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?

Try this;
Your image is in String so do this

// byte[] b = str1.getBytes();
byte[] ba2 = Base64.decode(str1 ,Base64.DEFAULT);
Bitmap bitmap = BitmapFactory.decodeByteArray(ba2, 0, ba2.length);

your php code must be become
base64_encode(base64_decode($row["TAG_Prix_Photo"]));

search filter for Listview [duplicate]

I'm a beginner, I'm creating a job search app which shows job infomation as listview where the data is from WAMP server database.

getStringArrayList is a method on Bundle (such as savedInstanceState). There's no such method in Activity. Hope that helps.
Currently your infoList is an ArrayList>, something that is harder to pass directly to an activity. So find a way to represent it as an ArrayList, or find a more suitable datatype supported by Intent's putExtra-methods. Here below is a suggested solution using an ArrayList.
Passing the data into the activity with the Intent allows you to get it back in your SearchFilter. In the calling activity put something like this:
Intent i = new Intent(this, SearchFilter.class);
i.putStringArrayListExtra("com.yourpackagename.here.keynamehere", aStringArrayList);
In SearchFilter.java, put something like this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
filterText = (EditText) findViewById(R.id.search_box);
filterText.addTextChangedListener(filterTextWatcher);
Intent startingIntent = getIntent();
ArrayList<String> arrayList = new ArrayList<String>();
if (startingIntent != null) {
arrayList = startingIntent.getStringArrayList("com.yourpackagename.here.keynamehere");
}
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,
arrayList));
}

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.

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);

Listview error,android stopped working

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"
