从动态创建的多个EditText读取文本时出错

Question

我已经创建了多个动态EditText对象（取决于从上一个片段接收到的计数的数量）作为TableRow的一部分。我想将一个侦听器（或多个侦听器，以可行为准）附加到每个EditText并将用户添加的数据读取到String数组中。但是，当我运行该程序时，我只能在最顶层TableRow的一个EditText中输入文本并读取该文本。我无法在进一步的EditText中输入任何文本或阅读其内容。我究竟做错了什么？当我尝试创建customTextWatcher类，尝试简单的editText.getText（）。toString（），尝试使用ArrayList（而不是String数组）并将其遍历到String数组时，这将对您有所帮助。但是，这个错误继续困扰着我！有人可以帮忙吗？将多个EditText读入String数组的最佳方法是什么？

我在演示项目中使用这种类型的动态添加Edittext，如下所示：

UPDATE

我更改代码以使其与您的代码相似，以便我可以找到错误。您还会看到我的完整代码以及布局。它与您的代码相同，我可以输入任何EditText，也可以阅读。如果仍然发现错误，请提供一些布局信息。

DEmo.java为：

public class DEmo extends AppCompatActivity {
 int[] SCORE = {1, 4, 6, 5, 3};
    String[] PLAYERS_LIST = {"aa", "bb", "cc", "dd", "ee"};

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.demo);

        Bundle bundle = new Bundle();
        bundle.putIntArray("SCORE", SCORE);
        bundle.putStringArray("PLAYERS_LIST", PLAYERS_LIST);

        Fragment fragment = new fragment();
        fragment.setArguments(bundle);

        FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
        transaction.replace(R.id.ly, fragment, "Fragment");
        transaction.commitAllowingStateLoss();


    }
}

demo.xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <FrameLayout
        android:id="@+id/ly"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
