我如何将第三个按钮添加到Android Alert Dialog? (3)

该API说,警报对话框可以有一个,两个或三个按钮,但是SDK只允许一个正面和负面的按钮。 那么我怎样才能添加第三个按钮?


在创建对话框时,将这样的内容添加到构建器中:

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();

添加任何数量的不带xml的按钮:

    AlertDialog.Builder builder = new AlertDialog.Builder(context);
    builder.setTitle("Title");
    builder.setItems(new CharSequence[]
            {"button 1", "button 2", "button 3", "button 4"},
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    // The 'which' argument contains the index position
                    // of the selected item
                    switch (which) {
                        case 0:
                            Toast.makeText(context, "clicked 1", 0).show();
                            break;
                        case 1:
                            Toast.makeText(context, "clicked 2", 0).show();
                            break;
                        case 2:
                            Toast.makeText(context, "clicked 3", 0).show();
                            break;
                        case 3:
                            Toast.makeText(context, "clicked 4", 0).show();
                            break;
                    }
                }
            });
    builder.create().show();

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                    this);

            // set title
            alertDialogBuilder.setTitle("To Do List");

            // set dialog message
            alertDialogBuilder
                    .setMessage("What do you want?")
                    .setCancelable(false)
                    .setPositiveButton("Delete All", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            // if this button is clicked, close
                            // current activity




                            dialog.cancel();


                        }
                    }).setNeutralButton("Delete", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    // if this button is clicked, close
                    // current activity




                    dialog.cancel();

                }
            })
                    .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            // if this button is clicked, just close
                            // the dialog box and do nothing

                            dialog.cancel();
                        }
                    });

            // create alert dialog
            AlertDialog alertDialog = alertDialogBuilder.create();

            // show it
            alertDialog.show();
