I have seen several posts (which for some reason I cannot reply to) that complain that there list item text is invisible when inside an AlertDialog unless they select it. I ran into this problem and wanted to post my solution.
If you use AlertDialog.Builder.setItems with a simple string array, then the Builder will create a ListView for you using R.layout.select_dialog_item resource. This creates working dialogs with visible text. The problem is when you try to use your own layout resource (perhaps to get a two line list item layout) with your own adapter with AlertDialog.Builder.setAdatper. You might try to use android.R.layout.simple_list_item_2 like I did. This causes the invisible text problem. The actual problem is simply a text color issue. android.R.layout.simple_list_item_2 uses white for the text color which is the same color as the background of an AlertDialog, causing a white on white situation making the text invisible. The R.layout.select_dialog_item layout resource used by AlertDialog.Builder by default when using setItems specifies a text color of android:textColor="@android:color/ primary_text_light_disable_only" which usually maps to black making the text visible. Therefore, to fix this problem, you need to get your text color to be what AlertDialog would normally choose by default. What I did was to copy the android.R.layout.simple_list_item_2 source code xml file to my own project so that I could edit it. I added the setting of the textColor with: android:textColor="?android:attr/textColorPrimaryInverseDisableOnly" I first tried using @android:color/primary_text_light_disable_only, but that would not compile because it is not public to app developers. I scanne the android source and discovered that ? android:attr/textColorPrimaryInverseDisableOnly maps to the exact same thing as @android:color/primary_text_light_disable_only, so it works great! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
