Android Studio multiple numbers with spinner selection

Android Studio multiple numbers with spinner selection - java

So I'm attempting to have a spinner where you select a currency to convert to from GBP, enter a value in GBP and convert to the selected currency from the spinner by pressing a button. The converted value will then appear in the textview below
Here is the following code I have in the Convert activity i'm using, the app is crashing upon trying to switch to this layout from the main menu, however it was working before i tried adding the multiplication code. Thanks in advance.
public class Convert extends AppCompatActivity {
final EditText currency_input = (EditText) findViewById(R.id.editText_currency_input);
final TextView answer = (TextView) findViewById(R.id.textView_convert_to);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.convert);
Spinner spinner_convert_from = (Spinner) findViewById(R.id.spinner_convert_from);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
R.array.currency_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner_convert_from.setAdapter(adapter);
}
private void USD() {
answer.setText(String.valueOf(Double.valueOf(String.valueOf(currency_input.getText()))*1.2798));
}
private void EUR() {
answer.setText(String.valueOf(Double.valueOf(String.valueOf(currency_input.getText()))*1.14502));
}
private void AUD() {
answer.setText(String.valueOf(Double.valueOf(String.valueOf(currency_input.getText()))*1.71911));
}
private void CAD() {
answer.setText(String.valueOf(Double.valueOf(String.valueOf(currency_input.getText()))*1.7226));
}
private void JPY() {
answer.setText(String.valueOf(Double.valueOf(String.valueOf(currency_input.getText()))*142.482));
}
private void CHF() {
answer.setText(String.valueOf(Double.valueOf(String.valueOf(currency_input.getText()))* 1.24662));
}
private void CNY() {
answer.setText(String.valueOf(Double.valueOf(String.valueOf(currency_input.getText()))* 8.7714));
}
private void KRW() {
answer.setText(String.valueOf(Double.valueOf(String.valueOf(currency_input.getText()))*1430.8));
}
private void SEK() {
answer.setText(String.valueOf(Double.valueOf(String.valueOf(currency_input.getText()))* 11.1187));
}
public class planOnClickListener implements AdapterView.OnItemSelectedListener {
#Override
public void onItemSelected(AdapterView<?> parent, View v, int pos,
long id) {
parent.getItemAtPosition(pos);
if (pos == 0) {
USD();
} else if (pos == 1) {
EUR();
} else if (pos == 2) {
AUD();
} else if (pos == 3) {

} else if (pos == 4) {

} else if (pos == 6) {

There are some common errors in your codes. I have updated your code.
Here is the working code:

super.onCreate(savedInstanceState);
setContentView(R.layout.convert);
// Views
currency_input = (EditText) findViewById(R.id.editText_currency_input);
answer = (TextView) findViewById(R.id.textView_convert_to);
// Default value
currency_input.setText("0.0");
Spinner spinner_convert_from = (Spinner) findViewById(R.id.spinner_convert_from);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
R.array.currency_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner_convert_from.setAdapter(adapter);
// Add item selected listener
spinner_convert_from.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View v, int pos,
long id) {
// Get input text
input = currency_input.getText().toString();
if (pos == 0) {
USD();
} else if (pos == 1) {
EUR();
} else if (pos == 2) {
AUD();
} else if (pos == 3) {

} else if (pos == 4) {

} else if (pos == 5) {
CHF();
} else if (pos == 6) {
CNY();
} else if (pos == 7) {
KRW();
} else if (pos == 8) {
SEK();
}
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
});
}
private void USD() {
answer.setText(String.valueOf(Double.valueOf(input)*1.2798));
}
private void EUR() {
answer.setText(String.valueOf(Double.valueOf(input)*1.14502));
}
private void AUD() {

Is it possible to set ViewPager inside a fragment class?

