  • but i want to set text color of whole application – Ravi Oct 27 '14 at 10:06
  • The custom textview will update when colour settings is change. Every time the custom textview is create it will check the witch colour the text should be. You should not forget the reload or update the currentview when the colour has been changed – marcel Oct 27 '14 at 10:32

Create a color attribute and store it in SharedPreferences and associate your full app to that color. When user select color from color picker, just change the SharedPreferences property of that color .

Why use SharedPreferences

Because you can't modify resources at runtime. Now full app text color will be changed. 

textview.setTextColor(Color.argb(0,200,0,0)) //r,g,b and fourth parameter is optional

Store three int variable r,g,b in sharedPreferences and set them as above. No need of fourth parameter

  • how to set this color to whole app – Ravi Oct 27 '14 at 10:10
  • You need to set the color for all `TextView` as shown in the answer...there is no shortcut that only one line will change to whole app text color.. – SweetWisher ツ Oct 27 '14 at 10:11

    If the color is fixed, you can create `Custom Textview` and use it in the app..But as you said, the user will select the color from color picker and that color will be set to the textView..then you need to code for all textview manually. – SweetWisher ツ Oct 27 '14 at 10:15
  • i think you have to create a custom theme for it – Zar E Ahmer Oct 27 '14 at 10:23
