Return current android layout or screen width for debugging

I am trying to add come conditional processing depending on screen width. I set up a refs in my /res/values to point to the appropriate resource on screen width > 600 (sw600dp), have the two layouts, etc. Then I have
Log.d(TAG, "From mButton onClick, layout: " + getActivity().????);
if (getActivity().findViewById(R.id.dialog_widget) == null) {
Intent intent = WidgetActivity.newIntent(getActivity(), mThinger.getInfo());
Log.d(TAG, "From mButton onClick, intent: " + intent.toString());
startActivityForResult(intent, REQUEST_INFO);
} else {
FragmentManager manager = getFragmentManager();
WidgetDialogFragment dialog = WidgetDialogFragment.newInstance(mThinger.getInfo());
dialog.setTargetFragment(ThingerFragment.this, REQUEST_INFO);
dialog.show(manager, DIALOG_INFO);
}
I never hit the else condition, so I am trying to add a Log (see first line of code block) to let me know what layout elements are available, or what the screen width is, or anything to help me know why I'm not seeing the fragment on larger screens. Thanks!

Maybe this will help a bit - at startup of my app I always log:
DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
float dpHeight = displayMetrics.heightPixels / displayMetrics.density;
float dpWidth = displayMetrics.widthPixels / displayMetrics.density;
Log.e(TAG,"dpHeight= "+dpHeight+" dpWidth="+dpWidth);
And one other trick to log the screen layout determined by the system is to use the "values" layout-specific folders:
values-sw320dp/
values-sw420dp/
values-sw600dp/
values-sw720dp/
and in each folder define a strings.xml (or any value resource) which looks like:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="selected_configuration">sw320dp</string>
</resources>
and in App main Applicaton class log:
Log.d(TAG, "Selected configuration: "+getString(R.string.selected_configuration));
You can use another resource value besides string of course.

findViewById with getIdentifier not working

I'm looping through an array, in that for-loop I'm also using this array to get IDs for a couple of spinners:
Integer[] ids;
ids = new Integer[8];
ids[0] = R.id.nr_area;
ids[1] = R.id.nr_municipality;
ids[2] = R.id.nr_method;
ids[3] = R.id.nr_bait;
ids[4] = R.id.nr_sessionhours;
ids[5] = R.id.nr_bifangst_art;
ids[6] = R.id.nr_bifangst_released;
ids[7] = R.id.nr_name;
In the for loop:
for (int i = 0; i < fields.length; i++) {
if(fields[i].contains("*") || fields[i].matches("")){
String test = ids[i].toString();
int resID = getResources().getIdentifier(test, "id", getPackageName());
Spinner spnr = (Spinner) findViewById(resID); //error is on this row
spnr.setBackgroundColor(Color.GREEN);
}
}
Now the error I get is as follows:
android.support.v7.internal.widget.TintEditText cannot be cast to android.widget.Spinner
So I guess this can't be used with a spinner as I found the example code for a EditText.. but how can I do what I'm trying to do with a spinner?
I would appreciate any help! Been fighting with this for hours. Thanks alot..

I think the problem is that either one of the ids is of EditText or id was of EditText and you have changed it to Spinner in your xml lately. Make sure that ids are correct, relate them from xml, if still problem persists, try cleaning your project for indexing again, that should do it.
Hope this helps ...

Adding Multiple Components to LinearLayout Programatically

I am trying to add multiple components into linear layout programatically. Here are the codes:
private View createCalloutView(Graphic graphic) {
LinearLayout ret = new LinearLayout(this);
ret.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
TextView reportContent = new TextView(this);
reportContent.setText(eventName + "\n" + eventBy + "\n" + eventAddress + "\n" + eventDesc
+ "\n" + eventDate + "\n" + eventTime);
reportContent.setTextColor(Color.BLACK);
reportContent.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 12);
reportContent.setPadding(1, 0, 1, 0);
Button viewDtlEventBtn = new Button(this);
viewDtlEventBtn.setText("View details");
viewDtlEventBtn.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT));
ret.addView(reportContent);
ret.addView(viewDtlEventBtn);
return ret;
}
With these codes, I only manged to see the textview and my button is missing. Any ideas? Thanks in advance.

that depends on how do you want to arrange the items in the LinearLayout. If you want to arrange the button next to the TextView, then, probably, the button width should be WRAP_CONTENT instead of FILL_PARENT. If you want to show the button under the TextView, then, your LinearLayout should have vertical as orientation (default is horizontal). Imo, the easiest way is to have your layout defined in a xml file. At least you can see the output at compile time, and use an inflater to retrieve the View's object at run time

The default orientation of linear layout is horizontal. You need to set the orientation first.
LinearLayout ret = new LinearLayout(this);
ret.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
ret.setOrientation(LinearLayout.VERTICAL);
This will solve your problem of missing button.

