  • Zoom controls not showing when using a MapView with fill_parent

    - by Joe
    Hey everyone I am working on an applications and I am using the built in zoom controls. When using a specific size I can see the zoom controls. When using fill_parent the zoom controls are not visible. How it is setup is a mapview inside of a frame layout(also using fill parent for the height and width but with an offset down the screen. The only thing I can think of is the fill parent issue is with the framelayout and the zoom controls are off the screen. Sorry if this is confusing, I confused myself writing it. Thanks in advance

  • Singleton wrapper for Context

    - by kpdvx
    I'm considering creating a singleton wrapper for a Context so my model objects, if necessary, can open and read from a database connection. My model objects do not have access to a Context, and I'd like to avoid needing to pass a reference to a Context from object to object. I was planning to place into this singleton a reference to the Context returned by Application.getApplicationContext(). This singleton object would be initialized in my custom Application instance before anything else would need to or have a chance to use it. Can anyone think of a reason to not do this?

  • How do you access country/state/province polygons in google maps api?

    - by wmh1108
    I have fairly large map overlay that I am displaying over the google maps data but would still like to see the country/state/province lines through my overlay (so the lines would essentially be on top of my overlay). As I understand, these lines are simply polygons drawn over the maps. Is there any way to access these? If so, how do I get them to show up through my overlay images?

  • Why are button sizes on Eclipse vs Device not the same.

    - by Mike Droid
    O.k....this is weird. I had my buttons looking fine last week, now something has changed. My buttons on the eclipse emulator are much larger than on my device (Droid 2.1). I checked my skin settings, screen size permissions, density factors....what am I missing? My skin is set to WVGA854, but when the app goes to the phone the buttons are smaller!? Text and pictures are fine...looking the same as the emulator...just the buttons are shrunk! Hmm....I know it has to be something simple...:)

  • Can't return data to parent activity

    - by user23
    I'm trying to return data (the position of the item picked from the grid) to parent activity, but my code fails. The debbuger shows how 'data' gets right the key and data in the "data.putExtra("POS_ICON", position)" at child activity, but after in onActivityResult() at parent activity the debbuger shows 'data' with no key nor data returned...it's like if data loses its content. I've followed other posts and tutorials but no way. Please help. Parent activity: public void selIcono(View v){ Intent intent = new Intent (this, SelIconoActivity.class); startActivityForResult(intent,PICK_ICON_REQUEST); } protected void onActivityResult(int requestCode, int resultCode, Intent data) { //here's the problem: no data is returned!! if (requestCode == PICK_ICON_REQUEST) { if (resultCode == RESULT_OK) { // An icon was picked. putIcon(data.getIntExtra("POS_ICON", -1)); } } } Child activity: public class SelIconoActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_sel_icono); GridView gridview = (GridView)findViewById(R.id.gr_iconos); gridview.setAdapter(new ImageAdapter (this)); gridview.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView<?> parent, View v, int position, long id) { Intent data = new Intent(); data.putExtra("POS_ICON", position); setResult(Activity.RESULT_OK, data); finish(); } }); } }

  • Key Events in TabActivities?

    - by stormin986
    I have a TabActivity and want to catch and handle presses of HOME and BACK. Where do I need to catch these events? In my subclass of TabActivity I implement the following: @Override public boolean onKeyDown(int keyCode, KeyEvent event) { switch (keyCode) { // Code handling } return super.onKeyDown(keyCode, event); } Didn't work. So I placed a breakpoint on the switch statement line. But this function never gets called, whether I press volume up/down, menu, home, or back. Where do I need to catch these KeyEvents?

  • Handle edittexts onKeyListener ?

    - by hungson175
    Hi everyone, I am creating login screen with 2 editTexts: etUsername and etPassword. On the etUsername, user should input the username and press Enter to go to the edit text etPassword, then he inputs the password, press Enter to login. Here are my current codes: etUsername.setOnKeyListener(new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_ENTER)) { etPassword.requestFocus(); return true; } else return false; } }); etPassword.setOnKeyListener(new OnKeyListener() { @Override public boolean onKey(View v, int keyCode, KeyEvent event) { if ((keyCode == KeyEvent.KEYCODE_ENTER)) { loginToServer(); return true; } else return false; } }); But when I input the username, and then press Enter – the program tries to log in to the server. In the debug mode, I saw that when I pressed Enter once (on the etUsername) then first: etUsername.onKey() is called and then etPassword.onKey() is also called ! Can anyone please tell me, how to implement what I want ? Thank you very much, Son

  • 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; } }
