#Awesome Binder for Android "Android UI Programming has never been this easy!"
"No pain, Yes gain"

##What is it? AwesomeBinder is a two-way databinding library ready-to-hand. It is aimed to present an AngularJS-like experience to Android Developers. In other words, you can create a fully reactive layout without painful, annoying Java UI coding.

##What does it do? AwesomeBinder does many things, and that's why it is AWESOME.

###1. Data Binding In One Line

With Vanilla Android

// MyActivity.java
public class MyActivity extends Activity {
  ...
  public void onCreate(...) {
    setContentView(R.layout.simple);
    button = (Button)findViewById(R.id.button);
    textView = (TextView)findViewById(R.id.textView);
    editText = (EditText)findViewById(R.id.editText);
    checkBox = (CheckBox)findViewById(R.id.checkBox);
    button.setText("I");
    textView.setText("Really");
    editText.setText("Hate");
    checkBox.setText("This");
  }
}

<!-- simple.xml -->
<LinearLayout ...>
  <Button ...
    android:id="@+id/button" />
  <TextView ...
    android:id="@+id/textView" />
  <EditText ...
    android:id="@+id/editText" />
  <CheckBox ...
    android:id="@+id/checkBox" />
</LinearLayout>

With AwesomeBinder

// MyActivity.java
public class MyActivity extends Activity {
  public void onCreate(...) {
    binder = AwesomeBinder.bind(this, R.layout.simple)
        .set("{'str1':'This', 'str2':'Seems',
            'str3': 'Much', 'str4': 'Better'}");
  }
}

<!-- simple.xml -->
<LinearLayout ...>
  <Button ...
    app:content="str1" />
  <TextView ...
    app:content="str2" />
  <EditText ...
    app:content="str3" />
  <CheckBox ...
    app:content="str4" />
</LinearLayout>

###2. Reactive UI

<!-- reactive.xml -->
<LinearLayout ...>
  <EditText ...
    app:model="input" />
  <TextView ...
    app:content="input" />
</LinearLayout>

###3. Function Binding

// MyActivity.java
public class MyActivity extends Activity {
  public void onCreate(...) {
    binder = AwesomeBinder.bind(this, R.layout.simple);
  }
  
  public String greet() {
    return "Hello, " + (String)binder.get("name");
  }
}

<!-- reactive.xml -->
<LinearLayout ...>
  <EditText ...
    app:model="name" />
  <TextView ...
    app:content="greet()" />
</LinearLayout>

##Contribution Feel free to fork. Since it is pre-pre-alpha there are bunch of things to implement and improve.

##Licenses I'm considering which license to use.
