从TextView的Andr​​oid上复制文本 [英] Copy text from TextView on Android

问题描述

我有一个的ListView ，其中每个项目是的TextView 。

I have a ListView where each item is a TextView.

我想启用类似于长preSS行为的EditText ，随着像全选，全部剪切项显示默认的上下文菜单， 全部复制，等等。

I want to enable the long press behaviour similar to an EditText that displays the default context menu with items like "Select all", "Cut all", "Copy all", etc.

有一种简单的方法，使本作的TextView ？

Is there an easy way to enable this for a TextView?

推荐答案

我觉得我有一个解决方案。 只需致电
registerForContextMenu（yourTextView）;

I think I have a solution. Just call
registerForContextMenu(yourTextView);

和您的的TextView 将被注册为接收上下文菜单事件。

and your TextView will be registered for receiving context menu events.

然后重写 onCreateContextMenu 在活动：

@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    //user has long pressed your TextView
    menu.add(0, v.getId(), 0, "text that you want to show in the context menu - I use simply Copy");

    //cast the received View to TextView so that you can get its text
    TextView yourTextView = (TextView) v;

    //place your TextView's text in clipboard
    ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); 
    clipboard.setText(yourTextView.getText());
}

希望这有助于你和其他人寻找一种方式来复制从文本的TextView
