CodePudding user response:
DBopenHelper data in name only the relative path, but you can customize a ContextWrapper to handle your path,
Public class DatabaseContext extends ContextWrapper {
Public DatabaseContext Context (base) {
Super (base);
}
@ Override
The public File getDatabasePath (String name) {
If (name. StartsWith (Environment. External.getexternalstoragedirectory () getAbsolutePath ())) {
//begin with sd card, your processing
} else {
//your processing
}
Return super. GetDatabasePath (name);
}
@ Override
Public SQLiteDatabase openOrCreateDatabase (String name, int mode,
SQLiteDatabase. CursorFactory factory,
DatabaseErrorHandler errorHandler) {
Return openOrCreateDatabase (name, mode, the factory);
}
@ Override
Public SQLiteDatabase openOrCreateDatabase (String name, int mode,
SQLiteDatabase. CursorFactory factory) {
Return SQLiteDatabase. OpenOrCreateDatabase (
GetDatabasePath (name), null);
}
}
Custom Sqlite nHelper, take the context into custom
*/
Public class CustomDbHelper extends SQLiteOpenHelper {
Public CustomDbHelper (Context Context, String name, SQLiteDatabase. CursorFactory factory, int version) {
Super (new DatabaseContext (context), name, factory, version);
}
.
}
It is important to note that if you use the sd card database, memory card should be well dealt with
