When you change the color of TextView in XML, you change the textColor property like android:textColor="#FF0000" In the code above, holder is a class and text is a TextView. Red is strings with RGB value of #FF0000. But if you look at the results, the color is a bit different from red. According to the related document, the int is delivered to the setTextColor, but is that only the reference value of the resource? Or something else?holder.text.setTextColor(R.color.Red);
holder.text.setTextColor(Color.RED);
I think you should change it like this. The red color comes out well when I do it like the chords above.
There are many methods in the Color class that have the same effect.
Color.parseColor text.setTextColor(Color.parseColor("#FFFFFF"));
Color.rgb and Color.argb holder.text.setTextColor(Color.rgb(200,0,0)); holder.text.setTextColor(Color.argb(0,200,0,0));
And you can define the color directly in xml.
<color name="color name">#f00</color>
GetResources().getColor() is defined from Android M ContextCompat.getColor(context, R.color.Color Name); You can use it like this.
Lastly,
AA represents alpha and RRGGBB represents RGB values respectively.
