Android Uygulaması - Zaten yüklenmişse her aktivite için son parçayı alın

Question

Aslında birden fazla etkinlikte (araç çubuğumun her simgesi için açık) bir uygulamamız var, ayrıca bu etkinliklerin son parçasını gösterme olanağına sahip olmak istiyorum. Kullanıcı zaten önceden açmışsa yığın. Aşağıdaki tüm Temel Aktivite sınıfımda görebileceğiniz gibi (tüm etkinliklerim için genişletiyorum), yığına parçaları zaten ekliyorum.

Bu

benim sınıftır:

public class BaseActivity extends AppCompatActivity { 

private final String TAG = "BaseActivity"; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_base); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    return false; 
} 

@Override 
public boolean onOptionsItemSelected(MenuItem item) { 

    return super.onOptionsItemSelected(item); 
} 

public void setImageLoaderConfig(Context context) { 
    DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder() 
      .cacheInMemory(true).cacheOnDisk(true) 
      .resetViewBeforeLoading(true) 
      .build(); 
    ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(context) 
      .defaultDisplayImageOptions(defaultOptions) 
      .build(); 
    ImageLoader.getInstance().init(config); 
} 

public void initToolBar() { 
    LinearLayout linearLayout = (LinearLayout) findViewById(R.id.toolbar_layout); 
    Toolbar toolbar = (Toolbar) linearLayout.findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 
    if (toolbar != null) { 
     initToolbarOnClickListener(); 
    } 
} 

private void initToolbarOnClickListener() { 

    (findViewById(R.id.toolbar_relativelayout_news)).setOnClickListener(new View.OnClickListener() {

kullanarak FrameLayout güncel fragman (sonuncusu eklendi) alabilirsiniz için şimdiden

Teşekkür:

Fragment fragment = getSupportFragmentManager().findFragmentById(layoutId); //layoutId is id of FrameLayout
