                  推荐答案

                  我得到了解决方案:我创建了一项服务:在 oncreate 中:

                  I got solutions: I create one service : on that in oncreate :

                           ClipboardManager clipBoard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
                           clipBoard.addPrimaryClipChangedListener(new ClipboardListener());
                  

                  并添加服务:

                          class ClipboardListener implements
                          ClipboardManager.OnPrimaryClipChangedListener {
                          public void onPrimaryClipChanged() {
                          ClipboardManager clipBoard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
                          CharSequence pasteData = "";
                          ClipData.Item item = clipBoard.getPrimaryClip().getItemAt(0);
                          pasteData = item.getText();
                          Toast.makeText(getApplicationContext(), "copied val=" + pasteData,
                                  Toast.LENGTH_SHORT).show();
                  
                      }
                  }
