if else statement in android
<p>I was new in Android and found some good tutorials on the internet, so I tried a simple activity with an <code>if-else</code> statement. I'm trying "correct and wrong" prompt/<code>Toast</code>:</p>

<pre><code>Button page1 = (Button) findViewById(R.id.button2);
       page1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                final ImageView iv1 = (ImageView) findViewById(R.id.imageView1);
                if (iv1.equals(R.drawable.airplane1)) {
                    Toast.makeText(getApplicationContext(), "Correct",
                            Toast.LENGTH_SHORT).show();
                } else if (iv1.equals(R.drawable.airplane2)) {
                    Toast.makeText(getApplicationContext(), "Please put an answer",
                            Toast.LENGTH_SHORT).show();
                } else if (iv1.equals(R.drawable.airplane3)){
                    Toast.makeText(getApplicationContext(), "Wrong",
                            Toast.LENGTH_SHORT).show();
                }
            }

       });
</code></pre>

<p>I'm not sure what is wrong in my <code>if-else</code> statement but never prompts at all. I tried removing the <code>(iv1.equals(R.drawable.airplane3))</code> and <code>(iv1.equals(R.drawable.airplane2))</code> then it only shows the wrong Toast. I can't get seem to make the correct to prompt me.</p>

<p>Here is the full code of my class:</p>

<pre><code>public class MainActivity extends Activity {
private static final Random imagerandom = new Random();

private static final Integer[] Imagesnumber = 
    { R.drawable.airplane1, R.drawable.airplane2, R.drawable.airplane3, };
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Integer a = Imagesnumber[imagerandom.nextInt(Imagesnumber.length)];
    final ImageView iv = (ImageView) findViewById(R.id.imageView1);

    View nextButton = findViewById(R.id.button1);
    nextButton.setOnClickListener(new Button.OnClickListener() {
         public void onClick(View V) {
              int resource = Imagesnumber[imagerandom.nextInt(Imagesnumber.length)];
              iv.setImageResource(resource);
         }
    });
    Button page1 = (Button) findViewById(R.id.button2);
       page1.setOnClickListener(new View.OnClickListener() {
            public void onClick(View view) {
                final ImageView iv1 = (ImageView) findViewById(R.id.imageView1);
                if (iv1.equals(R.drawable.airplane1)) {
                    Toast.makeText(getApplicationContext(), "Correct",
                            Toast.LENGTH_SHORT).show();
                } else if (iv1.equals(R.drawable.airplane2)) {
                    Toast.makeText(getApplicationContext(), "Please put an answer",
                            Toast.LENGTH_SHORT).show();
                } else if (iv1.equals(R.drawable.airplane3)){
                    Toast.makeText(getApplicationContext(), "Wrong",
                            Toast.LENGTH_SHORT).show();
                }
            }

       });




}

}
