How to if conditions between two intents in Android Studio?

Рow to use if statements between two intent activities? I have two different activities collecting data from external sensors. I would like to control some GPIO pins of Activity1 based on the sensor values of Activity2.
Activity 1

In the above codes the GPIO pins must be controlled by the co2ppm1 sensor values (If the co2ppm1 sensor value is above 2000, it must turn ON GPIO 9 pin).

onTextChangedListener goes into loop, but only on first ListView element, any following elements don't loop

I have a moneyConversion class which converts strings as I type them into an EditText which there are multiple of due to being contained in a listview. The conversion works fine for the EditText, but for some reason, the first list item always goes into a loop and hangs when typing something in, where as all other identical EditText boxes work absolutely fine and format without issue.
Here's my adapter.

Write your textchangeListener inside if (ListItem == null) { condition block, it will work.
What actually happening in your case is whenever you scroll your listview on change listener will call for each and every row that is visible.

This is the above code please go through it and let me know if any clarifications are required. I cannot able to set "itemsTotal" value to "noOfIttems" textview. I have added the comments. Please help me in solving this issue.
Thanks in advance.

Please check your noOfItems textView's id. TextView is null.

Sharing Intent Not working Properly

I have one quote application. I have implemented share and copy function in it. I am facing issue is that I am not getting shared first time sharing quote. Means if there 50 quote in list and if I try to share any quote from list than it is not sharing anything. after that if I move on another quote and try to sharing than its working fine. I have same issue in copy function also. I also face some time issue like if I share quote number 50 than its sharing another number quote. Please help me for solve the bug. Thanks

Multiselect Spinner with hints

hey i want add hint to MultiSelector from https://github.com/wongk/MultiSelectSpinner
i mixed it with https://github.com/ravivyas84/AndroidSpinnerHint
its look like this i add own SpinnerAdapterProxy that extends ArrayAdapter<String>
public MultiSelectSpinner(Context context) {
super(context);
_proxyAdapter = new SpinnerAdapterProxy(context, android.R.layout.simple_spinner_item);
super.setAdapter(_proxyAdapter);
_context = context;
}
(...)
public void setHint(String hint) {
_proxyAdapter.setHint(hint);
}
adapter
public class SpinnerAdapterProxy extends ArrayAdapter<String> {
private LayoutInflater mInflator;
private TextView text;
private boolean selected = false;
private String hint;
public SpinnerAdapterProxy(Context context, int resource) {
super(context, resource);
// TODO Auto-generated constructor stub
mInflator = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = mInflator.inflate(android.R.layout.simple_spinner_item, null);
}
text = (TextView) convertView.findViewById(android.R.id.text1);
if (!selected) {
text.setHint(hint);
} else {
text.setHint(this.getItem(position));
}
return convertView;
}
public void setHint(String hint) {
this.hint = hint;
this.notifyDataSetChanged();
this.notifyDataSetInvalidated();
}
public void setSelected(boolean selected) {
this.selected = selected;
}
}
and place where i create MultiSelectSpinner and setTitle
province = (MultiSelectSpinner) findViewById(R.id.subregion);
province.setHint(getResources().getString(R.string.choose_province));
province.setItems(getResources().getStringArray(R.array.provinces));
the problem is that after setHint adapter did not refresh and did not show hint

i just fixed by myself
i throw out SpinnerAdapterProxy and just modify MultiSelectSpinner
by change
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
if (_selection != null) {
String select = null;
if (which < _selection.length) _selection[which] = isChecked;
if (!isAnySelect())
select = _title;
else
select = buildSelectedItemString();
_proxyAdapter.clear();
_proxyAdapter.add(select);
setSelection(0);
}
else {
throw new IllegalArgumentException("Argument 'which' is out of bounds.");
}
}
and
public void setTitle(String title) {
_title = title;
_proxyAdapter.clear();
_proxyAdapter.add(title);
setSelection(0);
}
and added testing finction that test if any item is selected
private boolean isAnySelect() {
for (boolean b : _selection) {
if (b == true) return true;
}
return false;
}

If you use following class you can add hint as following methord
public class MultiSelectionSpinner extends android.support.v7.widget.AppCompatSpinner implements
DialogInterface.OnMultiChoiceClickListener {
String _title;
String[] _items = null;
boolean[] mSelection = null;
ArrayAdapter<String> simple_adapter;
List<KotItems> mKotdata;
int pos;
public MultiSelectionSpinner(Context context)
{
super(context);
simple_adapter = new ArrayAdapter<String>(context,
R.layout.spinneritemstyle);
super.setAdapter(simple_adapter);
}
public MultiSelectionSpinner(Context context, AttributeSet attrs) {
super(context, attrs);
simple_adapter = new ArrayAdapter<String>(context,
R.layout.spinneritemstyle);
super.setAdapter(simple_adapter);
}
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
if (mSelection != null && which < mSelection.length) {
mSelection[which] = isChecked;
simple_adapter.clear();
simple_adapter.add(buildSelectedItemString());
} else {
simple_adapter.add("N/A");
throw new IllegalArgumentException(
"Argument 'which' is out of bounds.");
}
}
#Override
public boolean performClick() {
final AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
builder.setMultiChoiceItems(_items, mSelection, this);
builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface arg0, int arg1)
{
mKotdata.get(pos).setKotnote(buildSelectedItemString());
}
});
builder.show();
return true;
}
#Override
public void setAdapter(SpinnerAdapter adapter) {
throw new RuntimeException(
"setAdapter is not supported by MultiSelectSpinner.");
}
//Add Your Hint in this methord
public void setItems(List<String> items) {
if(items.size()>0){
_items = items.toArray(new String[items.size()]);
mSelection = new boolean[_items.length];
simple_adapter.clear();
simple_adapter.add("Add Your Hint Here");
Arrays.fill(mSelection, false);
}
}
public void setArrayList(List<KotItems> mKotdata,int pos){
this.mKotdata = mKotdata;
this.pos = pos;
}
public void setSelection(int index) {
for (int i = 0; i < mSelection.length; i++) {
mSelection[i] = false;
}
if (index >= 0 && index < mSelection.length) {
mSelection[index] = true;
} else {
throw new IllegalArgumentException("Index " + index
+ " is out of bounds.");
}
simple_adapter.clear();
simple_adapter.add(buildSelectedItemString());
}
private String buildSelectedItemString() {
StringBuilder sb = new StringBuilder();
boolean foundOne = false;
for (int i = 0; i < _items.length; ++i) {
if (mSelection[i]) {
if (foundOne) {
sb.append(", ");
}
foundOne = true;
sb.append(_items[i]);
}
}
System.out.println("u8u8 "+sb.toString());
return sb.toString();
}
}
