建议把FrameLayout 用一个自定义FrameLayout 来实现, 可以让使用方继承

[budaowengd]

` private ByWebView(Builder builder) {
this.activity = builder.mActivity;
this.mErrorTitle = builder.mErrorTitle;
this.mErrorLayoutId = builder.mErrorLayoutId;

    FrameLayout parentLayout = new FrameLayout(activity);
    // 设置WebView
    setWebView(builder.mCustomWebView);
    parentLayout.addView(mWebView, new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
    // 进度条布局
    handleWebProgress(builder, parentLayout);
    if (builder.mIndex != -1) {
        builder.mWebContainer.addView(parentLayout, builder.mIndex, builder.mLayoutParams);
    } else {
        builder.mWebContainer.addView(parentLayout, builder.mLayoutParams);
    }`

[youlookwhat]

private ByWebView(Builder builder) {
	this.activity = builder.mActivity;
	this.mErrorTitle = builder.mErrorTitle;
	this.mErrorLayoutId = builder.mErrorLayoutId;
	FrameLayout parentLayout = new FrameLayout(activity);
	// 设置WebView
	setWebView(builder.mCustomWebView);
	parentLayout.addView(mWebView, new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
	// 进度条布局
	handleWebProgress(builder, parentLayout);
	if (builder.mIndex != -1) {
		builder.mWebContainer.addView(parentLayout, builder.mIndex, builder.mLayoutParams);
	} else {
		builder.mWebContainer.addView(parentLayout, builder.mLayoutParams);
	}
}

你具体是有什么需求呢，我可以调整一下，可以给个场景我做个示例啥的

他要求你将ByWebView 做成AdvancedWebView 那样是个webView, 可以在Layout 里面直接调用,也可以进一步继承。
