android应用图标快速换色-tint

1.应用场景

项目中的大量图标需要统一换色，可以用下面的方式， 只要自己封装一个工具类就可以了

1.xml中使用tint

<ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/image2"
        android:src="@mipmap/icon"
        android:tint="#FFCDD2"
        android:clickable="true"
    />

2.代码中使用tint

Drawable drawable = ContextCompat.getDrawable(this,R.mipmap.icon);
//简单的使用tint改变drawable颜色
Drawable drawable1 = getTintDrawable(drawable,ContextCompat.getColor(this,R.color.pink));
imageView.setImageDrawable(drawable1);

private Drawable getTintDrawable(Drawable drawable,@ColorInt int color) {
        Drawable.ConstantState state = drawable.getConstantState();
        Drawable drawable1 = DrawableCompat.wrap(state == null ? drawable : state.newDrawable()).mutate();
        drawable1.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
        DrawableCompat.setTint(drawable1, color);
        return drawable1;
    }
