Question

我正在尝试将字符串作为url从Fragment发送到Activity并在webview内部加载url活动。但是我尝试了很多而且没有成功。

这是我的片段代码

intent.putExtra("url", "http://www.ekantipur.com/");
            startActivity(intent);

我的网页浏览活动包含

package com.nepalpolice.nepalinews;

公共类Web扩展了AppCompatActivity {

WebView webview;
ProgressBar pbar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_web);

    String url = getIntent().getStringExtra("url");


    webview = (WebView)findViewById(R.id.webView1);
    pbar = (ProgressBar)findViewById(R.id.progressBar1);
    webview.setWebViewClient(new WebViewClient());
    webview.getSettings().setLoadsImagesAutomatically(true);
    webview.getSettings().setJavaScriptEnabled(true);
    webview.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
    webview.loadDataWithBaseURL(url, null, null, null, null);
}

public class WebViewClient extends android.webkit.WebViewClient
{
    @Override
    public void onPageStarted(WebView view, String url, Bitmap favicon) {

        // TODO Auto-generated method stub
        super.onPageStarted(view, url, favicon);
    }

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {

        // TODO Auto-generated method stub
        view.loadUrl(url);
        return true;
    }
    @Override
    public void onPageFinished(WebView view, String url) {

        // TODO Auto-generated method stub

        super.onPageFinished(view, url);
        pbar.setVisibility(View.GONE);
        webview.setVisibility((View.VISIBLE));

    }
}


@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if ((keyCode == KeyEvent.KEYCODE_BACK) && webview.canGoBack()) {
        webview.goBack();
        return true;
    }
    else
    {
        finish();
    }
    return super.onKeyDown(keyCode, event);

}

}

显示进度条，然后显示空白屏幕。提前谢谢。

Answer 1

试试这个

而不是这个

 webview.loadDataWithBaseURL(url, null, null, null, null);

像这样使用

web.loadUrl(url);

并确保通过在日志中打印获取正确的URL。

Answer 2

super.onCreate(savedInstanceState);
setContentView(R.layout.main);
web = (WebView) findViewById(R.id.webview);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://appgeyser.com/");    
}

It is very simple. Use this for load url.

将字符串作为url传递并在webView中加载
