Android AlertDialog去除白色边框代码
使用样式文件，在values 目录下新建styles.xml文件，编写如下代码：
< resources> < style name="dialog" parent="@android:style/Theme.Dialog"> < item name="android:windowFrame">@null < 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>
Dialog dialog = new Dialog(SetActivity.this, R.style.dialog); dialog.setContentView(R.layout.test); dialog.show();
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); }
