添加单词用户词典和检索他们的字典背 [英] Add word to user dictionary and retrieve them back from dictionary

问题描述

我有几个edittexts在用户输入公司名称，客户名称，用途....各种各样的东西我的应用程序。现在，我想补充的话字典编程，因此他们不必重新输入整个单词每次，而不是字典应该建议的话，一旦他们开始输入。

I have few edittexts in my application where user enters company name, client name, purpose....kinds of things. Now I want to add those words to dictionary programmatically and thus they don't have to re-enter the whole word everytime, instead dictionary should suggest the word once they start typing.

我在网上搜索有关上同样和我有类似

I searched on the web regarding the same and I got something like

UserDictionary.Words.addWord(getActivity(), et_client_name.getText().toString(), 1, "", locale);

和我们需要给出两个权限的应用程序：

And we need to give two permissions to the app:

<uses-permission android:name="android.permission.WRITE_USER_DICTIONARY"/>
<uses-permission android:name="android.permission.READ_USER_DICTIONARY"/>

但我的问题是：有一次，我添加使用上述说法的话;如何检索它从字典中回来，并建议用户只要用户开始键入

But my problem is : Once I add words using the above statement; how to retrieve it back from dictionary and suggest user as soon as user starts typing in.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        getFromDictionary();
        suggestClientName();
        et_client_name.addTextChangedListener(this);

    public void getFromDictionary() {
        System.out.println("Inside getFromDictionary");
        ContentResolver resolver = getActivity().getContentResolver();
        String[] projection = new String[]{BaseColumns._ID, UserDictionary.Words.WORD};
        cursor = resolver.query(UserDictionary.Words.CONTENT_URI, projection, null, null, null);
        if (cursor.moveToFirst()) {
            do {
                long id = Integer.parseInt(cursor.getString(0));
                word = cursor.getString(1);
                // Prepare list for autoCompletion
                System.out.println("Inside prepareMyList" + word);
                if (!clientNameList.contains(word))
                    clientNameList.add(word);
                System.out.println("clientNameList::" + clientNameList);
                System.out.println("Word from dictionary is::" + word);
                // do something meaningful
            } while (cursor.moveToNext());
        }
    }

    public void suggestClientName() {
        String newAdd1 = et_client_name.getText().toString();
        if (!clientNameList.contains(newAdd1)) {
            clientNameList.add(newAdd1);
            // update the autocomplete words
            clientNameAdapter = new ArrayAdapter<String>(getActivity(),
                    android.R.layout.simple_dropdown_item_1line, clientNameList);
            et_client_name.setAdapter(clientNameAdapter);
        }
        // display the words in myList for your reference
        String s = "";
        for (int i = 0; i < clientNameList.size(); i++) {
            s += clientNameList.get(i) + "\n";
        }
    }
