Cutom Actionbar in android

Here i am going to show you how to create custom action bar in all the screen.

My XML:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

Shared Preference in android

Application shared preferences allows you to save and retrieve key, value pair data. Before getting into tutorial, I am giving basic information needed to work with shared preferences.

Initialization
Application shared preferences can be fetched using getSharedPreferences() method.You also need an editor to edit and save the changes in shared preferences. The following code can be used to get application shared preferences.

SharedPreferences pref = getApplicationContext().getSharedPreferences("MyPref", 0); // 0 - for private mode
Editor editor = pref.edit();

Storing Data

You can save data into shared preferences using editor. All the primitive data types like booleans, floats, ints, longs, and strings are supported. Call editor.commit() in order to save changes to shared preferences.

editor.putBoolean("key_name", true); // Storing boolean - true/false
editor.putString("key_name", "string value"); // Storing string
editor.putInt("key_name", "int value"); // Storing integer
editor.putFloat("key_name", "float value"); // Storing float
editor.putLong("key_name", "long value"); // Storing long

editor.commit(); // commit changes

Retrieving Data

Data can be retrived from saved preferences by calling getString() (For string) method. Remember this method should be called on Shared Preferences not on Editor.

//returns stored preference value
//If value is not present return second param value - In this case null
pref.getString("key_name", null); // getting String
pref.getInt("key_name", null); // getting Integer
pref.getFloat("key_name", null); // getting Float
pref.getLong("key_name", null); // getting Long
pref.getBoolean("key_name", null); // getting boolean

Clearing / Deleting Data

If you want to delete from shared preferences you can call remove(“key_name”) to delete that particular value. If you want to delete all the data, call clear()

editor.remove("name"); // will delete key name
editor.remove("email"); // will delete key email

editor.commit(); // commit changes

Following will clear all the data from shared preferences

editor.clear();

editor.commit(); // commit changes

Code for SharedPreference


public class SessionManager {

// http://www.androidhive.info/2012/08/android-session-management-using-shared-preferences/

SharedPreferences pref;
Editor editor;
Context context;
int PRIVATE_MODE = 0;
String prefName = "eatPref";
String key_NAME = "username";
String key_PASS = "password";
String IS_LOGIN = "IsLoggedIn";

   //constructor
public SessionManager(Context context) {
this.context = context;
pref = context.getSharedPreferences(prefName, PRIVATE_MODE);
editor = pref.edit();
}

public void login(String username, String password) {
editor.putBoolean(IS_LOGIN, true);
editor.putString(key_NAME, username);
editor.putString(key_PASS, password);
editor.commit();
}

public HashMap<String, String> getDetails() {
HashMap<String, String> user = null;
user.put(key_NAME, pref.getString(key_NAME, null));
user.put(key_PASS, pref.getString(key_PASS, null));
return user;
}

// Get Login State
public boolean isLoggedIn() {
return pref.getBoolean(IS_LOGIN, false);
}

}

LoginActivity:

public class Login extends Activity {

LinearLayout Signin;

EditText username;

EditText password;

@SuppressLint("ResourceAsColor")

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

// requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);

setContentView(R.layout.login_main);

// getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,

// R.layout.header);

username = (EditText) findViewById(R.id.username);

password = (EditText) findViewById(R.id.password);

password.setTypeface(Typeface.DEFAULT);

Signin = (LinearLayout) findViewById(R.id.signin_ll);

Signin.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View arg0) {

// TODO Auto-generated method stub

SessionManager sm = new SessionManager(getApplicationContext());

sm.login(username.getText().toString().trim().toLowerCase(),

password.getText().toString().trim().toLowerCase());

}

}

});

}

Where are shared preferences stored?

Split the Json format.

Here i am going to show you how to split the json format.

toJson() – Convert Java object to JSON format
fromJson() – Convert JSON into Java object

sample format.

{"user_id":"1","email":"xxx@gmail.com","password":"12","name":"yyy","gender":"male"}

Step1:
  Create a class for this json example

Class Info
{
public String user_id;
public String email;
public String password;
public String name;
public String gender;
}

Step2:
Download the gson jar file and add it in your lib folder.to know more about gson and json.

Step3:
//fromJson is used to convert back to object and display it.

        String result = "Your json string"
Gson gson = new Gson();
Info getResponse = gson.fromJson(result, Info.class);
        String name = getResponse.name; //To get the value of name.
        Toast.makeText(getApplicationContext(),
getResponse.name, Toast.LENGTH_LONG)
.show();

Cosume PHP(POST METHOD) webservice in android.

Here i am passing json string parameter to php webservice. To consume php post method we will use HttpPost.

