在我的应用程序中,我从库中上传图像,我想将此图像存储在SQLite数据库中.如何在数据库中存储位图？我正在将位图转换为字符串并将其保存在数据库中.从数据库中检索它时,我无法将该字符串分配给ImageView,因为它是一个字符串.

Imageupload12 .java:

 public class Imageupload12 extends Activity {
  Button buttonLoadImage;
  ImageView targetImage;
  int i = 0;
  Database database = new Database(this);
  String i1;
  String img;
  @Override
  public void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.main5);
   buttonLoadImage = (Button) findViewById(R.id.loadimage);
   targetImage = (ImageView) findViewById(R.id.targetimage);


   Bundle b = getIntent().getExtras();
   if (b != null) {
    img = b.getString("image");
    targetImage2.setImageURI("image");
    //i am getting error as i cant assign string to imageview.

   }

   buttonLoadImage.setOnClickListener(new Button.OnClickListener() {

    public void onClick(View arg0) {
     // TODO Auto-generated method stub …

我在一个包含纬度和经度对的文本文件中有一个JSON数据,现在我想将这些数据存储到MYSQL DB中,如何进行以及最好的方法请建议.

这是我的JSON数据
