Examples with CursorLoader android.content.CursorLoader used on opensource projects

Example 1 with CursorLoader

use of android.content.CursorLoader in project KJFrameForAndroid by kymjs.

the class FileUtils method uri2File.

/**
     * 把uri转为File对象
     */
public static File uri2File(Activity aty, Uri uri) {
    if (SystemTool.getSDKVersion() < 11) {
        // 在API11以下可以使用：managedQuery
        String[] proj = { MediaStore.Images.Media.DATA };
        @SuppressWarnings("deprecation") Cursor actualimagecursor = aty.managedQuery(uri, proj, null, null, null);
        int actual_image_column_index = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        actualimagecursor.moveToFirst();
        String img_path = actualimagecursor.getString(actual_image_column_index);
        return new File(img_path);
    } else {
        // 在API11以上：要转为使用CursorLoader,并使用loadInBackground来返回
        String[] projection = { MediaStore.Images.Media.DATA };
        CursorLoader loader = new CursorLoader(aty, uri, projection, null, null, null);
        Cursor cursor = loader.loadInBackground();
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return new File(cursor.getString(column_index));
    }
}

            // Create and return the Loader.
            loader = getCursorLoaderInstance(mContext, mSessionsUri, ExploreIOQueryEnum.SESSIONS.getProjection(), null, null, ScheduleContract.Sessions.SORT_BY_TYPE_THEN_TIME);
            break;
        case TAGS:

            LOGI(TAG, "Starting cards query: " + currentTime);
            loader = getCursorLoaderInstance(mContext, ScheduleContract.Cards.CONTENT_URI, ExploreIOQueryEnum.CARDS.getProjection(), " ? > " + ScheduleContract.Cards.DISPLAY_START_DATE + " AND  ? < " + ScheduleContract.Cards.DISPLAY_END_DATE + " AND " + ScheduleContract.Cards.ACTION_TYPE + " IN ('" + EventCard.ACTION_TYPE_LINK + "', '" + EventCard.ACTION_TYPE_MAP + "', '" + EventCard.ACTION_TYPE_SESSION + "')", new String[] { currentTime, currentTime }, ScheduleContract.Cards.CARD_ID);
            break;
    }
    return loader;

Example 4 with CursorLoader

use of android.content.CursorLoader in project iosched by google.

the class SessionDetailModelTest method createCursorLoader_TagMetadaQuery_ReturnsCursorLoader.

@Test
public void createCursorLoader_TagMetadaQuery_ReturnsCursorLoader() {

    SessionDetailModel spyModel = spy(new SessionDetailModel(mMockUri, mMockContext, mMockSessionsHelper, mMockLoaderManager));

    // When ran with mock uri and tag metadata query loader id
    CursorLoader createdCursorLoader = (CursorLoader) spyModel.createCursorLoader(SessionDetailModel.SessionDetailQueryEnum.TAG_METADATA, null);
    // Then the returned cursor loader is the mock cursor loader
