How do I get an Image to Fade at the start of an Android app without buttons

Question

I am trying to get a Image to fade at the start of an application without having to press a button. I have been looking around but it seems as if for some reason that people only know how to make it so that you need a button to make the image or object to perform the animation. I do have a animation file ready. The problem is getting the image to fade without a button.

package android.example.verification;

import androidx.appcompat.app.AppCompatActivity;

import android.graphics.drawable.Drawable;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.WindowManager;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.ImageView;

public class MainActivity extends AppCompatActivity {

    private static final String TAG = "MainActivity";

    MediaPlayer mysong;
    private View image;
    ImageView imageView;
    Animation animation;
    private Object TitleScreen;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Log.d(TAG,"onCreate: started.");
        mysong = MediaPlayer.create(MainActivity.this, R.raw.bc);
        mysong.start();
        mysong.setLooping(true);

        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        //Logo
        int imageResource = getResources().getIdentifier("@drawable/logo", null, this.getPackageName());
        ImageView firstImage = (ImageView) findViewById(R.id.firstImage);
        firstImage.setImageResource(imageResource);
    }

    //Logo Fade Animation
    public void tapToFade(View view) {
        Button button = (Button)findViewById(R.id.firstImage);
        Animation animation = AnimationUtils.loadAnimation(this, R.anim.fade);
        button.startAnimation(animation);
    }

    //helps Music
    @Override
    protected void onPause() {
        super.onPause();
        mysong.release();
        finish();
    }

}

is your code even working? you are casting `R.id.firstImage` twice in your code to two different classes... can you describe more clearly what do you want to achievie? — snachmsm, Sep 03 '21 at 06:31

Firstly you can use Handler.postDelayed(Runnable, long) to run a code after a time delay (if you don't want to use a click event to start the animation). this code invokes the Runnable.run() method after 1000 milliseconds which starts the animation.

final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
     @Override
     public void run() {
          Button button = (Button)findViewById(R.id.firstImage);
          Animation animation = AnimationUtils.loadAnimation(this, R.anim.fade);
          button.startAnimation(animation);
     }
}, 1000);

Secondly you don't need to cast R.id.firstImage to specifically to Button to use the startAnimation, all classes extending the View class have this method.

what you want to do is called SplashScreen

Splash Screen will show an image when you open your App for a period of time(ex. 1000 ms or one second) then after that will display MainActivity .

You should create new activity called SpalshScreen then add this code in onCreate Method in SplashScreen.java

setContentView(R.layout.splash_layout);
new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            /* Create an Intent that will start the Main-Activity. */

            Intent intent = new Intent(this, MainActivity.class);
            startActivity(intent);
            finish();

        }
    }, 1000); //show this screen for 1 second
}

And then go to manifest you need to set spalshScreen as LAUNCHER .

<activity
android:name=".SplashActivity">
<intent-filter>
    <action android:name="android.intent.action.MAIN" />

    <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

that will show SplashScreen for 1 second and then will open MainActivity page.
