Hi could someone advise me on whats wrong with the following code. The logcat says its in the onCreate method. all seems to be correct in the mainactivity as i have passed the bundle with the string.
#SuppressLint("NewApi")
public class CurrentBookingFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {
View view =inflater.inflate(R.layout.current_booking_fragment, container, false);
Bundle bundle = this.getArguments();
String strtext = this.getArguments().getString("GetStringPUFirstLine");
TextView CurrentBookingFragmentTV = (TextView)view.findViewById(R.id.CurrentBookingFragmentTV);
CurrentBookingFragmentTV.setText(strtext);
return view;
}
}
Here is the log:

Creating the fragment:
Fragment CurrentBookingFragment;
CurrentBookingFragment = new CurrentBookingFragment();
FragmentManager fm = getFragmentManager();
Bundle bundle=new Bundle();
bundle.putString("GetStringPUFirstLine", "GetStringPUFirstLine");
CurrentBookingFragment.setArguments(bundle);
FragmentTransaction fragmentTransaction = fm.beginTransaction();
fragmentTransaction.replace(R.id.BookingFragment, CurrentBookingFragment);
fragmentTransaction.commit();
Try setting the text in onActivityCreated(){}.
#Override
public void onActivityCreated(Bundle savedInstanceState)
{
TextView CurrentBookingFragmentTV = (TextView)view.findViewById(R.id.CurrentBookingFragmentTV);
CurrentBookingFragmentTV.setText(strtext);
}

everything is mainly explained in the title ill go in as much detail as i can. I am making an android game app i created a unique id for a circle that is drawn in canvas in the DrawingView class since this cannot be referenced in xml i had to create the id as an int in java so that java could find the id and use it as the button. Im sure you are all very confused by now i will continue will putting in my best effort to explain. below is the code for the Main file that gets called
public class Main extends Activity {
DrawingView v;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
LinearLayout layout1 = new LinearLayout (this);
FrameLayout game = new FrameLayout(this);
DrawingView v = new DrawingView (this);
TextView myText = new TextView(this);
int w = getResources().getInteger(DrawingView.redColor);
Button redCircle = (Button) findViewById(w);
redCircle.setWidth(300);
redCircle.setText("Start Game");
layout1.addView(myText);
layout1.addView(redCircle);
//redCircle.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
game.addView(v);
game.addView(layout1);
setContentView(game);
redCircle.setOnClickListener((OnClickListener) this);
}
public void onClick(View v) {
Intent intent = new Intent(this, Main.class);
startActivity(intent);
// re-starts this activity from game-view. add this.finish(); to remove from stack
}
#Override
public boolean onCreateOptionsMenu(Menu menu){
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
and not really neccessary but to help you understand what i am trying to accomplish here is the DrawingView class that creates random circles either green or red below.
public class DrawingView extends View {
public DrawingView(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
RectF rectf = new RectF(0, 0, 200, 0);
private static final int w = 100;
public static int lastColor = Color.BLACK;
private final Random random = new Random();
private final Paint paint = new Paint();
private final int radius = 230;
private final Handler handler = new Handler();
public static int redColor = Color.RED;
public static int greenColor = Color.GREEN;
private final Runnable updateCircle = new Runnable() {
#Override
public void run() {
lastColor = random.nextInt(2) == 1 ? redColor : greenColor;
paint.setColor(lastColor);
invalidate();
handler.postDelayed(this, 1000);
}
};
#Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
handler.post(updateCircle);
}
#Override
protected void onDetachedFromWindow() {
super.onDetachedFromWindow();
handler.removeCallbacks(updateCircle);
}
#Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
// your other stuff here
canvas.drawCircle(random.nextInt(canvas.getWidth()-radius/2) + radius/2f, random.nextInt(canvas.getHeight()-radius/2) + radius/2f, radius, paint);
}
//Bitmap.Config conf = Bitmap.Config.ARGB_8888; // see other conf types
//private int h = 100;
//#SuppressLint("DrawAllocation")
//Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap
//Canvas canvas = new Canvas(bmp);
/*
private Object canvas(Bitmap bmp) {
// TODO Auto-generated method stub
return null;
}
*/
}
and more importantly the log cat errors that display after the app crashes

canvas.drawCircle(random.nextInt(canvas.getWidth()-radius/2) + radius/2f, random.nextInt(canvas.getHeight()-radius/2) + radius/2f, radius, paint);
Because the Object canvas do not have width or height (it is null)
Reason :
Your code adds views like :
LinearLayout layout1 = new LinearLayout (this);
FrameLayout game = new FrameLayout(this);
DrawingView v = new DrawingView (this);
TextView myText = new TextView(this);
int w = getResources().getInteger(DrawingView.redColor);
Button redCircle = (Button) findViewById(w);
redCircle.setWidth(300);
redCircle.setText("Start Game");
layout1.addView(myText);
layout1.addView(redCircle);
//redCircle.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
game.addView(v);
game.addView(layout1);
But at the time of
game.addView(v);
v do not have any views referenced so the null object view is added in
game
So pls add some view i.e. Text or Images in v first and then call
game.addView(v);
This is solution for your error

I've been trying to get my list view to work for quite some time now, I just changed my listener from onClick to onItemClick to handle listview items better but the app crashes once again, my code below, any help would be appreciated.
Class:
public class ListViewAdapterProduct extends BaseAdapter {
Context mContext;
ListView listView = (ListView) findViewById(R.id.listview1);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View v, int position, long id){
Resources res = mContext.getResources();
productTitleArray = res.getStringArray(R.array.titles_product);
for (String productTitle : productTitleArray)
{
if(productTitle.equals("productOne"))
{
Log.d("Msg", "Found");
}
else
{
Log.d("Msg", "Not Found");
}
}
}
});

