1. 建立Dialog

dialog=new Dialog(context, R.style.SelectTimeTheme);

dialog.setContentView(R.layout.pop_select_time);
Window window = dialog.getWindow();

WindowManager manager = context.getWindowManager();
Display display = manager.getDefaultDisplay();

WindowManager.LayoutParams p = window.getAttributes();
p.width
 
=(int) (display.getWidth()*1);
p.height=(int) (display.getHeight()*0.3);
p.gravity= Gravity.BOTTOM;
window.setAttributes(p);
dialog.setFeatureDrawableAlpha(Window.FEATURE_OPTIONS_PANEL, 0);
window.setWindowAnimations(android.R.anim.fade_in);

3. 設定樣式 R.style.SelectTimeTheme

<style name=
 
"SelectTimeTheme" parent="android:Theme.Holo.Light">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowCloseOnTouchOutside"
 
>true</item>

</style>
