Setting ListView

I am having trouble with listview and spinners. I am using a list view to display items and using a spinner to filter between categories and a button to refresh the view. My problem is that after selecting a different category it does not change the listView and reverts the spinner to the original category. I have tried using .clear() and an onClickListener() but my problem persists. Is there a way to make the spinner change the items in the listView after clicking the button?

}
}

Would suggest two things:
Relocate your spinner setup from 'menuViewingMethod()' to 'onCreateView()'. This is probably the cause of your spinner resetting to 0 every time the 'menuViewingMethod()' is triggered.
In 'menuViewingMethod()', make 'menuArrayList' and 'arrayAdapter' class variable and reload the list with new contents instead.
String[] salads = new String[]{"Salad1", "Salad 2", "Salad 3"};
menuArrayList.clear();
menuArrayList.addAll(Arrays.asList(salads));
arrayAdapter.notifyDataSetChanged();

how to display listview items, when a user enter some number in textbox?

how to display listview items in android, when a user enter some number in edittext and click on a button to display the specified number of list items on the next activity ?
I have one EditText and a Button on MainActivity1 and a ListView and TextView on MainActivity2. TextView is just for letting me know tht value is passing on next screen.
MainActivity.java
package com.populatelist;
import android.support.v7.app.ActionBarActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final EditText edt = (EditText)findViewById(R.id.editText1);
Button btn = (Button)findViewById(R.id.button1);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent myin = new Intent(MainActivity.this,MainActivity2.class);
myin.putExtra("textbox", edt.getText().toString());
startActivity(myin);
}
});
}
}
MainActivity2.java
package com.populatelist;
import android.support.v7.app.ActionBarActivity;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.ListView;
import android.widget.TextView;
public class MainActivity2 extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_activity2);
TextView tv = (TextView)findViewById(R.id.textView1);
Intent myin2 = getIntent();
String str = myin2.getStringExtra("textbox");
tv.setText(str);
final ListView lv = (ListView) findViewById(R.id.listView1);
String[] arrStr = new String[] {
"Hello World",
"Hello India",
"Hello Rajasthan",
"Hello Jodhpur",
"Hello Mujeeb"
};
final List<String> hello_list = new ArrayList<String>(Arrays.asList(arrStr));
final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, hello_list);
int n = Integer.parseInt(str);
lv.setAdapter(arrayAdapter);
}
}

You can simply add the coming value at last of your string array like
String[] arrStr = new String[] {
"Hello World",
"Hello India",
"Hello Rajasthan",
"Hello Jodhpur",
"Hello Mujeeb",
str
};
It will show your input value to last position of your listview.
And if you want to add new items and show old as well then you have to pass whole string array to previous activity and add new value to last position, pass it when start next activity. By using this you can see all data on listview.

Whenever you get value in second activity create a new array "b" with required no of values.
String str = myin2.getStringExtra("textbox");
int noOfNames = Integer.parseInt(str);
String[] b = new String[StringnoOfNames];
Then copy the items from the original array
b = Arrays.copyOf(arrStr, noOfNames);
final List<String> hello_list = new ArrayList<String>(Arrays.asList(b));

First, validate if your EditText isn't null, here your app may crash
if (edt.getText().length() > 0) {
Intent myin = new Intent(MainActivity.this,MainActivity2.class);
myin.putExtra("textbox", Integer.parseInt(edt.getText().toString()));
startActivity(myin);
}
Then handle your intent
ListView lv = (ListView) findViewById(R.id.listview1);
ArrayAdapter<String> arrayAdapter = null;
int number = intent.getIntExtra("textbox", 0);
switch (number) {
case 0:
arrayAdapter = new ArrayAdapter<String>(context, android.R.layout.simple_list_item_1, arrStr);
lv.setAdapter(arrayAdapter);
arrayAdapter.notifyDataSetChanged();
break;
case 1:
arrayAdapter = new ArrayAdapter<String>(context, android.R.layout.simple_list_item_1, AnotherSourceArray);
lv.setAdapter(arrayAdapter);
arrayAdapter.notifyDataSetChanged();
break;
case 2:
arrayAdapter = new ArrayAdapter<String>(context, android.R.layout.simple_list_item_1, AnotherSourceArray);
lv.setAdapter(arrayAdapter);
arrayAdapter.notifyDataSetChanged();
break;
...
default:
break;
}
Note - this is just sample. You can resolve this on many another ways. Each switch case may contain another data to display. Using default layouts for listviews may be frustrating, better way is to create custom class which extends ArrayAdapter<String>

Unable to pass intent in custom array adapter

I am unable to pass an intent in this case. Nothing is displayed on the screen or Logs from the movie_detail.java. I cannot figure out hat is wrong, please help!

You will be able to get your Intent in Activity's onCreate() method not in your fragment onCreateView() method because intent will be recevied by activity and not by fragment.
To get your intent in your movie_detail activity do it like this
static String detail="";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.movie_detail);
Intent intent =getIntent();
if (intent != null && intent.hasExtra(Intent.EXTRA_TEXT)) {
detail = intent.getStringExtra(Intent.EXTRA_TEXT);
}
}
After doing this you can use detail String to set Text in your textview
In your fragment class
((TextView) rootView.findViewById(R.id.movie_detail))
.setText(movie_detail.detail);

You must attach the fragment to your activity's layout in order to make you fragment visible in your activity
in your movie_detail activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.movie_detail);
Intent intent = getActivity().getIntent();
if (intent != null && intent.hasExtra(Intent.EXTRA_TEXT)) {
String detail = intent.getStringExtra(Intent.EXTRA_TEXT);
Log.v("Check", detail);
}
Bundle extra = new Bundle();
extra.putExtra(Intent.EXTRA_TEXT,detail);
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction =
fragmentManager.beginTransaction();
DetailFragment fragment = new DetailFragment();
fragment.setArguments(extra);
fragmentTransaction.replace(android.R.id.content, fragment);
}
And in your fragment get the arguments and set the details wherever necessary

App Crashed on BackPressed 3rd of 4th time

I am facing a strange issue in my android app and I am not able to figure it out. Is there anyone who can help me regarding this issue.
Let me describe about my app and issue.
I am getting all the images from gallery and displaying them on a gridview using adapter. Once displayed, I am sending an image from this gridview of Activity A to next activity on click of gridview item and assigning this image on an image view in Activity B... When I come back from Activity B to Activity A on pressing Bsck button, it works fine. But when I repeat this process three to four times, app is crashing. I don't know what is the issue.

Edit the setOnItemClickListener and insert a condition which checks for position of the item and starts and activity depending on the item clicked.
Should look something like this
listview.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0,View arg1, int position, long arg3) {
Intent n = null;
switch (position){
case 0:
n = new Intent(getActivity(), Class0.class);
break;
case 1:
n = new Intent(getActivity(), Class1.class);
break;
}
if(null!=n)
startActivity(n);
}
});
