Make sure you set your id in listview as android:id="#android:id/list"

try changing this
ListView lv = getListView();
to
ListView lv = (ListView)findViewById(android.R.id.list);
where the id of the listview is "android:id/list"

How to solve the error like java.lang.Throwable: setStateLocked?

I am developing an app. In it I'm using a listview. When I click on list item, it should go to next activity, i.e ProfileActivity2.java. It works fine, but in this ProfileActivty2 there is a button at the bottom and when I click on this button my app gets crashed and stopped in listview page. And shows the error java.lang.Throwable: setStateLocked in listview layout file i.e At setContentView. How do I solve this error?

I think the error is at this line inside btn.setOnClickListener of getview block just use startActivity(intent);

Because while calling this constructor:
CustomListAdapterfriend(Context context, List<HashMap<String, Object>> models)
You are providing getApplicationContext(). Try to provide context of the activity.
Edit 1:
Following the comments:
CustomListAdapterfriend adapter = new CustomListAdapterfriend(Friendsprofile.this, usersList); lv.setAdapter(adapter);
Modify the constructor of your adapter class from
public CustomListAdapterfriend(Context context, List<HashMap<String, Object>> models)
to
public CustomListAdapterfriend(Activity context, List<HashMap<String, Object>> models)
So whenever you call the constructor, the IDE will notify you to provide an Activity as a parameter, so the cast in your adapter won't fail.
While using in fragments try requireActivity() instead of getApplicationContext()
CustomListAdapterfriend(requireActivity(), List<HashMap<String, Object>> models)

how to display details of single item of list in another activity from url (json data)?

I have written a program to display the list of json data from a url which has an image and 5 textviews which is displaying perfectly.
Url : https://itunes.apple.com/search?term=jack+johnson&limit=50.
When i click on an item from the list i want to display the details of that item in another activity based on the track-id
Url : https://itunes.apple.com/lookup?id=659234741
So when i click on the item the details are getting displayed in the textview , but by default it is displaying the details of id = 659234741 for some items or in short the details does not match.
Need some help to figure out the problem

Thank you
The problem is that you are initializing the resultp each element in your getView method, so therefore the last id/element of the listview adapter's data will be considered as the resultp.
Im sure that the id 659234741 is the last element, which will always be the id for each onclick that would happen.
A solution for this is to create a final resultp within your getView method instead of having just one global resultp.
final HashMap<String, String> resultp = data.get(position);

Here my SingleMenuItemActivity.java
public class SingleMenuItemActivity extends Activity{
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.single_list);
Intent i = getIntent();
//now your item data are in i
String TAG_ID_RS = i.getStringExtra("TAG_ID_RS");
String TAG_NAMA_RS = i.getStringExtra("TAG_NAMA_RS");
String TAG_LINK_IMAGE_RS = i.getStringExtra("TAG_LINK_IMAGE_RS");
String TAG_ALAMAT_RS = i.getStringExtra("TAG_ALAMAT_RS");
String TAG_TELEPON_RS = i.getStringExtra("TAG_TELEPON_RS");
String TAG_HARGA_RS = i.getStringExtra("TAG_HARGA_RS");
TextView namaView = (TextView) findViewById(R.id.nama_rs);
ImageView link_img = (ImageView) findViewById(R.id.image_rs);
TextView alamat = (TextView) findViewById(R.id.alamat_rs);
TextView telepon = (TextView) findViewById(R.id.telepon_rs);
TextView harga = (TextView) findViewById(R.id.harga_rs);
namaView.setText(TAG_NAMA_RS);
//link_img.setImageBitmap(TAG_LINK_IMAGE_RS);
alamat.setText(TAG_ALAMAT_RS);
telepon.setText(TAG_TELEPON_RS);
harga.setText(TAG_HARGA_RS);
}
}
In your main activity's onCreate method, after your last line add:
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View v, int position, long id) {
HashMap<String,String> item = (HashMap<String,String>) adapter.getItem(position);
Intent intent = new Intent(this, YourSecondActivity.class);
intent.putExtra("TAG_ID_RS", item.get("TAG_ID_RS"));
intent.putExtra("TAG_NAMA_RS", item.get("TAG_NAMA_RS"));
......
startActivity(intent);
}
});
In the YourSecondActivity.java there goes something like:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_yoursecondactivity);
Intent i = getIntent();
//now your item data are in i
String TAG_ID_RS = i.getString("TAG_ID_RS");
String TAG_NAMA_RS = i.getString("TAG_NAMA_RS");
....
TextView namaView = (TextView)findViewById(R.id.yourNameView);
namaView.setText(TAG_NAMA_RS);
....
}
For your intent receiving activity you need to define an intent filter in the manifest file:
<activity android:name="SingleMenuItemActivity">
<intent-filter>
<action android:name="yourpackage.intent.action.showsinglemenuitem"/>
</intent-filter>
</activity>
Use the "yourpackage.intent.action.showsinglemenuitem" action name when constructing the INTENT to be p
I think I found out your problem finally:
In your MainActivity you define your field names as for example:
public static final String TAG_NAMA_RS = "nama_rs";
and you fill them with that name into the Intent,
but in your SingleMenuItemActivity you are trying to access them with different name:
String TAG_NAMA_RS = i.getStringExtra("TAG_NAMA_RS");
you need to do
String TAG_NAMA_RS = i.getStringExtra("nama_rs");
