本应用中打开其他的程序
一、使用Intent的setComponent方法
Intent intent = new Intent();
intent.setComponent(new ComponentName(“包名”, “包名.主类名”));
intent.setAction(Intent.ACTION_VIEW);
startActivity(intent);
二、使用包管理器
Intent intent = new Intent();
intent = getPackageManager().getLaunchIntentForPackage(“包名”);
startActivity(intent);

可以根据(packageInfo.applicationInfo.flags&ApplicationInfo.FLAG_SYSTEM)判断其是不是为0可以判断是不是系统程序
//显示非系统软件 if((packageInfo.applicationInfo.flags&ApplicationInfo.FLAG_SYSTEM)==0){
map.put("img", packageInfo.applicationInfo.loadIcon(getPackageManager()).getCurrent());
map.put("name", packageInfo.applicationInfo.loadLabel(getPackageManager()).toString());
map.put("desc", packageInfo.packageName);
listMap.add(map);
}
