I Have a ListView. In my listview I create a custom items on every rows. this custom item as some textviews and two buttons. The problem I have now is I want to detect when the user clicks on the buttons in the listview items.
But My code is not working.
Please don't mind the numerouse text views that are to be hidden from the user only one is to be seen by the user and the two buttons are visible.
Each time I click the button nothing happens, no response
My listview custom item is pasted below.
Thanks for reading my post, am also grateful for your time and effort.

I have 2 TextViews showing on the main UI. I associate each TextView to a unique clickListener that launches a unique AlertDialog for the user to make a selection. The first TextView is launching the second layout for the second AlertDialog rather than the expected first layout for the first AlertDialog. What am I missing here?

Not sure what your textviews' parent is but since you are using attributes like:
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
I guess it is a RelativeLayout.
Since you aren't using neither an orientation nor a relative position, I suppose your TextViews are both on the same line, with just a different margin top, but the quick list TextView has width match_parent and gravity center
android:layout_width="match_parent"
android:gravity="center"
So what's happening is something like this:
And your click always triggers the second TextView that covers entirely the first one.
To fix it change your quick list TextView this way:
<TextView
android:id="#+id/qList"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="8dp"
android:text="quickList"
android:textStyle="bold"
android:textColor="#color/text_primary"
android:layout_centerHorizontal="true"/>
With the attributes:
android:layout_width="wrap_content"
android:layout_centerHorizontal="true"
It will be centered but not overlapping the first TextView.
I hope this could help, if instead I am wrong and your activity_main.xml file differs, please update your code so that it can be easier figure out any alternative problem.
Hello I am developing an application android, I have a problem with a text view that retrieves the data via web service, the data retrieve appears but infringe on the other text view of the page, Here is my code from my xml page:

Then my code that says or go data :
public class DetailEtab extends Activity {
private TextView tv;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.etabdetail);
tv = (TextView) findViewById(R.id.tvl);
tv.setText(search_ville.etabSELECT.getLibelle());
tv = (TextView) findViewById(R.id.tvcp);
tv.setText(search_ville.etabSELECT.getCp());
tv = (TextView) findViewById(R.id.tvv);
tv.setText(search_ville.etabSELECT.getVille());
tv = (TextView) findViewById(R.id.tvp);
tv.setText(search_ville.etabSELECT.getPresentation());
Button btnSa = (Button) findViewById(R.id.btnMa);
btnSa.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(DetailEtab.this, MaterielAssocie.class);
startActivity(intent);
Log.i("ETAB", "servcies associes");
Toast toast = Toast.makeText(getApplicationContext(), "services associes", Toast.LENGTH_SHORT);
toast.show();
}
});
}
}
If anyone can tell me why it does that thanks

You have problems with your layouts. I recommend you to wrap every line into separate LinearLayout and then use LinearLayout to wrap all new LinearLayouts. Also due to long text it's better to wrap parent LinearLayout into Scroll.
NOTE: This is just example that was written inside text box that simply shows main idea and may contain mistakes
Something like this:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent">

android:id="#+id/tvd"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Détail de l'établissement"
android:textSize="20dp"
android:textStyle="bold"/>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content">

android:textStyle="bold"
/>
<TextView
android:id="#+id/tvl"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="libelle"
android:textSize="20dp"
/>

You are assigning tv to multiple different TextViews and then you are assigning multiple values to the last TextView you assign it to.
public class DetailEtab extends Activity {
private TextView tv,tv1,tv2,tv3;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.etabdetail);
tv = (TextView) findViewById(R.id.tvl);
tv.setText(search_ville.etabSELECT.getLibelle());
tv1 = (TextView) findViewById(R.id.tvcp);
tv1.setText(search_ville.etabSELECT.getCp());
tv2 = (TextView) findViewById(R.id.tvv);
tv2.setText(search_ville.etabSELECT.getVille());
tv3 = (TextView) findViewById(R.id.tvp);
tv3.setText(search_ville.etabSELECT.getPresentation());
Button btnSa = (Button) findViewById(R.id.btnMa);
btnSa.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(DetailEtab.this, MaterielAssocie.class);
startActivity(intent);
Log.i("ETAB", "servcies associes");
Toast toast = Toast.makeText(getApplicationContext(), "services associes", Toast.LENGTH_SHORT);
toast.show();
}
});
}
}

