I hope this tutorial might be helpful to all android developer to search or filter the item of the custom list view. Here the list view which shows in Alert-dialog. And we can search the item of the list view.
Here I am creating the ListView and Editext programatically and search the item of the list view. So lets start the coding to search the item of the listview in alert dialog.
txt_item=(EditText)findViewById(R.id.editText_item); btn_listviewdialog=(Button)findViewById(R.id.button_listviewdialog); btn_listviewdialog.setOnClickListener(this); } @Override public void onClick(View arg0) {
AlertDialog.Builder myDialog = new AlertDialog.Builder(MainActivity.this);
final EditText editText = new EditText(MainActivity.this); final ListView listview=new ListView(MainActivity.this); editText.setCompoundDrawablesWithIntrinsicBounds(R.drawable.discoverseed_larg1, 0, 0, 0); array_sort=new ArrayList (Arrays.asList(TitleName)); LinearLayout layout = new LinearLayout(MainActivity.this); layout.setOrientation(LinearLayout.VERTICAL); layout.addView(editText); layout.addView(listview); myDialog.setView(layout); CustomAlertAdapter arrayAdapter=new CustomAlertAdapter(MainActivity.this, array_sort); listview.setAdapter(arrayAdapter); listview.setOnItemClickListener(this); editText.addTextChangedListener(new TextWatcher() { public void afterTextChanged(Editable s){
} public void beforeTextChanged(CharSequence s, int start, int count, int after){
} public void onTextChanged(CharSequence s, int start, int before, int count) { editText.setCompoundDrawablesWithIntrinsicBounds(0, 0, 0, 0); textlength = editText.getText().length(); array_sort.clear(); for (int i = 0; i < TitleName.length; i++) { if (textlength <= TitleName[i].length()) {
Android it�s very easy to set the time using the android.widget.TimePicker component. In this tutorial we are going to see how the user can select the hour, and the minute using the android.app.TimePickerDialog which is an easy to use the dialog box.
In this tutorial I am creating the custom Time Picker with minute interval 00-15-30-45.
So lets start the coding to create the custom time picker in android.
This tutorial might be helpful to all developer to upload the image or any file on the server. Most of the critical code that most of the beginner facing stuff to upload image on server.
For this using multipart boundary. So here question is arises what is multipart boundary and why use it? The Content-Type field for multipart entities requires one parameter, "boundary", which is used to specify the encapsulation boundary. The encapsulation boundary is defined as a line consisting entirely of two hyphen characters ("-", decimal code 45) followed by the boundary parameter value from the Content-Type header field. Thus, a typical multipart Content-Type header field might look like this:
This indicates that the entity consists of several parts, each itself with a structure that is syntactically identical to an RFC 822 message, except that the header area might be completely empty, and that the parts are each preceded by the line --gc0p4Jq0M2Yt08jU534c0p.
Things to Note:
The encapsulation boundary must occur at the beginning of a line, i.e., following a CRLF (Carriage Return-Line Feed)
The boundary must be followed immediately either by another CRLF and the header fields for the next part, or by two CRLFs, in which case there are no header fields for the next part (and it is therefore assumed to be of Content-Type text/plain).
Encapsulation boundaries must not appear within the encapsulations, and must be no longer than 70 characters, not counting the two leading hyphens.
The encapsulation boundary following the last body part is a distinguished delimiter that indicates that no further body parts will follow. Such a delimiter is identical to the previous delimiters, with the addition of two more hyphens at the end of the line. More Details Here.
Here first I am using the code for getting the image from the gallery and set on image-view. And the set image path of the gallery on textview and send to this path for upload the image. Lets start the code:
Please put the UploadToServer.php file inside the www folder of the WAMP Server. And create the folder uploads inside the www folder of the wamp. See the screen shot to upload the pictures.
You can download the source code file with php file UploadFileOnServer. Cheers Guys!
Today we have share the knowledge about the lazy loading image download from the internet in android. The images will downloaded very fast with the help of the multiple thread.
Images that are not visible on the initial page load are not loaded or downloaded until they come into the main viewing area. Once an image comes into view it is then downloaded and faded into visibility. Scroll down this page to see the action for same.
For this i am using the open source library universal image loader made by nostra. Here you can download the universal image loader library Here.
I added the video to show the lazy loading the image and show in the list view.
In this tutorial I describe about the slide menu navigation drawer in android. For this I have to use the Sherlock library as for supporting the Sherlock Fragment which is supported the lower version of API also.
