WebView简单使用

public class MainActivity extends Activity {

    WebView webView;

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

        webView = (WebView)findViewById(R.id.webview);

        // js可用
        webView.getSettings().setJavaScriptEnabled(true);
        // 在当前webview中打开,不在浏览器中打开连接
        webView.setWebViewClient(new WebViewClient(){
            @Override
            public boolean shouldOverrideUrlLoading(WebView view, WebResourceRequest request) {
                webView.loadUrl(request.getUrl().toString());
                return true;
            }
        });
        webView.loadUrl("http://www.baidu.com");
    }
}
