Hello, my old code is working, but the problem is that when i am clicking tablerow it call another activty, but it not set that table row data but it setting last array data to that activity.
Means it set the last array value to next screen activity.
for ( j = 0; j < dataListfeture.size(); j++)
{
HashMap<String, String> hm = new HashMap<String, String>();
hm = dataListfeture.get(j);
final TableRow tblrow = new TableRow(MainScreen.this);
final View rowView = inflater.inflate(R.layout.featuredrow, null);
tblrow.setId(j);
tblrow.getId();
featuredName = (TextView) rowView.findViewById(R.id.xxName);
featuredDistance = (TextView) rowView.findViewById(R.id.xxDistance);
featuredVeneType = (TextView) rowView.findViewById(R.id.xxVeneType);
featuredPhone = (TextView) rowView.findViewById(R.id.xxPhone);
featuredAddress = (TextView) rowView.findViewById(R.id.xxAddress);
Drawable image = ImageOperations(MainScreen.this, hm.get("url"), "image.jpg");
featuredImage = (ImageView) rowView.findViewById(R.id.xxdImage);
featuredImage.setImageDrawable(image);
featuredName.setText("" + hm.get("name"));
featuredDistance.setText("" + hm.get("distance") + " mi");
featuredVeneType.setText("" + hm.get("venuetype"));
featuredPhone.setText("" + hm.get("phonenumber"));
featuredAddress.setText("" + hm.get("address"));
mapnamelist = hm.get("name");
mapvenuelist = hm.get("venuetype");
mapothervenuelist = hm.get("othervenuetype");
mapaddresslist= hm.get("address");
mapcitylist= hm.get("city");
mapstatelist= hm.get("state");
tblrow.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View v)
{
final ProgressDialog progDailog = ProgressDialog.show(MainScreen.this, null, "Loading ....", true);
final Handler handler = new Handler()
{
public void handleMessage(Message msg)
{
System.out.println("search");
Intent myIntent = new Intent(MainScreen.this, xxxxscreen.class);
startActivity(myIntent);
MainScreen.this.finish();
progDailog.dismiss();
}
};
new Thread()
{
public void run()
{
try
{
System.out.println();
handler.sendEmptyMessage(1);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}.start();
}
});
Create an int array of id say array_id[] and after setting id to table row add that id to array_id[] also like
tblrow.setId(j);
array_id[j] = j;
And in onClick method do this:
for(int i = 0;i< array_id.length;i++)
{
TableRow tbl_row = (TableRow) findViewById(i);
if(v.getId() == array_id[i])
{
/** Perform your Operations */
}
}

create relative layout object from it layout id, then you can add it as below
relativeLayout = findViewById(R.id.yourRelativeLayoutId);
relativeLayout.addView(yourView);
Listview or recyclerview is best for practice but as you want to use textview, you can use like this in your code:
RelativeLayout relativeLayout =
(RelativeLayout) findViewById(R.id.rootlayout);
TextView textView = new TextView(this);
textView.setText("Hey, I am TextView");
relativeLayout.addView(textView);
appending a textview to relativelayout is pretty simple.
just use
TextView textview = new TextView(this);
textview.setText("Text");
relativelayoutobject.addView(textview);
to setup the position use
textview.setLayoutParams(thelayoutparams)
But if you use big database, please, use 'TableLayout' instead of your method due to performance reasons.
Define relative layout in your xml layout. Add multiple textview programmatic ally like this-
RelativeLayout relativeLayout = (RelativeLayout) findViewById(R.id.relativeLayout);
//use a for loop to define multiple textView in RelativeLayout
//length is no. of textView you required
for (int i = 0; i < length; i++) {
TextView tv = new TextView(relativeLayout.getContext());
tv.setText("Text from sqlite database");
tv.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT));
relativeLayout.addView(tv);
}
I have done the following things in my program:
I am generating some Buttons programmatically in my MenuItemsActivity class. I have a Listview in the xml of the MenuItemsActivity class.
When I click on the button the appropriate contents get loaded in the Listview. I just refresh the activity i.e I am using the same Listview to load different contents based on the button which is clicked.
I want to do the following:
When the Button is clicked I want to change the background of the button to 'blue_tab` and maintain that same color when the same activity reloads. Can anyone guide me step by step what to do, as I am a newbie to Android.

editor.putString("button", "1");
editor.commit();
tv1.setBackgroundDrawable(getResources().getDrawable(R.drawable.blue_tab));
}

.show();
Intent i = new Intent(MenuItemsActivity.this,
MenuItemsActivity.class);
i.putExtra("category name", "" + text);
finish();
startActivity(i);
}

You need to check whether the string you are parsing is an integer. Try this code:
if (IsInteger(point[i].getText().toString()))
totalscore[i] =Integer.parseInt(point[i].getText().toString());
and add this function:
public static boolean IsInteger(String s)
{
if (s == null || s.length() == 0) return false;
for(int i = 0; i < s.length(); i++)
{
if (Character.digit(s.charAt(i), 10) < 0)
return false;
}
return true;
}
I hope this helps

The problem appears to be with creating new items to add to the view, lines like this
View v = new View(R.layout.getlist);
Is my overall structure ok or do I need to do this another way?
1.Usually we show the busy dialog in the onPreExecute of the
asyncTask.
2.You need to inflater your views thanks to an inflater.
LayoutInflater li = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = li.inflate(R.layout.view, null);
Hope this will help you.
I am making a number of imageViews programmatically in a loop and assigning them ids. But when in onClick method I need to get the id of images, it is returning the id of the last image only. How do I get the id of the image that is clicked?
The code I am using:
for (int j = 0; j < 5; j++) {
TableRow tr = new TableRow(this);
imageUrl = "http://ondamove.it/English/images/users/";
imageUrl = imageUrl + listObject.get(j).getImage();
image = new ImageView(this);
image.setPadding(20, 10, 0, 0);
image.setId(j+1);
tr.addView(image);
try {
new DownloadFileAsync(image, new URL(imageUrl))
.execute(imageUrl);
images.add(image);
//images = new ImageView[5];
}
catch (Exception e) {
e.printStackTrace();
}
tr.addView(image);
table.addView(tr, new TableLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
image.setOnClickListener(clickImageListener);
Following is the onclicklistener.
private OnClickListener clickImageListener = new OnClickListener() {
public void onClick(View v) {
imageId = image.getId();
Intent fullScreenIntent = new Intent(v.getContext(),FullImageActivity.class);
fullScreenIntent.putExtra(ProfilePageNormalUser.class.getName(),imageId);
ProfilePageNormalUser.this.startActivity(fullScreenIntent);
}
};
Inside the onClick(View v) method you can call v.getId() - this will return you the ID of the View being clicked. Hope this helps.
Try this out:
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
int index = 0;
for (int i = 0; i < image.length; i++)
{
if (image[i].getId() == v.getId())
{
index = i;
break;
}
}
Toast.makeText(this, "Image clicked index => "+index, Toast.LENGTH_SHORT).show();
}