You have declared the mContext, but you have not initialized it.
You can do this in the constructor of your adapter:
public class ListViewAdapterProduct extends BaseAdapter {
Context mContext;
// the construcor that initializes the context
public ListViewAdapterProduct(Context c){
mContext = c;
}
...
However, the trace that you have posted, suggest that the problem is in your adapter's getView() method, on line 91. You should check that also.
ListViewAdapterproduct.getView(ListViewAdapterproduct.java:91)
Edit:
list.setAdapter(adapter);
In this line the adapter is null, you did not initialize it... (you set your adapter twice, first with null).
It is a good practise to define your variables locally, and make them class variable only when you actually need it. This way its harder to forget about initialization.
you have a problem in Context mContext; is null
in your activity set mContext = this; so mContext would be the activity context you will be able to use the resources
this is the correct code :
since your already sent this in your adapter you need to catch it there
public class ListViewAdapterProduct extends BaseAdapter {
Context mContext;
ArrayList<ClassproductList> arraylist;
ListView listView = (ListView) findViewById(R.id.listview1);
//add this
public ListViewAdapterProduct (Context mContext,ArrayList<ClassproductList> arraylist)
{
this.mContext = mContext;
this.arraylist = arraylist;
}
SOLVED !!!
I changed back from onItemClick (complicated to use with custom adapter) to onClick (simple to use with custom adapter) and applied:
view.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
String mytitle=holder.title.getText().toString();
if(mytitle.equals("ProductOne")){
Intent intent1 = new Intent(mContext, ProductClass.ProductOne);
mContext.startActivity(intent1);
...
}
}
Had to add:
String mytitle=holder.title.getText().toString();
i am trying to download a .txt file from internet and then read it and execute it.
i had success in downloading, reading and executing a single line query file.
but the problem is i cant execute multi line query from the file. i did some research and they did not suit my needs so i came up with a solution but i cant figure out some errors.
my idea is to convert a .txt file, line by line to a List and then for each String in the List execute a query within sqlite.
here's some of my code :
public void updateDB(View v){
new DownloadFileFromURL().execute(file_url);
File file = new File(Environment
.getExternalStorageDirectory().toString()
+ "/update.txt")
Log.i("UPDATE", "SQL DOWNLOADED");
while(start.equals(true)){
List<String> list = readUpdate2("update.txt");
for (String string : list) {
datasource.executeRaw(string);
Log.i("UPDATE", "EXEC SQL # : " + list.size());
}
file.delete();}}
public List<String> readUpdate2(String url){
File sdcard = Environment.getExternalStorageDirectory();
//Get the text file
List<String> list = null;
File file = new File(sdcard,url);
try {
BufferedReader br = new BufferedReader(new FileReader(file));
String line;
while((line = br.readLine()) != null) {
// this is where the error happens :
list.add(line);
Log.i("UPDATE", "LINE : " + line);
}
}
catch (IOException e) {
}
return list;
}
the problem is i am stuck with a Nullpointer exception. it says the line is empty.

so basically i am getting no text from the .txt file and then i cannot add anything to my List. what should i do ?
thanks in advance
This is probably the reason of null pointer exception:
List<String> list = null;
Try assigning a new list instead of null
this answer comes from here: 2Darray to 1darray with for loop
I don´t know if I can reopen it once it was answered.. my apologies if that's the case.
I modified a little that function to end like this:
public String[] initarray() {
xFINAL = new String [data_array.length];
int i = 0;
int j=0;
int UMB1 = 100;
int l = data_array.length;
for (i=0 ; i < l ; i++) {
LATIT = Double.parseDouble(data_array [i][2]);
LONGIT = Double.parseDouble(data_array [i][3]);
dist = calculateDistanceByHaversineFormula(Localizacion.LONGITUD_D, Localizacion.data_arrayUD_D,LONGIT, LATIT);
if (dist < UMB1){
xFINAL[j++] = data_array [i][0];
System.out.println(Arrays.toString(xFINAL));
System.out.println("j++" + data_array[i][0]);
}
}
return xFINAL;
}
dist = the difference in meters between 2 locations, returning an int.
data_array is already defined before.
It's "kind of working". What I get from that code is an array like this(data1 and data3 are inside the condition, data2 would be false)
[data1 , data3 , null]
And should be like this instead I think:
[data1, data3]
The error comes when I am trying to use that xFINAL array with an spinner:
public final void rel() {
String[] array_spinner = MYSQL.xFINAL;
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_dropdown_item, array_spinner);
spinnerArrayAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
sp_1.setAdapter(spinnerArrayAdapter);
}
When I try to load the spinner it gives me the following:

System.out.println(Arrays.toString(xFINAL));
This line should be after for loop completes.
For references (anything that holds an object) that is null.
For int/short/byte that is a 0.
For float/double that is a 0.0
For booleans that is a false.
When you create an array of String, all entries are null initially. Your array size is 3 I think so initially it is initialized with [null,null, null]. Two null get replaced with the values and one remains as it is.
EDIT: Use ArrayList instead Array
List<String> list = new ArrayList<String>();
for (i=0 ; i < l ; i++) {
LATIT = Double.parseDouble(data_array [i][2]);
LONGIT = Double.parseDouble(data_array [i][3]);
dist = calculateDistanceByHaversineFormula(Localizacion.LONGITUD_D, Localizacion.data_arrayUD_D,LONGIT, LATIT);
if (dist < UMB1){
list.add(data_array [i][0]);
System.out.println(list);
System.out.println(list.get(i));
}
}
