Question

I’ve just began on a new application and I added a button which in the past I’ve had no problem with but for some reason Its not working now. I’m just simply trying to teacher that button to another page. What do you think the problem is? (just ignore the spinners I haven’t set those up yet)

TextingprojectActivity

public class TextingprojectActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button tut1 = (Button) findViewById(R.id.tutorial1);
        tut1.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // TODO Auto-generated method stub

                startActivity(new Intent("practice.practice.TUTORIALONE "));
            }
        });
    }
}

Tutorial1 Java

public class TutorialOne extends Activity
{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.tutorial1);
    }

}

Answer 1

change your intent call like

Intent n = new Intent(TextingprojectActivity.this,TutorialOne.class);
        startActivity(n);

Also remove the intent-filter from the delaration of the rest activity from maniefst.

 <intent-filter>
            <action android:name="practice.practice.TUTORIALONE" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>

Change it to like…

 <application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity
        android:name=".TextingprojectActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity android:name=".TutorialOne"
        android:label="@string/app_name">

        </activity>
</application>
