Show a ProgressBar while saving/showing a SQLite database

Show a ProgressBar while saving/showing a SQLite database - android

I am new to Android development.
I am trying to complete my application, this app is saving data into a SQLite database, showing, updating, deleting, etc. But when I try to show all rows from database, this takes too much time. I want to add a ProgressBar to show users that it's taking its time.
Where in this code can I add a ProgressBar?
This is MainActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Instantiate database handler
db=new DatabaseHandler(this);
lv = (ListView) findViewById(R.id.list1);
pic = (ImageView) findViewById(R.id.pic);
nazev =(EditText) findViewById(R.id.nazev);
objem =(EditText) findViewById(R.id.objem);
obsah_alkoholu =(EditText) findViewById(R.id.obsah_alkoholu);
aroma =(EditText) findViewById(R.id.aroma);
chut =(EditText) findViewById(R.id.chut);
dokonceni =(EditText) findViewById(R.id.dokonceni);
poznamka =(EditText) findViewById(R.id.poznamka);
vsechnyradky =(TextView) findViewById(R.id.textView);
ShowRecords();
}
public void buttonClicked(View v){
int id=v.getId();
switch(id){
case R.id.save:
if(nazev.getText().toString().trim().equals("")){
Toast.makeText(getApplicationContext(),"Není název.", Toast.LENGTH_LONG).show();
} else{
addRumy();
}
ShowRecords();
break;
case R.id.display:
ShowRecords();
break;
case R.id.pic:
selectImage();
break;
}
}
public void selectImage(){
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, 2);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(requestCode) {
case 2:
if(resultCode == RESULT_OK){
Uri choosenImage = data.getData();
if(choosenImage !=null){
bp=decodeUri(choosenImage, 400);
pic.setImageBitmap(bp);
}
}
}
}
//COnvert and resize our image to 400dp for faster uploading our images to DB
protected Bitmap decodeUri(Uri selectedImage, int REQUIRED_SIZE) {
try {
// Decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o);
// The new size we want to scale to
// final int REQUIRED_SIZE = size;
// Find the correct scale value. It should be the power of 2.
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp / 2 < REQUIRED_SIZE
|| height_tmp / 2 < REQUIRED_SIZE) {

}
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
// Decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(getContentResolver().openInputStream(selectedImage), null, o2);
}
catch (Exception e){

return null;

//Convert bitmap to bytes

Error

use this
ProgressDialog pDialog = new ProgressDialog(this);
pDialog.setMessage("please wait...");
pDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pDialog.setCancelable(false);
pDialog.show();
and after data load dismiss the progress dialog
pDialog.dismiss();

Use an asyncTask for ShowRecords() and override the OnProgressUpdate method
#Override
protected void onProgressUpdate(Integer... values) {
// use the values to update your progress bar
}
your ShowRecords should look like this
private void ShowRecords() {
final ProgressDialog pDialog = new ProgressDialog(this);
pDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pDialog.setCancelable(false);
new AsyncTask<Object,Integer,ArrayList<Rumy>>() {
#Override
protected ArrayList<Rumy> doInBackground(Object[] params) {
ArrayList<Rumy> rumy = db.getAllRumy();
return rumy;
}
#Override
protected void onProgressUpdate(Integer... values) {
pDialog.setMessage("please wait..."+ values[0]);
pDialog.show();
}
#Override
protected void onPostExecute(ArrayList<Rumy> list) {
data=new DataAdapter(this,list);
lv.setAdapter(list);
//lv.setOnItemClickListener can be put here
}
}.execute();
}

When your function showRecords() is calling in the next line set progress bar visible and when the function is fully executed make progress bar gone.
I guess u know how to add progress bar because u didn't mention how to use it so.

Use onActivityResult

I try to get an image what i pick in my gallery.
I cast startActivityForResult because my class not extendess an Activity and i need use onActivityResult for set imageview with the selected image.
My code...
Intent getIntent = new Intent(Intent.ACTION_GET_CONTENT);
getIntent.setType("image/*");
Intent pickIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
pickIntent.setType("image/*");
Intent chooserIntent = Intent.createChooser(getIntent, "Elegir imagen");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[]{pickIntent});
((Activity)context).startActivityForResult(chooserIntent, INTENT_ELEGIR_IMAGEN);
My onActivityResult
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
if (resultCode == Activity.RESULT_OK) {
switch (requestCode) {
case INTENT_ELEGIR_IMAGEN:
Uri selectedImageUri = data.getData();
if(selectedImageUri !=null) {
try {
fotoJugador.setImageBitmap(decodeUri(selectedImageUri));
imageSelected = true;
} catch (FileNotFoundException e) {
throw new RuntimeException(e);
} catch (IOException e) {
throw new RuntimeException(e);
}
}
break;
}
}
}
If dont have a solution, give a an advice please!!
Thanks!!!

