android弹出框

不得不说，android自带的弹出框真心丑，而且还不好用，接下来介绍几种自定义的弹出框，并且源码防到附件里面。

Android的弹框按照我的理解，至少有两种，一种是自己写个弹框，继承Dialog借口，一种是写一个非全屏的Activity，样式上来讲，应该是后者更好看一些吧。
上面直接上代码:
dialog_normal_layout.xml

使用 :

CustomDialog.Builder builder = new CustomDialog.Builder(this);
		builder.setMessage("这个就是自定义的提示框");
		builder.setTitle("提示");
		builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
			public void onClick(DialogInterface dialog, int which) {
				dialog.dismiss();
				//设置你的操作事项
			}
		});

		builder.setNegativeButton("取消",
				new android.content.DialogInterface.OnClickListener() {
					public void onClick(DialogInterface dialog, int which) {
						dialog.dismiss();
					}
				});

		builder.create().show();
