Creating login animation like facebook android

Question

I want to create a login page (Like facebook android app) where the userid and password EditText fields are hidden. A logo is shown on the page which animates above

Answer 1

1st The facebook image goes up so you have to translate it from current position to top

Here android:fromYDelta is start position and android:toYDelta is end position in percentage i.e -30% and android:duration is in time i.e. 1 second

2nd Now attach a listener to check when animation is done 3rd Now Fade in your login box

here is the code

MinActivity.java

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.LinearLayout;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button startAnimation =(Button) findViewById(R.id.button1);
        final LinearLayout LoginBox = (LinearLayout) findViewById(R.id.LoginBox);
        LoginBox.setVisibility(View.GONE);
        startAnimation.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                Animation animTranslate  = AnimationUtils.loadAnimation(MainActivity.this, R.anim.translate);
                animTranslate.setAnimationListener(new AnimationListener() {

                    @Override
                    public void onAnimationStart(Animation arg0) { }

                    @Override
                    public void onAnimationRepeat(Animation arg0) { }

                    @Override
                    public void onAnimationEnd(Animation arg0) {
                        LoginBox.setVisibility(View.VISIBLE);
                        Animation animFade  = AnimationUtils.loadAnimation(MainActivity.this, R.anim.fade);
                        LoginBox.startAnimation(animFade);
                    }
                });
                ImageView imgLogo = (ImageView) findViewById(R.id.imageView1);
                imgLogo.startAnimation(animTranslate);

            }
        });

    }

}

And in the anim folder use these xml's

fade.xml

translate.xml

And the layout activity_main.xml
