从文本观察器更改 imeOptions

Changing imeOptions from a text watcher

我正在尝试从 textwatcher 更改 imeOptions,在检测到编辑文本上的“@”符号时,我需要将其 imeOptions 从 "Go" 更改为 "Done"。请指教

 etSample.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

        }

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
            if ((charSequence+"").contains("@")){
                etSample.setBackgroundColor(Color.BLACK);
                etSample.setTextColor(Color.WHITE);
                etSample.setImeOptions(EditorInfo.IME_ACTION_NEXT);
                etSample.requestFocus();
            }else {
                etSample.setBackgroundColor(Color.WHITE);
                etSample.setTextColor(Color.BLACK);
                etSample.setImeOptions(EditorInfo.IME_ACTION_DONE);
                etSample.requestFocus();
            }
        }

        @Override
        public void afterTextChanged(Editable editable) {

        }
    });

这不起作用(它总是显示完成)

尝试将 etSample.requestFocus() 替换为 etSample.setInputType(InputType.TYPE_CLASS_TEXT)
