Question

大家好，我在android的文本编辑器中工作，我想优化我的文本编辑器。当我的文本编辑器有100行代码时，它变得迟钝这是我的实现代码：

private void onEditorListener() {
    edtEditor.addTextChangedListener(new TextWatcher() {
        @Override
        public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
        }

        @Override
        public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {
            _lastTypeTime = new Date();
        }

        @Override
        public void afterTextChanged(final Editable s) {
            last_text_edit = System.currentTimeMillis();
            handler.postDelayed(runnable, idle_min);
            runnable = new Runnable() {
                @Override
                public void run() {
                    try {
                        if (System.currentTimeMillis() >= (last_text_edit + idle_min - 500)) {
                            // user hasn't changed the EditText for longer than
                            // the min delay (with half second buffer window)
                            textHighLighter(s);  // your queries
                            if (!already_queried) { // don't do this stuff twice.
                                already_queried = true;
                                //textHighLighter(s);  // your queries
                            }
                        }
                        //already_queried = false;
                        handler.removeCallbacks(runnable);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            };
        }
    });
}

试试这个。

在字段变量中添加private boolean blocks = false;。

private void onEditorListener() {
    edtEditor.addTextChangedListener(new TextWatcher() {
        @Override
        public void onTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {}

        @Override
        public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) {}

        @Override
        public void afterTextChanged(final Editable s) {
            if (blocks) {
                return;
            }
            blocks = true;
            textHighLighter(s);  // your queries
            blocks = false;
        }
}
