1.通过H5页面的超链接尾部信息不同进行跳转(类似于URL拦截器)
例如:控件x的href="http://www.example.com/?menu_id=1",
在代码中添加webview
import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.util.Log; import android.webkit.WebView; import android.webkit.WebViewClient; import android.widget.Toast; /** * Author:JsonLu * DateTime:2015/8/31 17:52 * Email:luxd@i_link.cc */ public class SecoundActivity extends Activity{ private WebView mWebView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mWebView = (WebView)findViewById(R.id.webview); String url = "http://jcut.sinaapp.com/androidjs/second.html?menu_id=1"; this.mWebView.loadUrl(url); mWebView.setWebViewClient(new MyWebViewClient()); } private class MyWebViewClient extends WebViewClient { @Override public boolean shouldOverrideUrlLoading(WebView view, String url) { Log.d("URL",url); Intent it = new Intent(); if(url.endsWith("?menu_id=1")){ it.setClass(SecoundActivity.this, MainActivity.class); startActivity(it); }else{ Toast.makeText(SecoundActivity.this,"时间："+System.currentTimeMillis(),Toast .LENGTH_LONG).show(); } return true; } } }
2.通过js调用本地类的方法
import android.annotation.TargetApi; import android.app.Activity; import android.content.Intent; import android.os.Build; import android.os.Bundle; import android.webkit.JavascriptInterface; import android.webkit.WebView; import android.widget.Toast; /** * Author:JsonLu * DateTime:2015/8/31 17:52 * Email:luxd@i_link.cc */ public class MainActivity extends Activity { private WebView mWebView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); this.initView(); } @TargetApi(Build.VERSION_CODES.ECLAIR_MR1) private void initView() { this.mWebView = (WebView) this.findViewById(R.id.webview); //可以执行javascript this.mWebView.getSettings().setJavaScriptEnabled(true); String url = "http://jcut.sinaapp.com/androidjs/"; this.mWebView.loadUrl(url); //android添加javascript代码，让H5页面能够调用，第二个参数对应的是H5的 this.mWebView.addJavascriptInterface(new PayJavaScriptInterface(), "js"); } private class PayJavaScriptInterface { @JavascriptInterface public void jumpActivity(int param) { if (param == 1) { Intent it = new Intent(); it.setClass(MainActivity.this, SecoundActivity.class); startActivity(it); } else { Toast.makeText(MainActivity.this, "时间：" + System.currentTimeMillis(), Toast.LENGTH_SHORT) .show(); } } } }
