TextView update not happening when selected item from ListView

Hi I have Listview in that when I select an item I display another page where I am setting the text views with appropriate informations but when i select an item and go back and select another item the textviews are not getting updated ?BTW there are 10 text views can somebody provide me the solution for this? Thanks.

this is my listView code

}
mylistData.add(map);
}
SimpleAdapter arrayAdapter = new SimpleAdapter(this, mylistData, R.layout.rowmain, columnTags, columnIds);
list.setAdapter(arrayAdapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parnet, android.view.View view, int position, long id) {
new LongOperation().execute();
String text = list.getItemAtPosition(position).toString();
String g = text.replace("{col5=", "");
String g1 = g.replace(" col4=", "");
String g2 = g1.replace(" col7=", "");
String g3 = g2.replace(" col6=", "");
String g4 = g3.replace(" col1=", "");
String g5 = g4.replace(" col3=", "");
String g6 = g5.replace(" col2=", "");
String g7 = g6.replace(" col8=", "");
String val[] = g7.split(",");
for (int m = 0; m < val.length; m++) {
Log.d("VALUE", val[m]);
ar1.add(val[m]);
}
System.out.println(ar1);
Log.d("VALUES-------->", text);
mob = ar1.get(0);
Log.d("VALUE1", mob);
pin = ar1.get(1);
Log.d("VALUE2", pin);
lvo = ar1.get(2);
Log.d("VALUE3", lvo);
email = ar1.get(3);
Log.d("VALUE4", email);
ack = ar1.get(4);
Log.d("VALUE5", ack);
trade = ar1.get(5);
Log.d("VALUE6", trade);
name = ar1.get(6);
Log.d("VALUE7", name);
lvo2 = ar1.get(7);
Log.d("VALUE8", lvo2);
}
});
}

From your code: ar1.add(val[m]);
I guess that ar1 is a List<String> variable of your listview activity?
If that's true, maybe add a call to clear() may work:
ar1.clear();
for(int m =0 ; m< val.length ; m++)
{
Log.d("VALUE",val[m]);
ar1.add(val[m]);
}

Large ram consumption and occasional freezing in android app

So my app is taking up 80MB or RAM and occasionally when switching between activities, the screen goes black and it takes over a minute for the proper content to appear. All it does is load listviews in each activity. I made sure to execute all my AsyncTasks in the loading screen when the activity is first started, and I then use shared preferences to store the data and use it across all activities so that I don't have to execute a new Asynctask each time an activity is started. This is why I am puzzled as to why this happens. The only thing I can think of is that the activities don't get killed when I call finish() as this usually occurs when I switch between activities many times.
Sample Activity:
public class AllGameslistActivity extends Activity {
private Bet newBet = new Bet();
private double stake = 0.00;
private String name = "";
private double newwinnings;
private ArrayList<TipDisplayer> alltips = new ArrayList<>();

Trying to set the marker on the current position gives me nullpointer exception

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.

You can use PreferenceManager to save data and use it when the app is reloaded/restarted
sample:
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String text = tv1.getText().toString();
Log.e("text message", "" + text);
if(PreferenceManager.getDefaultSharedPreferences(MenuItemsActivity.this).getString("button", "").length != 0)
tv1.setBackgroundDrawable(getResources().getDrawable(R.drawable.blue_tab));
else
{
Editor editor = PreferenceManager.getDefaultSharedPreferences(MenuItemsActivity.this).edit();
editor.putString("button", "1");
editor.commit();
tv1.setBackgroundDrawable(getResources().getDrawable(R.drawable.blue_tab));
}
Toast.makeText(MenuItemsActivity.this, "clicked", 1000)
.show();
Intent i = new Intent(MenuItemsActivity.this,
MenuItemsActivity.class);
i.putExtra("category name", "" + text);
finish();
startActivity(i);
}

How to add two textViews to custom adapter?

