1、找出所有的category为laucher的Activity ，即寻找所有有入口Activity的APP

Intent launcherIntent=new Intent(Intent.ACTION_MAIN,null);

launcherIntent.addCategory(Intetnt.CATEGORY_LAUNCHER);

PackageManager pm=this.getPackageManager();

List<ResolveInfo> list=pm.queryIntentActivities(launcherIntent,0);

2、收集每个APP的图标和名字

for(ResolveInfo mResolveInfo:list){

Drawable icon=mResolveInfo.loadIcon(pm);

String name=mResolveInfo.loadLable(pm);

}

3、点击时，跳转到相应的APP

ResolveInfo mResolveInfo=list.get(position);

//String className=mResolveInfo.activityInfo.name;

String classPackage=mResolveInfo.activityInfo.packageName;

Intent intent=pm.getLaunchIntentForPackage(classPackage);

startActivity(intent);

ps:具体的应用列表怎么显示，按照需求而定吧。可以好好研究一下LauncherActivity,后面继续深入
