Question

我试图通过轻按另一个开关来更改开关的状态及其实现。我尝试了但是失败了。有人可以帮忙吗？

这是我的Activity.java

//first switch

flw_Rate_switch.setOnCheckedChangeListener(new 

CompoundButton.OnCheckedChangeListener() {

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)  {

            if (isChecked) {

                    //lqd_followed_switch.setOnCheckedChangeListener(null);

          //lqd_followed_switch.setChecked(!lqd_followed_switch.isChecked());

                    flow_rate_switch_txt.setTextColor(Color.RED);

                    mlineData = generateLineData(rate);
                    data.setData(mlineData);
                    combinedChart.setData(data);

                    combinedChart.setVisibleXRangeMaximum(4); // allow 4 values to be displayed at once on the x-axis, not more
                    combinedChart.moveViewToX(4);
                    combinedChart.animateY(2000);
                    combinedChart.invalidate();


                } else {
                    //elseFlowRate();
                    flow_rate_switch_txt.setTextColor(Color.BLACK);
                    String label = "Flow Rate";

                    boolean indicator = data.removeDataSet(lineData1.getDataSetByLabel(label, true));
                    combinedChart.notifyDataSetChanged();
                    combinedChart.invalidate();
                    combinedChart.animateX(1000);
                }
            }

        });


//2nd switch


        lqd_followed_switch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {

                 lqd_followed_switch_txt.setTextColor(getColor(R.color.colorPrimary));



                    mlineData = generateLineData1(foll);
                    data.setData(mlineData);
                    combinedChart.setData(data);

                    combinedChart.setVisibleXRangeMaximum(4); // allow 4 values to be displayed at once on the x-axis, not more
                    combinedChart.moveViewToX(4);
                    combinedChart.animateY(2000);
                    combinedChart.invalidate();

                } else {

                    lqd_followed_switch_txt.setTextColor(Color.BLACK);

                    String label = "Liquid Followed";
                    boolean indicator = data.removeDataSet(lineData2.getDataSetByLabel(label, true));
                    combinedChart.notifyDataSetChanged();
                    combinedChart.invalidate();

                }
            }

        });

当我点击第一个开关时，它运行“ if”块，同时，当我点击第二个开关时，它运行第二个开关的“ if”块，但它不能一直运行开关第一个的“ if”子句块而不是它应该自动运行开关1st的“ else”块。

CompoundButton.OnCheckedChangeListener()

是事件侦听器，表示如果未发生（选中或未选中）事件，则不会触发它。

如果要更新其他UI组件，则应调用以下内容：

flw_Rate_switch.setChecked(false);

或

flw_Rate_switch.setChecked(true);

切换状态更改无效-Android
