刷新一個片段android

Question

此代碼早些時候工作，但現在它突然停止工作。片段不會從父項活動中分離出來。

public void reLoadFragment(Fragment fragment) 
{ 
    Log.i(LogGeneratorHelper.INFO_TAG, "reloading fragment"); 
    // Reload current fragment 
    Fragment frg = null; 
    frg = getSupportFragmentManager().findFragmentByTag(fragment.getClass().getName()); 
    frg.onDetach(); 
    final FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 
    ft.detach(frg); 
    ft.attach(frg); 
    ft.commit(); 
    Log.i(LogGeneratorHelper.INFO_TAG, "reloading fragment finish"); 
} 

Answer 1

使用這YOUT主要活動：

frag_name frag_name = new frag_name(); 
        FragmentManager manager = this.getSupportFragmentManager(); 
        manager.beginTransaction().replace(R.id.youtframelayout, frag_name, frag_name.getTag()).commit(); 

它inicializes的fragment並在FrameLayout

你這樣的替換再片段:)

希望它可以替代它作品！ :)

Answer 2

你可以簡單地使用刷新

FragmentTransaction ft = getFragmentManager().beginTransaction(); 
ft.detach(this).attach(this).commit(); 

而且，你的情況，你可以做這樣的事情

public void reLoadFragment(Fragment fragment) 
{ 
    Log.i(LogGeneratorHelper.INFO_TAG, "reloading fragment"); 
    Fragment currentFragment = fragment; 
    if (currentFragment instanceof "FRAGMENT CLASS NAME") { 
     FragmentTransaction fragTransaction = (getActivity()).getFragmentManager().beginTransaction(); 
     fragTransaction.detach(currentFragment); 
     fragTransaction.attach(currentFragment); 
     fragTransaction.commit(); 
     Log.i(LogGeneratorHelper.INFO_TAG, "reloading fragment finish"); 
    } 
    else Log.i(LogGeneratorHelper.INFO_TAG, "fragment reloading failed"); 
} 

當前片段，

Answer 3

ft.detach()支持庫更新25.1.0後不工作。該解決方案更新後正常工作：

getSupportFragmentManager().beginTransaction().detach(oldFragment).commitNowAllowingStateLoss(); 
getSupportFragmentManager().beginTransaction().attach(oldFragment).commitAllowingStateLoss(); 

信用： Refresh or force redraw the fragment
