After searching for a solution, I found this: Android - Camera preview is sideways where the

Standard intent URI broken?

由 a 夏天 提交于 2019-12-22 05:39:06
问题 I'm having problems with intent URIs on a particular device, so I tried the CommonsWare URLHandler sample as suggested here: Launching my app using the intent URI, and the intent URI hyperlink on its sample page also fails to invoke the application. The sample declares its intent-filter like this: <intent-filter> <action android:name="com.commonsware.android.MY_ACTION" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.BROWSABLE" />

Why do recipes promote overriding getItemViewType and getViewTypeCount when it doesn't seem necessary?

问题 I've been working through the Commonsware Android Programming Tutorials and in tutorial 5, extra credit 2, the challenge is to use multiple layouts for displaying rows in a ListView depending on the "type name" of the object (a Restaurant's "type" attribute, which is a String). As such, it suggests overriding getItemViewType and getViewTypeCount in a custom ArrayAdapter. In addition, the android docs and other online recipes or blog posts suggest the same. In this situation, following this

问题 I'm working with Mark Murphy's excellent Commonsware books - but it's a lot to digest. I built the 'FakePlayer' app (pretends to be an mp3 player). It contains a service. As a learning experience I tried to write a trivial app (has only a button) whose click handler does: Intent i = new Intent(); i.setAction("com.example.cwfakeplayer.MyPlayerService"); Context context = getApplicationContext(); context.startService(i); It worked fine - the service start ok. I noticed Eclipse complaining about

What's the difference between passing this vs. ClassName.this from an event handler when passed to Intent constructor?

问题 In the earlier Android Programming Tutorial, page 192, we see an implementation of LunchList#onOptionsItemSelected . Within this implementation we see two Intent s passed to startActivity : one whose constructor is passed LunchList.this , the other whose constructor is passed this . What's the difference? See lines 78 - 91 here. Note how onOptionsItemSelected is not declared within an inner class. In Android/Java does the value of this change within the context of event handlers or function

Can't find the leak, on my fragment android code

由 青春壹個敷衍的年華 提交于 2019-12-11 12:14:18
问题 I have a TabLayout, under each tab there is a Fragment (I'm using ArrayPagerAdapter). I've noticed that when I switch many times from a tab to another, my memory usage increase a lot. From my heap snapshot, I can see there are a lot of AutoCompleteTextView instances. So I am convinced that the problem could be here: public class MyFragment { ... @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { ... final MultiAutoCompleteTextView

XML attributes from merge layout to RelativeLayout via inflate

由 寵の児 提交于 2019-12-08 16:01:19
问题 According to this CommonsWare example I managed to get my RelativeLayout subclass to be merged with my layout described in a xml layout with merge root. My only concern is that I cannot describe my RelativeLayout parameters in xml. My xml layout: <?xml version="1.0" encoding="utf-8"?> <merge xmlns:android="http://schemas.android.com/apk/res/android" xmlns:my="http://schemas.android.com/apk/res/hu.someproject" android:layout_width="36dp" android:layout_height="wrap_content" android:layout
