首页 > IT职业 > IT生活 > Android -对图片Drawable进行变色
Drawable对象的来源不限制,可以是从资源getResource().getDrawable(int resourceId)也可以是其他的方式得到的Drawable
Drawable wrappedDrawable = DrawableCompat.wrap(drawable);
DrawableCompat.setTint(wrappedDrawable, color);
2.采用ColorStateList来改变Drawable
Drawable wrappedDrawable = DrawableCompat.wrap(drawable);
DrawableCompat.setTintList(wrappedDrawable, colors);
3.介绍一下ColorStateList <!-- pressed --> <!-- focused --> <!-- default --> Java代码(用于改变按钮的字体颜色)
Button btn=(Button)findViewById(R.id.btn);
Resources resource=(Resources)getBaseContext().getResources();
ColorStateList csl=(ColorStateList)resource.getColorStateList(R.color.button_text);
if(csl!=null){
btn.setTextColor(color_state_list);//设置按钮文字颜色
}
4.安利一个朋友封装的工具类 public class DrawableTintUtil {
/**
* Drawable 颜色转化类
*
* @param drawable
* @param color资源
* @return 改变颜色后的Drawable
*/
public static Drawable tintDrawable(@NonNull Drawable drawable, int color) {
Drawable wrappedDrawable = DrawableCompat.wrap(drawable);
DrawableCompat.setTint(wrappedDrawable, color);
return wrappedDrawable;
}
/**
* Drawable 颜色转化类
*
* @param drawable 源Drawable
* @param ColorStateList
* @return 改变颜色后的Drawable
*/
public static Drawable tintListDrawable(@NonNull Drawable drawable, ColorStateList colors) {
Drawable wrappedDrawable = DrawableCompat.wrap(drawable);
DrawableCompat.setTintList(wrappedDrawable, colors);
return wrappedDrawable;
}
}
