Android填坑之旅（第一篇） 关于应用文本太长为用户提供复制的功能

在Activity或Adapter中

setOnLongClickListener(onLongClickListener);

private View.OnLongClickListener onLongClickListener = new View.OnLongClickListener() {

    @Override    public boolean onLongClick(View v) {        String cardnumber = card_number.getText().toString().trim();        ClipboardManager cm = (ClipboardManager) context.getApplicationContext().getSystemService(Context.CLIPBOARD_SERVICE);        //将文本数据复制到剪贴板        ClipData clip = ClipData.newPlainText("copy", cardnumber);        cm.setPrimaryClip(clip);        T.showCenterToast(context, "复制成功");        return true;    }};
