LouisLam's Lazy Library for Android.

(Sorry for my poor english)

Why we need the library?

Every single time, while i just wanted to pop out a simple alert dialog and I forgot how to create. Then I kept googling the code. Once I found that the code is very long. So I wonder why we cannot have a simple way just like Javascript's alert(). It is easy to remember and just one line of code!

So I decided to create the library to do that.

L.alert(this, "Hi.");

Without the library to do the same thing:

AlertDialog.Builder b = new AlertDialog.Builder(this);
b.setMessage("Hi.");
b.setCancelable(false);
b.setPositiveButton("OK", new OnClickListener() {
	@Override
	public void onClick(DialogInterface dialog, int which) {
		dialog.dismiss();
	}
});
b.show();

It is more simple, right?

Of course, the library contains other lazy functions. Check examples below.

Descriptions

There are example usage for the methods.

"L" means LouisLam or Lazy.

What's News

20 Sept 2014 (v1.1)

  • Lazy Storage (Class name: LStorage). You can store Sting, Int, Float or Boolean now.

Installation

  1. Download the jar file.

  2. Import the jar to your android project.

  3. Import the package in your Class/Activity.

     import net.louislam.android.*;
    
  4. Done.

Assumption

In all examples, "this" means Activity/Context object.

Lazy Alert Dialog

I love this so much. <3

Usage:

L.alert(this, "I am Louis.");

Alert Dialog with callback:

L.alert(this, "Boss: Where is Louis!?", new OnClickListener() {
	@Override
	public void onClick(DialogInterface dialog, int which) {
		L.alert(MainActivity.this, "Louis: here :( ");
	}
});

Lazy Input Dialog

Example Usage:

L.inputDialog(this, "What is your name?", new InputListener() {
 
 	public void inputResult(String value) {
 		String name = value;
 		L.alert(MainActivity.this, "My name is: " + name);
	}
 
 });

With default value (add a parameter to the last)

L.inputDialog(this, "What is your name?", new InputListener() {
 
 	public void inputResult(String value) {
 		String name = value;
 		L.alert(MainActivity.this, "My name is: " + name);
	}
 
 }, "Louis");

Lazy Confirmation Dialog

Example Usage:

L.confirmDialog(this, "Are you sure?", new OnClickListener () {
	@Override
	public void onClick(DialogInterface dialog, int which) {
		// Do something here if clicked "Yes"	
	}		
});

For those activity classes already implements OnClickListener

public class LoginActivity extends Activity implements OnClickListener {
	....
  	public void quit() {
		L.confirmDialog(this, "Are you sure?");
 	}
	....
}

Lazy Loading Dialog

Example Usage:

ProgressDialog loadingDialog = L.progressDialog(this, "Loading...");

Dismiss the dialog:

loadingDialog.dismiss();

Lazy Log

simply methods for LogCat

Example Usage:

L.log("[Debug] the activity is loaded.");

Disable/Enable Log globally

L.enableLog(false);

Lazy String Storage

Store

L.storeString(this, "username", "louislam");

Retrieve / Get

L.getString(this, "username");

Lazy Start Activity

Example Usage:

L.startActivity(this, "LoginActivity");

or

L.startActivity(this, LoginActivity.class);

or (For result)

1314 = Request Code

L.startActivity(this, LoginActivity.class, 1314);

or (starting an activity for result with bundle)

Bundle bundle = new Bundle();
L.startActivity(this, LoginActivity.class, 1314, bundle);
