The wheel widget for Android:

Introduction:

• You can use wheel widget for country,state,date,time selection.you can use this wheel control in your project. You have to include WheelLibrary as a library for run this project.

Usage:

• In this project there are six main class.

1) CitiesActivity : * This class is use for city selection on the base of selected country. We use one wheelview for country and set CountryAdapter in this view.

final WheelView country = (WheelView) findViewById(R.id.country);
country.setVisibleItems(3);
country.setViewAdapter(new CountryAdapter(this));

• Here we use another wheelview for city.When we change and scroll country wheel than updateCities(city, cities, newValue) function will be called in which cities will be list out on the base of selected country.

country.addChangingListener(new OnWheelChangedListener() {
public void onChanged(WheelView wheel, int oldValue, int newValue) {
if (!scrolling) {
updateCities(city, cities, newValue);
}
}
});

country.addScrollingListener( new OnWheelScrollListener() {
public void onScrollingStarted(WheelView wheel) {
scrolling = true;
}
public void onScrollingFinished(WheelView wheel) {
scrolling = false;
updateCities(city, cities, country.getCurrentItem());
}
});

Updates the city wheel

private void updateCities(WheelView city, String cities[][], int index) {
ArrayWheelAdapter<String> adapter =
new ArrayWheelAdapter<String>(this, cities[index]);
adapter.setTextSize(18);
city.setViewAdapter(adapter);
city.setCurrentItem(cities[index].length / 2);
}

2) DateActivity :

• In this activity we use three wheelview for day,year and month.

final WheelView month = (WheelView) findViewById(R.id.month);
final WheelView year = (WheelView) findViewById(R.id.year);
final WheelView day = (WheelView) findViewById(R.id.day);

• we use DateArrayAdapter for month and DateNumericAdapter for year and day.When we change and scroll wheelview than OnWheelChangedListener() will be called in which we specify updateDays(year, month, day) .this function set max days according to selected month and year.

void updateDays(WheelView year, WheelView month, WheelView day) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, calendar.get(Calendar.YEAR) + year.getCurrentItem());
calendar.set(Calendar.MONTH, month.getCurrentItem());
int maxDays = calendar.getActualMaximum(Calendar.DAY_OF_MONTH);
day.setViewAdapter(new DateNumericAdapter(this, 1, maxDays, calendar.get(Calendar.DAY_OF_MONTH) - 1));
int curDay = Math.min(maxDays, day.getCurrentItem() + 1);
day.setCurrentItem(curDay - 1, true);
}

3) PasswActivity:

• When we change and scroll wheelview than OnWheelChangedListener() will be called in which we specify updateStatus().this function check whichever number selected is true or not.

private void updateStatus() {
TextView text = (TextView) findViewById(R.id.pwd_status);
if (testPin(2, 4, 6, 1)) {
text.setText("Congratulation!");
} else {
text.setText("Invalid PIN");
}
} private boolean testPin(int v1, int v2, int v3, int v4) {
return testWheelValue(R.id.passw_1, v1) && testWheelValue(R.id.passw_2, v2) &&
testWheelValue(R.id.passw_3, v3) && testWheelValue(R.id.passw_4, v4);
}

4) SlotMachineActivity:

• This activity do same functionality like PasswActivity done.

5) Time2Activity:

• This activity do same functionality like DateActivity done.Additional code is for time selection.

6) TimeActivity:

• This activity do same functionality like Time2Activity but here we just select time.we can not select date.

Swipe To Dismiss ListView For Android:

Introduction:

Here I am sharing a code to perform delete operation on listview  by just swiping it to right or left.

 

• Keep in mind this thing will only work in 4.0 or above. First Download the Demo from here.
• After extracting the zip you will find three class file in src project.

1) Main Activity

• The Class which displays the view to user and also has listener implementation on button and listview.

2) SwipeDismissTouchListener

• This class is responsible to listen swipe over the button’s object.

dismissableButton.setOnTouchListener(new SwipeDismissTouchListener(
 dismissableButton,
 null,
 new SwipeDismissTouchListener.OnDismissCallback() {
 @Override
 public void onDismiss(View view, Object token) {
 dismissableContainer.removeView(dismissableButton);
 }
 }));

3) SwipeDismissListViewTouchListener

• This class is responsible to listen swipe over the listview’s item object. In below code snippet just check that we are passing listview object while constructing an object of this class.

SwipeDismissListViewTouchListener touchListener =
new SwipeDismissListViewTouchListener(
listView,
new SwipeDismissListViewTouchListener.OnDismissCallback() {
@Override
public void onDismiss(ListView listView, int[] reverseSortedPositions) {
for (int position : reverseSortedPositions) {
myAdapter.remove(myAdapter.getItem(position));
}
myAdapter.notifyDataSetChanged();
}
});

• Both SwipeDismissTouchListener and SwipeDismissListViewTouchListener implements OnTouchListener which listens every touch on particular views.
• You can also download source code from here.

