安卓自定义超级提示框Dialog
源码下载地址：http://download.csdn.net/detail/haiyangzhisheng/9504180
话题来源：为新的项目添加原来的项目做的提示框时，要把原来项目的自定义Dialog复制过来，整理了一下，需要提示框时只需要复制Java类和一个布局文件和动画文件就行了
使用方式：
final AAMyAlertDialogmDialog = new AAMyAlertDialog(this);
mDialog.setTitle("我的提示");
mDialog.setMessage("提示内容");
mDialog.setPositiveButton("确定",new OnClickListener() {
@Override
public void onClick(Viewv) {
mDialog.dismiss();
}
});
mDialog.setNegativeButton("取消",new OnClickListener() {
@Override
public void onClick(Viewv) {
}
});
mDialog.setMidleButton("操作",new OnClickListener() {
@Override
public void onClick(Viewv) {
}
});
mDialog.show();
实现原理：
1、继承Dialog类
2、GradientDrawable实现圆角背景
3、StateListDrawable实现点击效果
4、在onAttachedToWindow方法中设置弹出框在手机中占比
5、Xml中定义AlphaAnimation、ScaleAnimation等动画类实现动画效果
实现代码解析：
