Mapbox not Working With Fragments and bottom navigation
I get a blank page when i run the app , i am using bottom navigation bar and inside the fragment i run the mapbox code , i am trying to add Mapbox view inside the fragment .. i tried to implement the map box inside onViewCreated() but it doesn't work either.

public class TrackingFragment extends Fragment implements OnMapReadyCallback, PermissionsListener {
private PermissionsManager permissionsManager;
private MapboxMap map;
private MapView mapView;
public TrackingFragment() {
// Required empty public constructor

I want to know how to implement AdMob rewarded video ads in a list view?
I'm using the source code from here
and I want to use it in this class StickerPackDetailsActivity.java
and the layout is gonna like this
![layout][1]
I want to lock add to WhatsApp and unlock it by watching video reward.
but this stickerdetails showed from listview from
![here][2]
so, how to implement video reward ads only in 1 specified item of the listview not all of them?
public class MainActivity extends AppCompatActivity implements RewardedVideoAdListener {
private RewardedVideoAd mRewardedVideoAd;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MobileAds.initialize(this,"ca-app-pub111111111");
mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);
listitem.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
loadRewardedVideoAd();
}
});
}
private void loadRewardedVideoAd() {
mRewardedVideoAd.loadAd("ca-app-pub-",
new AdRequest.Builder().build());
}
#Override
public void onRewardedVideoAdLoaded() {
}
#Override
public void onRewardedVideoAdOpened() {
}
#Override
public void onRewardedVideoStarted() {
}
#Override
public void onRewardedVideoAdClosed() {
loadRewardedVideoAd();
}
#Override
public void onRewarded(RewardItem rewardItem) {
}
#Override
public void onRewardedVideoAdLeftApplication() {
}
#Override
public void onRewardedVideoAdFailedToLoad(int i) {
}
#Override
public void onRewardedVideoCompleted() {
}
#Override
protected void onPause() {
mRewardedVideoAd.pause(this);
super.onPause();
}
#Override
protected void onResume() {
mRewardedVideoAd.resume(this);
super.onResume();
}
}
I am receiving java.lang.NullPointerException, although I have binded the element correctly.
Tried to check the ID of the element, it matches, but still I receive the same exception.
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Text to Speech
tts = new TextToSpeech(this, this);
speakButton = findViewById(R.id.speakButton);
speechText = findViewById(R.id.speechText);
speakButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
speakOut();
}
});
// End
loadFragment(new HomeFragment());
BottomNavigationView navigation = findViewById(R.id.navigation);
navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
}
TranslatorFragment.java
public class TranslatorFragment extends Fragment {
public Button speakButton;
public TranslatorFragment(){
//Empty Constructor
}
#Override
public View onCreateView(#NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.translator_fragment, container, false);
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
speakButton = view.findViewById(R.id.speakButton);
}
}
It should be running fine, But I am receiving the java.lang.NullPointerException
You button code should be declared in you fragment not in you activity as the button is in your fragment.xml. As you are accessing the button in onCreate method of the activity it will give nullpointer exception because you fragment's view is not yet rendered.The best practice is to access the view in onViewCreated function of your fragment.
MainActivity.java
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
loadFragment(new HomeFragment());
BottomNavigationView navigation = findViewById(R.id.navigation);
navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
}
TranslatorFragment.java
public class TranslatorFragment extends Fragment {
public Button speakButton;
public TranslatorFragment(){
//Empty Constructor
}
#Override
public View onCreateView(#NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.translator_fragment, container, false);
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
//Text to Speech
tts = new TextToSpeech(getActivity(), this);
speakButton = findViewById(R.id.speakButton);
speechText = findViewById(R.id.speechText);
speakButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
speakOut();
}
});
// End
}
void speakOut(){
}
The solution is to implement TextToSpeech.OnInitListener in the project and make the public variables to be private.
