Android跳转新Activity后Splash Screen仍显示的问题求助

Hey there! Let's work through why your splash screen is sticking around and covering your new Activity—this is a super common pitfall for Android beginners, so don't worry, we'll get it sorted. Since you followed the "Splash Screen right way" guide, here are the most likely issues to check:

• Double-check your Activity themes in AndroidManifest.xml
  It's easy to accidentally apply the splash screen theme to your main Activity by mistake. Open your AndroidManifest.xml and make sure:

  • Your Splash Activity uses the dedicated splash theme (e.g., @style/SplashTheme)
  • Your main Activity uses your app's regular theme (e.g., @style/AppTheme) instead of the splash one.

  Example correct configuration:

  <activity
      android:name=".SplashActivity"
      android:theme="@style/SplashTheme">
      <intent-filter>
          <action android:name="android.intent.action.MAIN" />
          <category android:name="android.intent.category.LAUNCHER" />
      </intent-filter>
  </activity>
  
  <activity
      android:name=".MainActivity"
      android:theme="@style/AppTheme" /> <!-- No splash theme here! -->
  

• Ensure your Splash Activity calls finish() after navigating
  If you forget to finish the Splash Activity when launching your main Activity, it'll stay in the task stack and its background might still show through. Make sure your Splash Activity's navigation code includes finish():

  Example in Kotlin:

  class SplashActivity : AppCompatActivity() {
      override fun onCreate(savedInstanceState: Bundle?) {
          super.onCreate(savedInstanceState)
          // No need for setContentView—your splash theme handles the background
          Handler(Looper.getMainLooper()).postDelayed({
              val intent = Intent(this, MainActivity::class.java)
              startActivity(intent)
              finish() // Critical: closes the Splash Activity
          }, 1000)
      }
  }
  

• Verify your splash theme is only for the splash screen
  Your splash theme should only define the windowBackground for the splash screen, and your main app theme should override this with a normal background. Check your styles.xml:

  Splash theme:

  <style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
      <item name="android:windowBackground">@drawable/your_splash_drawable</item>
  </style>
  

  Main app theme:

  <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
      <item name="android:windowBackground">@color/white</item>
      <!-- Your other theme customizations -->
  </style>
  

• Clean and rebuild your project
  Sometimes Android Studio's build cache can cause old theme settings to stick around. Go to Build > Clean Project, then Build > Rebuild Project to rule out caching issues.

If none of these fix it, feel free to share your AndroidManifest.xml and styles.xml code snippets—we can dig deeper!
