我的操作栏有问题，我解释得很好。因此，如果我在一个选项卡上（选择说），如果 cliccassi 不小心使应用程序崩溃，我希望不会发生......但我无法理解。我将发布一些我在 TAB 配置的主要活动中放入的代码。
private class TabListener<T extends Fragment> implements ActionBar.TabListener {
private Fragment mFragment;
private final Activity mActivity;
private final String mTag;
private final Class<T> mClass;
public TabListener(Activity activity, String tag, Class<T> clz) {
mActivity = activity;
mTag = tag;
mClass = clz;
}
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
// Check if the fragment is already initialized
if (mFragment == null) {
// If not, instantiate and add it to the activity
mFragment = Fragment.instantiate(mActivity, mClass.getName());
ft.add(android.R.id.content, mFragment, mTag);
} else {
// If it exists, simply attach it in order to show it
ft.show(mFragment);
//ft.attach(mFragment);
}
}
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) {
if (mFragment != null) {
// Detach the fragment, because another one is being attached
// ft.detach(mFragment);
ft.hide(mFragment);
}
}
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) {
ft.replace(tab.getPosition(),mFragment);
// User selected the already selected tab. Usually do nothing.
}
}
