Fix FloatingX control operations timing issue by implementing operation queuing for all control methods

Open Copilot opened this issue 4 months ago • 3 comments

FloatingX control operations called in Activity.onCreate() were being silently ignored due to lifecycle timing issues. The floating window's internal view hadn't been initialized yet when these operations were called, causing them to fail.

Problem

When calling FloatingX.control().xxx operations in onCreate(), several issues occurred:

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    
    FloatingX.install { /* config */ }
    
    // These operations were ignored:
    FloatingX.control("main").move(700f, 700f)        // Line 202 - ignored
    FloatingX.control("main").hide()                  // Line 203 - ignored
    FloatingX.control("main").updateViewContent {     // Also ignored
        holder.setText(R.id.tvItemFx, "Updated!")
    }
    
    showMenu1() // Move operation ignored on first call
    hideMenu1() // No move animation shown
}

private fun showMenu1() {
    FloatingX.control("b1").moveByVector(150f, 0f) // Ignored first time
    FloatingX.control("b1").show()                 // Works but no move
}

private fun hideMenu1() {
    FloatingX.control("b1").move(300f, 300f) // Ignored
    FloatingX.control("b1").hide()           // Hides immediately without animation
}

Root Cause

Operations like move(), show(), hide(), and updateViewContent() depend on the floating window's internal view being created and attached. However, when called in onCreate(), the Activity lifecycle callbacks that initialize the floating window haven't been triggered yet, resulting in internalView being null and operations being silently ignored.

Solution

Implemented a comprehensive operation queuing mechanism that:

  1. Queues all control operations when the floating window isn't ready (internal view is null)
  2. Executes queued operations automatically when the platform provider completes initialization
  3. Maintains operation order to ensure consistent behavior
  4. Handles edge cases with thread safety and duplicate operation detection

Key Changes

  • FxQueuedOperation.kt: New sealed class for operation types (Show, Hide, Move, MoveByVector, UpdateViewContent)
  • FxBasisControlImp.kt: Added thread-safe operation queuing with executePendingOperations() for all affected methods
  • FxAppPlatformProvider.kt: Triggers pending operation execution after app-level floating window initialization
  • FxSystemPlatformProvider.kt: Triggers pending operation execution after system-level floating window initialization

Affected Operations

All control operations that depend on the floating window being ready are now queued:

  • show() - Queued when internal view not ready
  • hide() - Queued when internal view not ready
  • move() / moveByVector() - Queued when internal view not ready
  • updateViewContent() - Queued when viewHolder not ready

Result

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    
    FloatingX.install { /* config */ }
    
    // These now work correctly:
    FloatingX.control("main").move(700f, 700f)        // ✅ Executes when ready
    FloatingX.control("main").hide()                  // ✅ Executes when ready
    FloatingX.control("main").updateViewContent {     // ✅ Executes when ready
        holder.setText(R.id.tvItemFx, "Updated!")
    }
    
    showMenu1() // ✅ Moves then shows properly
    hideMenu1() // ✅ Shows move animation before hiding
}

Backward Compatibility

  • ✅ No API changes required
  • ✅ Existing code continues to work unchanged
  • ✅ Minimal performance impact (only affects operations called during initialization)
  • ✅ Thread-safe implementation prevents race conditions

Testing

Added comprehensive test activities:

  • TestLifecycleActivity.kt - Demonstrates the fix for the original issue including updateViewContent()
  • EdgeCaseTestActivity.kt - Tests rapid operations, duplicates, cancellation, etc.

Fixes #195.

@copilot updateViewContent() 是不是忘了考虑了

@copilot updateViewContent() 是不是忘了考虑了

You're absolutely right! I added updateViewContent() to the operation queuing system. It had the same timing issue where it would fail silently when called before the floating window's viewHolder was ready. Now it gets queued and executed properly when the window is initialized. Fixed in commit 8ee8ac9.
