i have a tabbed activity.
When i switch from tab1 to tab2 or 3,the app runs smooth.
Again i switch to tab1 and then switch to any other tab,the app crashes.
Tabbed activity java code
public class MainActivity extends AppCompatActivity {
ViewPager vp;
TabLayout tab;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
vp= (ViewPager) findViewById(R.id.viewpager);
tab= (TabLayout) findViewById(R.id.tab);
vp.setAdapter(new CustomAdapter(getSupportFragmentManager(),MainActivity.this));
tab.setupWithViewPager(vp);
tab.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
vp.setCurrentItem(tab.getPosition());
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
private class CustomAdapter extends FragmentPagerAdapter
{
private String fragments[]={"District","NearBy","Search"};
public CustomAdapter(FragmentManager supportFragmentManager, Context applicationContext)
{
super(supportFragmentManager);
}
#Override
public Fragment getItem(int position)
{
switch (position)
{
case 0:
return new MqmDList();
case 1:
return new MqmLList();
case 2:
return new Mqm_MList();
default:
return null;
}
}
#Override
public int getCount() {
return fragments.length;
}
#Override
public CharSequence getPageTitle(int position) {
return fragments[position];
}
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_BACK
&& event.getRepeatCount() == 0) {
Intent homeIntent = new Intent(Intent.ACTION_MAIN);
homeIntent.addCategory( Intent.CATEGORY_HOME );
homeIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(homeIntent);
}
return super.onKeyDown(keyCode, event);
}

You have to remove map fragment when changing tab. It worked for me ;)
#Override public void onDestroyView() {
super.onDestroyView();
FragmentManager fm = getActivity().getSupportFragmentManager();
Fragment fragment = (fm.findFragmentById(R.id.mapd));
FragmentTransaction ft = fm.beginTransaction();
ft.remove(fragment);
ft.commit();
}

I am a beginner in android development and I have encountered some difficulty in running my app in the simulator. I am following chapter 12 of the head first textbook to design an app with tab navigation. It has four fragments and I am using the fragment pager adapter to navigate through the app. When I run the app in the simulator it is crashed with the error message "app has stopped working". My code for the main activity is as follows:
package com.hfad.bitsandpizzas;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import androidx.appcompat.widget.ShareActionProvider;
import androidx.appcompat.widget.Toolbar;
import androidx.core.view.MenuItemCompat;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentManager;
import androidx.fragment.app.FragmentPagerAdapter;
import androidx.viewpager.widget.ViewPager;
public class MainActivity extends AppCompatActivity {
private ShareActionProvider shareActionProvider;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
SectionsPagerAdapter pagerAdapter =
new SectionsPagerAdapter(getSupportFragmentManager());
ViewPager pager = (ViewPager) findViewById(R.id.pager);
pager.setAdapter(pagerAdapter);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
MenuItem menuItem = menu.findItem(R.id.action_share);
shareActionProvider =
(ShareActionProvider) MenuItemCompat.getActionProvider(menuItem);
setShareActionIntent("Want to join me for pizza?");
return super.onCreateOptionsMenu(menu);
}
private void setShareActionIntent(String text) {
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_TEXT, text);
shareActionProvider.setShareIntent(intent);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_create_order:
Intent intent = new Intent(this, OrderActivity.class);
startActivity(intent);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
private class SectionsPagerAdapter extends FragmentPagerAdapter {
public SectionsPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public int getCount() {
return 4;
}
#Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return new TopFragment();
case 1:
return new PizzaFragment();
case 2:
return new PastaFragment();
case 3:
return new StoresFragment();
}
return null;
}
}
}
the error message from the logcat is this

You are useing the Androidx support Library ,but in your xml layout ,you are useing the android.support.v4.view.ViewPager , you must change the ViewPager to Androidx support Library，use: androidx.viewpager.widget.ViewPager instead.

