Disable future dates from DatePickerDialog in Android

As we already know DatePickerDialog will be used to allow user to select date. It is useful when user wants to select Date of Birth or Start Date or End Date etc.

Here is the small code snippet of creating DatePickerDialog.

Calendar calendar = Calendar.getInstance();
int mYear = calendar.get(Calendar.YEAR);
int mMonth = calendar.get(Calendar.MONTH);
int mDay = calendar.get(Calendar.DAY_OF_MONTH);

DatePickerDialog dpDialog = new DatePickerDialog(this, myDateListener, mYear, mMonth, mDay);
dpDialog.show();

Calendar calendar = Calendar.getInstance();

int mYear = calendar.get(Calendar.YEAR);

int mMonth = calendar.get(Calendar.MONTH);

int mDay = calendar.get(Calendar.DAY_OF_MONTH);

DatePickerDialog dpDialog = new DatePickerDialog(this, myDateListener, mYear, mMonth, mDay);

dpDialog.show();

ArrayAdapter in AlertDialog

We can always use ListView or RecyclerView for selection from list of items, but if we have small amount of choices and among those choices we want user to select one, we can use AlertDialog.Builder setAdapter.

private void showDialog()
{
    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Choose any item");

    final List<String> lables = new ArrayList<>();
    lables.add("Android Gig");
    lables.add("EventBus Library In Android");
    lables.add("Android’s Runtime Permission");
    lables.add("Part of TextView clickable");

    ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
            android.R.layout.simple_dropdown_item_1line, lables);
    builder.setAdapter(dataAdapter, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(MainActivity.this,"You have selected " + lables.get(which),Toast.LENGTH_LONG).show();
        }
    });
    AlertDialog dialog = builder.create();
    dialog.show();
}

private void showDialog()

{

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setTitle("Choose any item");

final List<String> lables = new ArrayList<>();

lables.add("Android Gig");

lables.add("EventBus Library In Android");

lables.add("Android’s Runtime Permission");

lables.add("Part of TextView clickable");

ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,

android.R.layout.simple_dropdown_item_1line, lables);

builder.setAdapter(dataAdapter, new DialogInterface.OnClickListener() {

@Override

public void onClick(DialogInterface dialog, int which) {

Toast.makeText(MainActivity.this,"You have selected " + lables.get(which),Toast.LENGTH_LONG).show();

}

});

AlertDialog dialog = builder.create();

dialog.show();

}
