android - 找不到接受参数类型“android.text.TextWatcher”的 android.widget.EditText android:onTextChanged 的​​设置器

Question

在 android 中使用数据绑定实现 TextWatcher 时出现问题。如何解决此问题请帮助。

这是我的 MainActivity 类代码。

BottomSheetDialog mBottomSheetDialog = new BottomSheetDialog(SplashActivity.this,R.style.AppBottomSheetDialogTheme);
        mBottomSheetDialog.setCancelable(false);
        mBottomSheetDialog.setCanceledOnTouchOutside(true);
        DialogBottomSheetLoginBinding bottomSheetLoginBinding= DataBindingUtil.inflate(LayoutInflater.from(this), R.layout.dialog_bottom_sheet_login, null, false);
        mBottomSheetDialog.setContentView(bottomSheetLoginBinding.getRoot());
        mBottomSheetDialog.show();

    mViewModel = new EditTextViewModel();
    bottomSheetLoginBinding.setData(mViewModel);

public EditTextViewModel(){
    this.textWatcher= getTextWatcherIns();
}

private TextWatcher getTextWatcherIns() {
    return new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {
            //do some thing
        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            //do some thing

        }

        @Override
        public void afterTextChanged(final Editable s) {
            if (s.length() >= 10) {

                timer = new Timer();
                timer.schedule(new TimerTask() {
                    @Override
                    public void run() {
                        // TODO: do what you need here (refresh list)
                        // you will probably need to use
                        // runOnUiThread(Runnable action) for some specific
                        // actions
                        Log.d("OntextChange",s.toString());
                    }

                }, DELAY);
            }
        }

    };
}
public TextWatcher getTextWatcher() {
    return textWatcher;
}

public void setTextWatcher(TextWatcher textWatcher) {
    this.textWatcher = textWatcher;
}

@BindingAdapter("textChangedListener")
public static void bindTextWatcher(EditText editText, TextWatcher textWatcher) {
    editText.addTextChangedListener(textWatcher);
}

当我构建项目时，它显示找不到接受参数类型'android.text.TextWatcher'的设置器

如果绑定适配器提供了设置器，请检查适配器是否正确注释以及参数类型是否匹配。

在你的使用EditText

<EditText
    app:addTextChangedListener="..."
   ../>

代替：

<EditText
   android:onTextChanged="@{data.textWatcher}"
   ../>
