需要有一个文档模板，填写其中的字段，然后保存。所有这些都可以在 Android 应用程序中以编程方式完成。有两种选择：

  1. 有一个 .pdf 文件。填写其中的字段并保存
  2. 有一个 .doc 文件。填写其中的字段，将其转换为 .pdf 并保存。

问题是不能使用商业库，以及需要开源代码的具有许可证的库。我发现的大多数答案都很古老，我认为在这段时间里出现了新的图书馆。或者在其中查阅的库没有文档。

收到来自Google的电子邮件：

嗨 Starikov Mark 的开发人员，

经审核，（应用名称）、（应用包）因违反政策而从 Google Play 下架。在您提交合规更新之前，用户将无法使用此应用。

问题：违反使用 Android 广告 ID 政策和开发者分发协议第 4.8 节

当应用请求或处理敏感的用户或设备信息时，Google Play 要求开发者提供有效的隐私政策。我们发现您的应用会收集和传输 Android 广告标识符，这受隐私政策要求的约束。如果您的应用收集 Android 广告 ID，则您必须在 Play 管理中心的指定字段以及应用内部提供有效的隐私政策。

后续步骤：提交您的应用以供再次审核

通读 Android 广告 ID 和用户数据的使用政策以及开发者分发协议，并对您的应用进行适当的更改。如果您决定收集敏感的用户信息，请务必遵守上述政策，并在应用的商品详情页面和应用内包含指向有效隐私政策的链接。确保您的应用符合所有其他开发者计划政策。如果进一步违反政策，可能会发生额外的强制执行。登录您的 Play 管理中心并将更新提交到您的应用。或者，您可以通过删除对敏感权限或用户数据的任何请求来选择退出此要求。

如果获得批准，您的应用将再次可用，并且所有安装、评分和评论都完好无损。

如果您已查看该政策并认为此次删除可能有误，请与我们的政策支持团队联系。我的一位同事将在 2 个工作日内回复您。

感谢您帮助我们为 Google Play 用户提供清晰透明的体验。

问候，

海梅

Google Play 团队

他们检查了我在Google Play上发布的应用，发现我使用的是横幅广告 ID，但没有提供隐私政策。

问题是这样的：

  1. 我从来没有写过隐私政策，也不知道要写什么，如何格式化等等。

  2. 需要张贴URL。我没有自己的网站或博客。是否可以在GitHub 上使用该README文件，或者有更简单的方法吗？

  3. 它还需要添加到应用程序中。究竟应该在哪里添加？当您第一次启动应用程序时？在设置或“关于”部分的某个地方？

安装了 CMake（没有 CLang），添加path了cmake-3.9.2/bin.

cmake -version

作品。

有CMakeLists.txt一个文件

#cmake

cmake_minimum_required(VERSION 3.5)

project(concentration)

option(set_clang "set clang as default compiler" 0)
option(set_gpp "set g++ as default compiler" 0)
option(cros_compile "cros compile for win32" 0)

if(${UNIX})
    message(STATUS "Unix system")
elseif(${WIN32})
    message(WARNING "Work is not guaranted")
else()
    message(FATAL_ERROR "System not supported")
endif()

if(set_gpp)
    set(CMAKE_CXX_COMPILER g++)

    set(CMAKE_CXX_COMPILER i686-w64-mingw32-g++-posix)
    set(CMAKE_CXX_FLAGS "-static-libstdc++ -static-libgcc")
endif()

endif()

include_directories(${CURSES_INCLUDE_DIR})

add_executable(${PROJECT_NAME} ${MAIN_SRC} ${CONCENTRATION_SRC})

target_link_libraries(${PROJECT_NAME} ${CURSES_LIBRARIES})

一般来说，当我运行命令时

cmake
cmake -Dset_gpp=1

CMake 写道：

-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:5 (project):
  The CMAKE_C_COMPILER:

    cl

  is not a full path and was not found in the PATH.

  To use the NMake generator with Visual C++, cmake must be run from a shell
  that can use the compiler cl from the command line.  This environment is
  unable to invoke the cl compiler.  To fix this problem, run cmake from the
  Visual Studio Command Prompt (vcvarsall.bat).

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.

编译器的路径在path. g++团队正在工作。我一直从命令行编译。试图CmakeLists.txt指定一个明确的路径g++。仍然没有帮助。所有文件路径都是拉丁文。

基本上，我们需要帮助！

一般来说，我有一个带有 ViewPager 和 TabLayout 的片段。在页面上有带有文本的片段和带有 RecyclerView 的片段。所以在片段的第一次开始时，一切都正常加载。使用后退按钮退出片段并重新开始后，带有 RecyclerView 的片段停止工作。

代码： 片段：

package com.starikov.gidtj.NewTowns;

    @Override
    public void onResume() {
        super.onResume();
        getActivity().setTitle("Душанбе");
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        View view = getView();
        assert view != null;

        final TabLayout tabLayout = view.findViewById(R.id.tab_layout);
        tabLayout.addTab(tabLayout.newTab().setText("История Душанбе"));

        tabLayout.addTab(tabLayout.newTab().setText("Парки и памятники"));
        tabLayout.addTab(tabLayout.newTab().setText("Пешая прогулка по Душанбе"));

        final ViewPager viewPager = view.findViewById(R.id.pager);
        Fragment list[] = {
                new HistoryOfDushanbe(),
                new MuseumsOfDushanbe(),
                new ParksAndMonumentsOfDushanbe(),

        final TownsPagerAdapter adapter = new TownsPagerAdapter(getActivity().getSupportFragmentManager(), list);
        viewPager.setAdapter(adapter);
        viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
        viewPager.setOffscreenPageLimit(1);
        tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
            @Override
            public void onTabSelected(TabLayout.Tab tab) {
                viewPager.setCurrentItem(tab.getPosition());
            }

            @Override

    @Override
    public void destroyItem(ViewGroup viewGroup, int position, Object object) {
        super.destroyItem(viewGroup, position, object);

带有 RecyclerView 的片段：

        museumImages = new int[museums.length];
        for(int i = 0; i < museums.length; ++i) {
            museumNames[i] = museums[i].getName();
            museumDescriptions[i] = museums[i].getDescription();
            museumImages[i] = museums[i].getImageID();
        }
    }

}

我寻求帮助，否则我已经战斗了一个小时。如果您仍然需要抛出某种代码，请告诉我。提前致谢！

我RecyclerView用来显示包含项目的列表。我想使用这种方法实现搜索，最好以最简单和最有效的方式。我无法理解我在互联网上找到的那些例子，tk。对我来说很难（我还是个初学者）。
项目清单：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/textId"
        android:padding="@dimen/activity_horizontal_margin"/>

    <View
        android:layout_width="fill_parent"
        android:layout_height="1dp"