i tried to add two textViews to list item.that data get from list. when the list print, it display correctly. But in list view its not print correctly. Can anyone help me?
This is the custom adapter class.
#Override
public View getView(int arg0, View convertView, ViewGroup arg2) {
// TODO Auto-generated method stub
final String text1 = listData.get(0);
final String text2 = listData.get(1);
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) this.context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.ratings_list, null);
}
TextView lblListHeader1 = (TextView) convertView.findViewById(R.id.textView1);
lblListHeader1.setText(text1);
TextView lblListHeader2 = (TextView) convertView.findViewById(R.id.textView2);
lblListHeader2.setText(text2);
return convertView;
}
This is the activity code.
public void ListDrwaer() {
try {
JSONObject jsonResponse = new JSONObject(strJson1);
JSONArray jsonMainNode = jsonResponse.optJSONArray("ratings");
for (int i = 0; i < jsonMainNode.length(); i++) {
JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
String restName = jsonChildNode.optString("rest_name");
listData = new ArrayList<String>();
if (restName.equalsIgnoreCase(name)) {
String userName = jsonChildNode.optString("user_name");
String rate = jsonChildNode.optString("rate");
String ratOut = "Rate : " + rate;
listData.add(userName);
listData.add(ratOut);
Log.d("Data", userName + rate);
}
}
} catch (JSONException e) {
Toast.makeText(getApplicationContext(), "Error..." + e.toString(),
Toast.LENGTH_LONG).show();
}
RatingsAdapter adapter = new RatingsAdapter(getApplicationContext(),
listData);
listView.setAdapter(adapter);
}
I want to add user name, below of that it's rate.
This is should be the output list.
01-23 11:59:09.102: D/Data(4873): omali 3.5
01-23 11:59:09.102: D/Data(4873): sunil 2
01-23 11:59:09.102: D/Data(4873): kuma#fh.com 1.5
01-23 11:59:09.102: D/Data(4873): fhhhy#ghj.com 0.5

First of all, the way you are building the list, it will never work, since you are deleting it and creating a new one in every iteration, so when you create the adapter, in the listyou only have the last item.
I would do:
ArrayList<Pair<String,String>> listData = new ArrayList<Pair<String,String>>(); //added
public void ListDrwaer() {
try {
JSONObject jsonResponse = new JSONObject(strJson1);
JSONArray jsonMainNode = jsonResponse.optJSONArray("ratings");
for (int i = 0; i < jsonMainNode.length(); i++) {
JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
String restName = jsonChildNode.optString("rest_name");
//removed listData = new ArrayList<String>();
if (restName.equalsIgnoreCase(name)) {
String userName = jsonChildNode.optString("user_name");
String rate = jsonChildNode.optString("rate");
String ratOut = "Rate : " + rate;
listData.add(new Pair<String,String>(userName,ratOut ));//added
//removed listData.add(userName);
//removed listData.add(ratOut);
Log.d("Data", userName + rate);
}
}
} catch (JSONException e) {
Toast.makeText(getApplicationContext(), "Error..." + e.toString(),
Toast.LENGTH_LONG).show();
}
RatingsAdapter adapter = new RatingsAdapter(getApplicationContext(),
listData);
listView.setAdapter(adapter);
}
Then, in the custom adapter class, you retrieve that data simply by
#Override
public View getView(int arg0, View convertView, ViewGroup arg2) {
// TODO Auto-generated method stub
//only this 3 lines change
Pair<String,String> item= listData.get(arg0);
final String text1 = item.first;
final String text2 = item.second;
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) this.context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.ratings_list, null);
}
TextView lblListHeader1 = (TextView) convertView.findViewById(R.id.textView1);
lblListHeader1.setText(text1);
TextView lblListHeader2 = (TextView) convertView.findViewById(R.id.textView2);
lblListHeader2.setText(text2);
return convertView;
}

You are always printing the wrong data, regardless of the position of the item
final String text1 = listData.get(0);
final String text2 = listData.get(1);
So Better take the Different lists of the username and ratOut and display the data
final String text1 = userNameListData.get(arg0);
final String text2 = ratOutListData.get(arg0);
Here arg0 is the position

Replace this:
final String text1 = listData.get(0);
final String text2 = listData.get(1);
with:
final String text1 = listData.get(2*arg0);
final String text2 = listData.get((2*arg0)+1);

change to:
final String text1 = listData.get(arg0*2);
final String text2 = listData.get(arg0*2+1);
and override:
#Override
public int getCount() {
// TODO Auto-generated method stub
return listData.size()/2;
}
As you are adding both the text in one arraylist 0,1 belong to first item and 2,3 belong to 2nd and so on.
Also size of the list view item would be half of the size of arraylist.
Try this.
also change this:
listData = new ArrayList<String>();//<--out side for loop
for (int i = 0; i < jsonMainNode.length(); i++) {
JSONObject jsonChildNode = jsonMainNode.getJSONObject(i);
String restName = jsonChildNode.optString("rest_name");
if (restName.equalsIgnoreCase(name)) {
String userName = jsonChildNode.optString("user_name");
String rate = jsonChildNode.optString("rate");
String ratOut = "Rate : " + rate;
listData.add(userName);
listData.add(ratOut);
Log.d("Data", userName + rate);
}
}
