Android-更改手机方向时调用onTextChanged() [英] Android - onTextChanged() called on when phone orientation is changed

问题描述

我尝试使用EditText实施搜索.每当在EditText请求中键入文本时，便会与onTextChanged()方法中键入的文本一起发送.当我在显示结果的情况下更改手机的方向时，将再次以相同的文本调用onTextChanged()方法.如何避免方向更改时对onTextChanged()方法的多余调用.

I tried to implement search using EditText. whenever a text is typed in the EditText request is sent with the typed text in onTextChanged() method. When I change the orientation of the phone with the results displyed, onTextChanged() method is called again with same text. How can I avoid redundant call to onTextChanged() method on orientation change.

    public void onTextChanged(CharSequence s, int start, int before, int count) {

    final String enteredKeyword = s.toString();


    if(isFragmentVisible && !enteredKeyword.equals("")) {

    searchTimer.cancel();
    searchTimer = new Timer();
    TimerTask searchTask = new TimerTask() {
    @Override
    public void run() {
          searchUser(enteredKeyword);
    }
};
searchTimer.schedule(searchTask, 1500);
Log.i("", enteredKeyword);
}
}

推荐答案

我刚刚遇到了这个问题.所以我将addTextChangedListener移到onCreateView中的EditText的post方法中:

I've got this problem just. So I moved addTextChangedListener to the post method of EditText in the onCreateView:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    ...

    EditText mSearchQuery = findViewById(R.id.search_query);
    mSearchQuery.post(new Runnable() {
            @Override
            public void run() {
                mSearchQuery.addTextChangedListener(new TextWatcher() {
                    @Override
                    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
                    }

                    @Override
                    public void onTextChanged(CharSequence s, int start, int before, int count) {
                        //Some stuff
                    }

                    @Override
                    public void afterTextChanged(Editable s) {
                    }
                });
            }
        });
}
