I have a view in an activity as below .I want to set Margin to the view.But i used Viewgroup.LayoutParams but it doesn't change the view of the row.Below i have given custom adapter which takes data from firstpagerowitems.xml.I have given the java code for adapter .I tried doing android:layout_marginbottom="10dp" for firstpagerowitems.xml and firstpage.xml but it doesnt work.
class MyAdapter extends ArrayAdapter<String> {
Context context;
ArrayList<String> rTitle;
ArrayList<String> rDescription;
ArrayList<String> rImgs;
MyAdapter (Context c, ArrayList<String> title,ArrayList<String> description,ArrayList<String> imgs) {
super(c, R.layout.firstpagerowitems, R.id.textView1, title);
this.context = c;
this.rTitle = title;
this.rDescription = description;
this.rImgs = imgs;
}
#NonNull
#Override
public View getView(int position, #Nullable View convertView, #NonNull ViewGroup parent) {
LayoutInflater layoutInflater = (LayoutInflater)getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = layoutInflater.inflate(R.layout.firstpagerowitems, parent, false);
TextView images = row.findViewById(R.id.textView3);
TextView myTitle = row.findViewById(R.id.textView1);
TextView myDescription = row.findViewById(R.id.textView2);
Log.d("entered last","yes");
Log.d("postion", String.valueOf(position));
Log.d("rimgs", String.valueOf(rImgs));
Log.d("desc", String.valueOf(rDescription));
Log.d("title", String.valueOf(rTitle));
// now set our resources on views
images.setText(rImgs.get(position));
myTitle.setText(rTitle.get(position));
myDescription.setText(rDescription.get(position));
Random random=new Random();
int trp=random.nextInt(16);
Log.d("enteredcolor",mycolors[trp]);
// images.setBackgroundResource(R.color.lightgreen);
String fd=mycolors[trp];
// images.setBackgroundColor(Color.parseColor(fd));
// LinearLayout mylinear=row.findViewById(R.id.mylinear);
// mylinear.setBackgroundColor(Color.parseColor(fd));
row.setBackgroundColor(Color.parseColor(fd));
// ViewGroup.MarginLayoutParams margins=new ViewGroup.MarginLayoutParams(row.getLayoutParams());
// margins.setMargins(0,100,0,100);
// ViewGroup.LayoutParams layouts=new ViewGroup.LayoutParams(margins);
// row.setLayoutParams(layouts);
// ViewGroup.LayoutParams params=new ViewGroup.LayoutParams(row);
return row;
}

I have a custom listview, inside of which there is another one. And the one that is nested will not scroll. Perhaps you need to register something in the parent setOnTouchListener? I don't have anything like that in getView.

I have an ExpandableListView in my app. I want to make the child layout a bit narrower than the group header and also keep it centered. Due to some visual effects i must set layout params from code however i can't seem to find the best solutions for this tried changing layout width from xml with no luck. Any advice will be helpful.
Thanks

I'd put all Views in one single ConstraintLayout. By attaching the background to the parent left and right, the View is default centered. By adding margins left and right, you achieve the View being smaller.
Like in this example:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imageView2"
android:layout_width="0dp"
android:layout_height="?attr/actionBarSize"
android:layout_marginBottom="8dp"
android:layout_marginEnd="16dp"
android:layout_marginStart="16dp"
android:layout_marginTop="8dp"
android:background="#android:color/darker_gray"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<CheckBox
android:id="#+id/checkBox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:buttonTint="#android:color/background_light"
android:text="CheckBox"
android:textColor="#android:color/background_light"
app:layout_constraintBottom_toBottomOf="#+id/imageView2"
app:layout_constraintStart_toStartOf="#+id/imageView2"
app:layout_constraintTop_toTopOf="#+id/imageView2" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="8dp"
android:layout_marginStart="24dp"
android:layout_marginTop="8dp"
android:text="Stuff"
android:textColor="#android:color/background_light"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toEndOf="#+id/checkBox"
app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>
which looks like this:
the
android:layout_width="0dp"
actually means the view will be stretched to match the constraints. A bit like "match_parent", but within the bounds you set via its constraints.
Play around with the ConstraintLayout a bit. Once you get the hang of it, you will not want to miss it anymore :)
I have created a custom adapter for my list (JobAdapter), however, whenever I set the adapter, even if there are values (jobs arraylist parameter has a size of 2), nothing is displayed on my activity.
This is my adapter:
public class JobAdapter extends ArrayAdapter<Job> {
private final Context context;
private final ArrayList<Job> jobs;
private final int layoutResourceId;
public JobAdapter(Context context, int layoutResourceId, ArrayList<Job> jobs) {
super(context, layoutResourceId, jobs);
this.context = context;
this.jobs = jobs;
this.layoutResourceId = layoutResourceId;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = convertView;
ViewHolder holder = null;
LayoutInflater inflater = (LayoutInflater) context.getSystemService((Activity.LAYOUT_INFLATER_SERVICE));
if (view == null) {
view = inflater.inflate(layoutResourceId, parent, false);
holder = new ViewHolder();
holder.title = (TextView)view.findViewById(R.id.tv_jobTitle);
holder.payrate = (TextView)view.findViewById(R.id.tv_payRate);
holder.startdate = (TextView)view.findViewById(R.id.tv_startDate);
holder.workinghrs = (TextView)view.findViewById(R.id.tv_duration);
holder.location = (TextView)view.findViewById(R.id.tv_location);
holder.companyname = (TextView)view.findViewById(R.id.tv_companyName);
holder.description = (TextView)view.findViewById(R.id.tv_JobDesc);
holder.experience = (TextView)view.findViewById(R.id.tv_experienceReq);
holder.equipment = (TextView)view.findViewById(R.id.tv_equipmentReq);
view.setTag(holder);
} else {
holder = (ViewHolder)view.getTag();
}
Job j = jobs.get(0);
holder.title.setText(j.getJobTitle());
holder.payrate.setText(j.getPayrate());
holder.startdate.setText(j.getDurationStart());
holder.workinghrs.setText(j.getWorkingHrs());
holder.location.setText(j.getLocation());
holder.companyname.setText("ABC Company");
holder.description.setText(j.getDescription());
holder.experience.setText("3-5 years");
holder.equipment.setText("Hardhat");
//TODO: add hardhat, boots and other field to objects mapped
return view;
}
static class ViewHolder
{
TextView title;
TextView payrate;
TextView startdate;
TextView workinghrs;
TextView location;
TextView companyname;
TextView description;
TextView experience;
TextView equipment;
}
}
This is how I am setting the adapter in the AsyncTask OnPostExecute:
protected void onPostExecute(ArrayList<Job> result) {
arrayAdapter = new JobAdapter(getApplicationContext(), R.layout.jobcard, result);
arrayAdapter.notifyDataSetChanged();
flingContainer.setAdapter(arrayAdapter);
}
What could be the problem with this? There is no error message in Logcat and the application still runs fine, just no data shown. Data should be shown in the jobcard.xml layout which is defined for the JobAdapter.
Thanks in advance for any help with this!
EDIT:
It looks like getView() in the JobAdapter is not being called, I have tried to override the getCount() method in the JobAdapter to return 1 just so I can see one element but that did not work either.