To create JSON String in android:

JSONObject json = new JSONObject();

json.put("name", "");
json.put("email", "");
json.put("password", "");

Log.i("json Object", json.toString());

Pass the parameter to post method:

        List<NameValuePair> params = new ArrayList<NameValuePair>();

        params.add(new BasicNameValuePair("userinfo", json.toString()));

Get the response InputStream like this:

HttpResponse response;
InputStream is = null;

   response = client.execute(post);
HttpEntity httpEntity = response.getEntity();
is = httpEntity.getContent();

Full Code:

HttpResponse response;
JSONObject json = new JSONObject();
String json1 = "";
JSONObject jObj = null;
InputStream is = null;

DefaultHttpClient client = new DefaultHttpClient();

try {
HttpPost post = new HttpPost(
"Your URL");
json.put("name", "");
json.put("email", "");
json.put("password", "");

Log.i("jason Object", json.toString());
post.setHeader("userinfo", json.toString());

List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("userinfo", json.toString()));

post.setEntity(new UrlEncodedFormEntity(params));
response = client.execute(post);
HttpEntity httpEntity = response.getEntity();
is = httpEntity.getContent();

try {
BufferedReader reader = new BufferedReader(
new InputStreamReader(is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "n");
}
is.close();
json1 = sb.toString();
Log.i("jason Object", sb.toString());

Log.e("JSON", json1);
} catch (Exception e) {
Log.e("Buffer Error", "Error converting result " + e.toString());
}
// try parse the string to a JSON object
try {
jObj = new JSONObject(json1);
} catch (JSONException e) {
Log.e("JSON Parser", "Error parsing data " + e.toString());
}

// return JSON String

Log.d("final Response", jObj.toString());
Log.d("status", jObj.getString("status")); //Declare your status or message or json string variable

} catch (Exception e) {
e.printStackTrace();
}

AsyncTask in android

AsyncTask enables proper and easy use of the UI thread. This class allows to perform background operations and publish results on the UI thread without having to manipulate threads and/or handlers.

An asynchronous task is defined by a computation that runs on a background thread and whose result is published on the UI thread. An asynchronous task is defined by 3 generic types, called Params, Progress and Result, and 4 steps, called onPreExecute, doInBackground, onProgressUpdate and onPostExecute.

Read this fully more about AsyncTask

Coding:

public class Login extends Activity {

 LinearLayout Signin;

 protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        setContentView(R.layout.login_main);


Signin = (LinearLayout) findViewById(R.id.signin_ll);

Signin.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View arg0) {
// TODO Auto-generated method stub

                  myasynctask MAT = new myasynctask();
   MAT.execute();

   }
});

}

 class myasynctask extends AsyncTask<String, Void, String> {

       @Override
protected String doInBackground(String... params) {
   // TODO Auto-generated method stub
           //Background process like downloading, webservices etc...
           Log.d("doInBackground", "backgroundprocess is ongoing");
          return value;
}

        @Override
public void onPostExecute(String result) {
   // TODO Auto-generated method stub
             Log.d("PostExecute", "after finished the backgroundprocess");

Cosume PHP(GET METHOD) webservice in android.

Here i am going to show you the exact code for cosume php webservice in android. But in this example i have passes emailid and password in the url to check whether the user is valid or not.
To consume php get method we will use HttpGet.

Get the response InputStream like this:

InputStream is = null;

HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
is = httpEntity.getContent();

Full Code:

  InputStream is = null;
JSONObject jObj = null;
String json = "";

       //Place your own url here
String URL = "http://domain.com/login.php?email="
+ username.getText().toString().trim().toLowerCase()
+ "&password="
+ password.getText().toString().trim().toLowerCase() + "";

   Log.d("username", username.getText().toString().trim()
   .toLowerCase());
   Log.d("password", password.getText().toString().trim()
   .toLowerCase());

   // Making HTTP request
   // (http://www.androidhive.info/2012/01/android-login-and-registration-with-php-mysql-and-sqlite/)

Fetching image from GALLERY

•   To fetching image from the gallery. We use Intent.ACTION_GET_CONTENT in Intent function.
•   Then, We have to set type to intent.setType("image/*").

            Function

•             Intent(Intent.ACTION_GET_CONTENT).
•             setType("image/*").
•    startActivityForResult.

       <Button

        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/username"
        android:layout_centerHorizontal="true"
        android:textStyle="bold"
        android:text="Click" />

    Button clickBtn;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.menu);

 clickBtn=(Button)findViewById(R.id.button1);

clickBtn.setOnClickListener(new OnClickListener() {

@Override

                  cursor.moveToFirst();

                  int columnIndex = cursor.getColumnIndex(filePathColumn[0]);

                 //file path of selected image
                  filePath = cursor.getString(columnIndex);

How to fetch the value from the text box in android

In your XML:

            <EditText
                android:id="@+id/username"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_centerHorizontal="true"
                android:hint="Fetch the Value"
        />
         
            <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/username"
        android:layout_centerHorizontal="true"
        android:textStyle="bold"
        android:text="Click" />

(@+id/username)This is the id of the text box. Read this fully to declare id in XML layout.


In your Activity:

//To declare your EditText
   EditText fetch;
   String fetchValue;
   Button clickBtn;

   @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.your_layout);
     
 //binding editbox id with your activity
         fetch=(EditText)findViewById(R.id.username);
//to get the value from the textbox
         fetchValue=fetch.getText().toString();

      clickBtn=(Button)findViewById(R.id.button1);

clickBtn.setOnClickListener(new OnClickListener() {
 
   @Override
   public void onClick(View v) {
// TODO Auto-generated method stub
 Toast.makeText(getApplicationContext(),fetchValue, Toast.LENGTH_LONG).show();
   }
});
