Text doen't appear after speech in adroid studio

Today i am posting my first question here in stackoverflow.
My app's subject is speech to text application all the app is working but the text doen't appear in its zone after saying the speech. So i am here asking you all for help.
Belong my xml file :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="match_parent"
tools:context=".MainActivity">
<EditText
android:id="#+id/edittext"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:hint="Tap Mic to Speak"

</RelativeLayout>
And my main code:
package com.example.translationapp;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
checkPermission();

if (matches != null) {
edittext.setText(matches.get(0));
}
}

#Override
public void onEvent(int i, Bundle bundle) {
}
});
findViewById(R.id.button).setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View view, MotionEvent motionEvent) {
switch (motionEvent.getAction()) {
case MotionEvent.ACTION_UP:
mSpeechRecognizer.stopListening();
edittext.setHint("You will see input here");
break;
case MotionEvent.ACTION_DOWN:
mSpeechRecognizer.startListening(mSpeechRecognizerIntent);
edittext.setText("");
edittext.setHint("Listening...");
break;
}
return false;
}
});
}
private void checkPermission() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (!(ContextCompat.checkSelfPermission(this, Manifest.permission.RECORD_AUDIO) == PackageManager.PERMISSION_GRANTED)) {

So please again and thank you all for your time.

Google Map is not movable

Hey guys I am creating an app which gets the current co-ordinates of the user and then show them on the map which is implemented on the activity.
But my problem is that the map is not movable. I have tried getUiSettings().setScrollGesturesEnabled(true); but its not working.
The Code is given below:
public class Page1 extends AppCompatActivity implements OnMapReadyCallback {
private GoogleMap mMap;
String em,n;
private DrawerLayout mDrawer;
private Toolbar toolbar;
private NavigationView nvDrawer;
TextView tv1;

mapFragment.getMapAsync(this);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
nvDrawer = (NavigationView) findViewById(R.id.nvView);
setupDrawerContent(nvDrawer);
// Find our drawer view

// Tie DrawerLayout events to the ActionBarToggle

inflater.inflate(R.menu.my_menu_option, menu);

you are getting location from Network provider , this takes time
what about add location.LocationListener
public class Page1 extends AppCompatActivity implements OnMapReadyCallback,location.LocationListener {
#Override
public void onLocationChanged(Location location)
{
CameraPosition position = new CameraPosition.Builder()
.target(new LatLng(Location.getLatitude, Location.getLongitude))
.zoom(17).build();
mMap.animateCamera(CameraUpdateFactory.newCameraPosition(position));
}
}

How can i only show a webview Fragment once loading has complete

Is there anyway of showing only my webview once loading has complete? at the moment i have a little webview Fragment on my homescreen but it takes a while to load.I want to show only once loading completes because at the moment its a white screen until loading completes.This does not look the greatest. I tried to add a progress bar but for some reason that does not work in my fragment either.
Ive tried to add the code posted as an answer but it makes no difference. i think its because it a fragment that im having the issues as the progress par works in my main activity webviews.
public class WebViewFragment extends Fragment {
WebView wv;
private String NEWS = "mywebsite goes here";
#Override
public void onSaveInstanceState(Bundle outState) {
wv.saveState(outState);
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Checks the orientation of the screen
if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) {
Toast.makeText(getContext(), "landscape", Toast.LENGTH_SHORT).show();
} else if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
Toast.makeText(getContext(), "portrait", Toast.LENGTH_SHORT).show();
}
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final ProgressBar Pbar;
View view = inflater.inflate(R.layout.webviewfrag, null, false);
if (savedInstanceState == null) {
((WebView )view.findViewById(R.id.NewsFeedWbview)).restoreState(savedInstanceState);
wv = (WebView) view.findViewById(R.id.NewsFeedWbview);
wv.setScrollbarFadingEnabled(false);
Pbar = (ProgressBar) view.findViewById(R.id.pBwvf);
final TextView tv = (TextView) view.findViewById(R.id.tV69);
wv.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
if (progress < 100 && Pbar.getVisibility() == ProgressBar.GONE) {
Pbar.setVisibility(ProgressBar.VISIBLE);
tv.setVisibility(View.VISIBLE);
}
Pbar.setProgress(progress);
if (progress == 100) {
Pbar.setVisibility(ProgressBar.GONE);
tv.setVisibility(View.GONE);
}
}
});
wv.getSettings().setJavaScriptEnabled(true);
wv.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
wv.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
wv.getSettings().setLoadsImagesAutomatically(true);
wv.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
if (Build.VERSION.SDK_INT >= 19) {
// chromium, enable hardware acceleration
wv.setLayerType(View.LAYER_TYPE_HARDWARE, null);
} else {
// older android version, disable hardware acceleration
wv.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
wv.canGoBackOrForward(5);
wv.getSettings().setLoadWithOverviewMode(true);
wv.getSettings().setUseWideViewPort(true);
wv.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
wv.setPadding(0, 0, 0, 0);
wv.loadUrl(NEWS);
}
return view;
}
}

