我在 Android 中遇到了 VectorDrawable 的麻烦。我有一个矢量可绘制文件 (.xml),我想在位图上绘制它。我设法加载此文件并将其绘制在位图上。我可以改变它的填充颜色,但问题是我不能改变它的笔触和颜色。

任何帮助将不胜感激!!!

谢谢!

这是可绘制文件:

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="312dp"
    android:height="312dp"
    android:viewportWidth="312.7"
    android:viewportHeight="312.699">
<path
    android:pathData="M306.35,266.34c0,22.09 -17.91,40.01 -40,40.01L46.35,306.35c-22.09,0 -40,-17.92 -40,-40.01v-219.99c0,-22.11 17.92,-40 40,-40h220c22.09,0 40,17.9 40,40L306.35,266.34z"
    android:strokeWidth="5"
    android:fillColor="@color/transparent"
    android:strokeColor="#231F20"/></vector>

这是我加载并用蓝色填充形状的方式:

Drawable drawable = getResources().getDrawable(R.drawable.graph_rounded_rectangle);
        drawable.setBounds(0, 0, width, height);
        drawable.setColorFilter(new PorterDuffColorFilter(getResources().getColor(R.color.blue), PorterDuff.Mode.MULTIPLY));
        drawable.draw(canvas);

正如Chris Banes他的博客中所说,您可以使用支持库使用以下代码为您的可绘制对象着色:

Drawable drawable = ContextCompat.getDrawable(mContext, R.drawable.ic_asset);

// Wrap the drawable so that future tinting calls work
// on pre-v21 devices. Always use the returned drawable.
drawable = DrawableCompat.wrap(drawable);

// We can now set a tint
DrawableCompat.setTint(drawable, Color.RED);
// ...or a tint list
DrawableCompat.setTintList(drawable, myColorStateList);
// ...and a different tint mode
DrawableCompat.setTintMode(drawable, PorterDuff.Mode.SRC_OVER);

尝试groupxml这样添加:

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    android:width="312dp"
    android:height="312dp"
    android:viewportWidth="312.7"
    android:viewportHeight="312.699">
    <group android:scaleX="1.0" android:scaleY="1.0">
        <path
            android:pathData="M306.35,266.34c0,22.09 -17.91,40.01 -40,40.01L46.35,306.35c-22.09,0 -40,-17.92 -40,-40.01v-219.99c0,-22.11 17.92,-40 40,-40h220c22.09,0 40,17.9 40,40L306.35,266.34z"
            android:strokeWidth="5"
            android:fillColor="@color/transparent"
            android:strokeColor="#231F20"/>
    </group>
</vector>

您只能在 Java API 中访问这些矢量属性

Vector : name
Vector : width
Vector : height
Vector : viewportWidth
Vector : viewportHeight
Vector : tint
Vector : tintMode
Vector : autoMirrored
Vector : alpha

无法使用 java 代码设置矢量的描边(颜色、大小等)。你必须在drawable中处理它。

使用setTint( newColor )方法。

VectorDrawable vd = (VectorDrawable)context.getDrawable( R.drawable.ic_hint );
vd.setTint( 0xffff0000 ); //for red color
