如何从android中的FlowTextView中选择和复制文本

Question

我正在使用flowtextview在图像周围流动。我想在长时间触摸时选择文本..如何为流文本视图执行此操作..到目前为止我做了什么

txtDesc = (FlowTextView) findViewById(R.id.tDescription);
txtDesc.setText(temp_desc);
CharSequence stringYouExtracted = text.getText();
int startIndex = text.getSelectionStart();
int endIndex = text.getSelectionEnd();
stringYouExtracted = ( stringYouExtracted).subSequence(startIndex, endIndex);
getSystemService(CLIPBOARD_SERVICE);
if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.ECLAIR) 
{
   android.text.ClipboardManager clipboard = (android.text.ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
    clipboard.setText(stringYouExtracted);
} else {
    ClipboardManager clipboard = (ClipboardManager) getSystemService(Context.CLIPBOARD_SERVICE);
  System.err.println("clipboard to select"+clipboard);
}