public class TranslatorFragment extends Fragment implements TextToSpeech.OnInitListener{
private Button speakButton; // public Button speakButton;
private TextToSpeech tts;
private EditText speechText; // public EditText speechText;
public TranslatorFragment(){
//Empty Constructor
}
#Override
public View onCreateView(#NonNull LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.translator_fragment, container, false);
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
tts = new TextToSpeech(getActivity(), this);
speakButton = view.findViewById(R.id.speakButton);
speechText = view.findViewById(R.id.speechText);
speakButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
speakOut();
}
});
}
private void speakOut(){
String text = speechText.getText().toString();
tts.speak(text, TextToSpeech.QUEUE_FLUSH, null);
}
public void onInit(int status){
if(status == TextToSpeech.SUCCESS){
int result = tts.setLanguage(Locale.getDefault());
if(result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED){
Toast.makeText(getActivity(), "Language not supported!", Toast.LENGTH_SHORT).show();
} else {
speakButton.setEnabled(true);
speakOut();
}
}
else
{
Toast.makeText(getActivity(), "Initilization failed!", Toast.LENGTH_SHORT).show();
}
}
public void onDestroy() {
if(tts != null){
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
}
While debugging on USB I just wanted to expand WebView to fullscreen. Unfortunately, white screen appeared and nothing after it. I really do not know what to do. I made CustomView and everything seemed fine. Here is my code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
filmkey = "<iframe width=\"96%\" height=\"96%\" src=\"https://www.youtube.com/embed/EtMOgsWEAmQ\" frameborder=\"0\" allowfullscreen></iframe>";
screen=(WebView)findViewById(R.id.webView);
screen.getSettings().setJavaScriptEnabled(true);
String myvideokey = filmkey;
screen.loadData(myvideokey, "text/html", "utf-8");
screen.setWebChromeClient(new WebChromeClient(){
#Override
public void onShowCustomView(View view, CustomViewCallback callback) {
super.onShowCustomView(view, callback);
}
#Override
public void onHideCustomView() {
super.onHideCustomView();
}
});
}
try the following Code. In this on full screen i created a View which will become full Screen.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {
screen.restoreState(savedInstanceState);
}
setContentView(R.layout.activity_support);
filmkey = "<iframe width=\"96%\" height=\"96%\" src=\"https://www.youtube.com/embed/EtMOgsWEAmQ\" frameborder=\"0\" allowfullscreen></iframe>";
screen=(WebView)findViewById(R.id.webview);
screen.getSettings().setJavaScriptEnabled(true);
String myvideokey = filmkey;
screen.loadData(myvideokey, "text/html", "utf-8");
CustomWebChromeClient custom = new CustomWebChromeClient();
screen.setWebChromeClient(custom);
}
and the custom WebChromeClient is
class `CustomWebChromeClient` extends WebChromeClient{
#Override
public void onShowCustomView(View view, final CustomViewCallback callback) {
super.onShowCustomView(view, callback);
Dialog dialog = new Dialog(SupportActivity.this, android.R.style.Theme_Black_NoTitleBar_Fullscreen);
view.setBackgroundColor(Color.TRANSPARENT);
dialog.setContentView(view);
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
#Override
public void onDismiss(DialogInterface dialog) {
callback.onCustomViewHidden();
}
});
dialog.show();
}
#Override
public void onHideCustomView() {
super.onHideCustomView();
}
}
and also make sure you use all these methods in the activity to handle with the data in webView.
#Override
protected void onResume() {
super.onResume();
screen.onResume();
}
#Override
protected void onPause() {
super.onPause();
screen.onPause();
}
#Override
protected void onStop() {
super.onStop();
screen.stopLoading();
}
#Override
protected void onDestroy() {
super.onDestroy();
screen.destroy();
}
#Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
screen.saveState(outState);
}
I hope it helps.
I have an AppCompatPreferenceActivity.java. But it shows an error in this
public class SettingsActivity extends AppCompatPreferenceActivity
It says it couldn't resolve 'AppCompatPreferenceActivity'.
And it seems like I am the only one with this problem. Any idea?
