Android Studio 3.1.2中DataBinding跳转至XML功能失效求助

dataBinding {
    enabled = true
}

}

Also, verify your **project-level** `build.gradle` has the correct dependencies and repositories. Your snippet only includes a private Maven repo, but you’ll need the standard Google/JCenter repos for the Android Gradle plugin to fetch Data Binding resources:
```gradle
buildscript {
    repositories {
        google()
        jcenter()
        maven { url 'https://mav...' } // Keep your private repo here
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2' // Must match your Studio version
        // No extra Data Binding classpath needed—this plugin includes it
    }
}

Cached build artifacts are the #1 culprit for wonky IDE features:

• Go to Build > Clean Project to wipe old build files
• Then run Build > Rebuild Project to generate fresh artifacts
• Finally, restart Android Studio to ensure the IDE picks up the new files

If a rebuild doesn’t fix it, Studio’s internal index might be corrupted:

• Go to File > Invalidate Caches / Restart
• Select Invalidate and Restart—this will clear the IDE’s cached indexes and force a full re-scan of your project

Sometimes subtle XML issues can break Binding Class generation (even if the project compiles):

• Open your Data Binding layout files and confirm they’re wrapped in a <layout> tag correctly
• Check the Build tab in Studio for any Data Binding-related warnings/errors (like mismatched variable types or missing classes)
• Verify the generated Binding Class exists in app/build/generated/data_binding_base_class_source_out—if it’s missing, that means the class never generated properly

If all else fails, try toggling the Data Binding setting to force a re-sync:

• Remove the dataBinding { enabled = true } block from your module-level build.gradle
• Sync your project (File > Sync Project with Gradle Files)
• Add the block back in and sync again

This often fixes hidden configuration glitches that a regular sync misses.
