android dialog根据弹窗等级排序显示的示例代码
背景:由于主界面可能弹窗很多弹窗,需求要求某个dialog必须在前面显示,如果再消失监听中,线性判断,每个dialog都去判断工作量巨大,且不易阅读。所以做了一个弹窗排序的项目。这里只是讲解单个activity中的弹窗排序,demo中还有维护多个activity 弹窗排序,详细看最下面github
做到工具组件化,不侵入原项目代码,无需继承,使用方便。
原理:当有一个dialog添加显示时,判断等级是否大于,大于则显示,否则则添加到等待队列
private void show(int level, Dialog dialog, DialogInterface.OnDismissListener onDismissListener){ if(dialog == null){ return; } DialogLevelModel topDialog = getTopShowingDialog(); DialogLevelModel inModel = new DialogLevelModel(level, dialog, activity); new DismissListenerBinder(inModel,this,onDismissListener).bind(); if(topDialog ==null || level >= topDialog.level){ realShow(inModel); }else { waitList.sortAdd(new DialogLevelModel(level, dialog, activity)); } }
添加集合中要根据等级排序
public boolean sortAdd(DialogLevelModel inModel){ Log.e("DLArrayList","add---"+inModel.level); int lastSize = size(); if(lastSize == 0){ return super.add(inModel); } int index = 0; for (int i = size()-1; i >=0; i--){ DialogLevelModel temp = get(i); if(inModel.level >= temp.level){ index = i+1; break; } } super.add(index,inModel); return true; }
显示的时候,判断activity是否存在,整理集合
private void realShow(DialogLevelModel dialogLevelModel){ waitList.remove(dialogLevelModel); showList.add(dialogLevelModel); if(dialogLevelModel.activity != null && dialogLevelModel.activity.get() != null && !dialogLevelModel.activity.get().isFinishing()){ dialogLevelModel.dialog.show(); }else{ destory(); } }
收到dialog消失监听,整理集合,判断最上层dialog 和等待队列dialog等级对比
@Override public void onDismiss(DialogLevelModel dialogLevelModel) { for(int i = showList.size()-1;i>=0;i--){ if(showList.get(i).dialog == dialogLevelModel.dialog){ showList.remove(i); break; } } boolean flag =true; while (flag) { if(waitList.size() == 0){ break; } DialogLevelModel tempModel = waitList.get(waitList.size() -1); if (getTopShowingDialog() == null) { realShow(tempModel); } else if (tempModel.level >= getTopShowingDialog().level) { realShow(tempModel); } else { break; } } }
调用:
for(int i = 0;i<15;i++){ final int level2 = (int)(1+Math.random()*1000); final Dialog dialog2 = showCommonDialog("content:level-"+level2); Log.e("dialoglevl","level:"+level2); if(i ==13){ dialogLevelManager.showDelay(level2,2000,dialog2,MainActivity.this); continue; } if(i ==14){ dialogLevelManager.showDelay(level2,3000,dialog2,MainActivity.this); continue; } dialogLevelManager.show(level2,dialog2,MainActivity.this); }
结果展示:
这里只是单个activity中添加排列显示dialog的部分重要代码,要想要全部代码,下面github
DialogLevel如果感觉有用,请star哦
