在您的活动中，只需使用以下代码：

int customNormalColorFromServer = Color.WHITE; // Replace value with your color retreiving logic
int customFocusedColorFromServer = Color.GRAY; // Replace value with your color retreiving logic

ColorStateList colorStateList = new ColorStateList(new int[][] {
                    new int[] {android.R.attr.state_selected},
                    new int[] {-android.R.attr.state_selected}
                },
                new int[] {customFocusedColorFromServer, customNormalColorFromServer}
    );

NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setItemIconTintList(colorStateList);

Answer 2

navigationView.setItemBackground（Color.parseColor（＆＃34;＃000＆＃34））;
