Bir liste görünümü ile bir etkinlik var. Kullanıcı öğeyi tıklatın, maddenin "" açar: . viewer

List1.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {

        Intent nextScreen = new Intent(context,ServicesViewActivity.class);
        String[] Service = (String[])List1.getItemAtPosition(arg2);

        //Sending data to another Activity
        nextScreen.putExtra("data", datainfo);
        startActivityForResult(nextScreen,0);
        overridePendingTransition(R.anim.right_enter, R.anim.left_exit);
    }
});

Bu gayet iyi çalışıyor, ama actionbar tekrar oku app simgesinin yanındaki aktive olmuyor. Bir şey mi kaçırdım?

Emin olun, ActionBar Ev Düğmesine Faaliyeti etkin:

Android, API 5 :

@Override
public void onBackPressed() {
     ...
     super.onBackPressed();
}

ActionBarSherlock ve Uygulama-Uyumluluğu, API 7 :

@Override
public void onCreate(Bundle savedInstanceState) {
    ...
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}

Android, API 11 :

@Override
public void onCreate(Bundle savedInstanceState) {
    ...
    getActionBar().setDisplayHomeAsUpEnabled(true);
}

ActionBarActivity genişleten örnek MainActivity:

public class MainActivity extends ActionBarActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Back button
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        case android.R.id.home: 
            // API 5  solution
            onBackPressed();
            return true;

        default:
            return super.onOptionsItemSelected(item);
        }
    }
}

Bu şekilde istediğiniz tüm faaliyetler backpress olabilir.

Android, API 16 :

AndroidManifest.xml:

<application ... >
    ...
    <!-- The main/home activity (it has no parent activity) -->
    <activity
        android:name="com.example.myfirstapp.MainActivity" ...>
        ...
    </activity>
    <!-- A child of the main activity -->
    <activity
        android:name="com.example.myfirstapp.DisplayMessageActivity"
        android:label="@string/title_activity_display_message"
        android:parentActivityName="com.example.myfirstapp.MainActivity" >
        <!-- The meta-data element is needed for versions lower than 4.1 -->
        <meta-data
            android:name="android.support.PARENT_ACTIVITY"
            android:value="com.example.myfirstapp.MainActivity" />
    </activity>
</application>

ActionBarActivity uzanır *örnek 16*:

public class MainActivity extends ActionBarActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // Back button
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
        // Respond to the action bar's Up/Home button
        case android.R.id.home:
            NavUtils.navigateUpFromSameTask(this);
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
