話題來源：爲新的項目添加原來的項目做的提示框時，要把原來項目的自定義Dialog複製過來，整理了一下，需要提示框時只需要複製Java類和一個佈局文件和動畫文件就行了
使用方式：
final AAMyAlertDialogmDialog = new AAMyAlertDialog(this);
mDialog.setTitle("我的提示");
mDialog.setMessage("提示內容");
mDialog.setPositiveButton("確定",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();
實現原理：
1、繼承Dialog類
2、GradientDrawable實現圓角背景
3、StateListDrawable實現點擊效果
4、在onAttachedToWindow方法中設置彈出框在手機中佔比
5、Xml中定義AlphaAnimation、ScaleAnimation等動畫類實現動畫效果