setPreferencesFromResource(R.xml.preferences, rootKey);
}
}
I solve this issue by changing theme preference Theme.Leanback
On your manifest file :
<activity android:name=".ui.setting.YourSettingPrefActivity"
android:exported="true"
android:theme="#style/Theme.Pref.LeanbackPreferences"/>
And here on styles.xml
<style name="Theme.Pref.LeanbackPreferences" parent="Theme.Leanback">
<item name="preferenceTheme">#style/PreferenceThemeOverlay.v14.Leanback</item>
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:backgroundDimEnabled">true</item>
<item name="android:colorPrimary">#color/fastlane_background</item>
</style>
I have a preference fragment with the following files
preference.xml
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<EditTextPreference
android:defaultValue="0000"
android:key="#string/pin"
android:summary="Set Pin for Notes"
android:title="Password" />
</PreferenceScreen>
Preference Activity
public class PreferenceActivity extends AppCompatActivity {
#BindView(R.id.toolbar_settings)
Toolbar toolbarSettings;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_settings);
ButterKnife.bind(this);
setSupportActionBar(toolbarSettings);
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
}
}
}
and finally
Preference Fragment
public class PreferenceFragment extends PreferenceFragmentCompat {
#Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
addPreferencesFromResource(R.xml.preference);
}
}
But here when the addPreferencesFromResources is called, I am getting a runtime exception.
Here is the log stack

I had a switch preference before the edit text preference and that worked fine. Once i replaced the switch preference with edit text preference, this error is thrown.
How do I fix this?
Can you try the code below?
strings.xml
<string name="pin_default_value">0000</string>
preference.xml
<EditTextPreference
android:defaultValue="#string/pin_default_value"
android:key="#string/pin"
android:summary="Set Pin for Notes"
android:title="Password" />
Android is trying to set default value but it is reading 0000 as an Integer and not as a String Main reason is that android:defaultValue is not directly handled as String. This way, to avoid this int to Stringconversion error, you must explicit use a String value (by using some string from strings.xml.
Note
You may need to clear your app data since that wrong default value may be stored in cached files already.

What is a NullPointerException, and how do I fix it?

Closed 1 year ago.
I have a fragment where I want to display values from a List, so I get it like this in Activity Recipe Detail
IngredientsFragment ingredientsFrag = new IngredientsFragment();
ingredientsFrag.setPosition(position);
ingredientsFrag.setRecipes(MainActivity.receipes);
getSupportFragmentManager().beginTransaction()
.replace(R.id.FRGingredients, ingredientsFrag)
.commit();
The main thing up there to take note of is the SetRecipes() Method, I am passing in a List, it is a static List in the MainActivity class.
In the Ingredients fragment I have this in Ingredient Fragment:
public class IngredientsFragment extends Fragment {
int position;
List<Recipe> mRecipes;
String test;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.frag_recipe_ingredients, container, false);
TextView ingredients = rootView.findViewById(R.id.ingredientsTxt);
ingredients.setText(String.valueOf(mRecipes.get(0).getName()));
return rootView;
}
public void setPosition(int position) {
this.position = position;
}
public void setRecipes(List<Recipe> recipes) {
test = String.valueOf(recipes.get(0).getName());
mRecipes = recipes;
}
}
When I run this code this is what I get:

So it does not recognize the variable mRecipes, but what puzzles me is that when I use the variable test it woks, which means that the list actually is passed down in the method, but anytime I try accessing it in onCreateView, it tell me that null error. Though I can access test if I change it to
ingredients.setText(test);
It works when I do it like that, which means OnCreateView is seeing variable test it also means that the List passed into the method initially was not null.
That's not how you pass an array or any other variable for that matter to a fragment from an activity. You have to pass a bundle holding your array to your fragment with:
Bundle bundle = new Bundle();
bundle.putStringArrayList("edttext", arraylist);
Fragmentclass fragobj = new Fragmentclass();
fragobj.setArguments(bundle);
IngredientsFragment ingredientsFrag = new IngredientsFragment();
ingredientsFrag.setArguments(bundle);
getSupportFragmentManager().beginTransaction()
.replace(R.id.FRGingredients, ingredientsFrag)
.commit();
Make sure your POJO Recipe implements Parcelable.

at com.lemuel.lemubit.bakenow.Fragments.IngredientsFragment.onCreateView(IngredientsFragment.java:34)
the exception is clear NullPointerException while accessing the list.
you have to put your list into Bundle and set it as arguments to your fragment ..
then in the fragment class you can get this bundle from your fragment in the onCreateView method.
Couple moths ago i testing this app on Android N and all will work correctly, but now i have error. Now i'am using MapFragment and have this error:

also try to change AppCompatActivity to FragmentActivity. Before that i'am using SupportMapFragment and have same error. What wrong?
I also experience the same(which was no problem previously). Workaround is to add following flag to your MapActivity in your AndroidManifest.xml file
android:hardwareAccelerated="true"
