<resources> <style name="dialog" parent="@android:style/Theme.Dialog"> <item name="android:windowFrame"> <item name="android:windowIsFloating">true <item name="android:windowIsTranslucent">false <item name="android:windowNoTitle">true <item name="android:background">@android:color/black <item name="android:windowBackground">@null <item name="android:backgroundDimEnabled">false </style> </resources>
使用样式文件,在values 目录下新建styles.xml文件,编写如上代码:?
=================================
?
调用时,使用AlerDialog的接口类,Dialog 接口编写如下代码:
?
?
Dialog dialog = new Dialog(SetActivity.this, R.style.dialog); dialog.setContentView(R.layout.test); dialog.show();
?
下面我们查看一下Dialog的源码文件,里面的构造函数为如下:
?
public Dialog(Context context, int theme) { mContext = new ContextThemeWrapper( context, theme == 0 ? com.android.internal.R.style.Theme_Dialog : theme); mWindowManager = (WindowManager)context.getSystemService("window"); Window w = PolicyManager.makeNewWindow(mContext); mWindow = w; w.setCallback(this); w.setWindowManager(mWindowManager, null, null); w.setGravity(Gravity.CENTER); mUiThread = Thread.currentThread(); mDismissCancelHandler = new DismissCancelHandler(this); }
