So I was able to make a Spinner work in a single Activity, but when I transferred the code to a Fragment it obviously didn't work.
I think the Error was from the Instatiation of Spinner.
Use this one for your TextView and Spinner.
<Spinner
android:id="#+id/spinnerComplaintType"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_marginTop="54dp"
android:layout_toRightOf="#+id/buttonSend"
android:textColor="#000000" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/textView3"
android:layout_alignTop="#+id/spinnerComplaintType"
android:layout_marginTop="17dp"
android:text="File Complaint"
android:textAppearance="?android:attr/textAppearanceLarge" />
Also Change
android.R.layout.simple_spinner_item
instead of
android.R.layout.simple_list_item_1
in your Array Adapter.
UPDATE:
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(getActivity(),
R.array.complaintType, android.R.layout.simple_spinner_item);

At least one of the drawables referenced in your second XML file is too big.
Check the following drawables and resize them:
sheep
title
list_fluid
PNGs generally don't need to be very large. Keep them below 1600x1600 if you can, preferably 800x800.

Thank you in advance.
so, I'm getting an error after trying to load a tab in a Master/Flow layout. The tab that makes the app crash is a calculator with two images and a background image.
Here's the error:

And this is where it is telling me the error is (ItemDetailFragment.java:66):
it is "rootView = inflater.inflate(R.layout.price_calculator, container, false);"
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_item_detail, container, false);
if (mItem !=null) {
if (mItem.id.equals("1")) {
rootView = inflater.inflate(R.layout.welcome_page, container, false);
} else if (mItem.id.equals("2")) {
rootView = inflater.inflate(R.layout.price_calculator, container, false);
} else if (mItem.id.equals("3")) {
((WebView) rootView.findViewById(R.id.item_Detail)).loadUrl(mItem.item_url);
}
}
return rootView;
}

I tried to implement tabs into my app and followed this tutorial:
http://android-er.blogspot.de/2012/06/create-actionbar-in-tab-navigation-mode.html
But now i have the problem that my TabListener does not take the parameters from my tabs.
tab1 class:
package com.example.MainActivity;
import android.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.example.MainActivity.R;
public class Tab1 extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View myFragmentView = inflater.inflate(R.layout.fragment_a, container, false);
return myFragmentView;
}
}
and this is my TabListener:
public class TabListener <T extends Fragment> implements ActionBar.TabListener{
private final Activity myActivity;
private final String myTag;
private final Class myClass;
public TabListener(Activity activity, String tag, Class<T> cls) {
myActivity = activity;
myTag = tag;
myClass = cls;
}
#Override
public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) {
Fragment myFragment = myActivity.getFragmentManager().findFragmentByTag(myTag);
// Check if the fragment is already initialized
if (myFragment == null) {
// If not, instantiate and add it to the activity
myFragment = Fragment.instantiate(myActivity, myClass.getName());
ft.add(android.R.id.content, myFragment, myTag);
} else {
// If it exists, simply attach it in order to show it
ft.attach(myFragment);
}
}
#Override
public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) {
Fragment myFragment = myActivity.getFragmentManager().findFragmentByTag(myTag);
if (myFragment != null) {
// Detach the fragment, because another one is being attached
ft.detach(myFragment);
}
}
#Override
public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) {
// TODO Auto-generated method stub
}
}
MainActivity:
public class MyActivity extends Activity {
private String string1 = "gahwareawbad password gagaw";
public String datum = new String("");
//STUNDENPLAN-VARIABLEN
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
ActionBar.Tab tabA = actionBar.newTab();
tabA.setText("Tab A");
tabA.setTabListener(new TabListener<Tab1>(this, "Tag A", Tab1.class));
actionBar.addTab(tabA);
Tab tabB = actionBar.newTab();
tabB.setText("Tab B");
tabB.setTabListener(new TabListener<Tab2>(this, "Tag B", Tab2.class));
actionBar.addTab(tabB);
Tab tabC = actionBar.newTab();
tabC.setText("Tab C");
tabC.setTabListener(new TabListener<Tab3>(this, "Tag C", Tab3.class));
actionBar.addTab(tabC);
if (savedInstanceState != null) {
int savedIndex = savedInstanceState.getInt("SAVED_INDEX");
getActionBar().setSelectedNavigationItem(savedIndex);
}
// quellcode = (TextView) findViewById(com.example.MainActivity.R.id.TextView01);
geschichte = (TextView) findViewById(com.example.MainActivity.R.id.geschichte);
datum1 = (TextView) findViewById(com.example.MainActivity.R.id.datum1);
}
#Override
protected void onSaveInstanceState(Bundle outState) {
// TODO Auto-generated method stub
super.onSaveInstanceState(outState);
outState.putInt("SAVED_INDEX", getActionBar().getSelectedNavigationIndex());
}
}

Issue with the Import in MainActivity
change this
import android.app.ActionBar.TabListener;
to
import com.example.MainActivity.TabListener
or change your custom TabListener class name.
I have been trying to use the addTextChangedListener for three days, The log says that it is caused by java.lang.NullPointerException. When I comment the addTextChangedListener block the program runs fine.
import android.support.v7.app.ActionBarActivity;

public class calc extends ActionBarActivity {
EditText text;
private TextView textout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_calc);
text = (EditText) findViewById(R.id.fs);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment())
.commit();
}
text.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence charSequence, int i, int i2, int i3) {

#Override

});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.calc, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long

int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**

public static class PlaceholderFragment extends Fragment {
public PlaceholderFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_calc, container, false);
return rootView;
}
}
}
And here we have the log.

The log says that the problem is found in onCreate and it is caused by a java.lang.NullPointerException.
Any thoughts?
Thanks for everything!

I have also tried to debbug it in my phone, I get the same problem.
I'm not entirely sure why you app compiles in the first place, but the problem initially was that your findViewById() method was returning null because it couldn't find a view matching your ID.
Your current issues include:
- Your text object is declared as TextView while it should be an
EditText
- In your layout, your view with id R.id.fs is a TextView when it should be an EditText.
try change TextView text; to EditText text;
I found the problem.
My layout was on fragment_main, sorry!
Thanks for the help!!
