注意

　　不美观，只是应急用。

代码

webview.setWebViewClient(new WebViewClient() {
    @Override
    public void onPageCommitVisible(WebView view, String url) {
        super.onPageCommitVisible(view, url);

        // 先将高度缩回
        LinearLayout.LayoutParams lp1 = (LinearLayout.LayoutParams) webview.getLayoutParams();
        lp1.height = WRAP_CONTENT;
        webview.setLayoutParams(lp1);
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        super.onPageFinished(view, url);

        // 再根据内容高度设置 WebView 高度
        webview.measure(0, 0);
        LinearLayout.LayoutParams lp2 = (LinearLayout.LayoutParams) webview.getLayoutParams();
        lp2.height = webview.getMeasuredHeight();
        webview.setLayoutParams(lp2);
    }
});
