我相信您正在寻找以编程方式粘贴的内容。

ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
String pasteData = "";

 // If it does contain data, decide if you can handle the data.
if (!(clipboard.hasPrimaryClip())) {

} else if (!(clipboard.getPrimaryClipDescription().hasMimeType(MIMETYPE_TEXT_PLAIN))) {

    // since the clipboard has data but it is not plain text

} else {

    //since the clipboard contains plain text.
    ClipData.Item item = clipboard.getPrimaryClip().getItemAt(0);

    // Gets the clipboard as text.
    pasteData = item.getText().toString(); 
}
