WebView 的button多操作

第一次写博客，不会写呢，我能力不大，望各位前辈多指教！

(不知道怎么上图，就不上图了)

                            APP  2012-11-16

package gg.demo.web;


import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.webkit.WebView;
import android.webkit.WebViewClient;


/**不知道这个算不算是？？？

public class MainActivity extends Activity implements OnClickListener {


MyWeb my;


public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);


my = (MyWeb) this.findViewById(R.id.webView);


this.findViewById(R.id.one).setOnClickListener(this);
this.findViewById(R.id.two).setOnClickListener(this);
this.findViewById(R.id.three).setOnClickListener(this);


my.setWebViewClient(new WebViewClient() {


public boolean shouldOverrideUrlLoading(WebView view, String url) {
super.shouldOverrideUrlLoading(view, url);

view.loadUrl(url);


return true;
}


});
}


String tag = "System.out";


String str1 = "http://www.baidu.com";
String str2 = "http://www.163.com";
String str3 = "http://www.csdn.net";


public void onClick(View v) {
switch (v.getId()) {
case R.id.one:
my.load(MainActivity.this, str1);


break;
case R.id.two:


my.load(MainActivity.this, str2);


break;
case R.id.three:


my.load(MainActivity.this, str2);


break;


}
}
}

重写webView.

package gg.demo.web;


import java.util.ArrayList;


import android.annotation.SuppressLint;
import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.webkit.WebView;


@SuppressLint("NewApi")
public class MyWeb extends WebView {


private ArrayList<WebView> webs = new ArrayList<WebView>();


private MyWeb web = this;


public MyWeb(Context context) {
super(context);
}


public MyWeb(Context context, AttributeSet attrs) {
super(context, attrs);
}


public MyWeb(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}


public MyWeb(Context context, AttributeSet attrs, int defStyle,
boolean privateBrowsing) {
super(context, attrs, defStyle, privateBrowsing);
}


private int flag = 0;


public void load(Context context, String url) {
WebView w = this;
webs.add(w);
w.setTag(flag);
flag++;

w.loadUrl(url);
}


public void stop(View v) {
int i = Integer.parseInt(v.getTag().toString());
WebView webView = webs.get(i);
webView.stopLoading();
}


public void stopOthers(View v) {
int j = Integer.parseInt(v.getTag().toString());


for (int k = 0; k < webs.size(); k++) {
if (j != k) {
WebView we = webs.get(k);
we.stopLoading();
}
}
}


}
