• Avoid write a class in each project you always use;
• Guarantee the organization of code using a specific structure;

Installation

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Documentation

Appeareance

This class contatins a lot of functions to change the appearance of your app. You should start by create an instance of it:

private Appearance appearance;

@Override
protected void onCreate(){
  appearance = new Appearance(this);
}

Change color of status bar

If you want to use your own color in status bar, you should use the follow code

appearance.changeColorOfStatusBar(R.color.myCustomColor);

Network

This class is used to handle events related to network

private Network network;

@Override
protected void onCreate(){
  network = new Network(this);
}

Check network connection

To check the network connection in that exactly moment, you can use the follow functions, which return a boolean:

if (network.isConnectedToNetwork()){
  // returned true, is connected
  Toast.makeText(context, "Is connected to network", Toast.LENGTH_SHORT).show();
}else{
  // returned false, isn't connected
  Toast.makeText(context, "Isn't connected to network", Toast.LENGTH_SHORT).show();
}

Code sctructure

In order to keep the organization of the code, there is some methods to do it

Basic functions

Always when is created a new activity or fragment, there are some methods that are always required. So i can easily override and create this methods implementing the BasicFunctions:

public class LoginActivity extends AppCompatActivity implements BasicFunctions {
    
    private Button loginButton
    private ArrayList<String> arrayListNames;
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);

	// call the methods
        findVisualElements();
        startPublicVariables();
        onClickListener();
    }

    @Override
    public void findVisualElements() {
	// find the elements of layout by id
	loginButton = findViewById(R.id.login_button);
	
    }

    @Override
    public void startPublicVariables() {
    	// start all public variables
        arrayListNames = new ArrayList();
    }

    @Override
    public void onClickListener() {
	// handle the click of buttons
        buttonLogin.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                login();
            }
        });
    }
}