I add the childLayout.xml to masterLayout.xml using the following code
TableLayout queryTableLayout = (TableLayout) findViewById(R.id.queryTableLayoutActivity);
LayoutInflater inflater = (LayoutInflater) getSystemService(
Context.LAYOUT_INFLATER_SERVICE);
String courseIDValue = c.getString(courseIdIndex);
View newTagView = inflater.inflate(R.layout.activity_class_activities, null);
queryTableLayout.addView(newTagView, activeClassActivityIndex++);
I want to sort childLayout based on dueDateActivity field. How can I achieve this?
First of all you dont want to sort layouts - you want to sort views that you inflated with certain layout. So there is no "childLayout" there is newTagView.
Your question is a form of more general question: how to reorder n relative child views on a parent layout in certain order. This is not about changing their sizes and positions(that's easy, you just individually because you must know all new params for each) this is about reordering them. This problem breaks into 4:
Note: You can't just copy-paste code, you need to make changes based on what you specifically need (like what Parameter you need and how to compare it)
1. Establish the current order and the order in which they need to be :
use
getChildCount()
to know number of TableLayout children, use
getChildAt(i)
to traverse and access them.
Now make the Map that will determine the transition to the new order.
Map<View, Parameter> map = new HashMap<Integer, Parameter>();
for(int i = 0; i < queryTableLayout.getChildCount(); i++){
map.put(queryTableLayout.getChildAt(i),
queryTableLayout.getChildAt(i).findViewById(R.id.dueDateActivity)
.getParameter());
//since newTagView should inherit all RelativeLayout methods after infation
//getParameter() - the method from TextView(dueDateActivity) you need
Now to make the order right you need to sort the map by parameter,
which in Java 8 looks like
LinkedList<View> ordering = map.entrySet()
.stream()
.sorted(Map.Entry.comparingByValue(new Comparator<Parameter>(){
/*implement your comparator*/
})/*now when stream is sorted collect it to list*/
.collect(Collectors.toList(Map.Entry::getKey);
Now you have your ordering
2. Method to Swap
easiest way to swap views is to swap their layout params
like in this answer
RelativeLayout.LayoutParams params1 = (RelativeLayout.LayoutParams) b1.getLayoutParams();
RelativeLayout.LayoutParams params2 = (RelativeLayout.LayoutParams) b2.getLayoutParams();
b1.setLayoutParams(params2);
b2.setLayoutParams(params1);
Make a method void swap(View A, View B){...} which will work for your RelativeLayout View with that code.
3. Do the thing.
for(int i = 0; i < queryTableLayout.getChildCount(); i++)
swap(queryTableLayout.getChildAt(i), ordering.get(i));
If you want them add dynamically in already sorted place that is much easier You just need to get the right pos, and params like in (1)
and use
public void addView (View child, int index, ViewGroup.LayoutParams params)
According to bedbad's 4 steps I followed first 2 and found solution
I used this answer to help my situation.
This is my sort method (on button click)
public void sortByWeek(View v){
queryTableLayout = (TableLayout) findViewById(R.id.queryTableLayoutActivity);
int childCount = queryTableLayout.getChildCount();
Map<View,String> map = new HashMap<View,String>();
for(int i = 0; i<childCount;i++){
map.put(queryTableLayout.getChildAt(i),((TextView)queryTableLayout.getChildAt(i).findViewById(R.id.dueDateActivity)).getText().toString());
}
Map<View,String> sortedMap = sortByComparator(map,sort);
ArrayList<View> viewSet = new ArrayList<>(sortedMap.keySet());
queryTableLayout.removeAllViews();
for(int i = 0;i<childCount;i++){
queryTableLayout.addView(viewSet.get(i));
}
if(sort){
sort = false;
}
}
public Map<View,String> sortByComparator(Map<View,String> map,final boolean order){
List<Map.Entry<View,String>> list = new LinkedList<Map.Entry<View,String>>(map.entrySet());
Collections.sort(list, new Comparator<Map.Entry<View, String>>() {
#Override
public int compare(Map.Entry<View, String> lhs, Map.Entry<View, String> rhs) {
if(order){
return lhs.getValue().compareTo(rhs.getValue());
}else{
return rhs.getValue().compareTo(lhs.getValue());
}
}
});
Map<View,String> sortedMap = new LinkedHashMap<View,String>();
for(Map.Entry<View,String> entry: list){
sortedMap.put(entry.getKey(),entry.getValue());
}
return sortedMap;
}
I had a Grid Layout inside a Horizontal Scroll View, I'm Trying to Implement a Custom Scroll bar for the Scroll View, So far i'm Able to customize the UI of scroll bar [thumb and seekbar] also set visibility permanent. But problem is i'm stuck at handling events on scroll bar of scrollview. Eg. If user clicks on scroll bar in between the ScrollView should scroll to 50% and so on..like click on 1st qurater scroll view should scroll by 25%.
It's pretty simple if i made my own seekbar and bind it to scroll view, also it provides me methods of it's own and click events and can create objects. But i want to do it using ScrollView's slider. How do i handle scroll view's scrollbar clicks, i can create object of ScrollView class. But How will it controll seekbar?? I do not have onseekbarchangelistner for Horizontall scroll view neither it return any achild view or scrollbar view. also it's seekbar not clickable.

