    text
    copied!<p>Noob Android developer here I'm more graphics than code but thought I'd start doing more coding. Anyway, I have some buttons on my main activity page and I want it so when the button is clicked it opens another class/activity. I've tried all the methods I've looked up and something is still not working, when I click the button in the emulator it just doesn't do anything, does't forcestop or anything just nothing, someone point me in the right direction please.</p> <p>Code from the main page where the button lives:</p> <pre><code>public class StartingPoint extends Activity { protected void onCreate(Bundle aim) { super.onCreate(aim); setContentView(R.layout.main); final Button bSL = (Button) findViewById(R.id.bSongList); bSL.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Intent SongList = new Intent(StartingPoint.this, SongList.class); StartingPoint.this.startActivity(SongList); } }); } } </code></pre> <p>Manifest</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="myname.appname" android:versionCode="1" android:versionName="1.0" &gt; &lt;uses-sdk android:minSdkVersion="10" /&gt; &lt;application android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@android:style/Theme.Black.NoTitleBar" &gt; &lt;activity android:name=".Splash" android:label="@string/app_name" android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" &gt; &lt;intent-filter&gt; &lt;action android:name="myname.appname.SPLASH" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;activity android:name=".StartingPoint" android:label="@string/app_name" &gt; &lt;intent-filter&gt; &lt;action android:name="myname.appname.STARTINGPOINT" /&gt; &lt;category android:name="android.intent.category.DEFAULT" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;activity android:name=".SongList" android:label="@string/app_name" &gt; &lt;intent-filter&gt; &lt;action android:name="myname.appname.SONGLIST" /&gt; &lt;category android:name="android.intent.category.DEFAULT" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;/application&gt; &lt;/manifest&gt; </code></pre> <p>-L</p> <pre><code>Last 3 lines of logcat just after clicking the button in question. 01-02 21:59:50.473: I/ActivityManager(75): Starting: Intent { cmp=myname.appname/.SongList } from pid 681 01-02 21:59:52.953: I/ActivityManager(75): Displayed myname.appname/.SongList: +2s351ms 01-02 21:59:58.565: D/dalvikvm(348): GC_EXPLICIT freed 8K, 55% free 2591K/5703K, external 1625K/2137K, paused 520ms </code></pre>