I am making some changes to an XML layout side of my application. There is a ImageView I am trying to bring to the front yet when I do the app crashes and I can seem to tell why.
Working XML:

Basically what I am looking for is my rows in my ListView to look something like this:
Title: Harry Potter
Hardcover: Yes
Own: No
Country: United States
Can someone post the XML layout of one of these rows? I can't seem to get it right with my code.
Here is what I have that just is plain wrong and not working:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableLayout
android:id="#+id/tableLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stretchColumns="0"
>
<TableRow
android:id="#+id/tableRow1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/txtKey"
android:layout_height="fill_parent"
android:layout_gravity="left"
android:textSize="18dip"
android:layout_marginLeft="8dip"
android:textStyle="bold"
android:layout_marginTop="2dp"
android:layout_marginBottom="2dp"
android:text="test"
/>
<TextView
android:id="#+id/txtValue"
android:layout_height="fill_parent"
android:layout_gravity="right"
android:textSize="18dip"
android:layout_marginRight="8dip"
android:layout_marginTop="2dp"
android:layout_marginBottom="2dp"
android:text="test2"
/>
</TableRow>
</TableLayout>
</LinearLayout>
Got it.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">

<TableRow

android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<TextView
android:id="#+id/txtKey"
android:text="Some text"
android:textSize="18dip"
android:textStyle="bold"
android:layout_marginLeft="8dip"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="left"
android:layout_weight="1.0"
android:layout_marginTop="2dp"
android:layout_marginBottom="2dp"
/>
<TextView
android:id="#+id/txtValue"
android:text="Some text"

android:layout_height="wrap_content"
android:gravity="right"
android:layout_weight="1.0"
android:layout_marginTop="2dp"
android:layout_marginBottom="2dp"
/>
</TableRow>
</TableLayout>
</LinearLayout>
res/layout/listitem.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_weight="1"
android:gravity="right"
android:layout_gravity="right"

</LinearLayout>
then in your activity:
ListView listView = (ListView) findViewById(R.id.list);
listView.setAdapter(new BaseAdapter() {
final String[][] keysAndValues = {
{"key1", "value1"},
{"key2", "value2"},
{"key3", "value3"}
};
#Override
public int getCount() {
return keysAndValues.length;
}
#Override
public String[] getItem(int position) {
return keysAndValues[position];
}
#Override
public long getItemId(int position) {
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
TextView[] foundTextFields;
if(convertView == null) {
convertView = LayoutInflater.from(parent.getContext()).inflate(
R.layout.listitem, parent, false);
foundTextFields = new TextView[] {
(TextView) convertView.findViewById(R.id.textLeft),
(TextView) convertView.findViewById(R.id.textRight)
};
convertView.setTag(foundTextFields);
}
else {
foundTextFields = (TextView[]) convertView.getTag();
}
String[] item = getItem(position);
foundTextFields[0].setText(item[0]);
foundTextFields[1].setText(item[1]);
return convertView;
}
});
