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();
}
}
}

But the image is not being displayed in second activity. How to do this?
call this way

I am cropping an image from the gallery but cannot able to set that cropped image in imageView, final image set as default image I mean without cropped so how to set Cropped image in ImageView
this is image Picker from gallery
newPostImg.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
galIntent=new Intent(Intent.ACTION_PICK,MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(Intent.createChooser(galIntent,"select image"),2);
}
});
This is for crop image
private void CropImage() {
try {
CropIntent = new Intent("com.android.camera.action.CROP");
CropIntent.setDataAndType(postImageUri,"image/*");
CropIntent.putExtra("crop","true");
CropIntent.putExtra("outputX",180);
CropIntent.putExtra("outputY",180);
CropIntent.putExtra("aspectX",3);
CropIntent.putExtra("aspectY",4);
CropIntent.putExtra("scaleUpIfNeeded",true);
CropIntent.putExtra("return-data",true);
startActivityForResult(CropIntent,1);
}
catch (ActivityNotFoundException ex)
{
}
}
This is onActivityResult
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 0&&resultCode ==RESULT_OK)
CropImage();
if (requestCode==2){
if (data!=null){
postImageUri=data.getData();
CropImage();
newPostImg.setImageURI(postImageUri);
}
}
}
And this is my permission
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA"/>
and this is imageView xml
<ImageView
android:layout_margin="10dp"
android:id="#+id/newPostImg"
android:layout_width="match_parent"
android:layout_height="250dp"
android:src="#drawable/default1" />
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == 2) {
if (data != null) {
postImageUri = data.getData();
CropImage();
}
} else if (requestCode == 1) {
Bundle extras = data.getExtras();
Bitmap bitmap= extras.getParcelable("data");
newPostImg.setImageBitmap(bitmap);
}
}
}
}
You should set Image on CropIntent's result and not on cameraIntent's result.
Uri imageUri = Uri.parse(mCurrentPhotoPath);
Intent intent = new Intent(mContext, Crop_Activity.class);
intent.putExtra("imageUri", imageUri.toString());
startActivityForResult(intent, 105);
Here is the code for crop activity
public class Crop_Activity extends BaseActivity implements CropImageView.OnSetImageUriCompleteListener, CropImageView.OnCropImageCompleteListener, View.OnClickListener {
private CropImageView mCropImageView;
private ProgressDialog dialog;
int type;
private Uri imageUri;
private Bitmap cropped;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.crop_activity);
setScreenName("Crop Image screen");
Bundle extras = getIntent().getExtras();
if (extras != null) {
imageUri = Uri.parse(getIntent().getStringExtra("imageUri"));
}
//====Initialize Here====//
init();
//====Set CropImageView Here====//
setCropImageView();
}
void init() {
dialog = new ProgressDialog(Crop_Activity.this);
dialog.setCancelable(false);
dialog.setMessage("Cropping Image...");

I have created a fragment which a button and an image view in it. on button click the camera opens when I take a picture then I want that picture to appear in the imageView.
how can I activate this task?
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
View rootview = inflater.inflate(R.layout.fragment_new_visitor, container, false);
capture=rootview.findViewById(R.id.capture);
capture.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent intent = new Intent("android.media.action.IMAGE_CAPTURE");
startActivity(intent);
}
});
return rootview;
please help
Just try this one,
Declare this before on create method
private final int requestCode = 20;
inside onclick event, do this
Intent photoCaptureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(photoCaptureIntent, requestCode);
then override oncreate method
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(this.requestCode == requestCode && resultCode == RESULT_OK){
Bitmap bitmap = (Bitmap)data.getExtras().get("data");
imageview.setImageBitmap(bitmap);
}
}
public class BlankFragment extends Fragment {

private Uri realUri;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment

}
#Override

btnGallery = (Button)getView().findViewById(R.id.btnGallery);
btnCamera = (Button)getView().findViewById(R.id.btnCamera);

