如何在碎片中進行交易？

Question

我有片段A >> B >> C >> D >> E。當我從一個遍歷到B I使用下面的代碼

Fragment fragment = new B(); 
FragmentManager fragmentManager = ((FragmentActivity)activity).getSupportFragmentManager(); 
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); 
fragmentTransaction.replace(R.id.frame_container, fragment, "B").addToBackStack("A").commit(); 

同樣地，對於B到C和....

如何可以從d移動到A的情況下直接將C.？

請任何幫助，將不勝感激。其他答案是混淆的方式。沒有人在爲我工作。

Answer 1

Use this 


Fragment fragment = new B(); 
FragmentManager fragmentManager = getFragmentManager(); 
fragmentManager.beginTransaction().replace(R.id. frame_container, fragment).commit(); 




In D 

@Override 
public boolean onKeyDown(int keyCode, KeyEvent event) { 
    if (keyCode == KeyEvent.KEYCODE_BACK) { 
     Fragment fragment = new D(); 
     FragmentManager fragmentManager = getFragmentManager(); 
     fragmentManager.beginTransaction().replace(R.id. frame_container, fragment).commit(); 
    } 
    return super.onKeyDown(keyCode, event); 
}
