从URL打开PDF
提问于 2011-10-11 17:35:22
我是android开发的新手。我必须显示来自URL的PDF。
这是我当前的代码，但我无法显示PDF文件：
public class TestActivity extends Activity
{
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
System.setProperty("http.proxyHost","192.168.0.2");
System.setProperty("http.proxyPort","8080");
showPdf();
}
private void showPdf()
{
WebView webview = new WebView(this);
setContentView(webview);
webview.getSettings().setJavaScriptEnabled(true);
Log.v("....hello....","");
webview.loadUrl("http://docs.google.com/gview?embedded=true&url=http://myurl.com/demo.pdf");
}
}Logcat：

它在这里工作得很好。不过，我还是建议您测试一下是否在AndroidManifest.xml文件中添加了互联网权限：
<uses-permission android:name="android.permission.INTERNET"></uses-permission>更新：
您要打开的链接是：http://litofinter.es.milfoil.arvixe.com/PDF/Book6.pdf
现在它在这里也工作得很好：
