安卓 14 上 Paint.setColor() 方法报错

[pansong291]

1. Autox.js 版本：7.0.2
2. Autox.js 下载渠道：https://github.com/kkevsekk1/AutoX/releases
3. Android 版本：Android 14
4. Android 机型：小米13
5. Android 系统类别：MIUI

代码如下：

const window = floaty.window(
  <frame gravity="center">
      <text id="text" text="点击可调整位置" textSize="16sp"/>
      <canvas id="board" w="*" h="*"/>
  </frame>
);

window.exitOnClose();

window.text.click(()=>{
  window.setAdjustEnabled(!window.isAdjustEnabled());
});

//画笔
var paint = new Paint();
//设置画笔颜色
paint.setColor(colors.parseColor("#ff0ff0ff"));

window.board.on("draw", function(canvas){
    var w = canvas.getWidth();
    var h = canvas.getHeight();
    canvas.drawRect(200,200,500,500,paint);
});
setInterval(()=>{}, 1000);

Wrapped java.lang.IllegalArgumentException: Invalid ID, must be in the range [0..18)

然后我把设置颜色那里的代码改成了这样的字符串：

paint.setColor("#ff0ff0ff");

得到如下报错：

23:05:58.254/E: The choice of Java method android.graphics.Paint.setColor matching JavaScript argument types (string) is ambiguous; candidate methods are: 
    void setColor(int)
    void setColor(long) (/storage/emulated/0/脚本/test.js#17)

@kkevsekk1

原因是 Android O 及之后，Paint 类的 setColor 方法被重载了，有两个签名：

public void setColor(int i);
public void setColor(long l);

Rhino 无法判断应该调用哪一个。这是 Rhino 无法解决的一个痛点，目前的解决办法： https://github.com/kkevsekk1/AutoX/issues/1180#issuecomment-2339471235

看起来似乎是优先调用了 setColor(long) 才报的错。

那么可能的解决方案：

try {
    paint.setColor(colors.pack(colors.parseColor("#ff0ff0ff")));
} catch(e) {
    paint.setColor(colors.parseColor("#ff0ff0ff"));
}

其中 colors.pack 详见 https://developer.android.google.cn/reference/android/graphics/Color#pack(int)
