浅析Android开发之使用alertdialog的详解

AlertDialog.Builder builder = new AlertDialog.Builder(this);
   builder.setTitle("确认对话框");
   builder.setIcon(R.drawable.icon_72);
   builder.setMessage("这里是对话框内容");
   builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface arg0, int arg1) {
     // TODO Auto-generated method stub
     Toast.makeText(AlertDialog_text.this, "点击了确定按钮", 1).show();
    }
   });
   AlertDialog dialog = builder.create();
   dialog.show(); //显示、

final String[] items = new String[]{"语文","数学","英语","物理","化学"}; //列表项
   Builder alertdialog = new AlertDialog.Builder(this); 
   alertdialog.setTitle("你喜欢的课程").setItems(items, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
     // TODO Auto-generated method stub
     Toast.makeText(AlertDialog_lianxi.this, items[which], Toast.LENGTH_SHORT).show();
    }
   });
   alertdialog.create().show();     //创建显示列表

final String[] items_fruit = new String[]{"苹果","香蕉","橘子","西瓜","梨"};
   Builder alerdialog = new AlertDialog.Builder(this);
   //设置列表标题
   alerdialog.setTitle("你喜欢的水果");
   //设置单选列表
   alerdialog.setSingleChoiceItems(items_fruit, 0, new DialogInterface.OnClickListener() {
    @Override
    public void onClick(DialogInterface dialog, int which) {
     // TODO Auto-generated method stub
     Toast.makeText(AlertDialog_lianxi.this, items_fruit[which], Toast.LENGTH_SHORT).show();
    }
   });
   //设置取消按钮并且设置响应事件

    public void onClick(DialogInterface dialog, int which) {
     // TODO Auto-generated method stub
     //取消按钮响应事件
    }
