如何在“操作"页面中添加图像 [英] How to add image in Action page

问题描述

这是我编写的代码.对于此代码，我需要添加一个图像.那怎么办呢?
实际上，我以一种方式尝试过.但是它可以作为字符串接受，因此请对此提供帮助.

Hi, this is code which I have written. for this code I need to add a image. So how do it.
Actually I tried in one manner. But its accepting as a string so please help in this.

String units;
for (Object object : list) {
	LiveParam liveParam = new LiveParam();
	Object data[] = (Object[]) object;

	// liveParam.setPramCode(data[0].toString());
	liveParam.setPramDispName(data[0].toString());

	// because of UI use issues i make it this
	double parValue = Double.parseDouble(data[1].toString());

	int iValue = 0;
	units = data[5].toString();
	if ((parValue * 100) % 100 == 0) {
		iValue = (int) parValue;
		if (units.equals("STATUSONOFF")) {
			if (iValue == 0) {
				liveParam.setPramValue("<img src='images/off.gif'/>");
				liveParam.setUnits("OFF");
			} else {
				liveParam.setPramValue("<img src='images/on.gif'/>");
				liveParam.setUnits("ON");

			}
		} else if (units.equals("STATUSYESNO")) {
			if (iValue == 0) {
				liveParam.setPramValue("<img src='image/off.gif'/>");
				liveParam.setUnits("NO");
			} else {
				liveParam.setPramValue("<img src='image/on.gif'/>");
				liveParam.setUnits("YES");
			}
		} else {
			liveParam.setPramValue(iValue+"");
			liveParam.setUnits(units);
		}
	} else {
		liveParam.setPramValue(parValue + "");
		liveParam.setUnits(units);
	}

	

	liveParam.setPramType(data[2].toString());
	liveParam.setTimestamp(Utility.getFormattedTimeStamp(
			(Timestamp) data[3], Constants.DATE_TIME_FORMAT));
	liveParam.setCommunicationMedia(data[4].toString());
	liveparamList.add(liveParam);

}

在上面的代码中，我添加了图像.但其接受为字符串.我将等待您的答案

In the above code I have added images. But its accepting as string. I''ll be waiting for your answer

推荐答案

我想您没有正确处理图像.您正在使用相对路径，这通常是无效的.尝试获取完整的绝对路径，然后尝试该路径.

I guess you are not addressing the images right. You are using relative paths, which is often not valid. Try to get the complete, absolute path and try that.
