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:[email protected]_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:[email protected]_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();
}
}
}
}
