单击菜单后如何显示吐司？

Question

我有一个 textView，我让它的文本可复制，然后覆盖 onCreateContextMenu：

public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
    //user has long pressed your TextView
    menu.add(0, v.getId(), 0, "Copy");
    TextView yourTextView = (TextView) v;
    ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
    clipboard.setText(yourTextView.getText());

}

我想在点击菜单后显示 toast "copied to clipboard"，我该怎么做？我的第二个问题是为什么不推荐使用 ClipManager？用什么代替？

Answer 1

public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
    //user has long pressed your TextView
    menu.add(0, v.getId(), 0, "Copy");
    TextView yourTextView = (TextView) v;
    ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);

    clipboard.setText(yourTextView.getText());
}

    @Override
public boolean onContextItemSelected(MenuItem item) {

    super.onContextItemSelected(item);

    if (item.getTitle() == "Copy") {
        Toast.makeText(getApplicationContext(), "copied to clipboard", Toast.LENGTH_LONG).show();

    }
    return true;
}

 }

对于 SDK>=15，这将有效

   ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); 
     ClipData clip = ClipData.newPlainText("label for text", "text to copy");
     clipboard.setPrimaryClip(clip);
