Choose a contact and fill it in EditText

I develop an app in android and I want when to press a button opens the contacts and choose one name and fill that name in EditText .. just like the SMS message.
here my code it just open the contact and when I choose the name it's going nowhere!
addto.setOnClickListener(new View.OnClickListener() {
private static final int PICK_CONTACT = 0;
#Override
public void onClick(View v) {
Intent it= new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
startActivityForResult(it, PICK_CONTACT);
}
});

You can get contact information in onActivityResult() method inside your activity.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch (requestCode) {
case PICK_CONTACT:
Uri contactData = data.getData();
Cursor cursor = managedQuery(contactData, null, null, null, null);
cursor.moveToFirst();
//Get number and name from cursor
String number = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Phone.NUMBER));
String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
//set number and name in editext
etName.setText(contactName);
etNumber.setText(number);
break;
}
}
}

how can i delete a contact after choosing it in my intent android

How can I delete a contact after choosing it in my intent android?
I tried searching but I couldn't find anything, thanks in advance!
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
if (intent.resolveActivity(getPackageManager()) !=null)
startActivityForResult(intent, 1);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode==1 && resultCode==RESULT_OK){
Uri contactUri = data.getData();
}
}

You have to use ContentResolver & Cursor Query to delete particular contact.Below Usage :
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
try
{
cr.delete(contactUri, null, null);
}
catch(Exception e)
{
System.out.println(e.getStackTrace());
}
}

Get all the images from the Gallery in Android

I want to make my own Gallery in Android but I can´t find the way to bring all the photos without selecting them. I have tried this:
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
But opens an intent in which I have to select one or more photos. Is there a way I can bring them all without selecting them?

This is a sample code for it
public class GetImageActivity extends Activity {
private static final int SELECT_PICTURE = 1;
private String selectedImagePath;
private ImageView img;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
img = (ImageView)findViewById(R.id.ImageView01);
((Button) findViewById(R.id.Button01))
.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), SELECT_PICTURE);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == SELECT_PICTURE) {
Uri selectedImageUri = data.getData();
selectedImagePath = getPath(selectedImageUri);
System.out.println("Image Path : " + selectedImagePath);
img.setImageURI(selectedImageUri);
}
}
}
public String getPath(Uri uri) {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
return cursor.getString(column_index);
}
}

How to get group of contacts list from Phone Contacts

btngal.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent i=new Intent(Intent.ACTION_PICK,android.provider.ContactsContract.Contacts.CONTENT_GROUP_URI);
startActivityForResult(i,0);
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// super.onActivityResult(requestCode, resultCode, data);
if (resultCode != RESULT_CANCELED) {
if (requestCode == 0) {
Uri selectContact=data.getData();
String[] filePathColumn={Contacts.CONTENT_URI.toString()};
Cursor cursor = getContentResolver().query(selectContact,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
filePath = cursor.getString(columnIndex);
cursor.close();
}
}
}
While doing this action I am getting below error:
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.PICK dat=content://com.android.contacts/contacts/group }

In order to read contacts from native android app, you need permission, like this in your manifest.xml
<uses-permission android:name="android.permission.READ_CONTACTS"/>
Make sure you have that one.

Get image Uri in onActivityResult after taking photo?

I have this code:
startActivityForResult(new Intent(MediaStore.ACTION_IMAGE_CAPTURE), CAMERA_IMAGE);
That allows that user to take a photo. Now how would I get the Uri of that photo in onActivityResult? Is it an Intent extra? Is it through Intent.getData()?

protected void onActivityResult(int requestCode, int resultCode, Intent intent){
Uri u = intent.getData();
}
By the way... there's a bug with that intent in some devices. Take a look at this answer to know how to workaround it.

Instead of just launching the intent, also make sure to tell the intent where you want the photo.
Uri uri = Uri.parse("file://somewhere_that_you_choose");
Intent photoIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
photoIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
startActivityForResult(photoIntent, CAMERA_IMAGE);
Then when you get your onActivityResult() method called, if it was a success just open a stream to the URI and it should all be set.

Uri uri = null;
if(requestCode == GALLERY_INTENT && resultCode == RESULT_OK){
uri = data.getData();
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
Bitmap photo = (Bitmap) data.getExtras().get("data");
Uri fileUri = Utils.getUri(getActivity(), photo);
}
}
public String getRealPathFromURI (Uri contentUri) {
String path = null;
String[] proj = { MediaStore.MediaColumns.DATA };
Cursor cursor = getActivity().getContentResolver().query(contentUri, proj, null, null, null);
if (cursor.moveToFirst()) {
int column_index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
path = cursor.getString(column_index);
}
cursor.close();
return path;
}
