系统剪切板：
系统剪切板一般支持String文本类型和Image图像类型：
String文本类型
插入：
Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();//获取系统剪切板
String str = "哈哈";//设置字符串
StringSelection selection = new StringSelection(str);//构建String数据类型
clipboard.setContents(selection, selection);//添加文本到系统剪切板
获取：
Transferable content = clipboard.getContents(null);//从系统剪切板中获取数据
if (content.isDataFlavorSupported(DataFlavor.stringFlavor)) {//判断是否为文本类型
String text = (String) content.getTransferData(DataFlavor.stringFlavor);//从数据中获取文本值
if (text == null) {
return;
}
System.out.println(text);
}
自定义剪切板：
首先需要写一个数据类：
public class TestSelection implements Transferable, ClipboardOwner {
public static final DataFlavor rangeFlavor = new DataFlavor(RangeDataModel.class, "Report Range");//class为自定义的java类 字串随便
private static final DataFlavor[] flavors = { rangeFlavor };
private Object data;
public TestSelection(Object data) {
this.data = data;
}
@Override
public Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException, IOException {
if (flavor.equals(flavors[RANGE])) {
return data;
} else {
throw new UnsupportedFlavorException(flavor);
}
}
@Override
public DataFlavor[] getTransferDataFlavors() {
return (DataFlavor[]) flavors.clone();
}
@Override
public boolean isDataFlavorSupported(DataFlavor flavor) {
for (int i = 0; i < flavors.length; i++) {
if (flavor.equals(flavors[i])) {
return true;
}
}
return false;
}
@Override
public void lostOwnership(Clipboard clipboard, Transferable contents) {
// TODO Auto-generated method stub
}
}
然后就是设置值：
Clipboard clipboard = new Clipboard("clipboardName");//创建自定义剪切板对象
ReportSelection content = new ReportSelection(data);//构建数据对象 data为数据类型java类的对象
clipboard.setContents(content, null);
获取值：
Transferable content = clipboard.getContents(null);//注意 自定义剪切板必须给null参数
if (content.isDataFlavorSupported(ReportSelection.rangeFlavor)) {
RangeDataModel data = (RangeDataModel) content.getTransferData(ReportSelection.rangeFlavor);
System.out.println(data);
}
