I need to create a Stepper in my application that I got the library on Github https://github.com/shivasurya/materialsteppers
I managed to implement the application, however I want to put a Toolbar to inflate a menu and have the back button in it, but I am not able to put in the application. Follows the codes:
Xml screen 1:
<?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"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbarSessao2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:minHeight="?attr/actionBarSize"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/scrollView"
style="@style/FundoAPP"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/toolbarSessao2"
android:layout_gravity="right">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:weightSum="1">
<TextView
style="@style/titleHints"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/hint_sessao_1" />
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingLeft="?android:attr/listPreferredItemPaddingLeft"
android:paddingRight="?android:attr/listPreferredItemPaddingRight"
android:paddingTop="24dp">
<EditText
android:id="@+id/JN_04_01"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:hint="@string/hintHora"
android:textColorHint="#ffa3a3a3" />
</android.support.design.widget.TextInputLayout>
<View style="@style/Divider" />
<TextView
android:id="@+id/textView4"
style="@style/Textos"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:paddingLeft="?android:attr/listPreferredItemPaddingLeft"
android:paddingRight="?android:attr/listPreferredItemPaddingRight"
android:paddingTop="24dp"
android:text="@string/Repet" />
</LinearLayout>
</ScrollView>
</RelativeLayout>
Screen 2 is similar to the one above...
This is the Fragment of this screen above:
public class sessao_fragment1 extends stepperFragment implements View.OnClickListener{
public sessao_fragment1(){
}
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
return inflater.inflate(
R.layout.sessao1, container, false);
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_jn_04_sessao, menu);
}
@Override
public boolean onNextButtonHandler() {
return true;
}
@Override
public void onClick(View v) {
}
}
The second screen is also the same...
And that’s the screen that controls Stepper:
public class stepper_sessao extends progressMobileStepper implements View.OnClickListener{
List<Class> stepperFragmentList = new ArrayList<>();
@Override
public List<Class> init() {
stepperFragmentList.add(sessao_fragment1.class);
stepperFragmentList.add(sessao_fragment2.class);
return stepperFragmentList;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbarSessao2);
toolbar.setTitle(R.string.title_activity_inserir_programacao);
toolbar.setTitleTextColor(getResources().getColor(R.color.colorTextButton));
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
// Set an OnMenuItemClickListener to handle menu item clicks
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
// Handle the menu item
switch (item.getItemId()) {
case R.id.manutencao_sessoes:
startActivity(new Intent(getApplicationContext(), jn_14_manutencao_sessao.class));
break;
case R.id.cad_Remedio:
startActivity(new Intent(getApplicationContext(), jn_03_remedio.class));
break;
case R.id.salvarSessao:
//SALVAR();
break;
}
return true;
}
});
toolbar.inflateMenu(R.menu.menu_jn_04_sessao);
}
@Override
public View onCreateView(View parent, String name, Context context, AttributeSet attrs) {
return super.onCreateView(parent, name, context, attrs);
}
@Override
public View onCreateView(String name, Context context, AttributeSet attrs) {
return super.onCreateView(name, context, attrs);
}
@Override
public void onStepperCompleted() {
showCompletedDialog();
}
protected void showCompletedDialog(){
android.support.v7.app.AlertDialog.Builder alertDialogBuilder = new android.support.v7.app.AlertDialog.Builder(
stepper_sessao.this);
// set title
/*alertDialogBuilder.setTitle("Hooray");
alertDialogBuilder
.setMessage("We've completed the stepper")
.setCancelable(true)
.setPositiveButton("Yes",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
}
});
*/
// create alert dialog
android.support.v7.app.AlertDialog alertDialog = alertDialogBuilder.create();
// show it
alertDialog.show();
//finish();
}
@Override
protected void onDestroy() {
super.onDestroy();
}
}The Toolbar I put this commented on this last screen, but it was not correct... if you can help!
that’s the mistake:
02-14 23:05:48.443 1354-1354/com.housepharm E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.housepharm, PID: 1354
java.lang.RuntimeException: Unable to start activity ComponentInfo{com.housepharm/com.housepharm.Visao.Tela.stepper_sessao}: java.lang.NullPointerException
From what I understand of this library, the simplest way is to have an Activity that configure and control the
Stepper, I don’t know if that’s what’s going on. But Toolbar should be set up inActivityand not in Fragment. But it seems to me that thestepper_sessaois aFragment. You are using a Fragment to control theStepper?– Wakim
So, I looked at his code, the only thing he does in Mainactivity is to extend the progressiMobileStepper, however, his project has Darkactionbar style and I’m using Theme.AppCompat.Light.Noactionbar; I tried too, after you spoke, put the Toolbar inside onCreate instead of onCreateView, but it gave java.lang.Nullpointerexception error after creating the object

Where generates the error? Could change the question with the code that generated the error?

I completed the code as requested
