【中文标题】Activity 已泄露窗口，Dialog【英文标题】：Activity has leaked window, Dialog 【发布时间】：2016-06-26 20:00:14 【问题描述】：我有一个包含设备列表的活动A，当我单击此列表中的某个项目时，另一个活动称为（活动B）。
activityB是一个tabActivity，使用viewPager来展示不同的fragment。 Activity 有一个 MenuItem 来检查设备。单击 MenuItem 时会出现一个对话框。但是我创建了另一个类来显示对话框，因为我希望这个对话框显示在不同的片段中。
问题是，Dialog 出现了，但是 Activity 泄漏了，然后结束了。
怎么办？
活动B：
@Override
protected void onCreate(Bundle savedInstanceState)
super.onCreate(savedInstanceState);
setContentView(R.layout.tab_activity);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
equipment = (Equipment) getIntent().getExtras().getSerializable("equipment");
viewPager = (ViewPager) findViewById(R.id.viewpager);
viewPager.addOnPageChangeListener(this);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
tag = "FragA";
private void setupViewPager(ViewPager viewPager)
Bundle bundle = new Bundle();
bundle.putSerializable("equipment", equipment);
FragmentA fragmentA = new FragmentA();
fragmentA.setArguments(bundle);
FragmentB fragmentB = new FragmentB();
fragmentB.setArguments(bundle);
FragmentC fragmentC = new FragmentC();
fragmentC.setArguments(bundle);
adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(fragmentA, "FragA");
adapter.addFragment(fragmentB, "FragB");
adapter.addFragment(fragmentC, "FragC");
viewPager.setAdapter(adapter);
class ViewPagerAdapter extends FragmentPagerAdapter
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager)
super(manager);
@Override
public Fragment getItem(int position)
return mFragmentList.get(position);
@Override
public int getCount()
return mFragmentList.size();
public void addFragment(Fragment fragment, String title)
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
@Override
public CharSequence getPageTitle(int position)
return mFragmentTitleList.get(position);
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels)
@Override
public void onPageSelected(int position)
index = viewPager.getCurrentItem();
if (index == 0)
tag = "FragA";
else if (index == 1)
tag = "FragB";

tag = "FragC";
invalidateOptionsMenu();
@Override

Intent intent = new Intent(this, MainActivity.class);
startActivity(intent);
@Override

return false;
@Override
public boolean onQueryTextChange(String newText)
switch (index)
case 0:
FragmentA fragmentA = new FragmentA() adapter.getItem(index);
if (fragmentA != null)
fragmentA.refreshFragmentA(newText);
return false;
case 1:
FragmentB fragmentB = new FragmentB() adapter.getItem(index);
if (fragmentB != null)
fragmentB.refreshFragmentB(newText);
return false;
return false;
@Override
public boolean onCreateOptionsMenu(Menu menu)
getMenuInflater().inflate(R.menu.alarm, menu);
mCheckedItem = menu.findItem(R.id.action_check_equipment_final);
mBackupSettings = menu.findItem(R.id.enable_backup_final);
MenuItem searchItem = menu.findItem(R.id.menu_item_search_alarm);
mSearchItem = searchItem;
mSearchView = (SearchView) MenuItemCompat.getActionView(mSearchItem);
mSearchView.setOnQueryTextListener(this);
FragmentC fragmentC = (FragmentC) adapter.getItem(2);
if (fragmentC != null && fragmentC.isVisible() && index == 2)
String backup = equipmentInfoFragment.verifyBackup();
switch (backup)
case "enable":
mBackupSettings.setTitle(getResources().getString(R.string.disable_backup));
break;
case "disable":
mBackupSettings.setTitle(getResources().getString(R.string.enable_backup));
break;

mCheckedItem.setVisible(true);
mBackupSettings.setVisible(false);
return true;

mCheckedItem.setVisible(true);
mBackupSettings.setVisible(false);
return true;
case 2:
mSearchItem.setVisible(false);
mCheckedItem.setVisible(true);
mBackupSettings.setVisible(true);
return true;
default:
return super.onCreateOptionsMenu(menu);
@Override
public boolean onOptionsItemSelected(MenuItem item)
switch (item.getItemId())
case R.id.action_check_equipment_final:
CheckEquipment checkEquipment = new CheckEquipment(this);
checkEquipment.StarCheckEquipment(TabActivity.this, equipment);
case android.R.id.home:
finish();
return true;
case R.id.enable_backup_final:
EquipmentInfoFragment equipmentInfoFragment = (EquipmentInfoFragment) adapter.getItem(2);
equipmentInfoFragment.startEnableBackup();

具有对话框的类：

【问题讨论】：
我编辑了问题 【参考方案1】：我认为您应该将EquipmentDialogInner 从CheckEquipment 中取出并使其本身成为一个类（新文件等），而不是将其作为CheckEquipment 中的内部类。
然后您可以更改您的onOptionsItemSelected，如下所示：
switch (item.getItemId())
case R.id.action_check_equipment_final:
EquipmentDialogInner dialog = new EquipmentDialogInner(this);
dialog.setCancelable(false);
dialog.show();
case android.R.id.home:
finish();
return true;
case R.id.enable_backup_final:
EquipmentInfoFragment equipmentInfoFragment = (EquipmentInfoFragment) adapter.getItem(2);
equipmentInfoFragment.startEnableBackup();
