android – 将图像保存到SQLITE中?

我应该使用哪种数据类型在sqlLite数据库表中存储图像?

以下是我的尝试:

@Override
public void onCreate(SQLiteDatabase db) {
    // TODO Auto-generated method stub
    db.execSQL("CREATE TABLE" + MP_TABLE_NAME + " ( " +
            BaseColumns._ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
            " NAME TEXT, " +
            " LAT REAL, "+
            " LNG REAL,"+
            ");"
              );

}

解决方法:

尝试这个..

使用BLOB列创建表:

CREATE TABLE storedImages (_id INTEGER PRIMARY KEY, myImage BLOB);

使用HTTP下载图像并将其存储在表中:

DefaultHttpClient mHttpClient = new DefaultHttpClient();  
HttpGet mHttpGet = new HttpGet("your image url");  
HttpResponse mHttpResponse = mHttpClient.execute(mHttpGet);  
if (mHttpResponse.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {  
    HttpEntity entity = mHttpResponse.getEntity();  
    if (entity != null) {  
        // insert to database  
        ContentValues values = new ContentValues();  
        values.put(MyBaseColumn.MyTable.ImageField, EntityUtils.toByteArray(entity));  
        getContentResolver().insert(MyBaseColumn.MyTable.CONTENT_URI, values);  
    }
 }

将BLOB加载到ImageView中:

 ImageView myImage = (ImageView) findViewById(R.id.myImage);
 byte[] bb = cursor.getBlob(cursor.getColumnIndex(MyBaseColumn.MyTable.ImageField));
 myImage.setImageBitmap(BitmapFactory.decodeByteArray(bb, 0, bb.length));