I have a Fragment class and an Activity class which is related to that fragment, ViewPager has been initialized inside the Activity of MizActivity
My question is it possible to move ViewPager initialization from Activity class to the Fragment class So that I have better control?
Thanks in advance

Yes, a Viewpager can be setup in a Fragment.
You just need to get the right FragmentManager when constructing it i.e use getChildFragmentManager() in mViewPager.setAdapter(new TvShowEpisodeDetailsAdapter(getSupportFragmentManager()));
From https://developer.android.com/guide/fragments/fragmentmanager
Access the FragmentManager
Accessing in an activity
Every FragmentActivity and subclasses thereof, such as
AppCompatActivity, have access to the FragmentManager through the
getSupportFragmentManager() method.
Accessing in a Fragment
Fragments are also capable of hosting one or more child fragments.
Inside a fragment, you can get a reference to the FragmentManager that

I have a navigation activity, where i also have a recycle view and a toolbar, to use the toolbar and the recycle view on this view, I created a separate XML layout like this:
<android.support.design.widget.CoordinatorLayout xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.afcosta.inesctec.pt.android.PlantFeed">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/emerald"
app:popupTheme="#style/AppTheme.PopupOverlay" />
<android.support.v7.widget.RecyclerView
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:id="#+id/recycleView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:backgroundTint="#f1c40f"
android:src="#android:drawable/ic_menu_camera" />
<include layout="#layout/content_plant_feed" />
</android.support.design.widget.CoordinatorLayout>
After this I included this layout on my main activity like this:
<android.support.v4.widget.DrawerLayout 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:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="#layout/app_bar_plant_feed"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_plant_feed"
app:menu="#menu/activity_plant_feed_drawer"
android:background="#color/white"/>
</android.support.v4.widget.DrawerLayout>
I am populating the recycler view with data of my database using also cardview, the thing is that with this approach (using include) my recycle view doesn't scroll, i have a lot of items but it always show just 4 of them.
my adapter:
public class PlantFeedAdapter extends RecyclerView.Adapter<PlantFeedAdapter.ViewHolder> {

Android BaseFragment class with multiple different fragment types

I created a base fragment class that handles setting the toolbar title, registering for when the fragment is attached, setting the menu icons and a few other things. My issue is that I've decided to use the PreferencesFragmentCompat for my settings fragment and I cant extend both my BaseFragment and androids PreferencesFragmentCompat. Using an interface here wouldn't help because my BaseFragment has a lot of functionality, and I don't want to duplicate it into each of my fragment classes. Normally to extend two classes, you just do it in two seperate files but because both already extend off Androids Fragment class, I dont see how this is possible. Is there a better way of doing this?
BaseFragment:
public abstract class BaseFragment extends Fragment {
protected View rootView;
protected AppSettings settings;
protected LayoutInflater inflater;
public static void startFragment(Activity activity, BaseFragment newFragment) {
FragmentManager fragManager = ((AppCompatActivity) activity).getSupportFragmentManager();
BaseFragment currentFragment = (BaseFragment) fragManager.findFragmentById(R.id.fragment_container);
// Start the transactions
FragmentTransaction transaction = fragManager.beginTransaction();
transaction.replace(R.id.fragment_container, newFragment);
// If there is already a fragment then we want it on the backstack
if (currentFragment != null) {
transaction.addToBackStack(null);
}
// Show it
transaction.commit();

This is a nice example, where you should apply Joshua Bloch's "Favor composition over inheritance" idiom.
You can delegate all the logic that you have applied to BaseFragment to some class FragmentHelper:
public class FragmentHelper {
private final Fragment fragment;
public FragmentHelper(Fragment fragment) {
this.fragment = fragment;
}
public void create(Bundle bundle) {
// `BaseFragment`'s code goes here
}
public void resume() {
// `BaseFragment`'s code goes here
}
...
}
Now in your BaseFragment:
public class BaseFragment {
private FragmentHelper fragmentHelper;
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
fragmentHelper = new FragmentHelper(this);
fragmentHelper.create(savedInstanceState);
}
#Override
public void onResume() {
fragmentHelper.resume();
}
}
And the same this should be applied to the class that is extending PreferenceFragment.
Thus, you'd evade from code duplication.

Custom SwitchPreference not saving value

When I access the PreferenceScreen, I notice that my custom switch is off. Then I turn it on and restart the app. I went back to the PreferenceScreen and the switch went back off. This doesn't happen when I use the default SwitchPreference. I am able to customize the SwitchPreference the way I want it to be, so the only problem is the switch value not saving. I have four files related to a customize SwitchPreference and all of the Preferences are placed in an extension of a PreferenceFragment
SettingsFragment.java

public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

You're never actually setting or saving the state of the switch. You need to override onBindView to set the initial state of the view, and attach a checked change listener to the Switch (R.id.switch_pref) to listen for changes and persist them into SharedPreferences (you can call persistBoolean to do that).
