Android中強大的Dialog

Android中經常會使用到Dialog（彈出框效果），而且功能非常強大，可以類比出N種彈出框效果。：

下面將通過一個小執行個體，來像大家展示Android中功能強大的Dialog。代碼都寫了詳細的注釋，讀者不妨試著手動去敲。

當然，由於時間的關係，還有個別功能沒有完成，先有的幾個展示效果中也可能有bug，代碼也有很多需要最佳化的地方。望大家熱心指出。

下面是代碼（有點長哦）：

布局檔案部分，比較簡單：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    ><TextView      android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="@string/hello"    />    <Button    android:id="@+id/btnConfim"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="確定/取消"    />     <Button    android:id="@+id/btnMore"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="多個訊息提示"    />     <Button    android:id="@+id/BtnList"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="列表框"    />     <Button    android:id="@+id/BtnProgressbar"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="進度條框"    />     <Button    android:id="@+id/btnRidio"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="單選框"    />     <Button    android:id="@+id/btnCheck"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="多選框"    />     <Button    android:id="@+id/btnCustom"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="自訂布局"    />      <Button    android:id="@+id/btnRead"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="讀取進度框"    /></LinearLayout>
