  • best way to make this app/website combo?

    - by mharris7190
    I have an idea for an app that lets different bars upload drink specials via a webpage to that app. They would log in the website, and the website would prompt them with a box to input the drink specials. When they are done, the app pulls the information and creates a card for that bar. The app would launch into a week view where you select the day you want to see specials for. After the day is selected, it brings you to a scroll view with different bars' cards laid out vertically, each taking up the width of the screen, allowing the user to scroll through the deals for that day of the week. How should I go about doing this if I have very little programming experience? Is there any convention in doing an app like this? Can anyone suggest any reading material that would help? Thank you!

  • Call OnDraw in another method, then "refresh" that call in ANOTHER method.

    - by Aidan
    Hey guys, Hopefully this will actually make sense and sorry if its a stupid / obvious question. Basically I'm calling the onDraw method like so... requestWindowFeature(Window.FEATURE_NO_TITLE); Preview mPreview = new Preview(this); DrawOnTop mDraw = new DrawOnTop(this); setContentView(mPreview); addContentView(mDraw, new LayoutParams (LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); You see I'm drawing it on top of a Camera view and the information being drawn is subject to change. I have a listener setup which will update the variables being drawn at the appropriate time but I now want to "refresh" this draw in that listener. How would I do such a thing?

  • How can specific the layout_width and layout_height of a Framelayout which fits an image

    - by michael
    Hi, I have an image which is 80px X 50 px, and I need to place that in one of the child of a FrameLayout, how can I specific the layout_width and layout_height of a Framelayout which fits an image without scaling it? I know there is a layout_height="wrap_content" layout_wight="wrap_content" for FrameLayout, but I can't use it, since that FrameLayout has other children. So I would like to hard code the FrameLayout width/height to match the dimension of the image? Should I use layout_width="80px" or layout_width="80dip"? Thank you.

  • How to emulate onLowMemory()?

    - by Samuh
    I have put some instructions in onLowMemory() callback and want to test the same. Is there a "direct" way to test onLowMemory function of the application subclass? Or will I have to just overload the phone by starting many apps and doing memory intensive tasks? Thanks.

  • using both layout-land and onConfigurationChanged()

    - by joe
    I just want to change Layout when the device has been rotated. but I've found that onConfigurationChanged() must call onCreate() again using setContentView with separated layout named of *_land.xml if(getActivity().getWindowManager().getDefaultDisplay(). getRotation() == Surface.ROTATION_0) view = inflater.inflate(R.layout.fragment_layout, null); else view = inflater.inflate(R.layout.fragment_layout_land, null); Project is too big and there are many codes to fix If onCreate again without finish(). I'd like somebody help this. Thank you. - onConfigurationChanged concept is keep layout I think

  • retrieving and restoring textview information from sharedpreferences

    - by user1742524
    I have an activity that allows user to enter notes and store them in dynamically created textviews. However, when the use leaves the activity and returns, all the created textviews disappear. How can i store store or retrieve all of these created textviews, whenever i return to the activity? Also, i think that my sharedpreferences will be overwriting each time a new textview is added. Any suggestions? public class DocNoteActivity extends Activity { private LinearLayout nLayout; private EditText etDocNote; private Button btnAdd1; public static final String PREFS_NAME = "MyPrefsFile"; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.adddocnote); etDocNote = (EditText) findViewById(R.id.editDocNote); btnAdd1 = (Button) findViewById(R.id.btnAdd1); nLayout = (LinearLayout) findViewById(R.id.linearLayout); TextView tvNote = new TextView(this); tvNote.setText(""); btnAdd1.setOnClickListener(onClick()); } private OnClickListener onClick() { // TODO Auto-generated method stub return new OnClickListener(){ public void onClick(View v) { // TODO Auto-generated method stub String newDocNote = etDocNote.getText().toString(); nLayout.addView(createNewTextView(newDocNote)); getSharedPreferences("myprefs", 0).edit().putString("etDocNote", newDocNote).commit(); } }; } private TextView createNewTextView(String newText) { // TODO Auto-generated method stub LayoutParams lparams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); TextView tvNote = new TextView(this); tvNote.setLayoutParams(lparams); tvNote.setText(newText); return tvNote; } }

  • A Map of View instances?

    - by user291701
    Is it possible to keep references to views keyed off of their hashCode? Something like: Map<Integer, View> views; views.put(view1.hashCode(), view1); views.put(view2.hashCode(), view2); views.put(viewN.hashCode(), viewN); I have a few in my view hierarchy and am downloading images for each. I want to be able to iterate over them quickly, or see if I've already previously added one (hence the map).

  • Monitoring of Activities visibility

    - by vochupin
    Is it possible to determine the moment of switching of certain Activity from foreground to background and vice versa? This activity should run in the separate process. I need to write the application that collects some statistics from using of big set of applications (app names read from configuration file). My application works as Service and should remember moments of switching of activities between foreground and background. Set of applications is sufficiently big and most part of these applications will never work on certain phone.
