这是我的主要活动文件：
package com.example.androidtablayoutactivity;
import java.net.MalformedURLException;
import java.net.URL;
import android.app.TabActivity;
import android.content.Intent;
import android.os.Bundle;

public class AndroidTabLayoutActivity extends TabActivity {
/** Called when the activity is first created. */
TabHost tabHost;
TabSpec photospec;

TextView text;
Intent photosIntent ;
private int counter=0;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

go.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {

}
public void go(){
photospec = tabHost.newTabSpec("");
// setting Title and Icon for the Tab
URL url = null;
try {

}
if(counter==0){
photospec.setIndicator(url.getHost().replace("www."," ").replace(".com"," "));
photosIntent = new Intent(Intent.ACTION_VIEW);
photosIntent.setClass(this, PhotosActivity.class);
photosIntent.putExtra("URL1", text.getText().toString());
photospec.setContent(photosIntent);
tabHost.addTab(photospec);
}
else{

photospec.setIndicator(url.getHost().replace("www."," ").replace(".com"," "));
photosIntent = new Intent(Intent.ACTION_VIEW);
photosIntent.putExtra("URL1", text.getText().toString());
photosIntent.setClass(this, PhotosActivity.class);
photospec.setContent(photosIntent);
tabHost.addTab(photospec);
}
counter++;
}
}
这是我制作浏览器进程的其他活动
package com.example.androidtablayoutactivity;
import com.example.androidtablayoutactivity.SongsActivity.web;
import android.app.Activity;
import android.app.TabActivity;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.Button;
import android.widget.TabHost;
import android.widget.TextView;
import android.widget.TabHost.TabSpec;
public class PhotosActivity extends Activity{
WebView web;
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.photos_layout);
web=(WebView)findViewById(R.id.web);
web.setWebViewClient(new web());
web.getSettings().setJavaScriptEnabled(true);
Bundle extras = getIntent().getExtras();
if(extras==null){
web.loadUrl("");
}
else
{
web.loadUrl(extras.getString("URL1"));
}
}
public class web extends WebViewClient{
@Override
public boolean shouldOverrideUrlLoading(WebView webview,String url){
webview.loadUrl(url);
return true;
}
}
}
这是它的布局文件
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<WebView
android:id="@+id/web"
android:layout_width="385dp"
android:layout_height="fill_parent" />
</LinearLayout>
当我第一次单击 go 按钮时，我正在使用 go 和新选项卡按钮在 android 中使用浏览器 mybrowser 将转到我想要的 url 但是当我再次单击时，我的地址不会改变
