Question

Hai dude，我开发了一个应用程序，它最初显示了游戏列表视图，假设用户点击该游戏列表视图中的足球元素，那么足球列表视图打开，如果用户选择了特定的玩家列表视图，那么它显示，我的问题是我想要2知道哪个列表视图处于活动状态。

任何人都可以帮我解决这个问题吗？

if(tabHost.getCurrentTab() == 2)
                    {  
                        Log.v("I m Here Boss","0");
                        if(findViewById(R.id.bars_school_details).getVisibility() == View.VISIBLE)
                        {
                            Log.v("I m Here Boss","1");
                            findViewById(R.id.bars_school_details).setVisibility(View.GONE);
                            findViewById(R.id.bars_list).setVisibility(View.GONE);
                            findViewById(R.id.bars).setVisibility(View.VISIBLE);
                        }
                        else if(findViewById(R.id.bars_list).getVisibility() == View.VISIBLE)
                        {
                            Log.v("I m Here Boss","2");
                            findViewById(R.id.bars_school_details).setVisibility(View.VISIBLE);
                            findViewById(R.id.bars_list).setVisibility(View.GONE);
                            findViewById(R.id.bars).setVisibility(View.GONE);
                        }

                    }

最后我得到了解决方案，我将代码更改为

try {
                    if(tabHost.getCurrentTab() == 2)
                    { 
                      try{

                            if(BS_.lv_bardate.getVisibility() == View.VISIBLE)
                            {
                                BS_Bars.lv_bardate.setVisibility(View.GONE);
                                BS_Bars.lv_barlist.setVisibility(View.GONE);
                                BS_Main.tv.setText("Schools");
                                BS_Bars.lv.setVisibility(View.VISIBLE);

                            }
                            if(BS_Bars.lv_barlist.getVisibility() == View.VISIBLE)
                            {
                                BS_Bars.lv_bardate.setVisibility(View.VISIBLE);
                                BS_Main.tv.setText("Dates");
                                BS_Bars.lv_barlist.setVisibility(View.GONE);
                                BS_Bars.lv.setVisibility(View.GONE);
                            }


    if(BS_Bars.sv.getVisibility() == View.VISIBLE)
                                {
                                    BS_Bars.lv_bardate.setVisibility(View.GONE);
                                    BS_Bars.lv_barlist.setVisibility(View.VISIBLE);


    BS_Bars.lv.setVisibility(View.GONE);
                            }



    if(BS_Bars.lv.getVisibility() == View.VISIBLE)
                                {
    //                              BS_Bars.lv_bardate.setVisibility(View.GONE);
    //                              BS_Bars.lv_barlist.setVisibility(View.GONE);
    //                              BS_Bars.lv.setVisibility(View.GONE);
                                    finish();
                                }

                            }

                        catch(Exception e)
                        {
                            Log.v("BSMain","Error in Bar Module Back Button");
                        }
                    }
