android.widget.AbsoluteLayout $的LayoutParams不能转换到android.widget.FrameLayout $的LayoutParams

我在定制的web视图增加了进度，但是当我滚动视图，它导致该错误

这是我的onScrollChanged方法：

@Override 
protected void onScrollChanged(int left, int top, int oldLeft, int oldTop) { 
     LayoutParams layoutParams = (LayoutParams) progressbar.getLayoutParams(); 
     layoutParams.leftMargin = left; 
     layoutParams.topMargin = top; 
     progressbar.setLayoutParams(layoutParams); 
     super.onScrollChanged(left, top, oldLeft, oldTop); 
    }

这是我进口：

import com.fccs.library.R; 
import com.fccs.library.callback.SingleButtonCallBack; 
import com.fccs.library.notice.DialogUtils; 
import com.tencent.smtt.export.external.interfaces.JsResult; 
import com.tencent.smtt.sdk.WebSettings; 
import com.tencent.smtt.sdk.WebView; 
import android.annotation.SuppressLint; 
import android.content.Context; 
import android.content.Intent; 
import android.net.Uri; 
import android.util.AttributeSet; 
import android.view.KeyEvent; 
import android.view.View; 
import android.widget.ProgressBar;
