Introduction screen similar to Flickr

Creating Introduction screen like Flickr or other Yahoo apps ..



Prerequisite for this  we should have the basic understand the working on Fragments and Activity working ..
Also we should have worked with animation class ..

Here we are trying to get the basic idea / getting the basic working model .


So here we go ..

Show Dialog using Service

Hi ,

In this post lets try to display a dialog box by using a service .
It's a common problem we face while and most of the time we end up by getting Windows Bad Token exception ... as we cannot use service object to display a dialog , So what's the turn around ..


Hears the solution ..

Create an Activity and display a dialog using it , but while defining an activity in Manifest file just set the theme as dialog box .


Chalo lets C how actually its done ..



Hear's my main activity , I am using it to start the service ..

package com.android.servicedialog;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity  implements OnClickListener{

Button btnStart;
Button btnStop;
private Intent intent;

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


btnStart = (Button) findViewById(R.id.btnStartService);
btnStop = (Button) findViewById(R.id.btnStopService);

btnStart.setOnClickListener(this);
btnStop.setOnClickListener(this);
intent = new Intent(MainActivity.this , DemoService.class);


}

@Override
public void onClick(View v) {

if (v.getId() == R.id.btnStartService) {

MainActivity.this.startService(intent);


}else if(v .getId() == R.id.btnStopService){

MainActivity.this.stopService(intent);

}
}


}





Here come's the service code ...
A simple service which starts a activity on its onStart method



package com.android.servicedialog;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;

public class DemoService extends Service {

@Override
public IBinder onBind(Intent intent) {

return null;
}


@Override
public int onStartCommand(Intent intent, int flags, int startId) {

intent = new Intent(DemoService.this , DialogActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
this.startActivity(intent);
return super.onStartCommand(intent, flags, startId);
}

@Override
public void onDestroy() {
super.onDestroy();
}



}

This is the Activity code .. from here we are going to show the Dialog box . 

package com.android.servicedialog;

import android.app.Activity;

import android.os.Bundle;

import android.view.Window;

public class DialogActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

requestWindowFeature(Window.FEATURE_NO_TITLE);

Utils.showAlertDialogBox("Sample Msg from Service", DialogActivity.this);

}

}

This is the Util's class .. here we have created a Custom Dialog Box 

package com.android.servicedialog;

import android.app.Activity;

import android.app.Dialog;

import android.content.Context;

import android.view.View;

import android.view.Window;

import android.view.View.OnClickListener;

import android.view.WindowManager;

import android.widget.Button;

import android.widget.TextView;

public class Utils {

/*

 * Display alert dialog box as per the parameter

 */

public static void showAlertDialogBox(String msg, final Activity activity) {

final Dialog dialog = new Dialog(activity);

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

dialog.setContentView(R.layout.custom_dialog);

TextView title = (TextView) dialog.findViewById(R.id.textTitle);

title.setText("BreakDown!!");

TextView txtSubTitle = (TextView) dialog

.findViewById(R.id.textSubTitle);

txtSubTitle.setText(msg);

Button dialogButton = (Button) dialog.findViewById(R.id.btnOk);

// if button is clicked, close the custom dialog

dialogButton.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

dialog.dismiss();

activity.finish();

}

});

dialog.show();

}

}

Here comes the MOST IMP part .. The manifest file .. Here we have defined the activity and then set the style to Dialog ..

      < service
            android:name="com.android.servicedialog.DemoService">
       
        < /service>
   
       < activity
            android:name="com.android.servicedialog.DialogActivity"
            android:theme="@style/Theme.AppCompat.CompactMenu.Dialog">
       
      < /activity>

   

Android Butterknife

Android Butterknife

I came across butterknife few weeks back when I was going through the resumes and I started reading about dependency injections in android. Butterknife injects code at compile time and almost similar to the java annotations .
I have found it very useful and easy to use in android but very few of us know about it .  So lets try and use it and try to understand if it is helpful or not .

WHY SHOULD WE USE IT ??
It reduces code and make developer life easy . Also help in maintain code readability. 

Prerequisites 

Download the jar 
Click here to download jar

If link dose not work do drop mail or comment so that I can share  the latest version 4.0.1

Create a Android project and the lib as the usual process 

Add annotaions 

Add Factory Path Jar 

Once we are done till here we are full set to use butter knief
Now here comes the main QUESTION 



Lets take a look at normal way we code in Android till now .


Declaring variables

ImageView mTeamOne;
ImageView mTeamTwo;
Button mButton;

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

View view = inflater.inflate(R.layout.fragment_current_matched, container, false);
mTeamOne = (ImageView) view.findViewById(R.id.imageview_teamone);
mTeamTwo = (ImageView) view.findViewById(R.id.imageview_teamtwo);
mButton = (ImageView)  view.findViewById( R.id.imageview_button);


}


But there's a smart way butter knife provides 

public class MainActivity extends Activity {

@InjectView(R.id.button1) Button button_one;
@InjectView(R.id.button2) Button button_two;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);
ButterKnife.inject(this);

}
}


Setting onClickListeners

Normal way to do it.

button_one.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

}
});


button_two.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

}
});


ButterKnief Smater way

@OnClick(R.id.button1)
public void attemptLogin() {
         // Logic
}

Now lets see how we can set listeners for multiple views 

@OnClick({R.id.button1 , R.id.button2})
public void doOnClick(View v){

switch (v.getId()) {
case R.id.button1:
showToast(v, "One");
break;

case R.id.button2:
showToast(v, "Two");
break;
default:
break;
}

}


Performance 

RoboGuice and Dagger does the same thing but make a performance impact as it's done on runtime using reflection and in ButterKnief its done at compiletime .

