Я хочу, чтобы индикатор выполнения отображался невидимым, когда данные поступают с моего сервера и отображаются в виде списка.
Вот мой код
public class MainActivity extends AppCompatActivity implements AdapterView.OnItemClickListener,Response.ErrorListener, Response.Listener<JSONObject> {
EditText movienameText;
ProgressBar loading;
Button getButton;
ListView moviesList;
ArrayAdapter< String > adapter;
ArrayList< String > moviesname = new ArrayList < String > ();
String x, plot, genre, year;
RequestQueue queue;
JsonObjectRequest request1,request2;
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
movienameText = findViewById(R.id.movienameText);
movienameText.setInputType(InputType.TYPE_TEXT_FLAG_AUTO_COMPLETE);
getButton = findViewById(R.id.getButton);
loading = findViewById(R.id.loading);
moviesList=findViewById(R.id.moviesList);
moviesList.setOnItemClickListener(this);
adapter = new ArrayAdapter < String > (this, android.R.layout.simple_list_item_1,moviesname);
}
public void get(View view) {
moviesname.clear();
queue = Volley.newRequestQueue(this);
String url1 = "http://www.omdbapi.com/?s="+movienameText.getText().toString().replace(" ","%20")+"&apikey=private";
request1 = new JsonObjectRequest( Request.Method.GET, url1, null, this, this);
queue.add(request1);
}
@Override public void onResponse(JSONObject response) {
if (response.toString().contains("Search")) {
try {
for (int i = 0; i < response.getJSONArray("Search").length(); i++) {
if (i < response.getJSONArray("Search").length()) {
moviesname.add(response.getJSONArray("Search").getJSONObject(i).getString("Title"));
} else {
break;
}
}
moviesList.setAdapter(adapter);
} catch (JSONException e) {
Toast.makeText(this, "Error Occured, Try Again", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
else{
try {
genre = response.getString("Genre");
plot = response.getString("Plot");
year = response.getString("Year");
} catch (JSONException e) {
Toast.makeText(this, "Error Occured, Try Again", Toast.LENGTH_SHORT).show();
e.printStackTrace();
}
}
}
@Override public void onErrorResponse(VolleyError error) {
Toast.makeText(this, "Check Internet Connection", Toast.LENGTH_SHORT).show();
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String url2 = "http://www.omdbapi.com/?t="+moviesList.getItemAtPosition(position).toString().replace(" ","%20")+"&apikey=private";
request2 = new JsonObjectRequest(Request.Method.GET, url2, null, this, this);
queue.add(request2);
Handler handler=new Handler();
handler.postDelayed(new Runnable() {
@Override
public void run() {
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setMessage("Release date: "+year+"\n"+"\n"+
"Genre: "+genre+"\n"+"\n"+
"Plot: "+plot).create().show();
}
},1000);
}
@Override
public void onPointerCaptureChanged(boolean hasCapture) {
}
}