Error:(21, 39) error: cannot find symbol class AppCompatPreferenceActivity
AppCompatPreferenceActivity does not existing in google support libary,
you should create a class with same name and use this source:
public abstract class AppCompatPreferenceActivity extends PreferenceActivity {
private AppCompatDelegate mDelegate;
#Override
protected void onCreate(Bundle savedInstanceState) {
getDelegate().installViewFactory();
getDelegate().onCreate(savedInstanceState);
super.onCreate(savedInstanceState);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
getDelegate().onPostCreate(savedInstanceState);
}
public ActionBar getSupportActionBar() {
return getDelegate().getSupportActionBar();
}
public void setSupportActionBar(#Nullable Toolbar toolbar) {
getDelegate().setSupportActionBar(toolbar);
}
#Override
public MenuInflater getMenuInflater() {
return getDelegate().getMenuInflater();
}
#Override
public void setContentView(#LayoutRes int layoutResID) {
getDelegate().setContentView(layoutResID);
}
#Override
public void setContentView(View view) {
getDelegate().setContentView(view);
}
#Override
public void setContentView(View view, ViewGroup.LayoutParams params) {
getDelegate().setContentView(view, params);
}
#Override
public void addContentView(View view, ViewGroup.LayoutParams params) {
getDelegate().addContentView(view, params);
}
#Override
protected void onPostResume() {
super.onPostResume();
getDelegate().onPostResume();
}
#Override
protected void onTitleChanged(CharSequence title, int color) {
super.onTitleChanged(title, color);
getDelegate().setTitle(title);
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
getDelegate().onConfigurationChanged(newConfig);
}
#Override
protected void onStop() {
super.onStop();
getDelegate().onStop();
}
#Override
protected void onDestroy() {
super.onDestroy();
getDelegate().onDestroy();
}
public void invalidateOptionsMenu() {
getDelegate().invalidateOptionsMenu();
}
private AppCompatDelegate getDelegate() {
if (mDelegate == null) {
mDelegate = AppCompatDelegate.create(this, null);
}
return mDelegate;
}
}
How and Where do I set view contents to be displayed for persons who has successfully been authenticated using Facebook SDK?
After the persons has logged In, I want to display a User profile view.
I have tried to Instansiate a new fragment like the code below, but that don't work. The text "Fish" Is not displayed.
public class LoginFragment extends Fragment {
private CallbackManager mCallbackManager;
private static final String TAG = "Facebook";
private LoginButton login;
private FacebookCallback<LoginResult> mCallback = new FacebookCallback<LoginResult>() {
#Override
public void onSuccess(LoginResult loginResult) {
Log.i(TAG, " logged in...");
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile(); //Access the profile who Is the person login in
if(profile != null) {
FragmentManager fm = getFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.fragmentContainer);
if(fragment == null) {
fragment = new LoggedInFragment();
fm.beginTransaction().add(R.id.fragmentContainer, fragment).commit();
}
}
}
#Override
public void onCancel() {
}
#Override
public void onError(FacebookException e) {
Log.i(TAG, " Error");
}
};
public LoginFragment() {
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
mCallbackManager = CallbackManager.Factory.create();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.login, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
LoginButton loginButton = (LoginButton) view.findViewById(R.id.login_button);
//Ask the use for permission to access friends
loginButton.setReadPermissions("user_friends");
//Because we work with fragments
loginButton.setFragment(this);
loginButton.registerCallback(mCallbackManager, mCallback);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
mCallbackManager.onActivityResult(requestCode, resultCode, data);
}
}
Here IS fragement that the user should see when he/she Is logged In:
package com.waddapp.bryan.waddapp;
public class LoggedInFragment extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getActivity().getApplicationContext());
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.logged_in, container, false);
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
TextView mTextDetails = (TextView)view.findViewById(R.id.text_details);
mTextDetails.setText("FISH");
}
public LoggedInFragment() {
}
}
Anyone who can explain how acomplish this?
