前言
本文主要给大家介绍了Android中图片DrawableCompat利用setTint()对图片Drawable进行变色的相关内容,分享出来供大家参考学习,下面话不多说了,来一起看看详细的介绍:
1.利用color资源对Drawable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
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:color="#ffff0000"/> <!-- pressed --> <item android:state_focused="true" android:color="#ff0000ff"/> <!-- focused --> <item android:color="#ff000000"/> <!-- default --> </selector>
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; } }
