Android dialog去除边框代码

 使用样式文件，在values 目录下新建styles.xml文件

Java代码：

1. <resources>
2. <style name="dialog" parent="@android:style/Theme.Dialog">
3. <item name="android:windowFrame">@null</item>
4. <item name="android:windowIsFloating">true</item>
5. <item name="android:windowIsTranslucent">false</item>
6. <item name="android:windowNoTitle">true</item>
7. <item name="android:background">@android:color/black</item>
8. <item name="android:windowBackground">@null</item>
9. <item name="android:backgroundDimEnabled">false</item>
10. </style>
11. </resources>

复制代码

                  调用时，使用AlerDialog的接口类

Java代码：

1. Dialog dialog =new Dialog(SetActivity.this, R.style.dialog);
2. dialog.setContentView(R.layout.test);
3. dialog.show();
8. public Dialog(Context context, int theme) {
9. mContext =new ContextThemeWrapper(context, theme ==0?com.android.internal.R.style.Theme_Dialog : theme);
11. mWindowManager = (WindowManager)context.getSystemService("window");
12. Window w = PolicyManager.makeNewWindow(mContext);
13. mWindow = w;
14. w.setCallback(this);
15. w.setWindowManager(mWindowManager, null, null);
16. w.setGravity(Gravity.CENTER);
17. mUiThread = Thread.currentThread();
18. mDismissCancelHandler =new DismissCancelHandler(this);
19. }
