Answer 1

你可以这样做：

SharedPreferences sharedPref = getSharedPreferences("COLOR", MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
// Only if you know it is a color
ColorDrawable buttonColor = (ColorDrawable) button.getBackground();
int colorId = buttonColor.getColor();
editor.putInt("color_KEY", colorId  );
editor.commit();

你可以这样做，

ColorDrawable buttonColor =(ColorDrawable)button.getBackground(); int colorId = buttonColor.getColor(); SharedPreferences sharedPref = getSharedPreferences("COLOR",MODE_PRIVATE); SharedPreferences.Editor editor = sharedPref.edit(); editor.putInt("color_KEY",id.toString()); editor.commit();
