I'm using Activitygroup concept to handle multiple activities under single tab. What I am doing in first activity of tab, I fetch image from gallery and camera, and after that when user selects image that image should move to second activity but those both activities must remain under the same tab. Here is my code...
TabGroupActivity.java
public class TabGroupActivity extends ActivityGroup {
private ArrayList<String> mIdList;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (mIdList == null) mIdList = new ArrayList<String>();
}
@Override
public void finishFromChild(Activity child) {
LocalActivityManager manager = getLocalActivityManager();
int index = mIdList.size()-1;
if (index < 1) {
finish();
return;
}
manager.destroyActivity(mIdList.get(index), true);
mIdList.remove(index); index--;
String lastId = mIdList.get(index);
Intent lastIntent = manager.getActivity(lastId).getIntent();
Window newWindow = manager.startActivity(lastId, lastIntent);
setContentView(newWindow.getDecorView());
}
public void startChildActivity(String Id, Intent intent) {
Window window = getLocalActivityManager().startActivity(Id,intent.addFlags(Intent.FLAG_ACTIVITY_BROUGHT_TO_FRONT));
if (window != null) {
mIdList.add(Id);
setContentView(window.getDecorView());
}
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
//preventing default implementation previous to android.os.Build.VERSION_CODES.ECLAIR
return true;
}
return super.onKeyDown(keyCode, event);
}
@Override
public boolean onKeyUp(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
onBackPressed();
return true;
}
return super.onKeyUp(keyCode, event);
}
public void onBackPressed() {
int length = mIdList.size();
if ( length > 1) {
Activity current = getLocalActivityManager().getActivity(mIdList.get(length-1));
current.finish();
}
}
}
MainActivity.java
Intent intentPics = new Intent().setClass(this, GalleryPic_First.class);
TabSpec tabPics = tabHost
.newTabSpec("Photo")
.setIndicator("Photo", ressources.getDrawable(R.drawable.icon_apple_config))
.setContent(intentPics);
GalleryPic_First .java
public class GalleryPic_First extends TabGroupActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
startChildActivity("EditActivity", new Intent(this,GalleryPic.class));
}
}
GalleryPic.java
public class GalleryPic extends Activity {
private static final int TAKE_PICTURE = 0;
private static final int REQUEST_ID = 1;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

ivGallery.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setAction(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
getParent().startActivityForResult(intent, REQUEST_ID);
}
});
ivCamera.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent("android.media.action.IMAGE_CAPTURE");
File f = new File(Environment.getExternalStorageDirectory(), "photo.jpg");
i.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
mUri = Uri.fromFile(f);
getParent().startActivityForResult(i, TAKE_PICTURE);
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case TAKE_PICTURE:
if (resultCode == Activity.RESULT_OK && data != null)
{
getContentResolver().notifyChange(mUri, null);
ContentResolver cr = getContentResolver();
try
{
mPhoto = android.provider.MediaStore.Images.Media.getBitmap(cr, mUri);
GalleryPic_Second.bmp = mPhoto;
}
catch (Exception e)
{
Toast.makeText(this, e.getMessage(), Toast.LENGTH_SHORT).show();
}
}
break;
case REQUEST_ID :
InputStream stream = null;
if (resultCode == Activity.RESULT_OK && data != null) {
try
{
stream = getContentResolver().openInputStream(data.getData());
Bitmap original = BitmapFactory.decodeStream(stream);
GalleryPic_Second.bmp = Bitmap.createScaledBitmap(original, original.getWidth()/HALF, original.getHeight()/HALF, true);
Intent in = new Intent(GalleryPic.this, GalleryPic_Second.class);
TabGroupActivity parent = (TabGroupActivity)getParent();
parent.startChildActivity("ArrowsActivity", in);
}
catch (Exception e)
{
e.printStackTrace();
}
if (stream != null) {
try {
stream.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
break;
}
}
@Override
public void onBackPressed() {
// this.getParent().onBackPressed();
TabViewLayout parentTab = (TabViewLayout) this.getParent();
parentTab.switchTabBar(1);
}
}
GalleryPic_Second.java
public class GalleryPic_Second extends Activity {
public static Bitmap bmp;
Button btnUpload;
ImageView iv;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.transparent_dialog);
View viewToLoad = LayoutInflater.from(this.getParent()).inflate(R.layout.transparent_dialog, null);
this.setContentView(viewToLoad);
setResult(RESULT_OK);
iv = (ImageView)viewToLoad.findViewById(R.id.photo_holder);
btnUpload = (Button)viewToLoad.findViewById(R.id.upload);
iv.setImageBitmap(bmp);
btnUpload.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
finish();
}
});
}
@Override
public void onBackPressed() {
// this.getParent().onBackPressed();
finish();
}
public void onActivityResult(int reqCode, int resultCode, Intent data) {
super.onActivityResult(reqCode, resultCode, data);
}
}
But the image is not being displayed in second activity. How to do this?
