我刚刚注意到在我的应用程序中，当我将应用程序留在后台一段时间'并重新打开时，我使用了带有片段的操作栏。各种布局混合发生混乱......可能是由于我如何配置选项卡的类。我在这里写下来源：
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.
}
}
当我将应用程序留在后台一段时间时会发生这种情况'同时我使用其他......我只是无法弄清楚它取决于什么......内存？我在代码中做错了吗？这是相同的屏幕截图：http:
