Create an application that will have spinner with list of animation names. On Selecting animation name, that animation should affect on the images displayed below.


MainActivity.java

package com.example.application10;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.view.animation.Animation;

import android.view.animation.AnimationUtils;

import android.widget.AdapterView;

import android.widget.AdapterView.OnItemSelectedListener;

import android.widget.ArrayAdapter;

import android.widget.ImageView;

import android.widget.Spinner;

public class MainActivity extends AppCompatActivity implements OnItemSelectedListener {

    Spinner spin;

    ImageView imgmaster;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        spin = (Spinner) findViewById(R.id.spinnereffect);

        imgmaster = (ImageView) findViewById(R.id.imageViewmaster);

        String[] effect={"Select Effect","Rotate","Alpha","Scale","Translate","Blink"};

        ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_spinner_dropdown_item,effect);

        spin.setAdapter(adapter);

        spin.setOnItemSelectedListener(this);

    }

    @Override

    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

        Animation anim = AnimationUtils.loadAnimation(this, R.anim.selecteffect);

        if (spin.getSelectedItem().equals("Rotate"))

            anim = AnimationUtils.loadAnimation(this, R.anim.rotate);

        else if (spin.getSelectedItem().equals("Alpha"))

            anim = AnimationUtils.loadAnimation(this, R.anim.alpha);

        else if (spin.getSelectedItem().equals("Scale"))

            anim = AnimationUtils.loadAnimation(this, R.anim.scale);

        else if (spin.getSelectedItem().equals("Translate"))

            anim = AnimationUtils.loadAnimation(this, R.anim.translate);

        else if (spin.getSelectedItem().equals("Blink"))

            anim = AnimationUtils.loadAnimation(this, R.anim.blink);

        imgmaster.startAnimation(anim);

    }

    @Override

    public void onNothingSelected(AdapterView<?> parent) {

    }

}