ActionBarSherlock is an extension of the support library designed to facilitate the use of the action bar design pattern across all versions of Android with a single API.
The library will automatically use the native action bar when appropriate or will automatically wrap a custom implementation around your layouts. This allows you to easily develop an application with an action bar for every version of Android from 2.x and up.You can download the Sherlock library from Here.
Now you just import this library into your project area of eclipse. And Add this action sherlock library with your uses of project. How to Add the library with your project? Right Click of your proejct -> Properties -> Android -> Add (click here and select your library).
In this library android support v4 library already there then there is no need to put android-support v4 library in your project. If this is availability in your project libs then remove from there. Navigation Drawer: The navigation drawer is a panel that transitions in from the left edge of the screen and displays the app�s main navigation options. The user can bring the navigation drawer onto the screen by swiping from the left edge of the screen or by touching the application icon on the action bar. You can download the sample for same by use of Action Bar and more detail about Navigaion DrawertHere.
So in this tutorial I have implemented this navigation drawer features by using of sherlock library. Here is the video you can watch what have implemented with this.
Now Lets Start the Coding to implements the Slid Menu Navigation Drawer in android.
textdescription.setText("I'm currently working as Android developer, interested in a wide-range of technology topics, including programming languages, opensource and any other cool technology that catches my eye. I love developing apps for Android, designing and coding."); return view; }
@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
} }
Manifest.xml
Same way you can add the Fragment2, Fragment3 and Fragment4. I have not added this classes to make clean this article.
Today we are learning about the exporting and importing the table data from DB to CSV and CSV to DB table. In that tutorial first we are doing to insert the Person data into DB table by using the ORM open source. Then Exporting the same table data into the CSV file and stored in sd card.
For inserting the text data into sqlite table by using the ORM open source. More detail about the ORM open source in the last tutorial Here.
For exporting the db table we are using the opencsv.jar file. With the help of this jar file we are able to write and read the data of table and write into the CSV file. You can download the opencsv.jare file Here
In the next part we are sending to mail the csv file with attached with the help of android.content.Intent.ACTION_SEND. So lets start the coding for the same.
if (personRuntimeDao == null) { personRuntimeDao = getRuntimeExceptionDao(Person.class); } return personRuntimeDao; } public int addPersonData(Person project) { Log.v(TAG, "addPersonData call"); RuntimeExceptionDao dao = getPersonDataDao(); int i = dao.create(project); return i; }
public List GetDataPerson() { Log.v(TAG, "GetDataPerson call"); RuntimeExceptionDao simpleDao = getPersonDataDao(); List list = simpleDao.queryForAll(); return list; }
public void deleteAllPerson() { Log.v(TAG, "deleteAllPerson call"); RuntimeExceptionDao dao = getPersonDataDao(); List list = dao.queryForAll(); dao.delete(list); }
File dbFile=getDatabasePath("person.db"); Log.v(TAG, "Db path is: "+dbFile); //get the path of db
File exportDir = new File(Environment.getExternalStorageDirectory(), ""); if (!exportDir.exists()) { exportDir.mkdirs(); }
file = new File(exportDir, "PersonCSV.csv"); try {
file.createNewFile(); CSVWriter csvWrite = new CSVWriter(new FileWriter(file));
//ormlite core method List listdata=dbhelper.GetDataPerson(); Person person=null;
// this is the Column of the table and same for Header of CSV file String arrStr1[] ={"First Name", "Last Name", "Address", "Email"}; csvWrite.writeNext(arrStr1);
Today I am sharing the code to get the call logs of a android device. For Access the call logs we need to first the aware about Content Provider.
Content providers manage access to a structured set of data. They encapsulate the data, and provide mechanisms for defining data security. Content providers are the standard interface that connects data in one process with code running in another process. More About the Content Provider you can visit the android developer siteHere.
One of the most commonly used Content Providers isCallLog.Callswhich is used to provide access to call logs data. Call logs contain information about outgoing, incoming and missed calls. Letsstart the coding for call logs data accessing from the device.
int number = managedCursor.getColumnIndex( CallLog.Calls.NUMBER ); int type = managedCursor.getColumnIndex( CallLog.Calls.TYPE ); int date = managedCursor.getColumnIndex( CallLog.Calls.DATE); int duration = managedCursor.getColumnIndex( CallLog.Calls.DURATION);
