先看效果：

这是我做的一个拨号器强的面板，拨号的时候会查询手机中的联系人，显示在拨号面板上方，点击弹出透明对话框供选择。

这次重点是透明对话框。

先看对话框的theme，style文件：

[html] view plain copy

<?xmlversion="1.0"encoding="utf-8"?>
<resources>
<style
name="selectorDialog"
parent="@android:style/Theme.Dialog">
<itemname="android:windowFrame">@null</item>
<itemname="android:windowIsFloating">true</item>
<itemname="android:windowIsTranslucent">false</item>
<itemname="android:windowNoTitle">true</item>
<itemname="android:windowBackground">@drawable/selector_dialog_bg</item>
<itemname="android:backgroundDimEnabled">false</item>
<itemname="android:backgroundDimAmount">0.6</item>
</style>
</resources>

对话框背景@drawable/selector_dialog_bg：

[html] view plain copy

<?xmlversion="1.0"encoding="utf-8"?>
<shapexmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solidandroid:color="#333333"/>
<stroke
android:width="2dp"
android:color="#99CC33"/>
<padding
android:left="5dp"
android:top="5dp"
android:right="5dp"
android:bottom="5dp"/>
<cornersandroid:radius="8dp"/>
</shape>

然后是对话框的布局：

[html] view plain copy

<?xmlversion="1.0"encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ListView
android:id="@+id/selector_dialog_listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"
android:scrollbars="none"
android:dividerHeight="1.0dip"
android:divider="#C4C4C4"/>
</LinearLayout>

程序中：

[java] view plain copy

finalViewview=LayoutInflater.from(this).inflate(R.layout.selector_dialog,null);
selectorDialog=newDialog(DialerActivity.this,R.style.selectorDialog);
selectorDialog.setContentView(view);
finalBaseAdapteradapter=newSelectorAdapter(DialerActivity.this,selectorList);
ListViewlistView=(ListView)view.findViewById(R.id.selector_dialog_listview);
listView.setOnItemClickListener(newOnItemClickListener(){
@Override
publicvoidonItemClick(AdapterView<?>parent,Viewview,intposition,longid){
//对话框中事件处理
}
});
listView.setAdapter(adapter);
selectorDialog.show();
selectorDialog.setCanceledOnTouchOutside(true);
WindowManagerwindowManager=getWindowManager();
Displaydisplay=windowManager.getDefaultDisplay();
WindowManager.LayoutParamslp=selectorDialog.getWindow().getAttributes();
lp.width=(int)(display.getWidth()*0.9);
if(selectorList.size()>7){
lp.height=(int)(display.getHeight()*0.9);
}
lp.alpha=0.8f;
selectorDialog.getWindow().setAttributes(lp);

其实主要是通过WindowManager.LayoutParams给对话框设置属性。
