Android multiple lists using #id/android:list - java

I've got a new List of things that needs to be clicked but this one isn't working. onListItemClick is never called. I have another one in my app that has been working as expected and I can't figure out what the difference is. It occurs to me that maybe there's some conflict since they are both using the provided #id/android:list but they're in different Activities and I haven't found other people complaining about the same problem so I'm not sure.
Here is a bunch of code. I would appreciate any suggestions.
Working:
#Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
// get the item that was clicked
v_ProjectInvestigatorSiteContact project = (v_ProjectInvestigatorSiteContact) this.getListAdapter().getItem(
position);
Intent myIntent = new Intent(this, Details.class);
myIntent.putExtra(res.getString(R.string.project), project);
startActivity(myIntent);
}// onListItemClick
Not Working:
#Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
super.onListItemClick(l, v, position, id);
// get the item that was clicked
final v_SitePeople vSitePeople = (v_SitePeople) this.getListAdapter().getItem(
position);
AlertDialog.Builder builder = new AlertDialog.Builder(Share.this);
builder.setTitle(res.getString(R.string.forgot_password_check_dialog_title))
.setMessage(res.getString(R.string.share_check_dialog_text))
.setPositiveButton(res.getString(R.string.send), new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which)
{
sendShareEmail(vSitePeople);
}
}).setNegativeButton(res.getString(R.string.cancel), new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which)
{
// cancelled, so do nothing
}
});
AlertDialog msgBox = builder.create();
msgBox.show();
}// onListItemClick

I figured it out. I didn't ever post the relevant code, or I'm sure you guys would have spotted it for me.
I copied a non working adapter from a working piece of code which returns false if the viewType is 0. And since my second list only has one type, everything was disabled.
Thank you all for your efforts. I apologize that I didn't give you the correct code.

I have a custom dialog that has a ViewPager inside of it, when the dialog shows the ViewPager is just blank, not progressing on swipe or when pressing the "Next" button I implemented. I tried slightly altering my code and it didn't work. I saw several posts like this, but none of their solutions worked. PS if some things don't make sense or have mismatched names then that's because I renamed/removed some of the files/variables to simplify.

The problem is that you didn't set the ViewPager adapter
public class DialogWeeklyReport extends AppCompatDialogFragment {
...
#NonNull
#Override
public Dialog onCreateDialog(#Nullable Bundle savedInstanceState) {
...
viewPager = view.findViewById(R.id.viewPager);
...
adapter = new SliderAdapter(getActivity(), text);
viewPager.setAdapter(adapter); // <<<<<< change here
return builder.create();
}
...
Here is my test

I have progress listview of progress items. Whenever the item is finished I checkmark it.
This Progress items are divided into Phases. Each phase can contain Steps. After all steps are done and marked with checkmark, code marks whole phase as done.
At the end what I do is just render a listview of phases and for each phase I dynamicly add another listview in it. I end up with listview with more listviews in it.
This works fine and I don't have any problems with it.
My boss asked me to create auto scroller which would follow the steps as being completed. This I implemented and was happy to see that It works.
Problem: I was happy that It works only to the point when the something little over of half is reached. Then suddenly items disapear. When I touch the list, List goes back to top and all the items are visible.
Any idea what could couse this behavior?
The code for this is quite large so I will share only the parts I think are needed.