Sorry For Posting this Answer too late:
What is to be done is : Extend a Horizontal Scroll view and override a method onScrollChanged and u get two coordinates x1 and x2. just pass x1 which is real time value indicates how much disance on x axis has been scrolled , to your seekbar setProgress(x1) method. Make sure u set seebar's max value first [setMax()] which is equal to the max scrollable length of scrollView.
public class mHorizontalScrollView extends HorizontalScrollView{
private float progress = 0.0f;
private SeekBar mSeekBar = null;
private MyActivityClass mObj = null;
private float xMax = 0.0f;
public mHorizontalScrollView(Context context, SeekBar sBar)
{
super(context);
mObj = (MyActivityClass) context; //or just use a Static reference
mSeekBar = sBar;
}
#Override
protected void onScrollChanged(int x, int y, int oldX, int oldY) {
// TODO Auto-generated method stub
int myX = x;
if(xMax == 0)
{
xMax = mObj.getMaxScrollWidth(); //Choose Your own Scrollable width or length
mSeekBar.setMax(Math.round(xMax));
}
mSeekBar.setProgress(myX);
super.onScrollChanged(x, y, oldX, oldY);
}
}
It Worked flawlessly. Now to Implement it reverse Scroll on scroll bar and HorizontallScroll View Should scroll in a proper Syncwith seekbar:
Use Below code in main Activity class :
seek_bar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {
#Override
public void onStopTrackingTouch(SeekBar seekBar)
{
}
#Override
public void onStartTrackingTouch(SeekBar seekBar)
{
}
#Override
public void onProgressChanged(SeekBar seekBar, int progress,
boolean fromUser) {
int currScrollPosX = progress;
mHSCV.scrollTo(progress , 0);
// mHSCV is object of mHorizontalScrollView Class
});
}

I have an android activity that when I launch sometimes (about 1 in 4 times) it only draws quarter or half the screen before showing it. When I change the orientation or press a button the screen draws properly.
I'm just using TextViews, Buttons, Fonts - no drawing or anything like that.
All of my code for initialising is in the onCreate(). In this method I'm loading a text file, of about 40 lines long, and also getting a shared preference. Could this cause a delay so that it can't draw the intent?
Thanks in advance if anyone has seen anything similar.
EDIT - I tried commenting out the loading of the word list, but it didn't fix the problem.
EDIT 2 - I didn't manage to resolve the problem, but managed to improve it by adding a timer right at the end of the onCreate. I set a low refresh rate and in the tick changed the text of one of the controls. This then seemed to redraw the screen and get rid of the black portions of the screen.
Here is the activity
