1.直接上代码~

private void loadApps() {
        Intent intent = new Intent(Intent.ACTION_MAIN, null);
        intent.addCategory(Intent.CATEGORY_LAUNCHER);
        List<ResolveInfo> apps = getPackageManager().queryIntentActivities(intent, 0);
        //for循环遍历ResolveInfo对象获取包名和类名
        for (int i = 0; i < apps.size(); i++) {
            ResolveInfo info = apps.get(i);
            String packageName = info.activityInfo.packageName;
            CharSequence cls = info.activityInfo.name;
            CharSequence name = info.activityInfo.loadLabel(getPackageManager());
            Log.e("！！！！！", name + "----" + packageName + "----" + cls);
        }
    }