Your adapter code does not work in my phone. Only part of the child list is shown. In addition, I think your requirements are easier to implement by ExpandableListView. Therefore I followed your data structure and created the following demo codes which use ExpandableListView. You can start a new project and try it.
MainActivity.java:
public class MainActivity extends AppCompatActivity {
ProgressOverviewData sampleData;
ProcessFeedbackAdapter1 adapter;
ExpandableListView listView;
TextView textView;
int completedPhase = 0;
#Override
protected void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
sampleData = new ProgressOverviewData("Project", new ArrayList<Phase>());
textView = findViewById(R.id.ProgressMessage);
textView.setText(sampleData.projectName);
listView = findViewById(R.id.ProgressStepsContainer);
adapter = new ProcessFeedbackAdapter1(this, sampleData);
listView.setAdapter(adapter);
// Disable ExpandableListView from group collapse by override OnGroupClickListener.
listView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
#Override
public boolean onGroupClick(ExpandableListView expandableListView, View view, int i, long l) {
return true;
}
});
for (int i = 0; i < sampleData.Phases.size(); i++) listView.expandGroup(i);
Button btAddPhase = findViewById(R.id.bt_add_phase);
btAddPhase.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Phase newPhase = genNewPhase();
sampleData.Phases.add(newPhase);
adapter.notifyDataSetChanged();
listView.expandGroup(sampleData.Phases.size() - 1);
textView.setText(sampleData.projectName + " [" + completedPhase + "/" + sampleData.Phases.size() + "]");
}
});
Button btCompletedStep = findViewById(R.id.bt_completed_step);
btCompletedStep.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
boolean stepCompleted = false;
Step step;
String msg = "";
int viewPosition = 0;
for (int i = 0; i < adapter.getGroupCount(); i++) {
viewPosition++;
for (int j = 0; j < adapter.getChildrenCount(i); j++) {
viewPosition++;
if (adapter.getChild(i, j).Status == AppEnums.StepResult.NotCompleted) {
step = adapter.getChild(i, j);
step.Status = AppEnums.StepResult.Completed;
msg = step.StepName + " Completed!";
if (j == adapter.getGroup(i).PhaseSteps.size() - 1) {
adapter.getGroup(i).Status = AppEnums.StepResult.Completed;
completedPhase++;
textView.setText(sampleData.projectName + " [" + completedPhase + "/" + sampleData.Phases.size() + "]");
msg += "\n" + adapter.getGroup(i).PhaseName + " Completed!!!!!";
}
stepCompleted = true;
break;
}
}
if (stepCompleted) break;
}
if (stepCompleted) {
Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getApplicationContext(), "All Completed", Toast.LENGTH_LONG).show();
}
listView.smoothScrollToPositionFromTop(viewPosition - 1, 0);
adapter.notifyDataSetChanged();
}
});
}
private Phase genNewPhase() {
int phaseId = sampleData.Phases.size() + 1;
Random random = new Random();
int numberOfSteps = random.nextInt(5) + 1;
ArrayList<Step> steps = new ArrayList<>();
for (int j = 0; j < numberOfSteps; j++) {
Step step = new Step("Step " + (phaseId) + "-" + (j + 1));
steps.add(step);
}
return new Phase("Phase " + (phaseId) + " [" + steps.size() + "]", steps);
}
}

add ProgessBar progressBar; as global variable in your activity

So far everything is working great as expected.
But I would like to add an header to the table.
Something like:
# | Name | Pts
I tried to add this in the layout, and check if the position != 0 and set the visibility to GONE, but the problem is when I scroll down and up it disappears.
My question is: How can I add and header to this table?
Or add this header fixed, and everything else scrollable?

In your adapter, add these two method overrides:
#Override
public int getViewTypeCount() {
return 2;
}
#Override
public int getItemViewType(int position) {
return position == 0 ? 0 : 1;
}
This tells the adapter that you have two types of row layout, and which rows have each type.

I've spent half day reading documentation and examples. I can't find a solution.
I've a ListView in an Activity, each item has LinearLayout with a background image loaded with Android-Universal-Image-Loader by nostr13.
I use this library to put a LinearBackground image as a background. In my Activity I download a JSON, parsing and creating a String array with the URIs.
The problem is the print done by the library is wrong! It works fine with ImageView but if I use LinearBackground with loadImage() intestead of displayImage() it doesn't put correctly the backgrounds. The procees seen at slow motion is like: create the right number of elements (4), place the first loaded image as background of one row, then once another image is loaded the library replaces the old background with this new image, different, then it places another image and stop. This is an example of the bug. It's always different!!! Some of them are empty but the onLoadingComplete event is called. I thought it was a problem of cache and I've played with the UIL's options without luck. Images are just 4 and very small (<10kb each).
I set the adapter in the onPostExecute event, is it ok?
What can be the problem?
Here the important code:
The Activity code (i've removed not relevant code to help to find the problem):
public class myActivity extends Activity {
Context context;
// Output Vars
String mStrings[];
ListView listView;
// UIL
DisplayImageOptions options;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.overridePendingTransition(R.anim.anim_slide_in_left, R.anim.anim_slide_out_left);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_stagioni);
listView = (ListView) findViewById(R.id.listView);
options = new DisplayImageOptions.Builder()
.showImageOnLoading(R.drawable.ic_launcher)
.showImageForEmptyUri(R.drawable.fail)
.showImageOnFail(R.drawable.fail)
.cacheInMemory(true)
.cacheOnDisc(true)
.considerExifParams(true)
.build();
startAsynkTask(context);
}
public void startAsynkTask(final Context context) {
AsyncTask<String, Void, Void> task = new AsyncTask<String, Void, Void>() {
private ProgressDialog pd;
#Override
protected void onPreExecute() {
pd = new ProgressDialog(ActivityStagioni.this);
pd.setTitle(getResources().getString(R.string.dialog_loading));
pd.setMessage(getResources().getString(R.string.dialog_loading_stagioni));
pd.setCancelable(true);
pd.setCanceledOnTouchOutside(true);
pd.setIndeterminate(true);
pd.show();
}
#Override
protected Void doInBackground(String... arg0) {
//... Not relevant code ...
}
#Override
protected void onPostExecute(Void result) {
pd.dismiss();
((ListView) listView).setAdapter(new ImageAdapter());
listView.setOnItemClickListener(new OnItemClickListener()
{
//... Not relevant code ...
});
}
};
task.execute();
}
public class ImageAdapter extends BaseAdapter {
ImageLoader imageLoader;
public ImageAdapter() {
imageLoader = ImageLoader.getInstance();
}
#Override
public int getCount() {
return mStrings.length;
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
//ImageLoadingListener animateFirstListener = new AnimateFirstDisplayListener();
final ViewHolder holder;
View view = convertView;
if (view == null) {
view = getLayoutInflater().inflate(R.layout.stagioni_item, parent, false);
holder = new ViewHolder();
assert view != null;
holder.imageView = (LinearLayout) view.findViewById(R.id.linearLayoutLocandina);
holder.progressBar = (ProgressBar) view.findViewById(R.id.progress);
view.setTag(holder);
} else {
holder = (ViewHolder) view.getTag();
}
imageLoader.loadImage(mStrings[position], new SimpleImageLoadingListener() {
//final List<String> displayedImages = Collections.synchronizedList(new LinkedList<String>());
#Override
public void onLoadingComplete(String imageUri, View view, Bitmap loadedImage) {
// Do whatever you want with Bitmap
//if (loadedImage != null) {
// boolean firstDisplay = !displayedImages.contains(imageUri);
// if (firstDisplay) {
BitmapDrawable background = new BitmapDrawable(loadedImage);
holder.imageView.setBackgroundDrawable(background);
//}
// }
}
});
return view;
}

