Appcelerator ti.paint模塊不會在Android上加載圖像

Question

我在android上的ti.paint模塊出錯。 每當我嘗試設置圖像時，我的應用程序就會崩潰（在iOS上運行正常），我嘗試了以下代碼：

var paintView = Paint.createPaintView({
    top:0, right:0, bottom:80, left:0,
    image : "images/doge.png",
    eraseMode : true,
    strokeWidth : 70
});

和

image : "/images/doge.png"

也

image = "http://dogr.io/doge.png"

最后

var dogeFile = Titanium.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, 'images/doge.png');
var paintView = Paint.createPaintView({
    top:0, right:0, bottom:80, left:0,
    image : dogeFile.nativePath,
    eraseMode : true,
    strokeWidth : 70
});

但是，應用程序每次在Android上崩潰（在iOS上運行正常）。

我也嘗試過使用jpeg圖片，甚至使用NULL值。

這是我在控制台中收到的錯誤消息

我正在運行Titanium SDK3.2.3.GA。

任何幫助，將不勝感激。

Answer 1

我目前在ti.paint上工作，我在Android上遇到了同樣的問題。 Android的管理視圖與Titanium的管理視圖不同，那么這就產生了問題。這個主意是使用主線程。

這里是PaintViewProxy.java模塊的更改：

@Kroll.setProperty
@Kroll.method
public void setImage(String imagePath) {
    final String imgPath = imagePath;
    getActivity().runOnUiThread(new Runnable() {
        @Override
        public void run() {
            paintView.setImage(imgPath);
        }
    });
}

重新編譯它，它應該工作，它對我有用。 希望您有幫助...
