英文:
Couldn't run SplashScreen and OnBoarding screen together
问题
当我运行我的应用程序时，我看不到任何启动画面。我是从一个视频中学习的，我已经按照视频上的方式设置了我的AndroidManifest设置。我在清单文件中将我的启动画面定位在MainActivity之上，并将其设置为正常（就像我创建启动画面活动时一样），但它仍然不起作用。
我的AndroidManifest.xml：
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.labawsrh.aws.introscreen">
<application

<activity android:name=".MainActivity" />

SplashScreen.java：
public class SplashScreen extends AppCompatActivity {
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash_screen);
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Intent i = new Intent(SplashScreen.this, MainActivity.class);
startActivity(i);
finish();
}
}, 3000);
}
}

When I run my app, I can't see any Splash Screen.I did this from a video and I have set my AndroidManifest settings just like the one on the video. I located my SplashScreen on top of the MainActivity in Manifest file and set it to normal(just like the when I created my splash screen activity) but it still doesn't work.

英文:
I am new on android, and my solution could be not as normally you think is the right solution. First sorry for my bad english. In my opinion, the splash screen is only and elegant way for introduce you and your app. It must be fast and a short duration. I red a lot of solutions in internet but all pages and all snippets are at 90% the same (seems that many peoples have made cut / paste on the same first solution). So I decided to implement my own solution. Sorry for my raw code. I have implemented all in one Activity: and in your app you have to insert only this modifications:
-) Step one: activity_main.xml (main layout), include all in a FrameLayout:
<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>
The target FrameLayout (@id/frameContainer) is the splash screen container.
-) Step two: insert a bitmap in drawable directory, it should be the splash screen background, and in my example I have prepared also a rectangular space where insert my dynamic strings (for example "touch for start" and "Version n. 000.00.00"). My bitmap id is "@drawable/applogothumb", same in the string file, I have inserted a string "@string/toccasplash". On the bitmap I have also took the pixel coordinate of the rectangular space for the strings.
-) Step three: declaration and usage in the Main App:
@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();
....
....
As you can see all is managed in the CMainSplashBox class. Nothing else i required. In the meanwhile the Splash screen is displayed the app can finisc to build the code and continue the execution.
All is in the class, the managing on the click for close it and the timer for the time count.
The class is here. Before you see the class, remember that this is my first experiment and the code inside is made for my own scope but I think there is materia for work on it or, may be, someone can suggest me how improve this Idea...

SplashScreen必须是您的启动活动。您的启动活动是IntroActivity。已更新您的AndroidManifest.xml。
<?xml version="1.0" encoding="utf-8"?>

<activity android:name=".interests" />
<!-- 设置 SplashScreen 为启动活动 -->
<activity android:name=".SplashScreen">
