前言：這個過程中遇到了兩個問題，都比較基礎，第一個問題是：系統無法識別圖片資源，不過還好，被我刪了之后就很好的運行了，第二個也是比較鬼畜的問題，錯把==符號變成了！=結果導致閃退缺不報錯！現在我們為什么要來這一個屬于自己的dialog，原因很簡單，安卓自帶的太丑了！！！而且局限性強，那么為了解決這個問題，分開view與邏輯，更方便的進行拓展下面我們需要用一個非常常見的設計模式builder！
buidler設計模式：一個比方——組裝電腦，一系列產品的電腦，可以有不同的配置，不同的cpu，不同的arm，一個電腦最后的模樣是取決于各個配件的組合，同樣的道理，我們在使用dialog的過程中也會有這樣那樣的需求，因此，1.為了更靈活的去運用dialog，實現更多樣化。2.為了易拓展，view與實現邏輯分開！等…
具體需要的類有三個，DialogViewhelper(輔助類存在)，AlertDialog,AerltController
下面簡單來介紹一下這三個類吧，先從AlertDialog介紹起，為什么從這個介紹起呢，因為如果你來寫，也會從這里寫起，主要思路是先用AlertDialog來講我們所所需要的，參數傳遞進來，當然它也是這個的入口，然后是AlertController這個用來傳遞參數，到最后，用DialogViewhelper進行最終的實現，當然如果你不想寫那個輔助類也行下面簡單來介紹一下這三個類吧，先從AlertDialog介紹起，為什么從這個介紹起呢，因為如果你來寫，也會從這里寫起，主要思路是先用AlertDialog來講我們所所需要的，參數傳遞進來，當然它也是這個的入口，然后是AlertController這個用來傳遞參數，到最后，用DialogViewhelper進行最終的實現，當然如果你不想寫那個輔助類也行
1，AerltDialog類：繼承了Dialog（值得注意的是這里繼承的只是Dialog而非AlertDialog），這里具體的一些思路是，構造函數出來，然后new一個AlertController出來然后，設置一些傳遞參數用的方法如：setText和getview這些，當然主要的還是builder里面的內容是直接仿安卓源碼的，將數據放入P中，然后進行傳遞！當然這里最好加上一個通過id去尋找的setContextView,同時值得注意的是，無論是文本還是事件不止只有一個，所以用SparseArray儲存起來！為什么要使用這個呢，很簡單在安卓源碼里頭，有一句英語表明了如果是鍵值對為int加值的這種，這個比hasmp更優越！
這里有想法的人最好去看看源碼！！

2.AlertContorller：
這個類里面我們是給了一系列參數了的，那么這個類是干什么的呢很簡單，傳過來的參數傳到vieqhelper里面進行實現，當然，在這個過程中，我們需要做一些優化，比如說，我們需要做，一些參數在值上默認，容錯等等，這些就不具體將了注視里面相當清楚了，
而我這里主要實現了什么東西呢？1.設置文本，2.設置監聽事件，3.配置全屏 從底部彈出，動畫等！！
