##About Simbiose
##Contribute
Fell free to fork, modify and send a pull request.
##How to
Clone with recursive tag the sau repository and import the /android project named SAU to eclipse and add it a android library on your android application and now you're ready to use it. You also can see the documentation on /doc/index.html
##Get It
##Examples
###Log
SimbiLog.print("Hello World"); //Print a normal String
SimbiLog.print(param1, foo1, foo2); //You can print a lot of objects
SimbiLog.printException(new Exception("A mock exception")); //Print Exceptions
SimbiLog.log(this, param1, foo1, null, foo2); //You can log your methods
SimbiLog.here(); //Easy "here" print
###Json
Foo foo = (Foo) JsonUtils.fromJsonOrNull("{}", Foo.class); //You can load objects from json strings powered by GSON core
JsonUtils.toJson(foo); //You can make json Strings from objects easily
###Shared Preferences
PreferencesHelper myPrefs = new PreferencesHelper(getContext());
myPrefs.put("Any Key", "Any Value"); //You can easily save data on shared preferences
myPrefs.put("Any Key", new Foo()); //You can storage objects too
myPrefs.getString("Any Key", "Default"); //Read is easy too
myPrefs.getStringOrEmpty(keyString); //if you do not want a default values
myPrefs.getObjectOrNull(keyObject, Foo.class); //Read objects
###Key Key Map
KeyKeyMap keyKeyMap = new KeyKeyMap(); //Know the KeyKey Map
String key1 = "Key 1"; //You can use any key, a String
int key2 = 2; //any number
Foo key3 = new Foo(); //or Objects too
keyKeyMap.put(key1, key2); //Now you mapped key1 <-> key2
keyKeyMap.get(key1); //returns the key2
keyKeyMap.get(key2); //returns the key1
keyKeyMap.get(key3); //returns null because you not mapped the key3
keyKeyMap.put(key1, key3); //Now you mapped key1 <-> key3 and key1 <- key2
keyKeyMap.get(key1); //returns the key3
keyKeyMap.get(key3); //returns the key1
keyKeyMap.get(key2); //returns the key1 too
keyKeyMap.get(null); //returns null
keyKeyMap.put(null, key3); //Now you mapped null <-> key3, key1 -> key3 and key1 <- key2
keyKeyMap.get(null); //returns key3
keyKeyMap.get(key3); //returns null
###Simple Encryption and Decryption of Strings
Encryption encryption = new Encryption(); //The encryptor
String key = "Some Key"; //The secret key to encrypt
String data = "top secret string"; //The text to be encrypted
String encrypted = encryption.encrypt(key, data); //Create the encrypted String
SimbiLog.print(encrypted); //Just to you see
String decrypted = encryption.decrypt(key, encrypted); //Back to original String
SimbiLog.print(decrypted); //Just to you see again
###Range
import static simbio.se.sau.iterable.Range.range; //It is like the range of python
for (int i : range(3)) //passes through the numbers 0, 1 and 2
SimbiLog.print("range example a", i);
for (int i : range(-4)) //passes through the numbers 0, -1, -2 and -3
SimbiLog.print("range example b", i);
for (int i : range(4, 7)) //passes through the numbers 4, 5 and 6
SimbiLog.print("range example c", i);
for (int i : range(-5, -30, 10)) //passes through the numbers -5, -15 and -25
SimbiLog.print("range example d", i);
###Range Seek Bar ####See the sample running to a better understanding of what the Range Seek Bar is
//put on xml file
<simbio.se.sau.view.RangeSeekBar
android:id="@+id/range_seek_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/button_resize_my_width"
android:layout_marginTop="@dimen/activity_vertical_margin"/>
RangeSeekBar<Integer> rangeSeekBar = (RangeSeekBar<Integer>) findViewById(R.id.range_seek_bar); //load from xml
rangeSeekBar.init( //init the params
0, //min value
100, //max value
BitmapFactory.decodeResource(getResources(), R.drawable.scrubber_control_normal_holo), //image to be the control BitmapFactory.decodeResource(getResources(), R.drawable.scrubber_control_pressed_holo), //image to be the controll pressed
this); //set listener and ends
rangeSeekBar.setNormalizedMinValue(0.3f); //default min value
rangeSeekBar.setNormalizedMaxValue(0.7f); //default max value
rangeSeekBar.setNotifyWhileDragging(true); //call listener when drawing
rangeSeekBar.setLineColor(Color.rgb(0, 153, 0)); //line color
####it will show something like that:
###Clipboard Text View ####A TextView that when is clicked copy your text to clipboard
//put on xml file
<simbio.se.sau.view.ClipboardTextView
android:id="@+id/clipboard_text_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/button_open_sql_example_activity"
android:layout_marginTop="@dimen/activity_vertical_margin"
android:text="@string/copy_me"
android:textAppearance="?android:attr/textAppearanceLarge" />
ClipboardTextView myCTV = (ClipboardTextView) findViewById(R.id.clipboard_text_view); //load from xml
myCTV.setCopyListener(new CopiedInterface(){ //set interface
@Override
public void textHasCopied(ClipboardTextView clipboardTextView, String stringCopied, boolean hasSucces) {
SimbiLog.print(stringCopied, hasSucces); //show the value
}
});
###Remote Image View ####A remote image view tha make cache of downloaded image
//Do not need java code
<simbio.se.sau.view.RemoteImageView
xmlns:sau="http://schemas.android.com/apk/res-auto"
android:id="@+id/remote_imageview_working"
android:layout_width="@dimen/zero"
android:layout_height="match_parent"
android:layout_weight="1"
sau:defaultImage="@drawable/remote_image_default"