I tried using a "speech to text" feature in my app.
it opens up the recording window/ dialog or whatever but the text doesn't show.
this is the code:
public void onTalk(View v){
promptSpeechInput();
}
public void promptSpeechInput()
{
Intent i=new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
i.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
i.putExtra(RecognizerIntent.EXTRA_PROMPT,"say something");
try{
startActivityForResult(i, 50);
}
catch(ActivityNotFoundException e){
Toast.makeText(this,"sorry your device doesnt support speech language",Toast.LENGTH_LONG).show();
}
}
then there's the onResult part:
public void onActivityResult(int request_code, int result_code, Intent i){
super.onActivityResult(request_code,result_code,i);
if (request_code==RESULT_OK)
if(i!=null) {
EditText locationTS = (EditText) findViewById (R.id.locationET);
ArrayList<String> result = i.getStringArrayListExtra((RecognizerIntent.EXTRA_RESULTS));
locationTS.setText(result.get(0));
}
}
locationTS is an EditText, and it does not show any text after i talk.
This worked in my case:
I had a separate Helper class as:
public class SpeechRecognitionHelper {
private static final int VOICE_RECOGNITION_REQUEST_CODE=101;
public static void run(Activity activity){
if(isSpeechRecognitionActivityPresent(activity)){
startRecognition(activity);
}
else {
Toast.makeText(activity,"You must install Google Voice Search",Toast.LENGTH_LONG).show();
installGoogleVoiceSearch(activity);
}
}
private static boolean isSpeechRecognitionActivityPresent(Activity activity){
try {
PackageManager packageManager = activity.getPackageManager();
List activities = packageManager.queryIntentActivities(new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH),0);
if (activities.size()!=0){
return true;
}
}
catch (Exception e){
}
return false;
}
public static void startRecognition(Activity activity){
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
intent.putExtra(RecognizerIntent.EXTRA_PROMPT,"Say Something");
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,1);
activity.startActivityForResult(intent,VOICE_RECOGNITION_REQUEST_CODE);
}
private static void installGoogleVoiceSearch(final Activity activity){
Dialog dialog = new AlertDialog.Builder(activity)
.setMessage("For recognition Install Google Voice Search")
.setTitle("Install voice search?")
.setPositiveButton("Install", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=com.google.android.voicesearch"));
intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY | Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
activity.startActivity(intent);
}
})
.setNegativeButton("Cancel", null)
.create();
dialog.show();
}
}
Then in the MainActivity:
public class MainActivity extends AppCompatActivity implements View.OnClickListener{
private static final int VOICE_RECOGNITION_REQUEST_CODE=101;
private static final int CAMERA_REQUEST=201;
private Button buttonVoiceCommand;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
buttonVoiceCommand = (Button)findViewById(R.id.buttonVoiceCommand);
buttonVoiceCommand.setOnClickListener(this);
}
#Override
public void onClick(View view) {
int id = view.getId();
if (id == R.id.buttonVoiceCommand){
run(MainActivity.this);
}
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data){
super.onActivityResult(requestCode,resultCode,data);
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE && resultCode == RESULT_OK) {
ArrayList<String> matches = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
if(matches.size()>0){
if(matches.get(0).indexOf("camera")>0){
Intent cameraIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent,CAMERA_REQUEST);
}
else {
Toast.makeText(this,matches.get(0),Toast.LENGTH_LONG).show();
}
}
}
if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
//Perform whatever you want to do (-.-)
Toast.makeText(this,"Camera Working",Toast.LENGTH_LONG).show();
}
}
}
I Toast the content of matches.get(0) You just have to set it in an edit text
I have a ProgressDialog, and I want to do something when the dialog dissappears (but I do not want put my action after the progressdialog.dismiss).
Is it possible to:
----> if No ---> Do something
Check if dialog is showing
----> if Yes
/|\ |
| \|/
--------------------- Wait
Don't think to difficult, I just want to perform an action, but only if there is no dialog, and if there is one, to perform the action when the dialog is done.
Thank you!

