Android对图片Drawable实现变色示例代码

Drawable wrappedDrawable = DrawableCompat.wrap(drawable);
DrawableCompat.setTint(wrappedDrawable, color);

Drawable wrappedDrawable = DrawableCompat.wrap(drawable);
DrawableCompat.setTintList(wrappedDrawable, colors);

 <item android:state_focused="true" 
   android:color="#ff0000ff"/> <!-- focused --> 
 <item android:color="#ff000000"/> <!-- default --> 
</selector> 

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 
} 

public class DrawableTintUtil {
