Answer 1

使用网页视图或重定向网址。

 Intent intent = new Intent(MainActivity.this, Web_view.class);
                intent.putExtra("url", "https://www.hive.co/contests/contest/5267/spotlight/");
                startActivity(intent);

在网络视图中

之后

public class Web_view extends AppCompatActivity {

    private WebView webView;
    private ProgressBar progressBar;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.web_view);
        progressBar = (ProgressBar) findViewById(R.id.progressBar_cyclic);
        String url = getIntent().getStringExtra("url");
        webView = (WebView) findViewById(R.id.webview);
        webView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);

            }

            @Override
            public void onPageFinished(WebView view, String url) {
                super.onPageFinished(view, url);
                progressBar.setVisibility(View.GONE);
            }
        });
        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true);
        webView.loadUrl(url);

        // progressBar.setVisibility(View.GONE);


    }
}
