如何在进度条中隐藏exoplayer缓冲区指示器(查看栏)？

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import com.google.android.exoplayer2.ui.DefaultTimeBar;
import com.google.android.exoplayer2.ui.PlayerControlView;

public class CustomExoPlayerView extends PlayerControlView {

    private DefaultTimeBar bufferIndicator;

    public CustomExoPlayerView(Context context) {
        super(context);
    }

    public CustomExoPlayerView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomExoPlayerView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onFinishInflate() {
        super.onFinishInflate();
        // 找到缓冲区指示器的视图
        bufferIndicator = findViewById(R.id.exo_buffering);
        // 隐藏缓冲区指示器
        bufferIndicator.setVisibility(View.GONE);
    }
}
