import android.app.Activity; 
import android.content.Intent; 
import android.graphics.Bitmap; 
import android.graphics.BitmapFactory; 
import android.os.Bundle; 
import android.util.Log; 
import android.view.View; 
import android.widget.Button; 
import android.widget.ListView; 

public class SQLiteDemoActivity extends Activity { 
private static final int SELECT_PICTURE = 1; 
ArrayList<Contact> imageArry = new ArrayList<Contact>(); 
ContactImageAdapter adapter; 
Button BrowseButton; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.main); 

DataBaseHandler db = new DataBaseHandler(this); 
//get image from drawable 
Bitmap image = BitmapFactory.decodeResource(getResources(), 
R.drawable.facebook); 


BrowseButton=(Button)findViewById(R.id.BrowseButton); 



BrowseButton.setOnClickListener(new View.OnClickListener() { 

@Override 
public void onClick(View v) { 
    // TODO Auto-generated method stub 
    // in onCreate or any event where your want the user to 
    // select a file 
    Intent intent = new Intent(); 
    intent.setType("image/*"); 
    intent.setAction(Intent.ACTION_GET_CONTENT); 
    startActivityForResult(Intent.createChooser(intent, 
      "Select Picture"), SELECT_PICTURE); 

} 
}); 




//convert bitmap to byte 
ByteArrayOutputStream stream = new ByteArrayOutputStream(); 
image.compress(Bitmap.CompressFormat.JPEG, 100, stream); 
byte imageInByte[] = stream.toByteArray(); 
/** 
* CRUD Operations 
* */ 
//Inserting Contacts 
Log.d("Insert: ", "Inserting .."); 
db.addContact(new Contact("FaceBook", imageInByte)); 
//display main List view bcard and contact name 

//Reading all contacts from database 
List<Contact> contacts = db.getAllContacts(); 
for (Contact cn : contacts) { 
String log = "ID:" + cn.getID() + " Name: " + cn.getName() 
+ " ,Image: " + cn.getImage(); 

//Writing Contacts to log 
Log.d("Result: ", log); 
//add contacts data in arrayList 
imageArry.add(cn); 

} 
adapter = new ContactImageAdapter(this, R.layout.screen_list, 
imageArry); 
ListView dataList = (ListView) findViewById(R.id.list); 
dataList.setAdapter(adapter); 
} 
}

請勿嘗試將圖像保存到數據庫中。將這些圖像保存到您的外部存儲並將其路徑保存到數據庫中。
