如何在ClickableSpan中单击后禁用打开的键盘

import android.text.style.ClickableSpan;
import android.view.View;
import android.view.inputmethod.InputMethodManager;
import android.widget.TextView;

public class CustomClickableSpan extends ClickableSpan {
    private TextView textView;

    public CustomClickableSpan(TextView textView) {
        this.textView = textView;
    }

    @Override
    public void onClick(View widget) {
        // 隐藏键盘
        InputMethodManager imm = (InputMethodManager) textView.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(textView.getWindowToken(), 0);

        // 设置TextView可触摸获取焦点
        textView.setFocusableInTouchMode(true);

        // 请求TextView获取焦点
        textView.requestFocus();
    }
}

TextView textView = findViewById(R.id.textView);
String text = "点击这里禁用键盘";
SpannableString spannableString = new SpannableString(text);
ClickableSpan clickableSpan = new CustomClickableSpan(textView);
spannableString.setSpan(clickableSpan, 0, text.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
textView.setText(spannableString);
textView.setMovementMethod(LinkMovementMethod.getInstance());
