无法 运行 SplashScreen 和 OnBoarding 屏幕在一起
Couldn't run SplashScreen and OnBoarding screen together
当我 运行 我的应用程序时，我看不到任何 Splash Screen.I 从视频中执行此操作，并且我已将我的 AndroidManifest 设置设置为视频中的设置。我将我的 SplashScreen 放在 Manifest 文件中 MainActivity 的顶部并将其设置为正常（就像我创建我的启动画面时一样activity）但它仍然不起作用。

SplashScreen 必须是您的启动器 activity。您的启动器 IntroActivity activity。更新了您的 AndroidManifest.xml

我是 android 的新手，我的解决方案可能不像您通常认为的那样是正确的解决方案。首先抱歉我的英语不好。在我看来，启动画面是介绍您和您的应用程序的唯一且优雅的方式。它必须快速且持续时间短。我在互联网上找到了很多解决方案，但所有页面和所有片段的 90% 都是相同的（似乎很多人都在同一个第一个解决方案上进行了剪切/粘贴）。所以我决定实施我自己的解决方案。对不起我的原始代码。我已经实现了所有功能 Activity：在您的应用中，您只需插入以下修改：
-) 第一步：activity_main.xml（主布局），全部包含在一个FrameLayout中：
<androidx.drawerlayout.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:visibility="invisible"
tools:openDrawer="start">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:id = "@+id/frameContainer">
<include
layout="@layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
<com.google.android.material.navigation.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="@layout/nav_header_main"
app:menu="@menu/activity_main_drawer" />
</androidx.drawerlayout.widget.DrawerLayout>
目标 FrameLayout (@id/frameContainer) 是闪屏容器。
-) 第二步：在drawable目录下插入一张位图，应该是启动画面背景，在我的例子中我还准备了一个矩形space，插入我的动态字符串（例如“touch开始”和“版本号 000.00.00”）。我的位图id是“@drawable/applogothumb”，同样在字符串文件中，我插入了一个字符串“@string/toccasplash”。在位图上，我还为字符串取了矩形 space 的像素坐标。
-) 第三步：在主应用中声明和使用：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Util.hideStatusBar(this);
setContentView(R.layout.activity_main);
//Qui lancio la thumb, il controllo passato [ frameContainer ] deve essere
//un FrameLayout in modo che la thumb stia sopra tutto il resto
CMainSplashBox thumb = new CMainSplashBox(this,
R.id.frameContainer, //FrameLayout ID Step 1
R.drawable.applogothumb, //Bitmap ID Step 2
R.string.toccasplash, //Stringa ID
CVersions.APP_VERSION, //Version number (String)
//pixel coordinate of the rectangular space for the strings
new Rect(TWRITE_ORG_X,TWRITE_ORG_Y,TWRITE_END_X,TWRITE_END_Y),
//Time duration in seconds
10);
mCsd = new CSerializeData(this);
mCsd.loadConfiguration();
....
....
如您所见，所有内容都在 CMainSplashBox class 中进行管理。我不需要其他任何东西。同时显示启动画面，应用程序可以完成构建代码并继续执行。
一切都在 class 中，管理点击关闭它和计时器计时。
class 在这里。在你看到 class 之前，请记住这是我的第一个实验，里面的代码是为我自己的范围编写的，但我认为它有工作的材料，或者有人可以建议我如何改进这个想法...

如您所见，所有内容都在 CMainSplashBox class 中进行管理。我不需要其他任何东西。同时显示启动画面，应用程序可以完成构建代码并继续执行。 一切都在 class 中，管理点击关闭它和计时器计时。 class 在这里。在你看到 class 之前，请记住这是我的第一个实验，里面的代码是为我自己的范围编写的，但我认为它有工作的材料，或者有人可以建议我如何改进这个想法...
