NullPointerException but don't understand why - java

I have a DialogFragment which is supposed to display a VideoView and some TextViews. However, VideoView is null, along with other controls, even though the layout has been inflated.
Here is the code where I retrieve the pointer to various controls:
#Override
public void onViewCreated (View view, Bundle savedInstanceState) {
controls = new MediaController(getActivity());
title = (TextView) view.findViewById(R.id.title);
date = (TextView) view.findViewById(R.id.date);
description = (TextView) view.findViewById(R.id.description);
video = (VideoView) view.findViewById(R.id.video);
controls.setAnchorView(video);
video.setMediaController(controls);
}
But, debugger says otherwise:
Why are they null?
I have inflated the layout in create view where they are defined.

you need to some change
put your code
title = (TextView) view.findViewById(R.id.title);
date = (TextView) view.findViewById(R.id.date);
description = (TextView) view.findViewById(R.id.description);
video = (VideoView) view.findViewById(R.id.video);
from onViewCreated() to onCreateView() then bind data on onViewCreated() method.

there is :
at com.example.harimohan.myapplication.StartPage.onItemSelected(StartPage.java:174)
in line 174 you have choose and null value
maybe you should initilize blank1 in on create method .

You can try to check the where the null is in line 174 (the blank1.getSelectedItem() return the null value). It's helpful for you to solve the problem . Please forgive my English is poor.

getView() never called baseadapter getcount called

I am developing a gridview to display JSON images. I am entering ImageAdapter, but I am not receiving images in the screen indicating that something incorrect occurred while getting the associated view. Is MyArrList null?
I realize that there are other posts similar to my own out there, but I have done deep research into them and cannot find a solution.

Any suggestions/insight as to why I cannot receive images through getView() yet can get values for getCount() are appreciated. Thank you.

In your onCreate() method change getApplicationContext() to this in the line where you're creating adapter and remove notifyDataSetChanged().
And remove MyArrList duplicate from doInBackground()
Try to change your task as follows:
class LoadContentFromServer extends AsyncTask<Object, Integer, Object> {
#Override
protected Object doInBackground(Object... params) {
String url = "http://..no looking..";
JSONObject data;
try {
data = new JSONObject(getJSONUrl(url));
Log.v("data", data.toString());
JSONArray dataArray = data.getJSONArray("car_images");
/*
* TotalRows = Show for total rows
* TotalPage = Show for total page
*/
int displayPerPage = 9; // Per Page
int TotalRows = data.length();
int indexRowStart = ((displayPerPage * currentPage) - displayPerPage);
if (TotalRows <= displayPerPage) {
TotalPage = 1;
} else if ((TotalRows % displayPerPage) == 0) {
TotalPage = (TotalRows / displayPerPage);
} else {
TotalPage = (TotalRows / displayPerPage) + 1;
TotalPage = (int) TotalPage;
}
int indexRowEnd = displayPerPage * currentPage;
if (indexRowEnd > TotalRows) {
indexRowEnd = TotalRows;
}
for (int i = 0; i < dataArray.length(); i++) {
//HashMap<String, Object> map = new HashMap<String, Object>();
JSONObject c = dataArray.getJSONObject(i);
Log.v("getJSONObject(i)", dataArray.getJSONObject(i).toString());
// Thumbnail Get ImageBitmap To Object
HashMap<String, Object> map = new HashMap<String, Object>();
Bitmap bitmap = loadBitmap(c.getString(TAG_IMG));
Drawable d = new BitmapDrawable(getResources(), bitmap);
map.put(TAG_IMG, d);
Log.v("Bitmap", TAG_IMG);
MyArrList.add(map);
Log.v("MyArrList", MyArrList.toString());
Log.v("return0", MyArrList.toString());
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
return null;
}
#Override
protected void onPostExecute(Object result) {
Log.v("return3", MyArrList.toString());
// Disabled Button Next
if(currentPage >= TotalPage) {
btnNext.setEnabled(false);
}
else {
btnNext.setEnabled(true);
}
// Disabled Button Previous
if(currentPage <= 1) {
btnPre.setEnabled(false);
}
else {
btnPre.setEnabled(true);
}
setProgressBarIndeterminateVisibility(false);
imageAdapter.addAll(MyArrList);
imageAdapter.notifyDataSetChanged();
Log.v("return2", imageAdapter.toString());
Log.v("return2.1", MyArrList.toString());
}
}
and adapter:
class ImageAdapter extends BaseAdapter {
private Context mContext;
private ArrayList<HashMap<String, Object>> array;
public ImageAdapter(Context context) {
mContext = context;
array = new ArrayList<>();
}
#Override
public int getCount() {
Log.v("log", "getcount");
return array.size();
}
public Object getItem(int position) {
return array.get(position);
}
public long getItemId(int position) {
return position;
}
public void addAll(ArrayList<HashMap<String, Object>> list) {
array.clear();
array.addAll(list);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
//If convertView is null create a new view, else use convert view
if(convertView==null) {
Log.v("v", "convertView inflating");
convertView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate
(R.layout.activity_column, null);
}
Log.v("convertview", convertView.toString());
ImageView iv = (ImageView) convertView.findViewById(R.id.ColPhoto);
iv.setImageBitmap((Bitmap) array.get(position).get(TAG_IMG));
iv.setVisibility(ImageView.VISIBLE);
return v;
}
}

