Answer 1

试试这个

String localPath = path.toString();
 localPath  = localPath.replace(" ", "%20").trim();

并像这样使用

WebView webView = (WebView)findViewById(R.id.documentView);
        webView.invalidate();
        webView.getSettings().setJavaScriptEnabled(true);
        webView.getSettings().setLoadWithOverviewMode(true);
        webView.getSettings().setUseWideViewPort(true);
        webView.loadData("file:///"+localPath,"application/pdf", "UTF-8");
