问题 Assume, I have a subclass of EditTextPreference called PasswordProtectedEditTextPreference. This subclass basically shows a password dialog before one can edit the preference by the EditTextPreference 's own dialog. Now I define the preference in the corresponding preferences.xml like this: <edu.myproject.pwprefs.PasswordProtectedEditTextPreference android:key="pref_password" android:title="@string/pref_password_title" android:summary="@string/pref_password_summary" android:dialogTitle="

问题 When searching on how to inflate gzip compressed data on iOS, the following method appears in number of results: - (NSData *)gzipInflate { if ([self length] == 0) return self; unsigned full_length = [self length]; unsigned half_length = [self length] / 2; NSMutableData *decompressed = [NSMutableData dataWithLength: full_length + half_length]; BOOL done = NO; int status; z_stream strm; strm.next_in = (Bytef *)[self bytes]; strm.avail_in = [self length]; strm.total_out = 0; strm.zalloc = Z_NULL

问题 I have a very simple question: Is or is it not possible to inflate a view (not add it to layout) in a background thread (ex: in the doInBackground of an AsyncTask )? I know that it is possible, because I have implemented most Activities in my application this way and never had a problem, until I had this problem on a Galaxy S: Android: android.view.InflateException: Binary XML file line #13: Error inflating class <unknown> in SAMSUNG Galaxy S I've been told that I should not inflate Views in

问题 Gzip format files (created with the gzip program, for example) use the "deflate" compression algorithm, which is the same compression algorithm as what zlib uses. However, when using zlib to inflate a gzip compressed file, the library returns a Z_DATA_ERROR . How can I use zlib to decompress a gzip file? 回答1: To decompress a gzip format file with zlib, call inflateInit2 with the windowBits parameter as 16+MAX_WBITS , like this: inflateInit2(&stream, 16+MAX_WBITS); If you don't do this, zlib

问题 Hi I'm working with a view pager and fragments. I would like to override orientation changes so that the onCreateView method isn't run everytime the orientation changes. This is because a lot is run in onCreateView for my app which causes the orientation to be slow to change. Also things on my server are checked and what not too so there really is no reason for all of it to run just because the orientation changed. Here is what i've set up so far I have this on the MainActivity in the

问题 I'm trying to set a click listener for a button in my layout. The click listener is only triggered when I call findViewById() directly, and not when I take the view from the inflated layout: public class MyActivity extends Activity implements View.OnClickListener { private static final String TAG = "MyActivity"; @Override public void onCreate( Bundle savedInstanceState ) { super.onCreate( savedInstanceState ); setContentView( R.layout.test ); Button button = (Button)findViewById( R.id

问题 I am having a strange error that seems to occur only in Samsung Galaxy S with Android 2.2 (I've tested the application in Motorola Milestone 2 Android 2.2 / Xperia X10 Android 1.6 / Nexus One Android 2.2 / Google G1 Android 1.5 and 1.5 emulator and in such devices the error does not occur). The complete stack trace is: ERROR/AndroidRuntime(28111): FATAL EXCEPTION: AsyncTask #2 ERROR/AndroidRuntime(28111): java.lang.RuntimeException: An error occured while executing doInBackground() ERROR

问题 I have a gzip file sample, with standard gzip header 1F 8B 08 00 ... , when I inflate it with inflate* functions in zlib, the output is only 11 bytes(in fact the output should be about 4KB), but when I decompress it with gz* functions, it produce the correct output, the code: using gz* (this can produce correct output): #define CHUNK 10240 int gz_decompress(const char *path) { gzFile f = gzopen(path, "rb"); if(!f) return -1; unsigned char result[CHUNK]; int bytes_read = gzread(f, result,

问题 I have a weird problem. While running my Android application, I receive Exception: java.lang.ClassCastException: android.widget.Button cannot be cast to android.widget.RelativeLayout the code, where I try to get relativeLayout v = inflater.inflate(R.layout.home, null); RelativeLayout btn = (RelativeLayout) v.findViewById(R.id.my_button); in xml, I've got this: <RelativeLayout android:id="@+id/my_button" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background=
