android top 排序,android dialog根据弹窗等级排序显示

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：
