问题 I knew that parcelable are hide something secret, but didn't thought that i need to know them, unitl now. Here is the code i had before: ... parcel.writeBooleanArray(new boolean[]{booleanValue1, booleanValue2, booleanValue3}); .... boolean[] booleans = new boolean[3]; in.readBooleanArray(booleans); ... Somehow it stops working on many devices except my, so i can't reproduce it. Then i decided to change it to: ... parcel.writeBooleanArray(new boolean[]{booleanValue1}); parcel.writeBooleanArray

Why is my activity crashing when hitting the home button?

问题 At this point I'm quite frustrated. I've been researching this for a few days and cannot even isolate anything beyond a cursor problem. I am extending ListActivity and using startManagingCursor(newcursor) in the OnCreate method. Here is the code (the database is already filled) that runs and crashes upon hitting the home button: private void loadAlbums() { try { newcursor = mDbHelper.getAlbumTitlesCursor(); dbalbumadapter = new AlbumListCursorAdapter(this, newcursor); setListAdapter

Why doesn't catching Exception catch RuntimeException?

由 此生再无相见时 提交于 2019-11-28 04:52:25
This is very odd to me. RuntimeException inherits from Exception , which inherits from Throwable . catch(Exception exc) { /* won't catch RuntimeException */ but catch(Throwable exc) { /* will catch RuntimeException */ I know RuntimeException is special in that it's unchecked. But to my understanding that applies just to whether exceptions have to be declared, not whether they are caught. And even then, I don't know why this logic would break on catching Throwable. This is pretty relevant to me since I have a situation where RuntimeExceptions can be thrown in a terminal operation. I'm not sure

Please explain RuntimeException in Java and where it should be used

由 自闭症网瘾萝莉.ら 提交于 2019-11-28 04:25:54
I am following this great discussion at SO, titled: The case against checked exceptions , but I am unable to follow where exactly RuntimeException should be used and how it is different from normal Exceptions and its subclasses. Googling gave me a complex answer, that is, it should be used to deal with programming logic errors and should be thrown when no Exception should normally occur, such as in the default block of switch-case construct. Can you please explain RuntimeException in greater detail here. Thanks. I am unable to follow where exactly RuntimeException should be used That's

How to wrap checked exceptions but keep the original runtime exceptions in Java

由 ≡放荡痞女 提交于 2019-11-27 23:19:15
问题 I have some code that might throw both checked and runtime exceptions. I'd like to catch the checked exception and wrap it with a runtime exception. But if a RuntimeException is thrown, I don't have to wrap it as it's already a runtime exception. The solution I have has a bit overhead and isn't "neat": try { // some code that can throw both checked and runtime exception } catch (RuntimeException e) { throw e; } catch (Exception e) { throw new RuntimeException(e); } Any idea for a more elegant

Popup Menu in custom ListView

由 泄露秘密 提交于 2019-11-27 20:16:19
What I want to achieve: I have a custom ListView adapter. To each Listitem I want to add a popup menu, pretty similar to the ListView in the current Google Play application. This is what I tried: Most of my code comes from this Android sample samples\android-19\ui\ActionBarCompat-ListPopupMenu CustomFragmentPageAdapter.java : // create new fragment mCustomFragment = CustomFragment.newInstance(position); CustomFragment.java public class CustomFragment extends ListFragment implements View.OnClickListener{ ... @Override public void onClick(final View v) { v.post(new Runnable() { @Override public
