使用 ClipBoardManager android 在文件管理器中复制/粘贴实现

Question

我正在寻找一种有效且高效的方法来实现复制粘贴功能。使用 ClipBoardManager 类如何实现这一点。到处都显示了如何复制使用剪辑数据的文本。我想复制一个文件或者一个文件夹。提前致谢

Answer 1

ClipboardManager myClipboard;
myClipboard = (ClipboardManager)getSystemService(CLIPBOARD_SERVICE);

复制数据

ClipData myClip;
String text = "hello world";
myClip = ClipData.newPlainText("text", text);
myClipboard.setPrimaryClip(myClip);

粘贴数据

ClipData abc = myClipboard.getPrimaryClip();
ClipData.Item item = abc.getItemAt(0);
String text = item.getText().toString();

如果你想复制/粘贴一个文件，你应该使用Java Standard I/O

这是一种将文件从一个位置复制到另一个位置的方法：

private void copyFile(String inputPath, String inputFile, String outputPath) {

    InputStream in = null;
    OutputStream out = null;
    try {

        //create output directory if it doesn't exist
        File dir = new File (outputPath); 
        if (!dir.exists())
        {
            dir.mkdirs();
        }


        in = new FileInputStream(inputPath + inputFile);        
        out = new FileOutputStream(outputPath + inputFile);

        byte[] buffer = new byte[1024];
        int read;
        while ((read = in.read(buffer)) != -1) {
            out.write(buffer, 0, read);
        }
        in.close();
        in = null;

            // write the output file (You have now copied the file)
            out.flush();
        out.close();
        out = null;        

    }  catch (FileNotFoundException fnfe1) {
        Log.e("tag", fnfe1.getMessage());
    }
            catch (Exception e) {
        Log.e("tag", e.getMessage());
    }

}
