java - 无法以编程方式设置 EditText ID

Question

我正在创建动态数量的 editText，并希望最终提取每个 editText 的 ID 以在 editText 上调用 .getText()。

但是，我注意到很难以编程方式设置 ID，因此我改用 .setTag() 方法:

private void createAnswerChoice(int answerNumber) {
    ViewGroup layout = (ViewGroup) mRootView.findViewById(R.id.create_poll_questions_answer_layout);
    EditText editText = new EditText(getActivity());
    editText.setHint(getResources().getString(R.string.answer_text) + " " + answerNumber);
    editText.setSingleLine(true);
    editText.setImeOptions(EditorInfo.IME_ACTION_DONE);
    String editTextID = ((getResources().getString(R.string.created_answer_editText_id))+String.valueOf(answerNumber));
    editText.setTag(editTextID);
    Toast.makeText(getActivity().getApplicationContext(), editTextID, Toast.LENGTH_SHORT).show();
    LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
    editText.setLayoutParams(layoutParams);
    TextInputLayout newAnswer = new TextInputLayout(getActivity());
    newAnswer.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
    newAnswer.addView(editText, layoutParams);
    layout.addView(newAnswer);
}

如果我知道标签而不是 ID，如何获取每个 editText 的值？另外，.setTag() 方法的用途是什么(它与 .setID() 有什么关系？)

Answer 1

在res/values/id.xml中创建资源文件(id.xml)

  <?xml version="1.0" encoding="utf-8"?>
  <resources>
   <item
    type="id"
    name="edittext_hello" />
  </resources>

然后设置，

 editText.setId(R.id.edittext_hello);
