%02d:%02d",
                TimeUnit.MILLISECONDS.toHours(millis),
                TimeUnit.MILLISECONDS.toMinutes(millis) -
                        TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
                TimeUnit.MILLISECONDS.toSeconds(millis) -
                        TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));
}

Layout

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:rsb="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin"
    tools:context=".MainActivity">

    <TextView android:text="@string/hello_world" android:layout_width="wrap_content"
        android:layout_height="wrap_content" />


    <org.florescu.android.rangeseekbar.RangeSeekBar
        android:id="@+id/myRangeSeekBar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        rsb:absoluteMaxValue="150"
        rsb:absoluteMinValue="20"/>

</RelativeLayout>

构建.gradle

apply plugin: 'com.android.application'
android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.example.cuiwei.myapplication"
        minSdkVersion 21
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'org.florescu.android.rangeseekbar:rangeseekbar-library:0.3.0'

}

这相当简单，尽管您需要修改原始内容RangeSeekBar:

1.

• Copy RangeSeekBar类到你的项目中

• 添加您的convertSecondsToHMmSs进入你的习惯RangeSeekBar class

• In onDraw的方法RangeSeekBar:

  替换（第 646-647 行）

      String minText = String.valueOf(getSelectedMinValue());
      String maxText = String.valueOf(getSelectedMaxValue());
  

  with

      String minText;
      String maxText;
      if (getSelectedMinValue() instanceof Long && getSelectedMaxValue() instanceof Long) {
          minText = String.valueOf(convertSecondsToHMmSs((Long)getSelectedMinValue()));
          maxText = String.valueOf(convertSecondsToHMmSs((Long)getSelectedMaxValue()));
      } else {
          minText = String.valueOf(getSelectedMinValue());
          maxText = String.valueOf(getSelectedMaxValue());
      }
  

  （当然，这可以推广到更广泛的用途！）

2. 要区分最小/最大边界变化 - 只需存储以前的值并比较它们：

    Long currentMin = 1000L, currentMax = 2000L;

    ......

    RangeSeekBar rangeSeekBar = (RangeSeekBar)findViewById(R.id.myRangeSeekBar);
    rangeSeekBar.setRangeValues(currentMin, currentMax);
    rangeSeekBar.setOnRangeSeekBarChangeListener(new RangeSeekBar.OnRangeSeekBarChangeListener() {
        @Override
        public void onRangeSeekBarValuesChanged(RangeSeekBar bar, Object minValue, Object maxValue) {
            if (!currentMin.equals(minValue)) {
                Toast.makeText(MainActivity.this, "Min border changed", Toast.LENGTH_SHORT).show();
            }

            if (!currentMax.equals(maxValue)) {
                Toast.makeText(MainActivity.this, "Max border changed", Toast.LENGTH_SHORT).show();
            }

            currentMin = (Long)minValue;
            currentMax = (Long)maxValue;
        }
    });
