ExpandedController中直播Current time显示异常，如何重载或隐藏该控件？

Got it, let's tackle this problem with the ExpandedController's incorrect Current Time display in your live streaming scenario. Here are two practical approaches—either hiding the control entirely or overriding it to fix the time display properly:

If you don't need the Current Time display at all, you can easily hide it with these steps:

• First, locate the ID of the Current Time TextView in your ExpandedController layout. For common media player libraries like ExoPlayer, this is often R.id.exo_current_time.
• In your activity or fragment where you initialize the player, grab a reference to this view and set its visibility to GONE:

// Kotlin example
val currentTimeView = playerView.findViewById<TextView>(R.id.exo_current_time)
currentTimeView.visibility = View.GONE

// Java example
TextView currentTimeView = playerView.findViewById(R.id.exo_current_time);
currentTimeView.setVisibility(View.GONE);

• Alternatively, if you're using a custom ExpandedController layout file, you can directly set android:visibility="gone" on the Current Time TextView in XML to avoid runtime code changes.

If you want to keep the Current Time but fix its incorrect value (common in live streams where default logic shows offset instead of wall-clock time), you can override the controller's update logic:

• Create a custom class that extends your base ExpandedController (e.g., PlayerControlView for ExoPlayer) and override the method responsible for updating progress/time:

class CustomLiveExpandedController(context: Context, attrs: AttributeSet?) : PlayerControlView(context, attrs) {
    override fun updateProgress() {
        super.updateProgress()
        player?.let { livePlayer ->
            // For live streams, calculate the actual wall-clock time if needed
            val currentLivePosition = livePlayer.currentPosition
            // Adjust with live offset if your stream uses it
            val correctedTime = currentLivePosition - (livePlayer.currentLiveOffset ?: 0)
            
            // Update the Current Time TextView with formatted corrected time
            findViewById<TextView>(R.id.exo_current_time)?.text = formatLiveTime(correctedTime)
        }
    }

    private fun formatLiveTime(timeMs: Long): String {
        // Implement your preferred time formatting logic here
        val totalSeconds = (timeMs / 1000).toInt()
        val hours = totalSeconds / 3600
        val minutes = (totalSeconds % 3600) / 60
        val seconds = totalSeconds % 60
        
        return if (hours > 0) {
            String.format("%d:%02d:%02d", hours, minutes, seconds)
        } else {
            String.format("%02d:%02d", minutes, seconds)
        }
    }
}

• Replace the default controller in your layout XML with this custom one:

<com.your.app.package.CustomLiveExpandedController
    android:id="@+id/live_player_controller"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:playerView="@id/your_player_view"/>

• This gives you full control over how the Current Time is calculated and displayed, ensuring it's accurate for your live streaming use case.