Here my code:
Activity:
public class WebViewActivity extends Activity {
private WebView webView;
private EditText urlEditText;
private ProgressBar progress;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);

webView = (WebView) findViewById(R.id.webView);
webView.setWebChromeClient(new MyWebViewClient());
progress = (ProgressBar) findViewById(R.id.progressBar);
progress.setMax(100);
Button openUrl = (Button) findViewById(R.id.goButton);
openUrl.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View view) {
String url = urlEditText.getText().toString();
if (validateUrl(url)) {
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(url);
WebViewActivity.this.progress.setProgress(0);
}
}
private boolean validateUrl(String url) {
return true;
}
});
}
private class MyWebViewClient extends WebChromeClient {
#Override
public void onProgressChanged(WebView view, int newProgress) {
WebViewActivity.this.setValue(newProgress);
super.onProgressChanged(view, newProgress);
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.web_view, menu);
return true;
}
public void setValue(int progress) {
this.progress.setProgress(progress);
}
}
Layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".WebViewActivity" >
<LinearLayout
android:id="#+id/urlContainer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<EditText
android:id="#+id/urlField"
android:layout_width="wrap_content"

android:hint="Enter URL to open" />
<Button
android:id="#+id/goButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

Adding a progress spinner to app while data from volley loads

I'm trying to add a progress spinner at the top of my app while data is being received from the volley. There may be an easier way to do this but this is what i've tried so far only I have a few errors. The first error being newsListView getting the error 'varied is accessed from within inner class, needs to be declared final'. and the string values cannot be resolved. Here is the class I made within the oncreate method:
public class MainActivity extends AppCompatActivity {
private List<NewsRecord> newsListData = new ArrayList<NewsRecord>();
private GridView newsListView;
private NewsListAdapter adapter;
LinearLayout layout;
private ProgressDialog pDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GridView newsListView = (GridView) findViewById(R.id.newsFeedList);
adapter = new NewsListAdapter(this, R.layout.adapter_news_list, newsListData, this);
layout = (LinearLayout) findViewById(R.id.progressbar_view);
newsListView.setAdapter(adapter);
pDialog = new ProgressDialog(this);
// Showing progress dialog before making http request
pDialog.setMessage("Loading Articles...");
pDialog.show();
newsListView.setOnItemClickListener(itemClicked);
nextStart = 0;
updateListData(nextStart, 20);
}
public int nextStart = 0;
public void updateListData(int StartPoint, int count){
String url = "http://www.efstratiou.info/projects/newsfeed/getList.php?start=" + StartPoint + "&count=" + count;
EDANewsApp app = EDANewsApp.getInstance();
JsonArrayRequest jsonRequest = new JsonArrayRequest(url, listener, errorListener);
app.requestQueue.add(jsonRequest);
nextStart +=count;
}
#Override
public boolean onCreateOptionsMenu (Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
#Override
public void onDestroy() {
super.onDestroy();
hidePDialog();
}
private void hidePDialog() {
if (pDialog != null) {
pDialog.dismiss();
pDialog = null;
}
}
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()) {
case R.id.action_about:
Intent intent = new Intent(this, AboutActivity.class);
startActivity(intent);
return true;
case R.id.action_search:
return true;
case R.id.action_settings:
return true;
default:
return super.onOptionsItemSelected(item);
}
}
AdapterView.OnItemClickListener itemClicked = new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(MainActivity.this, NewsItemActivity.class);
intent.putExtra("newsItemId", newsListData.get(position).recordId);
startActivity(intent);
}
};
private SearchView.OnQueryTextListener searchQueryListener = new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
Intent searchIntent = new Intent(MainActivity.this, SearchResultsActivity.class);
searchIntent.putExtra("query", query);
return true;
}
#Override
public boolean onQueryTextChange(String newText) {
return false;
}
};
//Listeners
Response.Listener<JSONArray> listener = new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
//we successfully received the JSONArray
//Here we will extract the data and use it in our app
hidePDialog();
//Clear the dataset before loading new data
// newsListData.clear();
//Go through all the JSON objects
for (int i = 0; i < response.length(); i++) {
try {
//Get one JSON object
JSONObject jsonObj = response.getJSONObject(i);
//Put JSON data in a Java object
NewsRecord record = new NewsRecord();
record.recordId = jsonObj.getInt("record_id");
record.title = jsonObj.getString("title");
record.date = jsonObj.getString("date");
record.shortInfo = jsonObj.getString("short_info");
record.imageUrl = jsonObj.getString("image_url");
newsListData.add(record);
} catch (JSONException e) {
e.printStackTrace();
}
}
adapter.notifyDataSetChanged();
}
};
Response.ErrorListener errorListener = new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
//There was an error in the communication
//We can notify the user about it
hidePDialog();
}
};
}
and the progress bar appears in the activity_main.xml like so:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/newsListItem"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context=".MainActivity">
<LinearLayout
android:id="#+id/progressbar_view"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:orientation="horizontal" >
<ProgressBar
style="?android:attr/progressBarStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical|center_horizontal"
android:text="Loading data..." />
</LinearLayout>
<View
android:layout_width="fill_parent"
android:layout_height="1dp"
android:background="#C0C0C0" />
</LinearLayout>
<GridView
android:id="#+id/newsFeedList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:verticalSpacing="0dp"
android:horizontalSpacing="0dp"
android:stretchMode="columnWidth"
android:numColumns="2"/>
</FrameLayout>

