Android. Access to NavigationDrawer from fragment

G
gionna last edited by

Used by NavigationDraver, there is a problem when you start a piece of his menu, the relevant menu is distinguished, but sometimes it is necessary to go to the section not through the menu but by the event, and then when the menu is opened, the previous paragraph will be added. Since it's written in Activity, I can't directly influence his development. Please indicate how to get access from a fragment to the NavigationDrawer. You can make it static, but it's a pepper colt.

We can differently:
1. The fragment has a method. getActivity()the result of which you can cast into your activate class and call her method.
2. Libraries can be used to correct/take user events. In the activate, sign for their receipt, and in the recipient's method, do something with the diver. Send it out of the fragment. Library https://github.com/greenrobot/EventBus and http://square.github.io/otto/

You can use the following DDL:ALTER TABLE tabela ADD COLUMN nova_coluna CHAR(50) https://stackoverflow.com/questions/4253804/insert-new-column-into-table-in-sqlite Add this code to the method onCreate(), right after your CREATE TABLE. Also, add to your creation query the condition to create only if there is no, for example:CREATE TALBE IF NOT EXISTS table ...restante da query Thus, when a new version of the bank (or the first installation of the app) is installed the table will be created only if it does not exist, preserving the already installed data (when the app is updated), and the ALTER TABLE will change the structure of your table.These commands will only run the first time the new version of the bank is installed (or the first installation of the app).I tested here and it worked.

I have now checked your question that you have declared FloatingActionButton in your Fragment. This way you cannot use the findViewById() directly from your MainActivity, and that's why he's getting null.Take a good look http://developer.android.com/intl/pt-br/reference/android/app/Activity.html#findViewById(int) :Finds a view that was identified by the id attribute from the XML that was processed in onCreate(Bundle).That is, using findViewById() direct from your MainActivity, the function will look for this FloatingActionButton inside layout that is connected to your MainActivity and not yours Fragment.To solve the problem just you instanciate this FloatingActionButton inside your Fragment and set your click event inside, or you move this FloatingActionButton for your layout MainActivity.

To update the fragment, for example:Fragment frg = null; frg = getSupportFragmentManager().findFragmentByTag("Your_Fragment_TAG"); final FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); ft.detach(frg); ft.attach(frg); ft.commit(); https://stackoverflow.com/questions/20702333/refresh-fragment-at-reload There's a question like that. If you need to pass some data, you can use it. http://developer.alexanderklimov.ru/android/fragment5.php ♪

String[] allowedContentTypes = new String[] { "image/jpeg" }; JPEG files are.When I saw an error message, it seems that the content type downloaded was not downloadable because it is "text/html".You can also use text/html to see the contents of the downloaded HTML.Do you have asynchronous communication?If so, try to open finish downloading.This may be more than the limits of the opening of Android SDK-specific or hardware-specific concurrent programs.The most common web browser has 6 requests that can be downloaded at the same time.

API device/emulator what? onAttach(Context context) only works for API23+, i.e. starting with Android 6. Or use it. onAttach(Activity activity) use android support.v4.app.Fragment from the support library.

Just a hint about Java and android, there's no way to put apps inside ./assets and perform them, what you do is use one Intent to access another application installed on Android or else you put a library (.java or .jar) in your project that gives the ability of your application to read PDFs.To view the PDF with the standard reader of the device you can use the code quoted in this https://stackoverflow.com/a/10530506/1518921 :File file = new File("CAMINHO DO SEU PDF/example.pdf"); Intent intent = new Intent(Intent.ACTION_VIEW); intent.setDataAndType(Uri.fromFile(file), "application/pdf"); intent.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY); startActivity(intent); If there may be the possibility of not having an app for reading, you may have wanted to use a library as https://github.com/ieee8023/PDFViewer , in this case you will also have to use one Intent, this well updated but lacks documentation.Alternatively you can see this repository https://github.com/JoanZapata/android-pdfview , to use it do something like:pdfView.fromAsset("CAMINHO DO SEU PDF/example.pdf") .pages(0, 2, 1, 3, 3, 3) .defaultPage(1) .showMinimap(false) .enableSwipe(true) .onDraw(onDrawListener) .onLoad(onLoadCompleteListener) .onPageChange(onPageChangeListener) .load();

The approach is not the only correct one, and the fragmentation of the base is increasing. In your task, the best thing to do is set up a "semi" in a database that will be marked by displaced persons in the basket, with full removal, the recording is removed, the reinstatement takes off a note of the presence in the basket.

