我正在使用内容提供商来提供搜索建议,但我在处理建议点击时遇到了问题。我解释说搜索效果很好,但是当我单击建议时,我会转到搜索活动,但什么也没有。我的搜索代码:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.simple_list_item_2);
DataBaseUtil.startDataBase(getApplicationContext());
// Get the intent, verify the action and get the query
Intent intent = getIntent();
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
Cursor cursorAdapter = GetListResult(query);
if (cursorAdapter != null) {
cursorAdapter.moveToFirst();
}
startManagingCursor(cursorAdapter);
String[] from = new String[] { SearchManager.SUGGEST_COLUMN_ICON_1,
BaseColumns._ID, SearchManager.SUGGEST_COLUMN_TEXT_1,
"project_id" };
int[] displayViews = new int[] { R.id.row_image, R.id.name_entry,
R.id.name_id, R.id.name_descrption };
final SimpleCursorAdapter listAdapter = new SimpleCursorAdapter(
this, R.layout.layout_row, cursorAdapter, from,
displayViews);
final ListView list = (ListView) findViewById(android.R.id.list);
list.setAdapter(listAdapter);
list.setOnItemClickListener(new ListView.OnItemClickListener() {
public void onItemClick(AdapterView<?> l, View v, int position,
long id) {
Cursor cursor = (Cursor) listAdapter.getItem(position);
String i = String.valueOf(cursor.getInt(cursor
.getColumnIndex("project_id")));
Intent intent = new Intent(ItemIntent.this,
AcceuilProjet.class);
intent.putExtra("folderId", "0");
intent.putExtra("projectName", " ");
intent.putExtra("projectId", Long.valueOf(i));
startActivity(intent);
}
});
}
}
这是我的提供者
@Override
public Cursor query(Uri uri, String[] projection, String selection,
String[] selectionArgs, String sortOrder) {
String[] columns = new String[] {
BaseColumns._ID,
ProjectPersistence.KEY_WORD,
ProjectPersistence.KEY_DEFINITION,
/* SearchManager.SUGGEST_COLUMN_SHORTCUT_ID,
(only if you want to refresh shortcuts) */
SearchManager.SUGGEST_COLUMN_INTENT_DATA_ID};
Cursor rtnCursor = null;
Cursor rtnCursorProject = null;
// Cursor rtnCursorMessage = null;
String word = uri.getLastPathSegment();
Log.d(TAG, " Search Provider query, word: " + word);
if (!word.equals(SEARCH_QUERY)) {
try {
rtnCursorProject = ProjectPersistence.fetchProjectCursor(word);
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InstantiationException e) {
e.printStackTrace();
}
rtnCursor = getMatrixCursor(rtnCursorProject);
} else if (word.equals(SEARCH_QUERY_VIEW)) {
// Handle a suggestions click (because the suggestions all use
// ACTION_VIEW)
try {
rtnCursorProject = ProjectPersistence.fetchProjectCursor(word);
} catch (IllegalAccessException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InstantiationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Toast.makeText(getContext(), "anything", Toast.LENGTH_SHORT).show();
Log.d("Provider", "this is a item click");
}
return rtnCursor;
}
如果可以,请你帮助我
