    text
    copied!<p>So I am a complete newb, and am currently taking an intro to Mobile Programming course in which we use Android (I have some experience with Java). I am trying to do a simple assignment which displays a text field and an image, and upon entering the correct "password" and pressing enter, the image changes.</p> <p>Should be so simple! But I am having a really hard time with this and can't figure out what I am doing wrong, even after doing a good bit of searching (I assume it is something super obvious and I'm missing it).</p> <p>Here is my code:</p> <pre><code>package CS285.Assignment1; import android.app.Activity; import android.os.Bundle; import android.widget.EditText; import android.view.KeyEvent; import android.view.View; import android.view.View.OnKeyListener; import android.widget.ImageView; public class DisplayImage extends Activity implements OnKeyListener{ private EditText enteredText; private String pass = "monkey"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); enteredText = (EditText)findViewById(R.id.passField); enteredText.setOnKeyListener(this); } public boolean onKey(View v, int keyCode, KeyEvent event) { // If the event is a key-down event on the "enter" button if ((event.getAction() == KeyEvent.ACTION_DOWN) &amp;&amp; (keyCode == KeyEvent.KEYCODE_ENTER)){ // Perform action on key press switchImage(); return true; } return false; } public void switchImage(){ if(enteredText.getText().toString() == pass){ ImageView imgView = (ImageView)findViewById(R.id.Image); imgView.setImageResource(R.drawable.marmoset); } } } </code></pre> <p>and my main.xml:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" &gt; &lt;TextView android:id="@+id/textPrompt" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="#ff993300" android:text="Please enter password to see my real picture:" &gt; &lt;/TextView&gt; &lt;EditText android:id="@+id/passField" android:layout_width="fill_parent" android:layout_height="wrap_content" &gt; &lt;/EditText&gt; &lt;ImageView android:id="@+id/Image" android:layout_width="fill_parent" android:layout_height="fill_parent" android:adjustViewBounds="true" android:src="@drawable/airplane" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>I thought at first that I was not properly extracting the String from "enteredText" so the comparison to the "password" wasn't happening correctly, but I have since tried just printing the enteredText and it works fine.</p> <p>Totally frustrated--Any help would be greatly appreciated!</p> <p>Daniel</p>
