Android Dialog详解及实例代码

 android dialog详解及实例代码

概述：

android开发中最常用的就是dialog类，除了自定义dialog布局，最多的就是用在弹出对话框、进度条、输入框、单选、复选框。

1、选择对话框：

alertdialog.builder dialog = new alertdialog.builder(this); 
dialog.settitle("选择对话框"); 
dialog.setmessage("请选择确认或取消"); 
dialog.setcancelable(false); //设置按下返回键不能消失 
dialog.setpositivebutton("确认", new dialoginterface.onclicklistener() { 
  @override 
  public void onclick(dialoginterface dialog, int which) { 
    toast.maketext(mainactivity.this, "您选择了确认", toast.length_long).show(); 
      } 
    }); 
    dialog.setnegativebutton("取消", new dialoginterface.onclicklistener() { 
      @override 
      public void onclick(dialoginterface dialog, int which) { 
        toast.maketext(mainactivity.this, "您选择了取消", toast.length_long).show(); 
      } 
    }); 
dialog.show();//显示弹出窗口 

2、进度条

progressdialog progressdialog = new progressdialog(this); 
progressdialog.settitle("显示进度条"); 
progressdialog.setmessage("加载中..."); 
progressdialog.setcancelable(true); 
progressdialog.show(); 

3、弹出输入框

alertdialog.builder builder = new alertdialog.builder(this); 
builder.settitle("弹出输入框"); 
builder.setmessage("输入内容"); 
final edittext edittext = new edittext(this); 
builder.setview(edittext); 
builder.setpositivebutton("确定", new dialoginterface.onclicklistener() { 
      @override 
  public void onclick(dialoginterface dialog, int which) { 
    toast.maketext(mainactivity.this, "您输入了" + edittext.gettext().tostring(), toast.length_short).show(); 
      } 
  }); 
builder.setnegativebutton("取消", null); 
builder.show(); 

4、弹出单选框

final alertdialog.builder builder = new alertdialog.builder(this); 
builder.settitle("弹出单选框"); 
final string[] choice = new string[]{"java", "c++", "php"}; 
builder.setsinglechoiceitems(choice, 0, 
  new dialoginterface.onclicklistener() { 
    @override 
    public void onclick(dialoginterface dialog, int which) { 
      toast.maketext(mainactivity.this, "您选择了" + choice[which], toast.length_long).show(); 
      dialog.dismiss(); // 让窗口消失 
    } 
  }); 
builder.create().show(); 

5、弹出复选框

final alertdialog.builder builder = new alertdialog.builder(this); 
builder.settitle("弹出多选框"); 
final string[] choice = new string[]{"android", "ios", "windos phone"}; // 选择项 
final boolean[] ischeck = new boolean[choice.length]; // 是否被选中 
builder.setmultichoiceitems(choice, null, 
  new dialoginterface.onmultichoiceclicklistener() { 
    @override 
    public void onclick(dialoginterface dialog, int which, boolean ischecked) { 
      if (ischecked == true) 
        ischeck[which] = true; 
      else if(ischecked == false) 
        ischeck[which] = false; 
     } 
  }); 
builder.setnegativebutton("取消", null); 
builder.setpositivebutton("确定", new dialoginterface.onclicklistener() { 
  @override 
  public void onclick(dialoginterface dialog, int which) { 
    string isselected = "您选择了"; 
    for (int i = 0; i < choice.length; i++) { 
      if (ischeck[i] == true) { 
        isselected += choice[i]+","; // 将选择的内容加上 
      } 
    } 
    toast.maketext(mainactivity.this, isselected, toast.length_long).show(); 
   } 
}); 
builder.create(); 
builder.show(); 

6、自定义布局的dialog

alertdialog.builder builder = new alertdialog.builder(this); 
 final alertdialog dialog = builder.create(); 
 view view = view.inflate(this, r.layout.personal_modifyhead_dialog, null); 
 dialog.setview(view, 0, 0, 0, 0);// 设置边距为0,保证在2.x的版本上运行没问题 
 dialog.show(); 
 
 autorelativelayout rl_photograph = (autorelativelayout) view.findviewbyid(r.id.rl_photograph); 
 rl_photograph.setonclicklistener(new view.onclicklistener() { 
   @override 
   public void onclick(view v) { 
     presenter.modiftheadfromphotograph(); 
     dialog.dismiss(); 
   } 
 }); 
 
 autorelativelayout rl_album = (autorelativelayout) view.findviewbyid(r.id.rl_album); 
 rl_album.setonclicklistener(new view.onclicklistener() { 
   @override 
   public void onclick(view v) { 
     presenter.modifyheadfromalbum(); 
     dialog.dismiss(); 
   } 
 }); 

上面就是日常开发中常用的一些，在此记录，以便日后查询。
