弹出一个消息框

                        new AlertDialog.Builder(this)   .setTitle("确认")  .setMessage("kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk")  .setPositiveButton("是", null)   .show();

带确认和取消按钮的对话框

<span style="white-space:pre"></span>new AlertDialog.Builder(self) <span style="white-space:pre"></span>.setTitle("确认")<span style="white-space:pre"></span>.setMessage("确定吗？")<span style="white-space:pre"></span>.setPositiveButton("是", null)<span style="white-space:pre"></span>.setNegativeButton("否", null)<span style="white-space:pre"></span>.show();

注意到，这里有两个null参数，这里要放的其实是这两个按钮点击的监听程序，由于我们这里不需要监听这些动作，所以传入null值简单忽略掉，但是实际开发的时候一般都是需要传入监听器的，用来响应用户的操作。

一个可以输入文本的对话框

<span style="font-size:18px;"><span style="white-space:pre"></span>new AlertDialog.Builder(self)<span style="white-space:pre"></span>.setTitle("请输入")<span style="white-space:pre"></span>.setIcon(android.R.drawable.ic_dialog_info)<span style="white-space:pre"></span>.setView(new EditText(self))<span style="white-space:pre"></span>.setPositiveButton("确定", null)<span style="white-space:pre"></span>.setNegativeButton("取消", null)<span style="white-space:pre"></span>.show();</span>

单选框与多选框

<span style="font-size:18px;"> <span style="white-space:pre"></span>new AlertDialog.Builder(self)<span style="white-space:pre"></span>.setTitle("请选择")<span style="white-space:pre"></span>.setIcon(android.R.drawable.ic_dialog_info)                <span style="white-space:pre"></span>.setSingleChoiceItems(new String[] {"选项1","选项2","选项3","选项4"}, 0,  <span style="white-space:pre"></span> new DialogInterface.OnClickListener() {              <span style="white-space:pre"></span>   public void onClick(DialogInterface dialog, int which) {   <span style="white-space:pre"></span>     dialog.dismiss();   <span style="white-space:pre"></span>  }<span style="white-space:pre"></span>  }<span style="white-space:pre"></span>)<span style="white-space:pre"></span>.setNegativeButton("取消", null)<span style="white-space:pre"></span>.show();</span><span style="font-size:24px;"></span>

<span style="font-size:18px;"><span style="white-space:pre"></span>new AlertDialog.Builder(self)<span style="white-space:pre"></span>.setTitle("多选框")<span style="white-space:pre"></span>.setMultiChoiceItems(new String[] {"选项1","选项2","选项3","选项4"}, null, null)<span style="white-space:pre"></span>.setPositiveButton("确定", null)                <span style="white-space:pre"></span>.setNegativeButton("取消", null)<span style="white-space:pre"></span>.show();</span>

列表对话框

<span style="white-space:pre"></span>new AlertDialog.Builder(self)<span style="white-space:pre"></span>.setTitle("列表框")<span style="white-space:pre"></span>.setItems(new String[] {"列表项1","列表项2","列表项3"}, null)<span style="white-space:pre"></span>.setNegativeButton("确定", null)<span style="white-space:pre"></span>.show()

图片框

ImageView img = new ImageView(self);img.setImageResource(R.drawable.icon);new AlertDialog.Builder(self).setTitle("图片框").setView(img).setPositiveButton("确定", null).show();
