我正在为来自此博客的搜索 Activity 实现自定义建议列表 http://weblog.plexobject.com/?p=1689在 doSearchQuery 中无法理解他做了什么。另一件事是当我通过输入例如搜索时月份名称并以“A”开头，它比较它并返回 8 月、4 月等匹配结果，但在建议列表中仅显示“a”，所有匹配结果如“j”包含在 1 月、6 月、7 月。但是在得到 j, j, j 的建议列表中只有不是这个月的名字。我哪里错了或遗漏了我不明白的地方
这是我的 SearchActivity 代码
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.search_activity);
this.setDefaultKeyMode(Activity.DEFAULT_KEYS_SEARCH_LOCAL);
final Intent queryIntent = getIntent();
final String queryAction = queryIntent.getAction();
if (Intent.ACTION_SEARCH.equals(queryAction)) {
this.doSearchQuery(queryIntent);
} else if (Intent.ACTION_VIEW.equals(queryAction)) {
this.doView(queryIntent);
} else {
Log.d(TAG, "Create intent NOT from search");
}
}
@Override
public void onNewIntent(final Intent queryIntent) {
super.onNewIntent(queryIntent);
final String queryAction = queryIntent.getAction();
if (Intent.ACTION_SEARCH.equals(queryAction)) {
this.doSearchQuery(queryIntent);
} else if (Intent.ACTION_VIEW.equals(queryAction)) {
this.doView(queryIntent);
}
}
// here in this didn't under what he did one is getting intent and bundle but where he define it.
private void doSearchQuery(final Intent queryIntent) {
String queryString = queryIntent.getDataString(); // from suggestions
if (query == null) {
query = intent.getStringExtra(SearchManager.QUERY); // from search-bar
}
// display results here
bundle.putString("user_query", queryString);
intent.setData(Uri.fromParts("", "", queryString));
intent.setAction(Intent.ACTION_SEARCH);
queryIntent.putExtras(bundle);
startActivity(intent);
Log.e("query string", "query string "+queryString);
}
private void doView(final Intent queryIntent) {
Uri uri = queryIntent.getData();
String action = queryIntent.getAction();
Intent intent = new Intent(action);
intent.setData(uri);
startActivity(intent);
this.finish();
}
这是我的提供者，我需要单行建议我在第二列评论
public class MySuggestionProvider extends SearchRecentSuggestionsProvider {
public final static String AUTHORITY = MySuggestionProvider.class.getName();
public final static int MODE = DATABASE_MODE_QUERIES;
private final static String TAG = MySuggestionProvider.class.getSimpleName();
private static final String[] COLUMNS = {
"_id", // must include this column
SearchManager.SUGGEST_COLUMN_TEXT_1,
// SearchManager.SUGGEST_COLUMN_TEXT_2,
SearchManager.SUGGEST_COLUMN_INTENT_DATA,
SearchManager.SUGGEST_COLUMN_INTENT_ACTION,
SearchManager.SUGGEST_COLUMN_SHORTCUT_ID };
public MySuggestionProvider() {
setupSuggestions(AUTHORITY, MODE);
}
@Override
public Cursor query(Uri uri, String[] projection, String selection,
String[] selectionArgs, String sortOrder) {
String query = selectionArgs[0];
if (query == null || query.length() == 0) {
return null;
}
MatrixCursor cursor = new MatrixCursor(COLUMNS);
try {
List<String> list = callmyservice(query);
int n = 0;
for (String obj : list) {
cursor.addRow(createRow(Integer.valueOf(n), query, obj));
n++;
}
} catch (Exception e) {
Log.e(TAG, "Failed to lookup " + query, e);
}
return cursor;

return new Object[] { id, // _id
text1, // text1
//text2, // text2
text1, "android.intent.action.SEARCH", // action
SearchManager.SUGGEST_NEVER_MAKE_SHORTCUT };
}
private static final String[] months = {"January", "February","march","April","may","june","july","August","September","octobor",
"november","december"};
List<String> ls2 = new ArrayList<String>();
private List<String> callmyservice(String query){
List<String> ls = new ArrayList<String>();
for(int i=0;i<months.length;i++){
if(months[i].toLowerCase().contains(query.toLowerCase())){
//if(months[i].equalsIgnoreCase(query.toLowerCase())){
ls.add(months[i]);
}
}
ls2.clear();
ls2.addAll(ls);
return ls;
}
}
最佳答案
我找到了实现自定义建议的方法。对此稍作更改，您可以在建议列表中实现搜索建议单行或双行。
对于单行提示我先解释一下
从问题代码开始，我更改了一些并实现了单行建议列表。
从 COLUMN 对象改变这个
private static final String[] COLUMNS = {
"_id", // must include this column
SearchManager.SUGGEST_COLUMN_TEXT_1,
SearchManager.SUGGEST_COLUMN_INTENT_DATA,
SearchManager.SUGGEST_COLUMN_INTENT_EXTRA_DATA,
SearchManager.SUGGEST_COLUMN_SHORTCUT_ID };
现在在 createRow() 中传递对象，一个是 ID，另一个是 query() 方法中的建议列表值。
List<String> list = callmyservice(query);
int n = 0;
for (String obj : list) {
cursor.addRow(createRow(Integer.valueOf(n),obj));
n++;
}
现在像这样实现 createRow()。
private Object[] createRow(Integer id, String text1){
return new Object[] { id, // _id
text1, // text1
text1, // data to sent back to activity and select
text1, // data sent as extra data when select from suggestin list
SearchManager.SUGGEST_NEVER_MAKE_SHORTCUT};
}
好的，这是您实现它时的快照。
好的，现在对于两行搜索建议列表，像这样创建 COLUMN 对象
private static final String[] COLUMNS = {
"_id", // must include this column
SearchManager.SUGGEST_COLUMN_TEXT_1,
SearchManager.SUGGEST_COLUMN_TEXT_2,
SearchManager.SUGGEST_COLUMN_INTENT_DATA,
SearchManager.SUGGEST_COLUMN_INTENT_EXTRA_DATA,
SearchManager.SUGGEST_COLUMN_INTENT_ACTION,
SearchManager.SUGGEST_COLUMN_SHORTCUT_ID };
现在实现 createRow() 方法并像这样从 query() 调用 //查询() 方法 列表 list = callmyservice(query); 诠释 n = 0; 对于(字符串对象:列表){ //此处查询是您当前输入的用于搜索 text_1 的文本 //obj 是通过此查询找到的匹配列表作为结果并显示给 text_2 cursor.addRow(createRow(Integer.valueOf(n), query, obj)); n++;
private Object[] createRow(Integer id, String text1, String name) {
return new Object[] { id, // _id
text1, // text1
text2, // text2
text1, // data to be sent when select from list as query
text2, // data to be sent as extra string when select from list as result
"android.intent.action.SEARCH", // action
SearchManager.SUGGEST_NEVER_MAKE_SHORTCUT };
}
这是两行搜索建议列表的 View
好的，希望对您有所帮助。