Pin Progress For Android:

Introduction:

• Custom indicator that could show all of the information in a tiny footprint.

• The color indicates whether it's downloaded (blue) or not (gray). The appearance of the pin indicates whether the download is permanent (white, upright) or temporary (gray, diagonal). And when state is in the process of changing, progress is indicated by a moving pie chart.
• We can use this pie chart to show our progress instead of progress bar, it takes minimum space to show & flexibility to appear on top of the downloading content.

ColorMixer For Android:

Introduction:

Sometimes, you want your users to pick a color. A simple approach is to give the user a fixed roster of a handful of colors -- easy, but limited. A fancy approach is to use some form of color wheel, but these can be difficult to use on a touchscreen and perhaps impossible without a touchscreen.

ColorMixer is a widget that provides a simple set of SeekBars to let the user mix red, green, and blue to pick an arbitrary color. It is not very big, so it is easy to fit on a form, and it is still fairly finger-friendly.

It is also packaged as a dialog (ColorMixerDialog), a dialog-themed activity (ColorMixerActivity), and a preference (ColorPreference).

Usage:

• ColorMixer:

ColorMixer is a simple widget. Given that you have the parcel installed in your project, or have manually merged the source and resources into your project, you can add the widget to a layout like any other:

<com.commonsware.cwac.colormixer.ColorMixer
android:id="@+id/mixer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>

You can call getColor() and setColor() to manipulate the color at runtime. You can also call setOnColorChangedListener() to register a ColorMixer.OnColorChangedListener object, which will be called with onColorChanged() when the color is altered by the user.

• ColorMixerDialog:

ColorMixerDialog is an AlertDialog subclass. Hence, to create and show the dialog, all you need to do is create an instance and show() it:

new ColorMixerDialog(this, someColor, onDialogSet).show();

In the above code snippet, this is a Context (e.g., an Activity), someColor is the color you want to start with, and onDialogSet is a ColorMixer.OnColorChangedListener that will be notified if the user clicks the "Set" button on the dialog and has changed the color from the initial value.

• ColorMixerActivity:

ColorMixerActivity is a dialog-themed Activity. This is useful for situations where you want a dialog but do not want to deal with a dialog.

To use it, add it as an activity to your project. You will need to use the full package in your <activity> element, marking it as using Theme.Dialog. Here is one implementation, from the demo/ project:

<activity android:name="com.commonsware.cwac.colormixer.ColorMixerActivity"
android:label="@string/app_name"
android:theme="@android:style/Theme.Dialog">
</activity>

In the Intent you use to start the activity, you can supply the starting color via a ColorMixerActivity.COLOR integer extra, and the dialog title via a ColorMixerActivity.TITLE string extra. For example:

Intent i=new Intent(this, ColorMixerActivity.class);
i.putExtra(ColorMixerActivity.TITLE, "Pick a Color");
i.putExtra(ColorMixerActivity.COLOR, mixer.getColor());
startActivityForResult(i, COLOR_REQUEST);

• ColorPreference:

ColorPreference is a Preference class, to be referenced in preference XML and loaded into a PreferenceActivity. It has no attributes beyond the standard ones.

<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android">
<com.commonsware.cwac.colormixer.ColorPreference
android:key="favoriteColor"
android:defaultValue="0xFFA4C639"
android:title="Your Favorite Color"
</PreferenceScreen>

The preference is stored as an integer under the key you specify in the XML.

• Dependencies:

This depends upon the cwac-parcel library for accessing project-level resources Which is already included in ColorMixer Library. Include ColorMixerLibrary.

Audalyzer For Android:

Introduction :

It displays sound readings from the microphone as a waveform display, as a frequency spectrum, and as a dB meter. dB levels are relative to the maximum input level of your device.

Since microphone sensitivity varies between individual devices, let alone models, it's impossible to generate accurate sound level readings with this app; so all data should be taken with a pinch of salt. Still, it may be interesting when used to compare sound readings at different locations.

Decibel (dB) scales are logarithmic, which means that each unit on the scale is a multiple of the underlying unit. So, 0dB represents some "base" level; 10dB is 10 times this level; 20dB is 100 times; etc. If the base level is a zero input signal, then 10dB is 10 times this, which is also zero; 20dB would be 100 times zero, also zero; etc. In other words, an actual zero input can't be represented. So the base level has to be some other value. There is no minimum input signal; but there is a maximum, where the input is fully saturated. So we choose this as the base -- 0dB -- and other values are derived from this. Hence -10dB means 1/10th of the maximum, -20dB is 1/100th, etc.

You need to include two libraries for run this project : 1) HermitAndroid 2) HermitLibrary

Features :
Displays waveform, frequency spectrum, and dB meter.
Meter shows instantaneous, average, and peak values.
