Android Date and Time Picker

Today I am going to explain Date and Time Picker in android.

In many applications you require to set date and time feature. Its very simple to implement in android.

Android provide default Date and Time picker widget. You just use it in xml and do the pre-define code for display it.

Sample Code:

1) For Date Picker:

File: MainActivity.java

 public void populateSetDate(int year, int month, int day)
 {
    mEdit = (EditText)findViewById(R.id.editText1);
    mEdit.setText(month+"/"+day+"/"+year);
 }

 public class SelectDateFragment extends DialogFragment implements  DatePickerDialog.OnDateSetListener
 {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState)
    {
final Calendar calendar = Calendar.getInstance();
int yy = calendar.get(Calendar.YEAR);
int mm = calendar.get(Calendar.MONTH);
int dd = calendar.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(), this, yy, mm, dd);
    }
   
    public void onDateSet(DatePicker view, int yy, int mm, int dd)
    {
    populateSetDate(yy, mm+1, dd);
    }
 }

Output:

2) For Time Picker:

File: MainActivity.java

@Override
protected Dialog onCreateDialog(int id)
{
switch (id)
{
         case TIME_DIALOG_ID:
// set time picker as current time
return new TimePickerDialog(this, timePickerListener, hour, minute,false);
}
return null;
}

private TimePickerDialog.OnTimeSetListener timePickerListener =  new TimePickerDialog.OnTimeSetListener()
{
public void onTimeSet(TimePicker view, int selectedHour, int selectedMinute)
{
hour = selectedHour;
minute = selectedMinute;

// set current time into textview
textViewTime.setText(new  StringBuilder().append(padding_str(hour))..append(":")                              .append(padding_str(minute)));

// set current time into timepicker
timePicker.setCurrentHour(hour);
timePicker.setCurrentMinute(minute);

}
};

private static String padding_str(int c)
{
if (c >= 10)
            return String.valueOf(c);
else
            return "0" + String.valueOf(c);
}

Gridview in Android

Gridview is ViewGroup that displays items in two-dimensional, scrollable grid. The grid items are automatically inserted to the layout using ListAdapter.

In a simple meaning you can display items with grid. So your all items looks like same in your layout.

Here I display multiple images in GridView. When you click on any image it will display as a large image into Imageview.

So you can learn two things using this post. First is use of gridview and second is display selected item in other activity. 

Sample Code:

File: grid_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/grid_view"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:numColumns="auto_fit"
    android:columnWidth="90dp"
    android:horizontalSpacing="10dp"
    android:verticalSpacing="10dp"
    android:gravity="center"
    android:stretchMode="columnWidth" >  


</GridView>

File: AndroidGridLayoutActivity.java

GridView gridView = (GridView) findViewById(R.id.grid_view);

// Instance of ImageAdapter Class
gridView.setAdapter(new ImageAdapter(this));

/**
 * On Click event for Single Gridview Item
 * */
gridView.setOnItemClickListener(new OnItemClickListener() 
{
       @Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id) 
{
// Sending image id to FullScreenActivity
Intent i = new Intent(getApplicationContext(), FullImageActivity.class);
// passing array index
i.putExtra("id", position);
startActivity(i);
}

});

Listview In Android

Hello Friends,

In Android there are many types of listview available. Here I presented all major types of listview example with this post.

Types of Listview I include in this examples are:

1) Simple Listview : 
--> In this type you can see simple list of items with auto scrolling.

2) Listview with single choice :
--> When you use single choice in listview then you can see the items with radio button. You can select only one option from list and do the further use in your app.

3) Listview with multiple choice : 
--> When you use multiple choice in listview then you can see the items with check box. You can select multiple items from the list and do the further use in your app.

4) Filterable Listview : 
--> In filterable listview you can filter items which are start on same letter then select any one of them with simple click.

5) Listview with Images and Text : 
--> Here you can display images and its relevant text into listview.

6) Dynamically add items into listview : 
--> If you don't want to use fix item into listview then you can add your own items dynamically into listview using this option.

7) Delete selected items from listview : 
--> If you want to remove some items from listview then its easy to do it with this option.

For more details see the screen shots and demo code.

Send An Email In Android

Here I am going to explain how to send email using android.

For email sending you must need an Internet permission in your application. You can send an email via Share Intent.

You can write permission like: <uses-permission android:name="android.permission.INTERNET"/>

For Example:

String to = "";

String subject = "My Message";

Intent email = new Intent(Intent.ACTION_SEND);

email.putExtra(Intent.EXTRA_EMAIL, new String[]{ to});

email.putExtra(Intent.EXTRA_SUBJECT, subject);

email.putExtra(Intent.EXTRA_TEXT, et_message.getText().toString().trim());

 

//need this to prompts email client only

email.setType("message/rfc822");

 

startActivity(Intent.createChooser(email, "Choose an Email Client :"));

Custom Dialog In Android

Hello friends, In last post we have seen how to create alert dialog. Alert dialog is a default functionality in Android.

If you want to create your own dialog then what to do...??????

Let's start to create Custom Dialog in Android.

In this example i applied screen's background and Button with background, its border. So you can learn to customize button also.

Same like you can create a design for header, footer and any components according to your project.

Step 1: You need to create your own design for dialog.

Here I provide you sample code.

File : activity_custom_alert_dialog.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:background="@drawable/mainbg">

    <Button
        android:id="@+id/btn_click"
        android:layout_width="250dp"
        android:layout_height="45dp"
        android:text="Click Me"
        android:layout_gravity="center"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:layout_marginTop="20dp"
        android:typeface="serif"
        android:textStyle="bold"
        android:background="@drawable/btnbg"/>

</LinearLayout>

Step 2: Do the java code into your activity file.

File : CustomAlertDialog.java

protected void showCustomDialog() {
cad_dialog = new Dialog(CustomAlertDialog.this,android.R.style.Theme_Translucent);
cad_dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);

cad_dialog.setCancelable(true);
cad_dialog.setContentView(R.layout.customdialog);

edt_feedback = (EditText) cad_dialog.findViewById(R.id.etfeedback);
btn_ok = (Button) cad_dialog.findViewById(R.id.btnok);
btn_cancel = (Button) cad_dialog.findViewById(R.id.btncancel);

cad_dialog.show();

btn_ok.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "You have clicked OK...!!!",                                                 Toast.LENGTH_LONG).show();
cad_dialog.dismiss(); // Here you can perform any action as per your requirement.
}
});

btn_cancel.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
// TODO Auto-generated method stub
cad_dialog.dismiss();
}
});

}
