I've tried my best to find where the error is, but cannot find it.

You missed an important part in your code, setContentView()
add it in you onCreate() right after super() call
Should be working then
public class PropertyHome extends AppCompatActivity
{
private RecyclerView recyclerView;
private RecyclerView.Adapter recyclerAdapter;
private RecyclerView.LayoutManager recyclerLayoutManager;
...
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_property_homr); // add setContentView here
try {
recyclerView = (RecyclerView)findViewById(R.id.get_property_entry_property_home);
String[] myRecycler = new String[5];
myRecycler[0] = "Recycler 1";
myRecycler[1] = "Recycler 2";
myRecycler[2] = "Recycler 3";
myRecycler[3] = "Recycler 4";
myRecycler[4] = "Recycler 5";
recyclerAdapter = new GetPropertyRecyclerViewAdapater(myRecycler);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(recyclerAdapter);
}
catch(Exception e)
{
Toast.makeText(PropertyHome.this, "Error: " + e.toString(), Toast.LENGTH_LONG).show();
}
}

Some Recyclerview Items Affect Each Other

I have recyclerview with many items. And this is a screenshot of my application, showing the first item of my recyclerview.
pict of my page
but when I change the choice of the fifth item, the choice of the first item is changing too. Any idea why this is happening? And what should I do?
this is my adapter:
public class SkoringAdapter extends RecyclerView.Adapter<SkoringAdapter.SkoringViewHolder>{
private List<Skoring> skoringList;
private Context context;
public SkoringAdapter(final Context context) {
this.skoringList = new ArrayList<>();
this.context = context;
}
public void setSkoringList(List<Skoring> skoringList){
this.skoringList.clear();
this.skoringList.addAll(skoringList);
notifyDataSetChanged();
}
static class SkoringViewHolder extends RecyclerView.ViewHolder{
Context context;
TextView tvSoal, tvKe, tvTotal, tvProses;
RadioGroup rgPilihan;
RadioButton rb1, rb2, rb3, rb4, rb5, rb6;
SkoringViewHolder(View itemView, final Context context) {
super(itemView);
this.context = context;
tvSoal = itemView.findViewById(R.id.tvSoal);
...etc
}
}
#NonNull
#Override
public SkoringViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_skoring, parent, false);
return new SkoringViewHolder(itemView,context);
}
#Override
public void onBindViewHolder(#NonNull final SkoringViewHolder holder, final int position) {
final Skoring tg = skoringList.get(position);
holder.tvSoal.setText(tg.getSoal());
holder.tvKe.setText(Integer.toString(position + 1));
holder.tvTotal.setText(Integer.toString(skoringList.size()));
holder.rgPilihan.setVisibility(View.GONE);
holder.rb1.setVisibility(View.GONE);
holder.rb2.setVisibility(View.GONE);
holder.rb3.setVisibility(View.GONE);
holder.rb4.setVisibility(View.GONE);
holder.rb5.setVisibility(View.GONE);
holder.rb6.setVisibility(View.GONE);
String[] kunci = tg.getKunci().split("`");
String[] pilihan = new String[kunci.length];
String[] isi = new String[kunci.length];
String[] skor = new String[kunci.length];
for (int i=0; i<kunci.length; i++){
String[] pisah = kunci[i].split("~");
if(pisah.length == 3){
pilihan[i] = pisah[0]; isi[i] = pisah[1]; skor[i] = pisah[2];
}
}
holder.rgPilihan.setVisibility(View.VISIBLE);
if(kunci.length > 0){
holder.rb1.setText(isi[0]);
holder.rb1.setVisibility(View.VISIBLE);
if(kunci.length > 1){
holder.rb2.setText(isi[1]);
holder.rb2.setVisibility(View.VISIBLE);

holder.rb4.setVisibility(View.VISIBLE);
if(kunci.length > 4){
holder.rb5.setText(isi[4]);
holder.rb5.setVisibility(View.VISIBLE);
if(kunci.length > 5){
holder.rb6.setText(isi[5]);
holder.rb6.setVisibility(View.VISIBLE);
}}}}}}}}

Solved with adding this on my java class:
MyrecyclerView.setItemViewCacheSize(100);

Android Custom Adapter not displaying any data in Activity?

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.

Please help..

There is nothing in your activity layout with android:id="#+id/LinearContainer, and so FragmentManager does not have anywhere to place your DetailsFragment.

setOnClickListener is not getting called on image view

I want to call one fragment onclick of next image view. So I have put OnClickListener on image view but it is not getting called at all..
What can be the issue??

