ButterKnife | View Injection Android library Tutorial

In every application we use "findviewbyid" get view reference from xml. It could be very lazy task and we dont like at all but it is compulsory to do. Which is boilerplate for every developer. To overcome this problem, We need to use Butterknife library. It saves time and very easy to integrates in existing code.

In general

public class LoginActivity extends Activity {
    private Button mEmailSignInButton;
    private Button xyz;
    private EditText mPassword;

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        mEmailSignInButton = (Button) findViewById(R.id.email_sign_in_button);
        xyz = (Button) findViewById(R.id.xyz);
        mPassword = (EditText) findViewById(R.id.password);
    }
}

After use of ButterKnife.

public class LoginActivity extends Activity {
    @Bind(R.id.email_sign_in_button)
    Button mEmailSignInButton;
    @Bind(R.id.xyz)
    Button xyz;
    @Bind(R.id.password)
    EditText mPassword;

    @Override    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_login);
        ButterKnife.bind(this);
    }
}

To Use This Butterknife Just add gradle to your gradle.build file like this

   dependencies {
//  compile 'com.android.support:design:+'  compile fileTree(dir: 'libs', include: ['*.jar'])   

     compile 'com.jakewharton:butterknife:7.0.1' 

       }
