training and development books

Recently in-house training for companies, mainly on instant messaging and mobile video calls, including Android and Android,ios with Ios,android and iOS, as well as mobile and PCDo not fight unprepared for the war, so carefully collated a more detailed outline, the following outline for mobile video calls,Although the content of the talk is not directly shared, but this outline for everyone to clear the idea of the video call will be helpful,Of course

Be sure to use this unit of measure to indicate the dimensions of the element. For the positioning of th

object.The following example uses the fragment that references LRUCache and passes the issue of configuration changes:PrivateLrucache@Overrideprotected void onCreate(Bundle savedinstancestate) { ... Retainfragment retainfragment = retainfragment.findorcreateretainfragment (Getfragmentmanager ()); Mmemorycache = Retainfragment.mretainedcache;if(Mmemorycache = =NULL) {Mmemorycache =NewLrucache//Initialize cache here as usual} Retainfragment.mretainedcache = Mmemorycache; } ...} Class

(); } }}Note the Getresponsecode () method returns the status code of the connection. This status code can be used to obtain additional information about the connection. A status code of 200 indicates a successful connection.Convert a byte stream to a stringThe inputstream reads the byte data. Once the InputStream object is acquired, it is often necessary to decode it or convert it into other types of data. For example, if you download a picture, the byte stream code should be a picture:nul

" android:layout_height="wrap_content" android:hint="@string/search_hint" android:inputType="text" android:imeOptions="actionSend" />Next, you can listen to the down event of the function button via Textview.oneditoractionlistener and need to respond to the correct IME function ID within the listener, which is defined with the editorinfo, such as the following using Ime_action _send:EditText editText = (EditText) findViewById(R.id.search);editText.setOnEditorActionListener(new OnEdit

Intentservice.Declaring Intentservice in the manifest fileThe intentservice also needs to be defined in the manifest file. It is defined in the same way as the normal service.application android:icon= "@drawable/icon" android:label="@st Ring/app_name ">...- service android:name=".

Note that the navigation bar (to the right of the image) is a light white dot here:The same image is displayed, but the system bar is completely displayed:Lighten the status navigation barIf you want to clear this flag, you can do this:View decorView = getActivity().getWindow().getDecorView();// Calling setSystemUiVisibility() with a value of 0 clears// all flags.decorView.se

It has been several months since I arrived at the Software Park. Some of the previous. Net-related things have been slowly lost. I am always concerned about related things. Some of the items subscribed in the past are still very useful. I collected some relevant information and learned some related training information. It is gratifying that many of the training courses are on the Software Park side. If you