You need to call
protected String onPostExecute()
{
// change your data set here then call
imageAdapter.notifyDataSetChanged();
}
in onPostExecute() not in OnProgressUpdated() also you must call it when after you have modified the data set
EDIT
onProgressUpdate is normally for updating the ui (ie an progress bar). it will get called every time you call
protected String doInBackground()
{
// other code ommited
String progress = "test";
publishProgress(progress);
}
which you are not doing hence it will never update the data set.
try moving your code from the OnProgressUpdated to onPostExecute();

How to store a single row data into a string array of sqlite database in android

I have called a function returnCurrentNameById() by passing the id of the particular row. But it gives an error.
String[] s1;
public String[] returnCurrentNameById(int k) throws SQLException{
String[] columns = new String[]{ KEY_ID1, KEY_NAME, Key_DOB, KEY_AGE, KEY_PHONE_NO, Key_EXPERIENCE, KEY_EMAIL, KEY_STATUS, KEY_STATUS};
SQLiteDatabase db3 = this.getReadableDatabase();
Cursor c = db3.query(DATA_BASE_TABLE_NAME1, columns, KEY_ID1 + "=" + k, null, null, null, null);
if (c != null){
c.moveToFirst();
for(int i = 0; i<=8; i++){
s1[i] = c.getString(i);
}
return s1;
}
return null;
}

You have not initialized your s1 array.
Use
s1 = new String[9];
to allocate an array of 9 elements.
Also check the return value of moveToFirst() so you don't get an exception in case the query returns no rows.

Replace
Cursor c = db3.query(DATA_BASE_TABLE_NAME1, columns, KEY_ID1 + "=" + k, null, null, null, null);
with
Cursor c = db3.query(DATA_BASE_TABLE_NAME1, columns, KEY_ID1 + " = ?", new String[]{String.valueOf(k)}, null, null, null);

Null Pointer Exception in Bitmap.decodeResources() from xml resource

In my current android project I create two bitmaps from xml resources. Every time I build my project using the xml bitmaps as the resource for Bitmap.decodeResources() I get a null pointer exception when I try to access the bitmaps. But when I switch to using the straight .png the error goes away.
Why is decodeResources() returning null?
code where the bitmaps are created:
public OvertButton(float x, float y, float width, float height, int pressedId, int unPressedId, Resources res, boolean visible) {
\\these are null if xml bitmap is passed
pressed = BitmapFactory.decodeResource(res, pressedId);
unPressed = BitmapFactory.decodeResource(res, unPressedId);
this.visible = visible;
relocate(x, y);
resize(width, height); //throws NPE when I createScaledBitmap()
ClickableManager.registerClickable(this);
}
resource file
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="#drawable/play_button_pressed"
android:filter="false"
android:antialias="false"
android:dither="false"/>
and the resize method
#Override
public void resize(float width, float height) {
box.set(box.left, box.top, box.left + width, box.top + height);
Log.d("resize",String.valueOf(height));
pressed = Bitmap.createScaledBitmap(pressed, (int)width, (int)height, true);
unPressed = Bitmap.createScaledBitmap(unPressed, (int)width, (int)height, true);
}

This is a case of me being dumb but here is the answer for posterity.
Bitmap is not the same as BitmapDrawable
From the Drawable Resources link above:
COMPILED RESOURCE DATATYPE:
Resource pointer to a BitmapDrawable.
Thus I had to change this:
Bitmap pressed = BitmapFactory.decodeResource(res, R.drawable.play_button_pressed_res); //this is the id for the xml referring to the png
to either this:
Drawable pressed = res.getDrawable(R.drawable.play_button_pressed_res);
or this:
Bitmap pressed = BitmapFactory.decodeResource(res, R.drawable.play_button_pressed); //this is the id for the png
I decided to use bitmap because, as I understand, it is faster.

Trying to start an activity is causing an exception to be thrown, unsure why

Here is the code:
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = new ExpenseIcon(context);
((ExpenseIcon) convertView)
.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
System.out.println("Expense Icon Clicked");
Intent a = new Intent(context, ExpenseInput.class);
a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP & Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(a);
}
});
}
if (image == null)
image = BitmapFactory.decodeResource(context.getResources(), R.drawable.dollar);
((ExpenseIcon)convertView).setImageBitmap(image);
return convertView;
}
When I click on the ExpenseIcon button I get an exception thrown at the line context.startActivity(a):

I'm unsure why and not sure how to fix...

Try this,
Intent a = new Intent(context, ExpenseInput.class);
a.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(a);
