我尝试过这个.

        @Override
        public void onValueSelected(Entry e, int dataSetIndex, Highlight h) {
            Log.i("Entry", String.valueOf(e));
        }

        @Override
        public void onNothingSelected() {

        }
    });

我也尝试过

或OnChartGestureListener，但我不知道如何获取相应栏的标签.

or OnChartGestureListener too, I tried but I don't know how to get the label of the corresponding bar.

推荐答案

对于OnChartValueSelectedListener，您可以

barChart.setOnChartValueSelectedListener(new OnChartValueSelectedListener() {
        @Override
        public void onValueSelected(Entry e, int dataSetIndex, Highlight h) {
            String value = barChart.getBarData().getXVals().get(e.getXIndex());
        }

        @Override
        public void onNothingSelected() {

        }
    });

以类似的方式，您也可以为其他听众实现这一目标.

In the similar way you can achieve this for other listeners too.