Try this,
private void doSomethingWhenProgressNotShown() {
if (mProgressDialog != null && mProgressDialog.isShowing()) {
//is running
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
doSomethingWhenProgressNotShown();
}
}, 500);
}
//isnt running- do something here
}
I think you can use this code:
if (mProgressDialog != null && mProgressDialog.isShowing()) {
//is running
}
//isnt running
Or you can set listeners:
mProgressDialog.setOnCancelListener(listener);
mProgressDialog.setOnDismissListener(listener);
I have two activities which starts the same sub-activity for result.
But in only one of them onActivityResult works.
Here are parts of my code
This is my first Activity. As you can see it calls NewCommentActivity in startActivityForResult and this part works fine
public class OfferActivity extends ListActivity implements View.OnClickListener {
...
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.offer_menu_comment:
Intent commentIntent = new Intent(this, NewCommentActivity.class);
commentIntent.putExtra(Offer.OFFER, offer);
startActivityForResult(commentIntent, COMMENT_REQUEST_CODE);
return true;
...
default:
return super.onOptionsItemSelected(item);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case COMMENT_REQUEST_CODE:
if (resultCode == RESULT_OK) {
Integer commentCnt = offer.getCommentCnt() + 1;
offer.setCommentCnt(commentCnt);
commentButton.setText(getString(R.string.offer_comments, offer.getCommentCnt()));
}
break;
}
}
...
}
Here is my second activity which calls NewCommentActivity too, but here onActivityResult is not called
public class CommentsActivity extends ListActivity{
...
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
...
case COMMENT_ITEM_ID:
Intent commentIntent = new Intent(this, NewCommentActivity.class);
commentIntent.putExtra(Offer.OFFER, offer);
startActivityForResult(commentIntent, COMMENT_REQUEST_CODE);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case COMMENT_REQUEST_CODE:
if (resultCode == RESULT_OK) {
Integer commentCnt = offer.getCommentCnt() + 1;
offer.setCommentCnt(commentCnt);
Comment comment = data.getParcelableExtra(Comment.COMMENT);
commentImageListAdapter.addItemAtFront(comment);
}
break;
}
}
...
}
And here is code for NewCommentActivity :
public class NewCommentActivity extends Activity implements View.OnClickListener {
private static final String TAG = "Gift/NewCommentActivity";
private Offer offer;
private EditText editText;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_comment);
offer = getIntent().getParcelableExtra(Offer.OFFER);
editText = (EditText) findViewById(R.id.new_comment_text);
Button button = (Button) findViewById(R.id.new_comment_button);
button.setOnClickListener(this);
}
#Override
public void onClick(View view) {
if (editText.getText().length() > 0) {
new AddCommentAsyncTask().execute(offer, editText.getText().toString());
}
}
private class AddCommentAsyncTask extends AsyncTask<Object, Void, Comment> {
private String errorString;
private ProgressDialog progressDialog;
#Override
protected Comment doInBackground(Object... objects) {
Offer offer = (Offer) objects[0];
String text = (String) objects[1];
Comment comment = null;
try {
comment = ServiceContainer.getService().addComment(offer, text);
} catch (OfferException e) {
Log.e(TAG, "exception in comment", e);
int id;
if ((id = e.getErrorStringId()) != -1) {
errorString = getString(id);
} else {
errorString = e.getLocalizedMessage();
}
cancel(false);
}
return comment;
}
#Override
protected void onPreExecute() {
progressDialog = Utils.newSpinnerDialog(NewCommentActivity.this, R.string.sending);
}
#Override
protected void onCancelled() {
progressDialog.dismiss();
AlertDialog.Builder builder = Utils.newAlertDialog(NewCommentActivity.this, errorString, true);
builder.setPositiveButton(R.string.dialog_ok, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
new AddCommentAsyncTask().execute(offer, editText.getText().toString());
}
})
.setNegativeButton(R.string.dialog_cancel, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
setResult(RESULT_CANCELED);
finish();
}
})
.create()
.show();
}
#Override
protected void onPostExecute(Comment comment) {
progressDialog.dismiss();
Intent intent = new Intent();
intent.putExtra(Comment.COMMENT, comment);
setResult(RESULT_OK, intent);
finish();
}
}
And finally AndroidManifest for all activities:
<activity android:name=".activity.OfferActivity"
android:configChanges="orientation"/>
<activity android:name=".activity.CommentsActivity"
android:configChanges="orientation"
android:label="#string/comment_activity_title"/>
<activity android:name=".activity.NewCommentActivity"
android:windowSoftInputMode="adjustResize"
android:configChanges="orientation"
android:label="#string/new_comment_activity_title"/>
</application>
Please help me.
Thanks.
