Simple Splash Screen

Hello my Android Hub ...

Today I am here with you to tell you, How to make simple Splash Screen for android application ?

Do you know what is Splash Screen ????

Answer :  Splash screen is the main application screen which runs initially when you run application. This screen will run first after that you will go to next activity.

Example : Most of you are using "paytm" application, whenever you open that app, you will find there first screen with its logo and other thing. It will stay on screen till the program sets the seconds. Usually splash screen will take 3-5 second max. 

How to implement it through Android Studio ???? 

• Create a new Android Studio Project. 
• Take one empty black screen.

Now, In your activity.xml file, you can set picture or text or logo whatever you want, put it over there. Here I'm sharing a one snapshot of my work. 

Now, you only need to define small line of code in your activity.java file. 

Here I'm sharing that code that you should put in your project.

public class SplashActivity extends AppCompatActivity { private static int time_out = 2000; @Override public void onBackPressed() { //super.onBackPressed(); finish(); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); this.requestWindowFeature(Window.FEATURE_NO_TITLE); this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); this.requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.activity_splash); new Handler().postDelayed(new Runnable() { @Override public void run() { Intent i=new Intent(SplashActivity.this,LoginActivity.class); startActivity(i); finish(); } },time_out); } }

For that you have to implement one java class filesa and use that file in your activity.xml file.

The java class files is as bellow.


RoundedImageView.java

package com.tricktechs.makemyplace.Activity;

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

/**

public class RoundedImageView extends ImageView {

    public RoundedImageView(Context ctx, AttributeSet attrs) {
        super(ctx, attrs);
    }

    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }
        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth(), h = getHeight();

        Bitmap roundBitmap = getRoundedCroppedBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);

    }

    public static Bitmap getRoundedCroppedBitmap(Bitmap bitmap, int radius) {
        Bitmap finalBitmap;
        if (bitmap.getWidth() != radius || bitmap.getHeight() != radius)
            finalBitmap = Bitmap.createScaledBitmap(bitmap, radius, radius,
                    false);
        else
            finalBitmap = bitmap;
        Bitmap output = Bitmap.createBitmap(finalBitmap.getWidth(),
                finalBitmap.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, finalBitmap.getWidth(),
                finalBitmap.getHeight());

        paint.setAntiAlias(true);
        paint.setFilterBitmap(true);
        paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor("#BAB399"));
        canvas.drawCircle(finalBitmap.getWidth() / 2 + 0.7f,
                finalBitmap.getHeight() / 2 + 0.7f,
                finalBitmap.getWidth() / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
        canvas.drawBitmap(finalBitmap, rect, rect, paint);

        return output;
    }
}

Know, How to implement this java file in your xml file. 

Just see this bellow code. 

<com.tricktechs.makemyplace.Activity.RoundedImageView

            android:id="@+id/iv_pic"

            android:layout_width="80dp"

            android:layout_height="80dp"
