在弹出的android中打开pdf

问题描述

我正在开发一个 Android 应用程序，我需要在弹出窗口中打开我的 pdf 文件.我的代码是:

I am developing an Android app, where I need to open my pdf file in a popup window. My code is:

ImageView brobutton=(ImageView)layout.findViewById(R.id.imageView3);
brobutton.setOnClickListener(new OnClickListener() {
                                                   }
});

我已经开发了一个应用程序，可以使用以下代码在模拟器中打开 pdf:

I already have developed an app to open pdf in emulator with this code:

final String googleDocsUrl = "http://docs.google.com/viewer?url=";
WebView mWebView=new WebView(SubProducts.this);                                         mWebView.getSettings().setJavaScriptEnabled(true);
WebSettings webSettings = mWebView.getSettings();
webSettings.setPluginState(PluginState.ON);
mWebView.setWebViewClient(new WebViewClient() {
    public boolean shouldOverrideUrlLoading(WebView view, String url){                                                          
        view.loadUrl(image_urlpdf);
        return false; // then it is not handled by default action
    }
});
mWebView.loadUrl((googleDocsUrl + image_urlpdf));

在按钮的点击下，我需要打开我的 pdf.任何人都建议我有好主意.提前致谢.

under the onclick of button I need to open my pdf.Any one suggest me with good idea. Thanks in advance.

推荐答案

您需要修改您的应用才能打开 PDF.使用意图传递一些标志以提醒您的应用需要打开弹出窗口以显示 PDF.

You need to modify your app to open PDF. Either pass some flag using intents to alert that your app need to open popup for showing PDF.
