Android中强大的Dialog

Android中经常会使用到Dialog（弹出框效果），而且功能非常强大，可以模拟出N种弹出框效果。如图所示：

下面将通过一个小实例，来像大家展示Android中功能强大的Dialog。代码都写了详细的注释，读者不妨试着手动去敲。

当然，由于时间的关系，还有个别功能没有完成，先有的几个展示效果中也可能有bug，代码也有很多需要优化的地方。望大家热心指出。

下面是代码（有点长哦）：

   int mSingleChoiceID = -1;    ArrayList <Integer>MultiChoiceID = new ArrayList <Integer>();    private ProgressDialog mProgressDialog  = null;    private static final int MAX_PROGRESS = 100;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        /*START 设置那些按钮的点击监听对象*/        ButtonOnclikListen listen =new ButtonOnclikListen();        Button btnConfim =(Button)this.findViewById(R.id.btnConfim);        Button btnCheck =(Button)this.findViewById(R.id.btnCheck);

布局文件部分，比较简单：

<?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="确定/取消"    />     <Button    android:id="@+id/btnMore"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="多个消息提示"    />     <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="进度条框"    />     <Button    android:id="@+id/btnRidio"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="单选框"    />     <Button    android:id="@+id/btnCheck"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="多选框"    />     <Button    android:id="@+id/btnCustom"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="自定义布局"    />      <Button    android:id="@+id/btnRead"    android:layout_width="fill_parent"     android:layout_height="wrap_content"    android:text="读取进度框"    /></LinearLayout>
