    How to create basic animations in android : In this blog i will show you how to create simple shake animation in android.First create a anim folder in res/anim in the android project. Create a xml file in it sopy the following code in it

    <translate xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:fromXDelta="0"
        android:interpolator="@anim/cycle&#95;7"
        android:toXDelta="10" />
    

    Create another xml file in android cycle_7.xml copy the following code:

    <cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android"
        android:cycles="7" />
    

    Then in the activity in which you want to show the animation copy the following code:

    import java.util.ArrayList;
    
    
    
    import android.app.Activity;
    import android.content.Intent;
    import android.os.AsyncTask;
    import android.os.Bundle;
    import android.view.KeyEvent;
    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.view.inputmethod.EditorInfo;
    import android.widget.Button;
    import android.widget.EditText;
    import android.widget.TextView;
    import android.widget.TextView.OnEditorActionListener;
    import android.widget.Toast;
    public class LoginActivity extends Activity implements AnimationListener {
        Animation anim;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.login);
    
            // Edit Text for username and password
            final EditText txtUserName = (EditText) findViewById(R.id.txtUsername);
            final EditText txtPassword = (EditText) findViewById(R.id.txtPassword);
    
            // set animation
            // to change animation change R.anim.bounce to R.anim.shake
            anim = AnimationUtils.loadAnimation(getApplicationContext(),
                    R.anim.bounce);
    
            // login button
            Button btnLogin = (Button) findViewById(R.id.btnLogin);
            btnLogin.setOnClickListener(new OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    String username = txtUserName.getText().toString();
                    String password = txtPassword.getText().toString();
                    try {
                        if (username.equals("")) {
                            txtUserName.setError("Username is required");
                            txtUserName.startAnimation(anim);
                        }
                        if (password.equals("")) {
                            txtPassword.setError("Password is required");
                            txtPassword.startAnimation(anim);
                        }
                        if (password.length() < 6) {
                            txtPassword
                                    .setError("Password must be 6 character long");
                            txtPassword.startAnimation(anim);
    
                        }
    
                    } catch (Exception e) {
                        Toast.makeText(LoginActivity.this, e.getMessage(),
                                Toast.LENGTH&#95;LONG).show();
                    }
                    LoginASYNC login = new LoginASYNC();
                    login.execute(new String[] { ServerUrl.BASE&#95;URL });
                }
    
            });
    txtUserName.setOnEditorActionListener(new OnEditorActionListener() {
                @Override
                public boolean onEditorAction(TextView v, int actionId,
                        KeyEvent event) {
                    boolean handled = false;
                    if (actionId == EditorInfo.IME&#95;ACTION&#95;SEND) {
                        // do the login
                        System.out.println("send uiser");
                        Toast.makeText(LoginActivity.this, "login clicked",
                                Toast.LENGTH&#95;LONG).show();
                        handled = true;
                    }
                    return handled;
                }
            });
    
            txtPassword.setOnEditorActionListener(new OnEditorActionListener() {
                @Override
                public boolean onEditorAction(TextView v, int actionId,
                        KeyEvent event) {
                    boolean handled = false;
                    if (actionId == EditorInfo.IME&#95;ACTION&#95;SEND) {
                        // do the login
                        System.out.println("send pass ");
                        Toast.makeText(LoginActivity.this, "login clicked",
                                Toast.LENGTH&#95;LONG).show();
                        handled = true;
                    }
                    return handled;
                }
            });
    
            TextView forget = (TextView) findViewById(R.id.forget&#95;password);
            forget.setOnClickListener(new OnClickListener() {
    
                @Override
                public void onClick(View v) {
                    // TODO Auto-generated method stub
                    startActivity(new Intent(LoginActivity.this,
                            Forget&#95;Password.class));
                }
            });
        }
    
        @Override
        public void onAnimationEnd(Animation animation) {
            // TODO Auto-generated method stub
    
        }
    
        @Override
        public void onAnimationRepeat(Animation animation) {
            // TODO Auto-generated method stub
    
        }
    
        @Override
        public void onAnimationStart(Animation animation) {
            // TODO Auto-generated method stub
    
        }
    }
    

    Hope the code helps.