You have forgot to set Layout Orientation for Linear Layout, just set it as below:
ret.setOrientation(LinearLayout.VERTICAL);

Inflater and loop not working as it should

I am having a problem with a custom view I am currently doing for an app on android, I know there are many questions related with inflaters, but I cannot get around this problem.
the inflater i working just fine, but it should be doing the loop 3 times and is only doing it 1 so I only get one view on my final layout.
the relevant part of the code is this one
void populate(String strcline, String url){
lLfD = (LinearLayout)findViewById(R.id.lLfD);
try{
JSONArray a1 = new JSONArray(strcline);
for(int i = 0; i < a1.length(); i++){
JSONArray a2 = a1.getJSONArray(i);
final String fUserId = a2.getString(0);
String userName = a2.getString(1);
String userPicture = url + a2.getString(2);
View child = getLayoutInflater().inflate(R.layout.cellevery, lLfD);
ImageView avatar = (ImageView)findViewById(R.id.cellAvatar);
downloadFile(userPicture, avatar);
TextView cellName = (TextView)findViewById(R.id.cellName);
cellName.setText(userName);
lLfD.addView(child);
}
}catch(Exception e){
}
pDialog.dismiss();
}

You look like you need to run findViewById only on the inflated view, otherwise it will just find the first one which is only the first one in your loop:
View child = getLayoutInflater().inflate(R.layout.cellevery, lLfD);
ImageView avatar = (ImageView)child.findViewById(R.id.cellAvatar);
downloadFile(userPicture, avatar);
TextView cellName = (TextView)child.findViewById(R.id.cellName);
cellName.setText(userName);
Here's an explanation of findViewById in your loop:
Loop 1:
1LfD->child1->R.id.cellAvatar (findViewById(R.id.cellAvatar) finds this one)
Loop 2:
1Lfd->
child1->R.id.cellAvatar
child2->R.id.cellAvatar (findViewById(R.id.cellAvatar) finds the child1.cellAvatar again)
Loop 3:
1LfD->
child1->R.id.cellAvatar
child2->R.id.cellAvatar
child3->R.id.cellAvatar (findViewById(R.id.cellAvatar) finds the child1.cellAvatar again)
by using child.findViewById(R.id.cellAvatar), it ensures that you find the correct R.id.cellAvatar for each run of the loop.
Does that make sense?
Update 2:
When you call:
getLayoutInflater().inflate(R.layout.cellevery, lLfD);
You are already setting the parent view as the second argument so you don't need to call:
lLfD.addView(child);

getLocationOnScreen crashes

I need to get the coordinates of my app on screen to use them as an offset for a popout.
View tempView = (View) findViewById(R.layout.main);
int[] loc = {0,0};
tempView.getLocationOnScreen(loc); /// crashes here!
Tried this code, but the last line of it makes the app crash. Maybe the tempView I'm getting from the main layout somehow doesn't correspond with the layout on screen?
Any suggestions... thanks! :)
added:
solved
int[] loc = new int[2];
View tempView = (View) findViewById(R.id.LL_whole);
tempView.getLocationOnScreen(loc);
post( String.valueOf(loc[1]) );
works! :)

Try checking to see if tempView is null. I suspect findViewById() is failing to find the id you've given it.
int[] loc = {0,0};
View tempView = (View) findViewById(R.layout.main);
if (tempView != null) {
tempView.getLocationOnScreen(loc);
} else {
Log.d("YourComponent", "tempView was null.");
}
In your XML you have something like this:
<SomeLayout android:id="#+id/myLayout" ... >
<SomeView android:id="#+id/myView" ... />
<SomeOtherView android:id="#+id/myOtherView" .../>
</SomeLayout>
So you want to say:
SomeView v = (SomeView)findViewById(R.id.myView);
Or perhaps:
SomeLayout l = (SomeLayout)findViewById(R.id.myLayout);

findViewById(R.layout.main)
You should place here R.id.something not R.layout.something.