Use this method:public static Bitmap getBitmapFromView(View view, int totalHeight, int totalWidth) { Bitmap returnedBitmap = Bitmap.createBitmap(totalWidth,totalHeight , Bitmap.Config.ARGB_8888); Canvas canvas = new Canvas(returnedBitmap); Drawable bgDrawable = view.getBackground(); if (bgDrawable != null) bgDrawable.draw(canvas); else canvas.drawColor(Color.WHITE); view.measure( View.MeasureSpec.makeMeasureSpec(totalWidth,View.MeasureSpec.EXACTLY), View.MeasureSpec.makeMeasureSpec(totalHeight,View.MeasureSpec.EXACTLY)); view.layout(0,0,totalWidth,totalHeight); view.draw(canvas); return returnedBitmap; }

You are not booting the variable mContext.Do it Override of the method onAttach() the Fragment and start it there:@Override public void onAttach(Activity activity) { super.onAttach(activity); mContext = activity; }

To return you can simply call the most onBackPressed() of the Activity containing the Fragment:getActivity().onBackPressed(); this is done to close the Activity and return to an anonymity.Update:The user wishes to change Fragment de PostDetailFragment a HomeFragment, then what is done in this case is a Fragment Transacciòn:getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container, new HomeFragment()).commit();

What you want is from Fragment Call ClothesFragment go to the Activity AddClothesActivity, in this case you can load an Activity using an Intent using as context the activity that contains the Fragmente by getActivity():Intent intent = new Intent(getActivity(), AddClothesActivity.class); startActivity(intent);

In some situations, yes.The PRIMARY KEY of a rowid table (if there is one) is usually not the true primary key for the table, in the sense that it is not the unique key used by the underlying B-tree storage engine. The exception to this rule is when the rowid table declares an INTEGER PRIMARY KEY. In the exception, the INTEGER PRIMARY KEY becomes an alias for the rowid. https://www.sqlite.org/rowidtable.html .The PRIMARY key of a rowid table (if there is one) is usually not the true primary key to the table, insofar as it is not the unique key used by the underlying B-tree storage mechanism. The exception to this rule is when the rowid table declares an INTEGER PRIMARY KEY. In the exception, INTEGER PRIMARY KEY becomes an alias for the rowid.So your modeling can make it true or not. What is recommended to do so most of the time. https://sqlite.org/autoinc.html .

You can do this by using the method https://developer.android.com/reference/android/os/AsyncTask.html#get() to obtain the value obtained in onPostExecute(): String resultadoAsynctask = new MyAsyncTask().execute().get(); You must take into account that the process would wait until you get the AsyncTask result, this by using https://developer.android.com/reference/android/os/AsyncTask.html#get() : https://developer.android.com/reference/android/os/AsyncTask.html#get() Wait if necessary to complete the calculation, And then he recovers his result.In your code it would be: try { String type = "spinnerq"; String resultadoAsynctask = new MyTask().execute(type).get(); } catch (InterruptedException e) { e.printStackTrace(); } catch (ExecutionException e) { e.printStackTrace(); }

I'd take cues from Facebook on this. They keep their call to action for share separated from their report options. In Facebook clicking the icon style your friend has come up with present various reporting options such as hide post, report abuse etc. Share should be a dedicated action if it's an action you want to encourage and know the user will benefit from. My suggestion is to keep your share icon (bare in mind that iOS 7 has a standardised share sheet icon) but offer a much less prominent report button either as text or a similar icon to your friends idea. The two actions are not related and should be detached from one another.

When you start the service the first method to be called is onCreate() and later onStartCommand():public class myService extends Service { @Override public void onCreate() { super.onCreate(); ... ... } public int onStartCommand(Intent intent, int flags, int startId) { ... ... } } From the documentation: https://developer.android.com/guide/components/services.html The system calls this method when creating the service for the first time, to perform the procedures configuration for one time (before calling onStartCommand() or onBind()). If the service is already running, it is not called this method.As to your question:Is there a chance that the service will be late? I mean, the "start service" waits for the service to pass through the oncreate?The first time you start the service necessarily has to call onCreate() that takes the role of initializing/configure the service, if it takes time to start your service you probably have some process at this point that causes the problem.
