Settings for colors in Android

Scenario One: Create a new XML file and then access it in Java with code (the XML file can be accessed directly)

1. Create a new Color.xml under the Res->values folder (the code defined in this file is #rrggbb)

2. Using code access in Java classes

Course_text.settextcolor (Contextcompat.getcolor (This,r.color.yellow));// getResources().getColor(R.color.color_name) discarded

If it is in an XML file, it can be called directly using R.color.yellow.

Scenario Two: Define the color variable in Java and then use the variable.

1. Define Color variables

private int white = 0xffffffff;//Here The color code is #aarrggbb, the first 2 bits is the transparency

2. Using Color variables

Course_layout.setbackgroundcolor (white);
