Step 4:-  Create a Drawable  file drawable_amber_gradient.xml  Right Click on ==> drawable ==>New ==> drawable resource file .

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient
        android:angle="135"
        android:endColor="@color/colorAmber_A400"

Step 9:- Open your xml file  activity_log_in.xml.  and add these code in your xml file .

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <CheckBox
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Remember Me"
            android:layout_marginRight="10dp"
            android:layout_marginLeft="10dp"
            android:layout_marginBottom="10dp"

            android:text="Forget Password"
            android:layout_marginRight="10dp"
            android:layout_marginLeft="10dp"
            android:layout_marginBottom="10dp"
            android:layout_marginTop="0dp"
            android:gravity="center"
            android:textColor="@color/white"
            android:drawableLeft="@drawable/ic_lock_outline_white_24dp"
            android:drawablePadding="6dp"
            android:padding="4dp"/>
    </LinearLayout>

    <Button

</LinearLayout>
</RelativeLayout>

Step 10:-  Open your java class Login.java and a cope add these code.

public class LogInActivity extends AppCompatActivity {
    private AnimationDrawable animationDrawable;
    RelativeLayout relativelayout;
    Button LoginBtn,RegBtn;
    EditText UserName,UserPass;
    TextView ForgotPass;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_log_in);
       relativelayout=(RelativeLayout)findViewById(R.id.RelativeLayout);
        // initializing animation drawable by getting background from RelativeLayout layout
        animationDrawable = (AnimationDrawable) relativelayout.getBackground();
        // setting enter fade animation duration to 5 seconds
        animationDrawable.setEnterFadeDuration(5000);
        // setting exit fade animation duration to 2 seconds
        animationDrawable.setExitFadeDuration(2000);
        UserName=(EditText)findViewById(R.id.UserEmail);
        UserPass=(EditText)findViewById(R.id.UserPassword);
        LoginBtn=(Button)findViewById(R.id.Log_Btn);
        RegBtn=(Button)findViewById(R.id.Reg_Btn);
        RegBtn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(LogInActivity.this,Registration.class);
                startActivity(intent);
                finish();
            }
        });
        ForgotPass=(TextView)findViewById(R.id.Forgot_Pass);

    }
    @Override
    protected void onResume() {
        super.onResume();
        if (animationDrawable != null && !animationDrawable.isRunning()) {
            // start the animation
            animationDrawable.start();
        }

    }

    @Override
    protected void onPause() {
        super.onPause();
        if (animationDrawable != null && animationDrawable.isRunning()) {
            // stop the animation
            animationDrawable.stop();
        }
    }
}

complete that run you app and test it.
