If the URL depends directly on the ID, then try this:

<pre><code>public void webClick(View v) 
{
 Intent intent = new Intent(this, Webview.class);
 intent.putExtra("weblink","file:///android_asset/chapter/chapter" + v.getId() + ".html");
 startActivity(intent);
}
</code></pre>

EDITED

In the case you URL doesn't depend directly on the ID, then try mapping button IDs with URLS, like this:

<pre><code>Map&lt;Integer, String&gt; urls = new HashMap();

urls.put(R.id.button1, "file:///android_asset/chapter/chapter100.html");
// ... 1 to 100 ...
</code></pre>

and modify the above code like this:

<pre><code>public void webClick(View v) 
{
 Intent intent = new Intent(this, Webview.class);
 intent.putExtra("weblink", urls.get(v.getId()));
 startActivity(intent);
}
</code></pre>

EDITED #2

If in the label of your buttons you already have the URL, a sugestion (not mine but made by @pad) would be to use it to calculate the URL this way:

<pre><code>public void webClick(View v) 
{
 Intent intent = new Intent(this, Webview.class);
 intent.putExtra("weblink", "file:///android_asset/chapter/chapter" + v.getText().replaceAll("Chapter ","") + ".html"); // Assuming your text is like "Chapter 50"
 startActivity(intent);
}
</code></pre>

For more number of buttons in your case, Dynamically create button in a loop and assign onclick event like..

Create one <code>LinearLayout</code> in your xml file.

Now add this all buttons in that LinearLayout like..

<pre><code>String[] urls={url1,url2.....url100}; // here write your all URLs
Button button[]= new Button[100];
LinearLayout mainlinear=(LinearLayout) findViewById(R.id.main_layer);
for (int i = 0; i &lt; 100; i++) {
 button[i] = new Button(this);
 button[i].setText(i);
 button[i].setTag(i+":"+URL); // URL = What you need to pass when button is click
 button[i].setOnClickListener(new OnClickListener() {
 @Override
 public void onClick(View v) {

 TextView selected = (TextView) v;
 String tag = selected.getTag().toString();

 //Here you need to write your code when button is pressed.

Intent intent = new Intent(this, Webview.class);
 intent2.putExtra("weblink",urls[i]);
 startActivity(intent2);
 }

 }
 mainlinear.addView(button[i]);
</code></pre>

blocks|key|1347692|text|您可能想要使用ListView。如果您想要有按钮，那么使用ListView，它在每个项目的布局中都有一个按钮。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1347693|然后，设置一个onItemClickListener。您将获得该按钮的位置(第一个按钮的位置为0，第二个按钮的位置为1，依此类推)。然后写一个链接：|1347694|String+link=+"file:///android_asset/chapter/chapter"+%2B+(position+%2B1)+%2B+".html";|code-block|syntax|javascript|1347695|剩下的代码将是相同的(intent.putExtra("weblink",+link);)|offset|length|style|CODE|1347696|entityMap^0|0|0|0|B|X|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|R|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|S|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|T|8|@$K|U|L|V|M|N]]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

You might want to use a ListView. If you want to have buttons, then use a ListView, which has one button in each item's layout. 

Then, you setup a onItemClickListener. You get the position of that button (the first one has position 0, the second has position 1, etc.). Then compose a link:

<pre><code>String link= "file:///android_asset/chapter/chapter" + (position +1) + ".html";
</code></pre>

The rest of your code, would be the same (<code>intent.putExtra("weblink", link);</code>)

blocks|key|1491425|text|我的建议是在这种情况下使用ListView或GridView，并将文件名保存在ArrayList中。然后，您可以这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1491426|List<String>+urlList+=+new+ArrayList<String>();

urlList.add("file:///android_asset/chapter/chapter2.html");

++++++++++++++++++++intent.putExtra("weblink",+urlList.get(position));
++++++++++++++++++++startActivity(intent);

++++++++++++}
++++++++});|code-block|syntax|javascript|1491427|这将是一个很好的实现，因为您可以避免使用100个按钮和OnClickListeners来保存一些资源。|1491428|编辑:这段代码应该正在运行，只需将其放入onCreate()中进行一些测试即可。你所要做的就是在你的layout.xml中定义一个ListView，而不是像下面这样的100个按钮：|1491429|<?xml+version="1.0"+encoding="utf-8"?>++
<LinearLayout+xmlns:android="http://schemas.android.com/apk/res/android"++

++++<ListView+android:layout_width="match_parent"+++
++++++android:layout_height="match_parent"+++
++++++android:id="@%2Bid/listView">++
++++</ListView>++

</LinearLayout>|1491430|如果你真的想使用按钮，而不是遵循摩根的建议。|1491431|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|T|8|@]|9|@]|A|$]]|$1|K|3|L|5|D|7|U|8|@]|9|@]|A|$E|F]]|$1|M|3|N|5|6|7|V|8|@]|9|@]|A|$]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

My suggestion is to use a ListView or GridView for this case and save the file names in an ArrayList. Then you do something like this:

<pre><code>List&lt;String&gt; urlList = new ArrayList&lt;String&gt;();
urlList.add("file:///android_asset/chapter/chapter1.html");
urlList.add("file:///android_asset/chapter/chapter2.html");
// and so on

ListView listView = (ListView)findViewById(R.id.listView);
ArrayAdapter adapter = new ArrayAdapter(this, android.R.id.simple_list_item_1, urlList);
 listView.setOnItemClickListener(new OnItemClickListener() {

 @Override
 public void onItemClick(AdapterView&lt;?&gt; parent, View view,
 int position, long id) {

 Intent intent = new Intent(this, Webview.class);
 intent.putExtra("weblink", urlList.get(position));
 startActivity(intent);

 }
 });
</code></pre>

This would be a nice implementation because you would avoid using 100 Buttons and OnClickListeners to save some ressources.

Edit: This code should be running, just put it in onCreate() for some testing. All you have to do is to define a ListView in your layout.xml insteed of the 100 buttons like this:

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; 
&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 android:orientation="vertical" 
 android:layout_width="match_parent" 
 android:layout_height="match_parent"&gt; 

 &lt;ListView android:layout_width="match_parent" 
 android:layout_height="match_parent" 
 android:id="@+id/listView"&gt; 
 &lt;/ListView&gt; 

&lt;/LinearLayout&gt;
</code></pre>

If you really wanna use this with Buttons than follow morgano's suggestion.

I have 100 buttons in layout and <code>OnClick()</code> method for all of it.

If I use <code>switch</code> I need to do <code>case R.id.button1, ..., case R.id.button100</code> for all 100 buttons. How to shorten this code?

<pre><code>public void webClick(View v) 
{
 switch(v.getId())
 {
 case R.id.button1:
 Intent intent = new Intent(this, Webview.class);
 intent.putExtra("weblink","file:///android_asset/chapter/chapter1.html");
 startActivity(intent);
 break;

 case R.id.button2:
 Intent intent2 = new Intent(this, Webview.class);
 intent2.putExtra("weblink","file:///android_asset/chapter/chapter2.html");
 startActivity(intent2);
 break;

 // ...

 case R.id.button100:
 Intent intent100 = new Intent(this, Webview.class);
 intent100.putExtra("weblink","file:///android_asset/chapter/chapter100.html");
 startActivity(intent100);
 break;
 }
 }
</code></pre>