sau:errorImage="@drawable/remote_image_fail"
sau:imageUrl="https://any.png" />
//But you can use java code too
RemoteImageView remoteImageView = new RemoteImageView(context); //create a view or load from xml if prefers
remoteImageView.setImageUrl("https://any.png"); //any image url
remoteImageView.setErrorImage(R.drawable.remote_image_fail); //a local image resource to be used when download fails
remoteImageView.setDefaultImage(R.drawable.remote_image_default); //a local image resource to be used when download is not ended
remoteImageView.deleteCachedImage(); //Maybe you wants delete the cached image
remoteImageView.start(); //Starts download proccess
###Share
SimbiShare.shareWithChooser(this, R.string.hello_world, R.string.app_name, R.string.action_share); //an easy way to share with android native choose method
SimbiShare.shareWithChooser(this, "content", "subject", "title"); //you can use Strings too
###Toast maker
ToastMaker.toast(getApplicationContext(), "Some Text"); //show toasts easily
ToastMaker.toast(getApplicationContext(), R.string.hello_world); //use strings xml resources too
ToastMaker.toast(getApplicationContext()); // Toast just a "here"
###Resize Animation
ResizeAnimation resizeAnimation = new ResizeAnimation(view, toHeight, toWidth); //Resive the view to new height and width
resizeAnimation.setDuration(resizeDuration); //set the duration of animation
resizeAnimation.setAnimationListener(this); //set the listener if you want
view.startAnimation(resizeAnimation); //start it
###SQLite ####powered by Shiva
//To use SQLite easily extends our class DatabaseHelper like bellow
public class SqlManager extends DatabaseHelper {
public SqlManager(Context context, DatabaseDelegate delegate) {
super(context, delegate, "yourDatabase.sqlite", 1);
}
@Override
protected List<Class<?>> getModelsToBeCreatedOnDatabase() {
//create this list to add the classes that you want save on database
List<Class<?>> clazzez = new ArrayList<Class<?>>();
//add any classes that you want
clazzez.add(SqlFooModel.class);
return clazzez;
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
//normal onUpgrade of android sqlite
}
}
//before we use, we need create a delegate. You can implements DatabaseDelegate interface on your own class too
DatabaseDelegate delegate = new DatabaseDelegate() {
@Override
public void onRequestSuccess(DatabaseHelper databaseHelper, int requestId, Object object) {
//do anything that you want, the object is the return os a select for example
}
@Override
public void onRequestFail(DatabaseHelper databaseHelper, int requestId, Exception exception) {
//if fails
}
};
//now we can use our sqlite easily
new SqlManager(getApplicationContext(), this).insert(new SqlFooModel(), REQUEST_ADD); //insert
new SqlManager(getApplicationContext(), delegate).select(SqlFooModel.class, REQUEST_LOAD); //select
new SqlManager(getApplicationContext(), this).delete(object, REQUEST_DELETE); //delete
new SqlManager(getApplicationContext(), this).clearTable(REQUEST_DELETE_ALL, SqlFooModel.class); //clear table
###Open Documents
new ActivityUtils(this).openDocumentWithCorrectActivity("/path/to/text.txt"); //open the txt file with correct intent
new ActivityUtils(this).openDocumentWithCorrectActivity("/path/to/doc.ods"); //works to any file format since the android device has the correctly app to open this file format
new ActivityUtils(this).openDocumentWithCorrectActivity("/path/to/music.ogg"); //just more one example
###Array Adapter ####to be used on list views or fragments adapters
//first extends the class AbstractAdapter and send the type of object used by your adapter
public class MyAdapter extends AbstractAdapter<FooModel> {
public interface MyAdapterDelegate extends IAbstractAdapter<FooModel> {
}
public SqlListViewAdapter(Context context, MyAdapterDelegate delegate) {
super(context, delegate, R.layout.your_xml_layout);
}
}
//it's all but probably you want edit your views so you can override getView method like:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View rootView = super.getView(position, convertView, parent);
// do anything with your rootView, to get views inside use rootView.findViewById(id);
return rootView;
}
###Copy files from assest to an usable folder
ActivityUtils activityUtils = new ActivityUtils(this);
// we need files on sdcard, so we go copy from assests to a folder called sauSample on sdcard
path = Environment.getExternalStorageDirectory().getAbsolutePath() + "/sauSample/";
try {
activityUtils.copyAssetsFilesToFolder(path);
} catch (Exception e) {
ToastMaker.toast(getApplicationContext(), e);
}
###Get primary user email
//you need the follow permission:
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
//and you need the follow code
DeviceInformationsManager dim = new DeviceInformationsManager(context)
String email = dim.getPrimaryUserEmailOrNull()
###Null or Empty validation
NullOrEmpty.verify(""); //returns true
NullOrEmpty.verify("not empty"); //returns false
NullOrEmpty.verify(null); //returns true
ArrayList<Object> list = null;
NullOrEmpty.verify(list); //returns true
list = new ArrayList<Object>();
NullOrEmpty.verify(list); //returns true
list.add(new Foo());
NullOrEmpty.verify(list); //returns false
####SAU have a lot of more things, see the examples :D
