how to work on BUY NOW button in android?

how to work on BUY NOW button in android? - android

I am developing an Android eCommerce application in which there are two different buttons. The first one is an ADD TO CART button and the other one is a BUY NOW button.
When I click on the ADD TO CART button, it successfully places the item in the cart and after I click on the cart button, the app proceeds to the Cart Activity. I did the same for BUY NOW but the issue is how do I update my cart and move to Cart Activity on a single click?

try cancelling your Async task execution during onBackPressed()
Declare:
Public getDataTask asyncFetchData;
asyncFetchData = new getDataTask();
asyncFetchData.execute();
Now in your Fragment:
#Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
getView().setFocusableInTouchMode(true);
getView().requestFocus();
getView().setOnKeyListener(new View.OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
if (asyncFetchData!= null)
asyncFetchData.cancel(true);
Toast.makeText(getActivity(), "Back pressed...", Toast.LENGTH_SHORT).show();
return true;
}
}
return false;
}
});
}
Also in doInBackground notify the AsyncTask to cancel execution
#Override
protected Void doInBackground(Void... arg0) {
// TODO Auto-generated method stub
// parse json data from server in background
parseJSONData();
if (isCancelled()) break;
return null;
}

Using android radio button to execute method

I have 2 radiobuttons and 1 button. I want that when i click the normal button it checks which radio button is checked and executes a method based on that. The following is the code i have used but the app crashes when i click the button
#Override
public void onClick(View v) {
radioGroup = (RadioGroup) v.findViewById(R.id.radioPost);
rdpublic=(RadioButton) v.findViewById(R.id.radioPublic);
rdprivate=(RadioButton) v.findViewById(R.id.radioPrivate);
radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener()
{
public void onCheckedChanged(RadioGroup group, int checkedId)
{
if(rdpublic.isChecked())
{
new PostPublic().execute();
}
else if(rdprivate.isChecked())
{
new PostPrivate().execute;
}
}
});
}

Try this.....
normalBtn= (Button) findViewById(R.id.Btn);
rdpublic=(RadioButton) findViewById(R.id.radioPublic);
rdprivate=(RadioButton) findViewById(R.id.radioPrivate);
normalBtn.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
try {
if(rdpublic.isChecked())
{
new PostPublic().execute();
}
else if(rdprivate.isChecked())
{
new PostPrivate().execute;
}
}catch(Exception e)
{
e.printStackTrace();
}
}
});

Why are you using the button view to find the RadioButtons and Group? Instead of v.findViewById, you should just use findViewById.

your code assumes that your Buttons or RadioButtons are child Views of the passed View v. Which is actually wrong and that is why you are getting an NPE.

This is the full code.

You can use Collections and ArrayList also to sort out as per below.
Collections.sort(YourArrayList);

You can sort your adapter backing the ListView by that listview will automatically sort.

Use an ArrayAdapter, order the elements inside the array asociated whit the adapter by your integer and link the adapter to your listView.

return save;
}else {
return "Not Found";
}
}catch(Exception exception){}
return null;
}
}
}
Where the custome class is extends from base adapter in order to have list view with image view set to video image and text view set to video title.
In log cat messages the result are existed but my list view returns empty.
Can any one tell me why?
here is the code for costume list view:
public class custome extends BaseAdapter {
ArrayList<videos> data=new ArrayList<videos>();
android.content.Context context1;
android.widget.TextView name;
ImageView picture;
public custome(Context context,ArrayList<videos>arrayList) {
// TODO Auto-generated constructor stub
context=context;
arrayList=data;
}
public int getCount() {
// TODO Auto-generated method stub
return data.size();
}
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return data.get(arg0);
}
public long getItemId(int arg0) {
// TODO Auto-generated method stub
return arg0;
}
public View getView(int arg0, View arg1, ViewGroup arg2) {
View view=arg1;
if(view==null)
{
LayoutInflater layoutInflater=(LayoutInflater) _c.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view=layoutInflater.inflate(R.layout.listvideo,null);
}
name=(TextView) view.findViewById(R.id.textView1);
picture=(ImageView) view.findViewById(R.id.imageView1);
videos video = data.get(arg0);
name.setText(video.getVideoname());
URL url = null;
try {
url = new URL(video.getImageurl());
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Bitmap bitmap = null;
try {
bitmap = BitmapFactory.decodeStream(url.openConnection().getInputStream());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
picture.setImageBitmap(bitmap);
return view;
}
}

The problem is in your assigning code of custome constructor:
Use this constructor:
public custome(Context context,ArrayList<videos> arrayList) {
context=context;
//arrayList=data;<<< WRONG
data=arrayList;//<<<<<<< Correct way of assigning
}

You are overriding your adapter here:
listview.setAdapter(new custome(MainActivity.this,videolist));
Remove this line
