How I can Android Save Image And Get Image From Sqlite Database I'm Using Android Studio ?

解决方案

Instead working with Contact for example, you can implement this way

public class Image{

String imagePath; //it is your absolute image file path

}

And your DatabaseHandler can be implemented like below

public class DatabaseHandler extends SQLiteOpenHelper {

// All Static variables

// Database Version

private static final int DATABASE_VERSION = 1;

// Database Name

private static final String DATABASE_NAME = "imagedb";

// Contacts table name

private static final String TABLE_IMAGE = "images";

// Contacts Table Columns names

private static final String KEY_ID = "id";

private static final String KEY_IMAGE_PATH = "name";

public DatabaseHandler(Context context) {

super(context, DATABASE_NAME, null, DATABASE_VERSION);

}

// Creating Tables

@Override

public void onCreate(SQLiteDatabase db) {

String sqlQuery = "CREATE TABLE " + TABLE_IMAGE + "("

+ KEY_ID + " INTEGER PRIMARY KEY," + KEY_IMAGE_PATH + " TEXT)";

db.execSQL(sqlQuery);

}

// Upgrading database

@Override

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

// Drop older table if existed

db.execSQL("DROP TABLE IF EXISTS " + TABLE_IMAGE);

// Create tables again

onCreate(db);

}

// Adding new image

public void addImage(Image image) {

SQLiteDatabase db = this.getWritableDatabase();

ContentValues values = new ContentValues();

values.put(KEY_IMAGE_PATH, image.imagePath); // Image path

// Inserting Row

db.insert(TABLE_IMAGE, null, values);

db.close(); // Closing database connection

}

// Getting single image

public Image getImage(int id) {

SQLiteDatabase db = this.getReadableDatabase();

Cursor cursor = db.query(TABLE_IMAGE, new String[] { KEY_ID,

KEY_IMAGE_PATH}, KEY_ID + "=?",

new String[] { String.valueOf(id) }, null, null, null, null);

if (cursor != null)

cursor.moveToFirst();

Image image = new Image(Integer.parseInt(cursor.getString(0)),

cursor.getString(1));

// return image

return image;

}

}