Please Help...

why are you using these below lines of code, please remove them and check the effect:-
android:clickable="true"
next.setClickable(true);
It's not realize to work but it works in maximum cases.
If you set the view to be clickable, then it will consume the click and not propagate it to the container.

switch to another activity with swipe is not working

My requirement :-
I have two activities..When I swipe it will go to another activity..
So,I have :--
MainActivity.java
public class MainActivity extends Activity {
private GestureDetectorCompat gestureDetectorCompat;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_getservice);
gestureDetectorCompat = new GestureDetectorCompat(this, new MyGestureListener());
}
#Override
public boolean onTouchEvent(MotionEvent event) {
this.gestureDetectorCompat.onTouchEvent(event);
return super.onTouchEvent(event);
}
class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
//handle 'swipe left' action only
#Override
public boolean onFling(MotionEvent event1, MotionEvent event2,
float velocityX, float velocityY) {
if(event2.getX() < event1.getX()){
//switch another activity
Intent intent = new Intent(
MainActivity.this, Join_form.class);
startActivity(intent);
finish();
}
return true;
}
}
}
and Join_form.java
public class Join_form extends Activity {
private GestureDetectorCompat gestureDetectorCompat;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gestureDetectorCompat = new GestureDetectorCompat(this, new MyGestureListener());
}
#Override
public boolean onTouchEvent(MotionEvent event) {
this.gestureDetectorCompat.onTouchEvent(event);
return super.onTouchEvent(event);
}
class MyGestureListener extends GestureDetector.SimpleOnGestureListener {
//handle 'swipe left' action only
#Override
public boolean onFling(MotionEvent event1, MotionEvent event2,
float velocityX, float velocityY) {
if(event2.getX() > event1.getX()){
//switch another activity
Intent intent = new Intent(
Join_form.this, MainActivity.class);
startActivity(intent);
finish();
}
return true;
}
}
}

But I can not swipe the page. It is not going to the another page. Why it is happening?
Where is the problem?

Agree with #k3v1n4ud3. Let me just expand a bit since I can't really comment due to lack of karma.
With ViewPager (inside MainActivity.java) + MainFragment (Fragment)+ JoinForm (Fragment), you would be able to get away without having a listener for fling. It would just handle the swiping part automatically for you.
Just think about it like this: You have a brain (MainActivity w/ViewPager) and two arms (the first and second fragment you're implementing).
Create a MainActivity that would contain your ViewPager.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myViewPager = (ViewPager) findViewById(R.id.myViewPager);
//somehow fill the adapter
MyAdapter myAdapter = new MyAdapter(getSupportFragmentManager(), getApplicationContext()); //=== required as per the MyAdapter class
//set the adapter
myViewPager.setAdapter(myAdapter);
// display first fragment
myViewPager.setCurrentItem(0);
}
Create an Adapter that extends FragmentPagerAdapter (or FragmentStatePagerAdapter). It looks like this:
class MyAdapter extends FragmentPagerAdapter {
private final int[] titles = {R.string.main_activity_title, R.string.join_activity_title};
private final String[] fragments = {
MainFragment.class.getName(),
JoinFragment.class.getName()
};
private final Context ctx;
public MyAdapter(FragmentManager fm, Context ctx) {
super(fm);
this.ctx = ctx;
}
#Override
public CharSequence getPageTitle(int position) {
return ctx.getString(titles[position]);
}
#Override
public Fragment getItem(int position) {
return Fragment.instantiate(ctx, fragments[position]);
}
#Override
public int getCount() {
return titles.length;
}
}
(Optional) See those title thingys on top of each page, the ones you could click so you could fast forward to the other page? They're called tabhosts.
To use them, simply add a tabhost to your MainActivity layout and add this logic in MainActivity.java:
myViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// when user do a swipe the selected tab change
myTabHost.setSelectedNavigationItem(position);
}
});
//set titles
for (int i = 0; i < myAdapter.getCount(); i++) {
myTabHost.addTab(
myTabHost.newTab()
.setText(myAdapter.getPageTitle(i))
.setTabListener(this)
);
}
4. (Optional) Animations on 'fling'
So to animate when you switch fragments, you simple have to call this:
myViewPager.setPageTransformer(true, new DefaultTransformer());
And you can also customize it to your will.
I apologize if there are typos and other stuff. But this should cover majority of what you need.

You probably should change the architecture, transform your 2 activities into fragment and place them inside a viewPager. The viewPager will handle the sliding part for you.
