This code snippet should help explain the three different buttons you can use:

<pre><code> alertDialog = new AlertDialog.Builder(this).create();

 alertDialog.setTitle("Dialog Button");

 alertDialog.setMessage("This is a three-button dialog!");

 alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "Button 1 Text", new DialogInterface.OnClickListener() {

 public void onClick(DialogInterface dialog, int id) {

 //...

 } }); 

 alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, "Button 2 Text", new DialogInterface.OnClickListener() {

 public void onClick(DialogInterface dialog, int id) {

 //...

 }}); 

 alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "Button 3 Text", new DialogInterface.OnClickListener() {

 public void onClick(DialogInterface dialog, int id) {

 //...

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

blocks|key|824308|text|创建对话框时，将类似以下内容添加到构建器中：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|824309|builder+=+new+AlertDialog.Builder(context);
builder.setTitle("Test");
builder.setIcon(R.drawable.icon);
builder.setMessage("test");

++++++++{
++++++++++++public+void+onClick(DialogInterface+dialog,+int+id)

++++++++new+DialogInterface.OnClickListener()
++++++++{
++++++++++++public+void+onClick(DialogInterface+dialog,+int+id)

When you are creating the dialog, add something like this to the builder:

<pre><code>builder = new AlertDialog.Builder(context);
builder.setTitle("Test");
builder.setIcon(R.drawable.icon);
builder.setMessage("test");
builder.setPositiveButton("Call Now",
 new DialogInterface.OnClickListener()
 {
 public void onClick(DialogInterface dialog, int id)
 {
 dialog.cancel();
 }
 });

builder.setNeutralButton("Setup",
 new DialogInterface.OnClickListener()
 {
 public void onClick(DialogInterface dialog, int id)
 {
 context.startActivity(new Intent(context, Setup.class));
 //dialog.cancel();
 }
 });

builder.setNegativeButton("Exit",
 new DialogInterface.OnClickListener()
 {
 public void onClick(DialogInterface dialog, int id)
 {
 dialog.cancel();
 }
 });
builder.create().show();
</code></pre>

The API says that the Alert Dialog can have one, two or three buttons, but the SDK only allows for a positive and negative button. How then can I add a third button?

How can I add a third button to an Android Alert Dialog?

API说警报对话框可以有一个、两个或三个按钮，但SDK只允许有一个肯定和否定按钮。那么我怎么才能添加第三个按钮呢？