Thanks for support

Add this ImageAware into your project:
public class BgImageAware implements ImageAware {
public static final String WARN_CANT_SET_DRAWABLE = "Can't set a drawable into view. You should call ImageLoader on UI thread for it.";
public static final String WARN_CANT_SET_BITMAP = "Can't set a bitmap into view. You should call ImageLoader on UI thread for it.";
protected Reference<View> viewRef;
protected boolean checkActualViewSize;
public BgImageAware(View view) {
this(view, true);
}
public BgImageAware(View view, boolean checkActualViewSize) {
this.viewRef = new WeakReference<View>(view);
this.checkActualViewSize = checkActualViewSize;
}
#Override
public int getWidth() {
View view = viewRef.get();
if (view != null) {
final ViewGroup.LayoutParams params = view.getLayoutParams();
int width = 0;
if (checkActualViewSize && params != null && params.width != ViewGroup.LayoutParams.WRAP_CONTENT) {
width = view.getWidth(); // Get actual image width
}
if (width <= 0 && params != null) width = params.width; // Get layout width parameter
return width;
}
return 0;
}
#Override
public int getHeight() {
View view = viewRef.get();
if (view != null) {
final ViewGroup.LayoutParams params = view.getLayoutParams();
int height = 0;
if (checkActualViewSize && params != null && params.height != ViewGroup.LayoutParams.WRAP_CONTENT) {
height = view.getHeight(); // Get actual image height
}
if (height <= 0 && params != null) height = params.height; // Get layout height parameter
return height;
}
return 0;
}
#Override
public ViewScaleType getScaleType() {
return ViewScaleType.CROP;
}
#Override
public View getWrappedView() {
return viewRef.get();
}
#Override
public boolean isCollected() {
return viewRef.get() == null;
}
#Override
public int getId() {
View view = viewRef.get();
return view == null ? super.hashCode() : view.hashCode();
}
#Override
public boolean setImageDrawable(Drawable drawable) {
if (Looper.myLooper() == Looper.getMainLooper()) {
View view = viewRef.get();
if (view != null) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
view.setBackground(drawable);
} else {
view.setBackgroundDrawable(drawable);
}
return true;
}
} else {
L.w(WARN_CANT_SET_DRAWABLE);
}
return false;
}
#Override
public boolean setImageBitmap(Bitmap bitmap) {
if (Looper.myLooper() == Looper.getMainLooper()) {
View view = viewRef.get();
if (view != null) {
Drawable drawable = bitmap == null ? null : new BitmapDrawable(view.getResources(), bitmap);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
view.setBackground(drawable);
} else {
view.setBackgroundDrawable(drawable);
}
return true;
}
} else {
L.w(WARN_CANT_SET_BITMAP);
}
return false;
}
}
And then wrap your LinearLayout into it and pass to displayImage(...) method:
ImageAware imageAware = new BgImageAware(holder.imageView);
imageLoader.displayImage(mStrings[position], imageAware);
