我正在使用下面的代码来更改不同布局的背景色，以减少我想使用辅助类的代码。怎么做到呢？我应该用什么变量来称呼课程？
如果我想为每种布局使用不同的背景色，应该怎么称呼课程？
final NavigationView navigationView =(NavigationView)findViewById(R.id.navigation_view);
ShapeDrawable.ShaderFactory sf1 = new ShapeDrawable.ShaderFactory() {
@Override
public Shader resize(int width, int height) {
LinearGradient lg1 = new LinearGradient(0, 0, height, width,
new int[]{
Color.rgb(238,162,173),
Color.rgb(70, 130, 160),
Color.rgb(99, 184, 223),
Color.rgb(205,198,115),
Color.rgb(176, 226, 155),
},
new float[]{0,.1f,.51f,.52f,.11f}, Shader.TileMode.REPEAT);
return lg1;
}
};
PaintDrawable p = new PaintDrawable();
p1.setShape(new RectShape());
p1.setShaderFactory(sf1);
p1.setCornerRadius(10.8f);
navigationView.setBackground((Drawable)p1);
final LinearLayout layout =(LinearLayout)findViewById(R.id.ll);
ShapeDrawable.ShaderFactory sf2 = new ShapeDrawable.ShaderFactory() {
@Override
public Shader resize(int width, int height) {
LinearGradient lg2 = new LinearGradient(0, 0, height, width,
new int[]{
Color.rgb(238,162,173),
Color.rgb(70, 130, 160),
Color.rgb(99, 184, 223),
Color.rgb(205,198,115),
Color.rgb(176, 226, 255),
},
new float[]{0,.1f,.51f,.52f,.11f}, Shader.TileMode.REPEAT);
return lg2;
}
};
PaintDrawable np = new PaintDrawable();
p2.setShape(new RectShape());
p2.setShaderFactory(sf2);
p2.setCornerRadius(10.8f);
layout.setBackground((Drawable)p2);