In my activty i have a recyclerview and my cardview. In my cardview i have a overflowmenu, it has a 2 items: *Delete and *edit
When you click on edit, i create an dialog with the attributes to edit and one of this is an image. I have an imageview and when you click on it launch pick intent to pick an image in gallery. All at this poinr are OK, but i cant set imageview because i cant get the image that i pick.

First of all please ask for permission to access External/Internal Storage.
For picking a picture from gallery use below code.
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 0);
Your onActivityResult will be like:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 0 && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
fotoJugador.setImageBitmap(bitmap);
imageSelected = true;
} catch (IOException e) {
e.printStackTrace();
}
}
}
Remove onActivityResult(chooserIntent);from your code.
Run this and let me know if this works.

Multiple Selection in Alert Dialog

Good Day,
I created a method showDialog which will show an Alert Dialog and will list multiple data that I can select of. My problem is when I click OK, the next method (myMethod()) i want to call is not being called. Can someone help me with this? Here is my code:
private void showDialog(List<String> list) {
final CharSequence[] dialogList= list.toArray(new CharSequence[list.size()]);
final AlertDialog.Builder builderDialog = new AlertDialog.Builder(SharingActivity.this);
builderDialog.setTitle("Select Item");
int count = dialogList.length;
boolean[] is_checked = new boolean[count];
String result = "";
builderDialog.setMultiChoiceItems(dialogList, is_checked,
new DialogInterface.OnMultiChoiceClickListener() {
public void onClick(DialogInterface dialog,
int whichButton, boolean isChecked) {
}
});
builderDialog.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
ListView list = ((AlertDialog) dialog).getListView();
// make selected item in the comma seprated string
StringBuilder stringBuilder = new StringBuilder();
for (int i = 0; i < list.getCount(); i++) {
boolean checked = list.isItemChecked(i);
if (checked) {
if (stringBuilder.length() > 0) stringBuilder.append(",");
stringBuilder.append(list.getItemAtPosition(i));
}
}
myMethod(stringBuilder.toString()); //this is the method
}
});
builderDialog.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
((TextView) findViewById(R.id.text)).setText("Click here to open Dialog");
}
});
AlertDialog alert = builderDialog.create();
alert.show();
}
Here is myMethod:
private void myMethod(String stringFriend){
Bundle extras = getIntent().getExtras();
byte[] byteArray = extras.getByteArray("image");
Bitmap image = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length);
//Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.ic_launcher);
SharePhoto photo = new SharePhoto.Builder()
.setBitmap(image)
.setCaption("")
.build();
List<String> peopleIds = new ArrayList<String>();
peopleIds.add(stringFriend);
SharePhotoContent content = new SharePhotoContent.Builder()
.addPhoto(photo)
.setPeopleIds(peopleIds)
.build();
ShareApi.share(content, null);
}

Memory Leaks and GridView

I am using a GridView and universalimageloader (1.8.6) and seem to be encountering a memory leak - though maybe I am misinterpreting DDMS and MAT results? This is code I did not write, but it is pretty basic - we are showing a number of photos and allowing the user to select as many as they want and then storing those for future reference. The code seems to work fine, but in MAT "Leak Suspect" the GridView from below keeps on showing up, chewing upwards of 5 mb each time, even when I have called finish() on the Activity. From what I have read Android can keep the Activity in memory until it wants to release it (and have seen this with other Activities) but it never seems to want to release this one - even when I force GC. The "new thread" allocation looks a bit suspicious, but wouldn't that get dellocated with the calling Activity?
Probably just missing something obvious, but here is the code:
public class PhotoGalleryPickerActivity extends MyActivity {
private Boolean mMultiple = false;

The MAT results, run from Eclipse, look like this. It shows all the various calls I have made to this Activity, as though none of them have been actually released:
The normal memory for the application hangs around 11-15mb, but as you can see it is now at ~50mb, and grows each time I call the activity. If all the memory for the suspects was reclaimed I think I would be right where I should be:
Finally, could this be a result of running from Eclipse remotely to the device? I saw something similar with another control and was not able to replicate. Whereas I am definitely able to replicate this.
Thanks!

