我有横向模式的布局,左侧显示ListView,右侧显示FrameLayout.从列表中选择项目时,另一个片段将添加到FrameLayout
MyFragment myFragment = (MyFragment) fragmentManager.findFragmentById(R.id.myFrameLayout);
FragmentTransaction ft = fragmentManager.beginTransaction();
if (myFragment == null) {
myFragment = new MyFragment(uri);
ft.replace(R.id.myFrameLayout,playerFragment);
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_OPEN);
ft.commitAllowingStateLoss();
}
稍后我在列表视图中按删除并删除列表中的最后一项,我尝试删除片段以便不显示任何内容,但它不起作用,我的片段仍然在屏幕上.删除代码是：
MyFragment myFragment = (MyFragment) fragmentManager.findFragmentById(R.id.myFrameLayout); FragmentTransaction ft = fragmentManager.beginTransaction(); ft.remove(myFragment); ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_CLOSE); ft.commitAllowingStateLoss();
任何想法为什么它没有从视图中删除？
解决方法
@DaveJohnston我已经尝试过你的代码删除片段我刚刚模塑….谢谢:)
嘿,我不知道这是你的问题的解决方案,但你尝试这种方式它会工作：
YourFragment yourFrament;
//Add your Fragment
public void addYourFragment(){
yourFragment = new YourFragment();
FragmentTransaction transation = getSupportFragmentManager().beginTransaction();
transation.replace(R.id.yourFlowLayout,yourFragment);
transation.commit();
}
//Remove Fragment
public void removeYourFragment(){
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
if (yourFragment != null) {
transaction.remove(yourFragment);
transaction.commit();
transaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_CLOSE);
yourFragment = null;
}
}
