使用之前的代码为:
- public class BookmarksToClipboardActivity extends Activity {
- BookmarkAdapter adapter;
- ListView bookmarkList;
- EditText search;
- BookmarkApplication application;
- Animation fadeIn;
- ClipboardManager clipboardManager;
- @Override
- protected void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- requestWindowFeature(Window.FEATURE_NO_TITLE);
- getWindow().setFlags(FLAG_FULLSCREEN, FLAG_FULLSCREEN);
- setContentView(R.layout.bookmarks);
- bookmarkList = (ListView) findViewById(R.id.bookmarkList);
- search = (EditText) findViewById(R.id.search);
- application = (BookmarkApplication) getApplication();
- fadeIn = AnimationUtils.loadAnimation(this, anim.fade_in);
- clipboardManager = (ClipboardManager) getSystemService(CLIPBOARD_SERVICE);
- View updateBookmarksButton1 = findViewById(R.id.updateBookmarksButton1);
- updateBookmarksButton1.setOnClickListener(new OnClickListener() {
- @Override
- public void onClick(View v) {
- updateBookmarksClicked();
- }
- });
- View updateBookmarksButton2 = findViewById(R.id.updateBookmarksButton2);
- updateBookmarksButton2.setOnClickListener(new OnClickListener() {
- @Override
- public void onClick(View v) {
- updateBookmarksClicked();
- }
- });
- bookmarkList.setOnItemClickListener(new OnItemClickListener() {
- @Override
- public void onItemClick(AdapterView<?> p, View v, int pos, long id) {
- Bookmark selectedBookmark = (Bookmark) p.getAdapter().getItem(pos);
- bookmarkListItemClicked(selectedBookmark);
- }
- });
- initBookmarkList();
- }
- void initBookmarkList() {
- adapter = new BookmarkAdapter(this);
- bookmarkList.setAdapter(adapter);
- }
- void updateBookmarksClicked() {
- UpdateBookmarksTask task = new UpdateBookmarksTask();
- task.execute(search.getText().toString(), application.getUserId());
- }
- private static final String BOOKMARK_URL = //
- "http://www.bookmarks.com/bookmarks/{userId}?search={search}";
- class UpdateBookmarksTask extends AsyncTask<String, Void, Bookmarks> {
- @Override
- protected Bookmarks doInBackground(String... params) {
- String searchString = params[0];
- String userId = params[1];
- RestTemplate client = new RestTemplate();
- HashMap<String, Object> args = new HashMap<String, Object>();
- args.put("search", searchString);
- args.put("userId", userId);
- HttpHeaders httpHeaders = new HttpHeaders();
- HttpEntity<Bookmarks> request = new HttpEntity<Bookmarks>(httpHeaders);
- ResponseEntity<Bookmarks> response = client.exchange( //
- BOOKMARK_URL, HttpMethod.GET, request, Bookmarks.class, args);
- Bookmarks bookmarks = response.getBody();
- return bookmarks;
- }
- @Override
- protected void onPostExecute(Bookmarks result) {
- adapter.updateBookmarks(result);
- bookmarkList.startAnimation(fadeIn);
- }
- }
- void bookmarkListItemClicked(Bookmark selectedBookmark) {
- clipboardManager.setText(selectedBookmark.getUrl());
- }
- }
使用之后的代码为:
- @NoTitle
- @Fullscreen
- @EActivity(R.layout.bookmarks)
- public class BookmarksToClipboardActivity extends Activity {
- BookmarkAdapter adapter;
- @ViewById
- ListView bookmarkList;
- @ViewById
- EditText search;
- @App
- BookmarkApplication application;
- @RestService
- BookmarkClient restClient;
- @AnimationRes
- Animation fadeIn;
- @SystemService
- ClipboardManager clipboardManager;
- @AfterViews
- void initBookmarkList() {
- adapter = new BookmarkAdapter(this);
- bookmarkList.setAdapter(adapter);
- }
- @Click({R.id.updateBookmarksButton1, R.id.updateBookmarksButton2})
- void updateBookmarksClicked() {
- searchAsync(search.getText().toString(), application.getUserId());
- }
- @Background
- void searchAsync(String searchString, String userId) {
- Bookmarks bookmarks = restClient.getBookmarks(searchString, userId);
- updateBookmarks(bookmarks);
- }
- @UiThread
- void updateBookmarks(Bookmarks bookmarks) {
- adapter.updateBookmarks(bookmarks);
- bookmarkList.startAnimation(fadeIn);
- }
- @ItemClick
- void bookmarkListItemClicked(Bookmark selectedBookmark) {
- clipboardManager.setText(selectedBookmark.getUrl());
- }
- }
- @Rest("http://www.bookmarks.com")
- public interface BookmarkClient {
- @Get("/bookmarks/{userId}?search={search}")
- Bookmarks getBookmarks(String search, String userId);
- }
