在自定义TextWatcher中更新适配器/回收视图

public class CustomTextWatcher implements TextWatcher {
    private ArrayAdapter<String> adapter;

    public CustomTextWatcher(ArrayAdapter<String> adapter) {
        this.adapter = adapter;
    }

    @Override
    public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
        // 在文本改变之前执行的操作
    }

    @Override
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
        // 在文本改变时执行的操作
        // 根据文本内容的改变，更新适配器
        adapter.notifyDataSetChanged();
    }

    @Override
    public void afterTextChanged(Editable editable) {
        // 在文本改变之后执行的操作
    }
}

ArrayAdapter<String> adapter = new ArrayAdapter<>(context, android.R.layout.simple_list_item_1, data);
EditText editText = findViewById(R.id.editText);

CustomTextWatcher textWatcher = new CustomTextWatcher(adapter);
editText.addTextChangedListener(textWatcher);
