java - 访问匿名内部类中的非最终值

Question

我有这 5 个 Edittext 字段，我想使用按钮将这些值写入数据库。对于按钮 Clicklistener，我使用了匿名内部类，但只允许最终值，这意味着我在数据库中写入时将得到空字段。我如何访问这些非最终字段？有什么办法吗？

 public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    EditText yardarea = (EditText)view.findViewById(R.id.yardarea);
    String areaofyard = yardarea.getText().toString();
    EditText brick = (EditText)view.findViewById(R.id.brick);
    final String brickused = brick.getText().toString();
    EditText rcc = (EditText)view.findViewById(R.id.rcc);
    final String rccused = rcc.getText().toString();
    EditText overhead = (EditText)view.findViewById(R.id.overhead);
    final String ovhh = overhead.getText().toString();
    EditText underground = (EditText)view.findViewById(R.id.underground);
    final String ung = underground.getText().toString();

    Button button = (Button) view.findViewById(R.id.register);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            DatabaseAccess databaseAccess = DatabaseAccess.getInstance(getActivity().getApplicationContext());
            databaseAccess.open();
            databaseAccess.insertIntoCriteriaTable(areaofyard, brickused, rccused, ovhh, ung );
            databaseAccess.close();
        }
    });
}

尝试将 EditText 声明为全局

EditText yardarea , brick , rcc,  overhead , underground;

public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
    super.onViewCreated(view, savedInstanceState);

    yardarea = (EditText)view.findViewById(R.id.yardarea);
     brick = (EditText)view.findViewById(R.id.brick);
    rcc = (EditText)view.findViewById(R.id.rcc);
    overhead = (EditText)view.findViewById(R.id.overhead);
    underground = (EditText)view.findViewById(R.id.underground);

    Button button = (Button) view.findViewById(R.id.register);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            String areaofyard = yardarea.getText().toString();
            String brickused = brick.getText().toString();
            String rccused = rcc.getText().toString();
            String ovhh = overhead.getText().toString();
            String ung = underground.getText().toString();

            DatabaseAccess databaseAccess = DatabaseAccess.getInstance(getActivity().getApplicationContext());
            databaseAccess.open();
            databaseAccess.insertIntoCriteriaTable(areaofyard, brickused, rccused, ovhh, ung );
            databaseAccess.close();

        }
    });
}