Just to wrap this one up, the issue was the new Thread(), which was holding onto the resources and specifically the GridView (at +4mb per hit). My final solution was to just get rid of the thread and looper, and just call the two methods directly in the init() of the Activity. I have no idea why it was coded into a looping thread to begin with, though I suspect it may have been to update the list of images on the fly (or cut and pasted code that was not really understood). Anyway seems to be working and the memory is being successfully garage collected. Thanks to #dharms you the help!

ListView Shows Recent Image taken from camera

In my code when i take image from camera it shows correctly in imageview. But when i take second image, both listview items shows same picture..Old picture replaces with new one..when i take third picture then all of three items show same result.and so on..Please can anyone solve my problem.

This is because in your getView() you do not consider the position. You always set the bitmap to image2 which is the most recent bitmap: holder.image.setImageBitmap(image2);
I think you misunderstood how get view works. The getView() method is called for each item in the list when you notifyDataSetChanged().
The solution is to keep reference to the different bitmaps in a list (or elsewhere.. i am just giving a possible solution),
List<Bitmap> images = new ArrayList<>();
When you get the image from the result, add it to the images list.
image2 = Bitmap.createScaledBitmap(thumbnail, imageWidth , imageHeight, true);
images.add(image2)
Finally, setImageBitmap based on the position of the item during getView()
holder.image.setImageBitmap(images.get(position));

I want to display the facebook wall stream in my application using graph api.
The wall stream consists of following things 1)profile picture
2)name ,posted message,posted image
3)Like,Comment options
I got the data from facebook graph api
https://graph.facebook.com/me/home?access_token="+accesstoken;
In this I got data of page1 and I used "paging" to get the data of second page and same for getting third page.
But when I tried to display the first page,because of more images I am getting
Bitmap size exceeds VM Budget error:Out of Memory error
I want to know, how the other facebook applications managing this issue,I observed that they are loading only less number of records at a time.How to do such things,if I got the data in pagewise?

They might be caching the records or posts and they display(load) records visible to the user at that instant. on how to do this, check out this sample application from developer.android.com ->
displaying-bitmaps Efficiently.

You should try to limit the size of the Bitmaps that you show close to the size of the image view so that you don't waste memory by having large images in memory when you actually want to show a lower resolution image. I usually use this function to resize an image file to a size closer to the one that I want.
// decodes image and scales it to reduce memory consumption
private Bitmap decodeFile(File f) {
try {
// decode image size
BitmapFactory.Options o = new BitmapFactory.Options();
o.inJustDecodeBounds = true;
BitmapFactory.decodeStream(new FileInputStream(f), null, o);
// Find the correct scale value. It should be the power of 2.
int width_tmp = o.outWidth, height_tmp = o.outHeight;
int scale = 1;
while (true) {
if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE)
break;
width_tmp /= 2;
height_tmp /= 2;
scale *= 2;
}
// decode with inSampleSize
BitmapFactory.Options o2 = new BitmapFactory.Options();
o2.inSampleSize = scale;
return BitmapFactory.decodeStream(new FileInputStream(f), null, o2);
} catch (FileNotFoundException e) {
// TODO: Do something
}
return null;
}

// Use Option class instead of BitmapFactory.Options
Options opts = new Options();
opts.inJustDecodeBounds = true;
BitmapFactory.decodeFile(path, opts);
Log.e("optwidth",opts.outWidth+"");
opts.inJustDecodeBounds = false;
if(opts.outWidth>500){
opts.inSampleSize = 4;
mBitmap = BitmapFactory.decodeFile(path, opts);
}
else mBitmap = BitmapFactory.decodeFile(path, opts);
Note: It can degrades the quality of Image but surely it can remove your Out of memory error for bitmap according to my knowledge. for more details check this link: Handling large Bitmaps

Develop Reference

The Android operating system is a mobile operating system that was developed by Google (GOOGL?) to be primarily used for touchscreen devices, cell phones, and tablets.

Show a ProgressBar while saving/showing a SQLite database - android

use this ProgressDialog pDialog = new ProgressDialog(this); pDialog.setMessage("please wait..."); pDialog.setProgressStyle(ProgressDialog.STYLE_SPINNER); pDialog.setCancelable(false); pDialog.show(); and after data load dismiss the progress dialog pDialog.dismiss();

When your function showRecords() is calling in the next line set progress bar visible and when the function is fully executed make progress bar gone. I guess u know how to add progress bar because u didn't mention how to use it so.
