如何在此代碼中複製textView的所有部分？

Question

我從Naddy先生這段代碼拷貝的TextView在API剪貼板7

TextView textView=(TextView)findViewById(R.id.textView1); 
registerForContextMenu(textView); 

然後覆蓋onCreateContextMenu -

@Override 
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { 
    //user has long pressed your TextView 
    menu.add(0, v.getId(), 0, "Copy"); 

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

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

它的工作原理.....但用戶可以複製所有的textview .................我想允許用戶，如果他想要他可以複製文本視圖的部分....也許用戶想複製一些文字不是所有的textview？ ??????

我該怎麼辦？

你試過嗎？

TextView tv; 
String stringYouExtracted = tv.getText().toString; 
int startIndex = tv.getSelectionStart(); 
int endIndex = tv.getSelectionEnd(); 
stringYouExtracted = stringYouExtracted.subString(startIndex, endIndex); 
ClipboardManager clipboard = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE); 
clipboard.setText(stringYouExtracted);
