Android中长按textView弹出一个复制，editText长按弹出粘贴等等

android:textIsSelectable="true"在部分手机上不管用，你试试下面这个

 textview.setOnLongClickListener(new View.OnLongClickListener() {
 @Override
 public boolean onLongClick(View v) {
                        ClipboardManager cmb = (ClipboardManager)context.getSystemService(Context.CLIPBOARD_SERVICE);
                        cmb.setText(textview.getText());
                        ToastUtil.show("已复制");
                        return false;
                    }
                });