Thanks for reading and hope it helped U..

Android Air Gesture Example

Hi ...

Today I learned something about Air gestures and was thinking of sharing it.

Air Gestures is included in android since API level 14 which is Android 4.0... In market we have devices like Samsung S4 and many more about to launch .....

So lets try to understand the Air Gestures and try to implement it.

We need to overwrite the "setOnHoverListener" method of view where we need hover gestures .

Here is an example where I have tried to implement  onHover change on a listview

listView.setOnHoverListener( new OnHoverListener() {



@Override
public boolean onHover(View v, MotionEvent event) {
try {

switch (event.getAction()) {

// THIS IS POINT WHERE HAND WAS DETECTED
                case MotionEvent.ACTION_HOVER_ENTER:                    
               
                      x_enter = event.getX();
                    y_enter = event.getY();
                 
                    break;
// THESE ARE THE POINTS WHICH U WILL GET WHEN THE MOVEMENT IS GOING ON
                case MotionEvent.ACTION_HOVER_MOVE:                    
                 
                      event.getX();
                     event.getY();
                 
                    break;
// THESE ARE THE END POINTS WHERE THE HAND MOVEMENT FINISHED
                case MotionEvent.ACTION_HOVER_EXIT:
                 
                    x_exit = event.getX();
                    y_exit = event.getY();
                   
//ALGORITHM TO CALCULATE LEFT OR RIGHT MOVEMENT
                    decideMovement(x_enter, y_enter, x_exit, y_exit);
                    break;
            }

} catch (Exception e) {
// TODO: handle exception
}

return true;
}
});

public void decideMovement(float x_enter,float y_enter,float x_exit,float y_exit ){

// NOW WE CAN DO THE GESTURE DETECTION CALCULATIONS TO FIND OUT ANY MOVEMENTS WE WANT EG TOP,BOTTOM,RIGHT,LEFT

    float diffY = y_exit - y_enter;
    float diffX = x_exit - x_enter;
     
       if (diffX > 0) {
           slideLeft();
       } else {
           slideRight();
       }
     
   
}

Android ListView with Radio Buttons and Selected items

Hi Guys ,

Lets try to create a List View in Android which has a Radio button so we can choose from the options .

To create a list view we have to define it in xml file . But if we want to make the list view with radio buttons then we have set choice mode property .

for eg :

<ListView

        android:id="@+id/lstDemo"

        android:layout_width="fill_parent" 

        android:layout_height="wrap_content"

        android:choiceMode="singleChoice">

     

    </ListView>

Then once our xml is ready we can create the List view object in Activity .

ListView listView;

ArrayList< String>arrayList; // list of the strings that should appear in ListView

ArrayAdapter arrayAdapter; // a middle man to bind ListView and array list 

In addition to list view we need objects of ArrayList and ArrayAdapter .

now we have to initialize all objects in Oncreate() method .

 listView = (ListView) findViewById(R.id.lstDemo);

// LIST OF STRINGS / DATA THAT SHOULD APPEAR IN LISTVIEW HERE WE HAVE HARD CODED IT WE CAN TAKE THIS INPUT FROM USER AS WELL

arrayList = new ArrayList();

        arrayList.add("India");

        arrayList.add("USA");

        arrayList.add("England");

        arrayList.add("Singapur");

        arrayList.add("China");

        arrayList.add("Canada");

        arrayList.add("Srilanka");

        arrayList.add("SouthAfrica");

        

 arrayAdapter = new ArrayAdapter(getApplicationContext(),android.R.layout.simple_list_item_single_choice,arrayList);

 listView.setAdapter(arrayAdapter);

Thats it if we run the application we will be able to see a list view with radio buttons. 

Now that we have list view with radio buttons lets try to highlight the selected items.

For doing this we should get the selected items in list view , for this we have to implement 

onitemClick listener in listview so here goes the code.

   listView.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView arg0, View view, int position,

long arg3) {

}

});

      When we click on item on list view we can get it catch item selected in itemClickedListener.

So view is the item clicked in list view and position is the position of that item in list view which is clicked.

      Now that we know which item is click we can easily change the color of text but when we click on next item we we have to deselect the old selected item means recolor it back to default , and then hight the new selected item by coloring it .

      Lets C how to do it .

 listView.setOnItemClickListener(new OnItemClickListener() {

@Override

public void onItemClick(AdapterView arg0, View view, int position,

long itemId) {

/*  

*  when we click on item on list view we can get it catch item here.

* so view is the item clicked in list view and position is the position 

* of that item in list view which was clicked.

* 

* Now that we know which item is click we can easily change the color

* of text but when we click on next item we we have to deselect the old 

* selected item means recolor it back to default , and then hight the 

* new selected item by coloring it .

* 

* So here's the code of doing it.

* 

* 

* */

CheckedTextView textView = (CheckedTextView) view;

for (int i = 0; i < listView.getCount(); i++) {

textView= (CheckedTextView) listView.getChildAt(i);

if (textView != null) {

textView.setTextColor(Color.WHITE);

}

}

listView.invalidate();

textView = (CheckedTextView) view;

if (textView != null) {

textView.setTextColor(Color.BLUE);

}

}

});

You can take a look of code here 

XML code

xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="fill_parent"

    android:layout_height="fill_parent"

    android:orientation="vertical" >

    <ListView

        android:id="@+id/lstDemo"

        android:layout_width="fill_parent" 

        android:layout_height="wrap_content"

        android:choiceMode="singleChoice">

        listView.setAdapter(arrayAdapter);

        

        

        //  LETS HIGHLIGHT SELECTED ITEMS

        

        listView.setOnItemClickListener(new OnItemClickListener() {

@Override
