代码如下：

自定义Dialog：

public class SelectDialog extends AlertDialog\{    
public SelectDialog(Context context, int theme) \{     super(context, theme); \}    
public SelectDialog(Context context) \{     super(context); \}    
@Override   
protected void onCreate(Bundle savedInstanceState) \{     super.onCreate(savedInstanceState);     setContentView(R.layout.slt\_cnt\_type); \} \}

2、布局文件slt\_cnt\_type.xml代码

<?xml version="1.0" encoding="utf-8"?> <LinearLayout   
  xmlns:android="http://schemas.android.com/apk/res/android"   android:orientation="vertical"   
  android:padding="10dp" android:layout\_width="115dp" android:layout\_height="wrap\_content" android:background="@color/blue">   
    <Button android:layout\_height="wrap\_content" android:background="\#00000000" android:layout\_width="fill\_parent" android:text="全部联系人" android:paddingTop="5dp" android:paddingBottom="5dp" android:paddingLeft="10dp" android:gravity="left|center\_vertical" android:id="@+id/btnSltCntAll"></Button>   
    <Button android:layout\_height="wrap\_content" android:background="\#00000000" style="@drawable/greenhand\_button" android:text="咕咚用户" android:gravity="left|center\_vertical" android:paddingBottom="5dp" android:paddingTop="5dp" android:paddingLeft="10dp" android:paddingRight="10dp" android:layout\_width="fill\_parent" android:id="@+id/btnSltGudongUser"></Button>   
    <Button style="@drawable/greenhand\_button" android:background="\#00000000" android:layout\_height="wrap\_content" android:layout\_width="fill\_parent" android:text="推荐用户" android:gravity="left|center\_vertical" android:paddingTop="5dp" android:paddingBottom="5dp" android:paddingLeft="10dp" android:id="@+id/btnSltRecommend"></Button> </LinearLayout>

3、颜色color.xml代码

<?xml version="1.0" encoding="utf-8"?> <resources>   
  <color name="transparent">\#00000000</color> </resources>    
  
  
4、样式style.xml代码

<?xml version="1.0" encoding="utf-8"?> <resources>   
    <style name="dialog" parent="@android:style/Theme.Dialog">

<item name="android:windowIsTranslucent">false</item>

<item name="android:windowNoTitle">true</item>   
        <item name="android:windowBackground">@color/transparent</item>

<item name="android:backgroundDimEnabled">false</item>     </style> </resources>

4、显示Dialog

SelectDialog selectDialog = new SelectDialog(this,R.style.dialog);//创建Dialog并设置样式主题

Window win = selectDialog.getWindow(); LayoutParams params = new LayoutParams();

params.x = -80;//设置x坐标 params.y = -60;//设置y坐标

win.setAttributes(params);   
selectDialog.setCanceledOnTouchOutside(true);//设置点击Dialog外部任意区域关闭

Dialog selectDialog.show();