Here is the way I often do in my projects, IMO you can take a look and apply to your project, hope it helps!
#Override
protected void onCreate(Bundle savedInstanceState) {
...
mRequestQueue = Volley.newRequestQueue(this);
mProgressBar = (ProgressBar) findViewById(R.id.progressBar);
mProgressBar.setVisibility(View.VISIBLE);
JsonArrayRequest jsonArrayRequest = new JsonArrayRequest(Request.Method.GET, url, null, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
mProgressBar.setVisibility(View.INVISIBLE);
// do something...
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
mProgressBar.setVisibility(View.INVISIBLE);
// do something...
}
});
mRequestQueue.add(jsonArrayRequest);
...
}

you declare your progressbar
private ProgressDialog pDialog;
pDialog = new ProgressDialog(this);
// Showing progress dialog before making http request
pDialog.setMessage("Loading...");
pDialog.show();
you call you Volley request than when you get the response (either success or error event) you call the hidePDialog method
hidePDialog();
//method to hide progressbar
private void hidePDialog() {
if (pDialog != null) {
pDialog.dismiss();
pDialog = null;
}
}
don't forget to call the method in onDestroy() also

#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GridView newsListView = (GridView) findViewById(R.id.newsFeedList);
adapter = new NewsListAdapter(this, R.layout.adapter_news_list, newsListData, this);
layout = (LinearLayout) findViewById(R.id.progressbar_view);
newsListView.setAdapter(adapter);
newsListView.setOnItemClickListener(itemClicked);
EDANewsApp app = EDANewsApp.getInstance();
nextStart = 0;
updateListData(nextStart, 20);
}
private class Task extends AsyncTask<String, Integer, Boolean> {
private ProgressDialog dialog;
#Override
protected void onPreExecute() {
dialog.setMessage("Doing something, please wait.");
dialog.show();
layout.setVisibility(View.VISIBLE);
newsListView.setVisibility(View.GONE);
super.onPreExecute();
}
#Override
protected void onPostExecute(Boolean result) {
dialog.dismiss();
layout.setVisibility(View.GONE);
newsListView.setVisibility(View.VISIBLE);
adapter.notifyDataSetChanged();
super.onPostExecute(result);
}
#Override
protected Boolean doInBackground(String... params) {
stringValues.add("String 1");
stringValues.add("String 2");
stringValues.add("String 3");
stringValues.add("String 4");
stringValues.add("String 5");
try {
Thread.sleep(3000);
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
}
Hope this will help you.

Seems like duplicate of play youtube video in WebView and YouTube Video not playing in WebView - Android
To make it work via WebView, I used the following two steps (version 4.2.2/Nexus 4):
On shouldOverrideUrlLoading I added webview.setWebChromeClient(new WebChromeClient());
In AndroidManifest.xml for activity tag I added android:hardwareAccelerated="true"
AndroidManifest.xml should also contain Internet permission.
While exact steps with playing video via WebView can be specific to device and Android version, there are also other alternatives to WebView, like VideoView or using Youtube Android Player API.
EDIT1
As for pause and full screen, this is actually a second link I mentioned in the beginning. To make it easier, I am posting code that worked on my Nexus.
In activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<FrameLayout
android:id="#+id/fullscreen_custom_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#FF000000"/>
<LinearLayout
android:id="#+id/linearlayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<WebView
android:id="#+id/webView"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</LinearLayout>
</RelativeLayout>
In MainActivity class:

Adding webchrome client solves the issue,
web = (WebView) vi.findViewById(R.id.offer_webView1);
web.loadUrl(getResources().getString(R.string.videolink));
web.getSettings().setJavaScriptEnabled(true);
// web.getSettings().setDomStorageEnabled(true);
web.getSettings().setAllowContentAccess(true);
WebSettings webSettings = web.getSettings();
webSettings.setPluginState(WebSettings.PluginState.ON);
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);
web.canGoBack();
web.setWebChromeClient(new WebChromeClient() {});
