![]() Then, there is not enough width in the Parent, and thus one or more Buttons' text gets truncated. Problem 2: The ButtonBarSkin pref width computation ignores insets: putePrefWidth(double,double,double,double,double) ignores the insets values, instead using only ButtonBar's child HBox's minX and prefWidth. STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : Thus, if the developer has set any padding in the ButtonBar, then ButtonBarSkin computes a pref width that is too narrow. Run the executable test case application. Use case When using AlertDialog, there's no option of alignment to the actions passed. ![]() Observe that the Stage initializes at the initial pref width of the VBox, which is the pref width of its widest child, which later truncates the longest Button text after the ButtonBarSkin sets the uniform pref button widths. including launching an app or activity, scanning a barcode. Usually the community sugests to move your actions to the content parameter, but in this case your action. ButtonBar-specific parameters are used to specify attributes that apply to the entire. Observe that the pref widths of the ButtonBars are equal, despite the padding in the otherwise duplicate second ButtonBar. Stretch the width of the Stage until it reaches the pref width of the ButtonBars. Observe that the ButtonBar with padding still truncates the longest text. The ButtonBar without padding does not truncate the longest text, because it computes a correct pref width.īuttonBar Button text should not be truncated if the ButtonBar is laid out at its initial preferred width.īuttonBar Button text should not be truncated if the ButtonBar has padding and the ButtonBar is laid out at its final preferred width. Public class ButtonBarTruncatedTextExample extends Application to work around the * An example of truncated text in Buttons in ButtonBars. This allowed me to customize my AlertDialog buttons and layout.* superclass implementation's omission of the insets (if any) from its computation. ![]() So the conclusion that alert dialog buttons do not obey the Widget.Button is not yet proven from my point of view.Ĭonsolidated conclusion: The abilities to style alert dialogs independently of other widgets is limited in Android but getting more powerful as new versions improve in this respect. I don't have the resources to validate MrSnowflake's conclusion that it's impossible to style alert dialog buttons in XML, but unless we're facing one of those somewhat nasty aspects of Android where a feature is really missing, I find it unlikely.Īs a matter of fact, what's missing in the question is the most relevant part in this respect, namely I can't figure out exactly when this was introduced but it hasn't been Android 2.2 and Eclipse will tell you anyway. the alert dialog style has been around for quite some time but is limited to providing (background) drawables for "fullDark", "topDark" etc.Ĭustomizing the alert dialog theme opens a method to provide attributes such as windowBackground, windowTitleStyle and such, but as stated before, you need an Android version which supports the alertDialogThem attribute/item for themes. This is how the markup should look like not all Android versions support all features. In the question's markup, the will do nothing except creating the illusion that you're customizing the alert dialog theme when you're really only customizing the alert dialog style. But the markup used in the question suggests that it does.) (It may or may not be the case that such inconsistent Android versions exist, I don't know for sure. So even if is available on your Andoid platform, you still can't utilize its expressional power by hooking a cusomized version back into your own theme unless your Android platform supports an android:alertDialogTheme attribute/item for themes. There is something wrong with the markup in Steve Haley's question, and it is mixing up alertDialogStyle and alertDialogTheme, most likely because of the fact that alertDialogTheme was introduced long after alertDialogStyle was around. Given that MrSnowflake's reasoning is inaccurate, I'm taking the freedom to provide another answer. (Some other items were deleted for clarity, but they only relate to the title bar.) ideas? myTheme is applied to the whole via the manifest. What I've got below works for changing the backgrounds, but doesn't do anything with the buttons. ![]() Does anyone know how to override the default style for AlertDialog buttons? I've looked through the Android source for themes and styles and experimented with different things but I haven't been able to find a way that works.
