android - 带有 IMEOption DONE 或 NEXT 的多行 EditText 不起作用

Question

我正在尝试在多行编辑文本上查看带有下一个按钮的键盘。但这对我不起作用。

Answer 1

您不能在多行编辑文本上设置 IME 操作，因为将用于下一个/完成/搜索/...操作的键盘按钮必然是一个 ENTER/RETURN 按钮以插入换行符。

Answer 2

不要害怕，这是可以做到的。虽然下面的代码完美运行，但不幸的是我不记得我从哪里得到代码，所以不能给作者他/她应得的荣誉。

////////////Code to Hide SoftKeyboard on Enter (DONE) Press///////////////
editText.setRawInputType(InputType.TYPE_CLASS_TEXT|InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD|InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
editText.setImeActionLabel("DONE",EditorInfo.IME_ACTION_DONE);              //Set Return Carriage as "DONE"
editText.setImeOptions(EditorInfo.IME_ACTION_DONE);

editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) 
    {
                if (event == null) {
                    if (actionId == EditorInfo.IME_ACTION_DONE) {
                        // Capture soft enters in a singleLine EditText that is the last EditText
                        // This one is useful for the new list case, when there are no existing ListItems
                        editText.clearFocus();
                        //hide SoftKeyboard
                        InputMethodManager inputMethodManager = (InputMethodManager)  getActivity().getSystemService(Activity.INPUT_METHOD_SERVICE);
                        inputMethodManager.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);
                    }

                    else if (actionId == EditorInfo.IME_ACTION_NEXT) {
                        // Capture soft enters in other singleLine EditTexts
                    } else if (actionId == EditorInfo.IME_ACTION_GO) {
                    } else {
                        // Let the system handle all other null KeyEvents
                        return false;
                    }
                } 
        else if (actionId == EditorInfo.IME_NULL) {
                    // Capture most soft enters in multi-line EditTexts and all hard enters;
                    // They supply a zero actionId and a valid keyEvent rather than
                    // a non-zero actionId and a null event like the previous cases.
                    if (event.getAction() == KeyEvent.ACTION_DOWN) {
                        // We capture the event when the key is first pressed.
                    } else {
                        // We consume the event when the key is released.
                        return true;
                    }
                } 
        else {
                    // We let the system handle it when the listener is triggered by something that
                    // wasn't an enter.
                    return false;
                }
                return true;
        }
});

为了将焦点传递给Next EditText，请使用edit_text2.requestFocus()并删除 Hide SoftKeyboard 代码。
