Columns

class Columns : BaseColumns
kotlin.Any
   ↳ androidx.core.provider.FontsContractCompat.Columns

Defines the constants used in a response from a Font Provider. The cursor returned from the query should have the ID column populated with the content uri ID for the resulting font. This should point to a real file or shared memory, as the client will mmap the given file descriptor. Pipes, sockets and other non-mmap-able file descriptors will fail to load in the client application.

Constants

FILE_ID

static val FILE_ID: String

Constant used to request data from a font provider. The cursor returned from the query may populate this column with a long for the font file ID. The client will request a file descriptor to "file/FILE_ID" with this ID immediately under the top-level content URI. If not present, the client will request a file descriptor to the top-level URI with the given base font ID. Note that several results may return the same file ID, e.g. for TTC files with different indices.

Value: "file_id"

TTC_INDEX

static val TTC_INDEX: String

Constant used to request data from a font provider. The cursor returned from the query should have this column populated with an int for the ttc index for the resulting font.

Value: android.provider.FontsContract.Columns.TTC_INDEX

VARIATION_SETTINGS

static val VARIATION_SETTINGS: String

Constant used to request data from a font provider. The cursor returned from the query may populate this column with the font variation settings String information for the font.

Value: android.provider.FontsContract.Columns.VARIATION_SETTINGS

WEIGHT

static val WEIGHT: String

Constant used to request data from a font provider. The cursor returned from the query should have this column populated with the int weight for the resulting font. This value should be between 100 and 900. The most common values are 400 for regular weight and 700 for bold weight.

Value: android.provider.FontsContract.Columns.WEIGHT

ITALIC

static val ITALIC: String

Constant used to request data from a font provider. The cursor returned from the query should have this column populated with the int italic for the resulting font. This should be 0 for regular style and 1 for italic.

Value: android.provider.FontsContract.Columns.ITALIC

RESULT_CODE

static val RESULT_CODE: String

Constant used to request data from a font provider. The cursor returned from the query should have this column populated to indicate the result status of the query. This will be checked before any other data in the cursor. Possible values are RESULT_CODE_OK, RESULT_CODE_FONT_NOT_FOUND, RESULT_CODE_MALFORMED_QUERY and RESULT_CODE_FONT_UNAVAILABLE. If not present, RESULT_CODE_OK will be assumed.

Value: android.provider.FontsContract.Columns.RESULT_CODE

RESULT_CODE_OK

static val RESULT_CODE_OK: Int

Constant used to represent a result was retrieved successfully. The given fonts will be attempted to retrieve immediately via android.content.ContentProvider#openFile(Uri, String). See RESULT_CODE.

Value: android.provider.FontsContract.Columns.RESULT_CODE_OK

RESULT_CODE_FONT_NOT_FOUND

static val RESULT_CODE_FONT_NOT_FOUND: Int

Constant used to represent a result was not found. See RESULT_CODE.

Value: android.provider.FontsContract.Columns.RESULT_CODE_FONT_NOT_FOUND

RESULT_CODE_FONT_UNAVAILABLE

static val RESULT_CODE_FONT_UNAVAILABLE: Int

Constant used to represent a result was found, but cannot be provided at this moment. Use this to indicate, for example, that a font needs to be fetched from the network. See RESULT_CODE.

Value: android.provider.FontsContract.Columns.RESULT_CODE_FONT_UNAVAILABLE

RESULT_CODE_MALFORMED_QUERY

static val RESULT_CODE_MALFORMED_QUERY: Int

Constant used to represent that the query was not in a supported format by the provider. See RESULT_CODE.

Value: android.provider.FontsContract.Columns.RESULT_CODE_MALFORMED_QUERY
