问题 The problem Suppose you have a view inside a layout view, and you wish that each touching event on the layout would affect the view's background selector. for example, when you touch the layout , the selector of the view will choose the state_pressed state. What I've tried I've read about duplicateParentState and addStatesFromChildren , but I think it's the opposite of what I'm searching for. I've also tried to use splitMotionEvents, but it didn't help.

问题 The reason I need to do this programmatically is that the text color is downloaded and not pre defined in the xml. I read this Replace selector images programmatically I only need to know from StateListDrawable states = new StateListDrawable(); states.addState(new int[] {android.R.attr.state_pressed}, getResources().getDrawable(R.drawable.pressed)); how turn into states.addState(new int[] {android.R.attr.state_pressed},**theMethodImLookingFor**("#e3bb87")); forget about getResources()

问题 I have a row of buttons and i am setting their selectors for background and text programatically. The reason i want to do this programmatically is because, I have a set of themes the user can choose from and depending upon the theme selected, i want to change the selector for the button. For example, if the user selects a blue theme, when loaded, the background of the button is blue and text colour is white. When he presses the button, the background changes to white and the text colour
