从应用程序调用默认主屏幕

我需要从我的应用程序调用手机附带的默认主屏幕，这也是一个主屏幕应用程序。我尝试搜索并发现此

    ArrayList<Intent> intentList = new ArrayList<Intent>();
    Intent intent=null;
    final PackageManager packageManager=getPackageManager();
    for(final ResolveInfo resolveInfo:packageManager.queryIntentActivities(new 
                  Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_HOME), 
                                                        PackageManager.MATCH_DEFAULT_ONLY)) {
    intent=packageManager.getLaunchIntentForPackage(
                          resolveInfo.activityInfo.packageName);
    intentList.add(intent);
    }

代码适用于所有其他启动器，但不适用于默认启动器。我尝试在代码中使用断点，发现在列表的 0 索引处应该有默认启动器意图，但意图不保存该值。我需要某种许可吗谢谢

I need to call the default home screen that comes with my phone from my application which is also a home screen app. I've tried searching and find this

    ArrayList<Intent> intentList = new ArrayList<Intent>();
    Intent intent=null;
    final PackageManager packageManager=getPackageManager();
    for(final ResolveInfo resolveInfo:packageManager.queryIntentActivities(new 
                  Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_HOME), 
                                                        PackageManager.MATCH_DEFAULT_ONLY)) {
    intent=packageManager.getLaunchIntentForPackage(
                          resolveInfo.activityInfo.packageName);
    intentList.add(intent);
    }

this code is working for the all the other launchers but not for the default launcher. I tried using break points in code and found that at 0 index of list there should be default launcher intent but intent does'nt hold the value. Do I need some kind of permission
thanks

希望这能行。

 Intent startMain = new Intent(Intent.ACTION_MAIN);
        startMain.addCategory(Intent.CATEGORY_HOME);
        startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(startMain);

Hope this will do.

 Intent startMain = new Intent(Intent.ACTION_MAIN);
        startMain.addCategory(Intent.CATEGORY_HOME);
        startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(startMain);

您可以简单地从 ResolveInfo 获取名称和类，然后像 sonyercisson 一样手动创建意图，包名称为“com.sonyericsson.home”，类为“com.sonyericsson.home.HomeActivity”，

   Intent intent = new Intent();
   intent.setClassName("com.sonyericsson.home", "com.sonyericsson.home.HomeActivity");
   intent.addCategory(Intent.CATEGORY_LAUNCHER);
   startActivity(intent);

它可以工作

you can just simple get the name and class from ResolveInfo and make intent manualy like for sonyercisson the package name is "com.sonyericsson.home" and class is "com.sonyericsson.home.HomeActivity"

   Intent intent = new Intent();
   intent.setClassName("com.sonyericsson.home", "com.sonyericsson.home.HomeActivity");
   intent.addCategory(Intent.CATEGORY_LAUNCHER);
   startActivity(intent);

it works
