Question

我想在这样的范围栏中显示时间。我希望其时间格式的最小值和最大值如HH：mm样式。我正在获得输出但不完美。我想从早上6点到晚上11:59设定我的价值。

我在哪里弄错了？我希望我的日期在15分钟间隔，如6:00 - ＆gt; 6:15 - ＆GT; 6:30 - > 6:45 ......等等

我所做的就是这里。

活动类

enter code   // Gets the RangeBar
    rangebar = (RangeBar) findViewById(R.id.rangebar1);
    rangebar.setTickCount(25 * SMALLEST_HOUR_FRACTION);//SMALLEST_HOUR_FRACTION = 4;
    rangebar.setTickHeight(0);
    rangebar.setThumbRadius(8);
    rangebar.setConnectingLineWeight(3);



    // Sets the display values of the indices
    rangebar.setOnRangeBarChangeListener(new RangeBar.OnRangeBarChangeListener() {
        @Override
        public void onIndexChangeListener(RangeBar rangeBar, int leftThumbIndex, int rightThumbIndex) {
            DecimalFormat deciFormat= new DecimalFormat("00");

            leftIndexValue.setText("" + leftThumbIndex);
            rightIndexValue.setText("" + rightThumbIndex);

            int minHour = leftThumbIndex / SMALLEST_HOUR_FRACTION;
            int minMinute = SMALLEST_HOUR_FRACTION * (leftThumbIndex % SMALLEST_HOUR_FRACTION);
            int maxHour = rightThumbIndex / SMALLEST_HOUR_FRACTION;
            int maxMinute = SMALLEST_HOUR_FRACTION * (rightThumbIndex % SMALLEST_HOUR_FRACTION);
            leftIndexValue.setText(minHour + ":" + minMinute);
            rightIndexValue.setText(maxHour + ":" + maxMinute);

            leftIndexValue.setText(deciFormat.format(minHour) + ":" + deciFormat.format(minMinute));
            rightIndexValue.setText(deciFormat.format(maxHour) + ":" + deciFormat.format(maxMinute));
        }
    });

Answer 1

设置setNotifyWhileDragging选项

 rangebar = (RangeBar) findViewById(R.id.rangebar1);
        rangebar.setTickCount(25 * SMALLEST_HOUR_FRACTION);//SMALLEST_HOUR_FRACTION = 4;
        rangebar.setTickHeight(0);
        rangebar.setThumbRadius(8);
        rangebar.setConnectingLineWeight(3);
        rangebar.setNotifyWhileDragging(true);

并设置onRangeSeekBarValuesChanged Listener

  rangebar.setOnRangeSeekBarChangeListener(new RangeSeekBar.OnRangeSeekBarChangeListener<Integer>() {
        @Override
        public void onRangeSeekBarValuesChanged(RangeSeekBar<?> bar, Integer minValue, Integer maxValue) {
          // set bar value And Text
        }
    });

Answer 2

我认为根据拇指指数计算小时和分钟是错误的。有一个适当的计算：

hours = thumb / SMALLEST_HOUR_FRACTION; // SMALLEST_HOUR_FRACTION should be defined as int
minute = (thumb % SMALLEST_HOUR_FRACTION) * (60 / (float) SMALLEST_HOUR_FRACTION);

我相信您应该将最大范围指定为rangebar.setTickCount（24 * SMALLEST_HOUR_FRACTION）; （每天24小时）。

但是有一种更好的格式化日期和时间的方法。看一下Calendar和SimpleDateFormat类：Android Format calendar to output time

在Seek Range Bar中以HH：MM格式设置时间
