Smooth scrolling in listview with multiple row layouts - android

I have a listview which inflates 4 different types of row layouts depending on the position(overriden getViewTypeCount() and getItemViewType(int position) to achieve it) .Each row has an Image and other textviews and buttons . I am loading the image in a seaparate thread . I am using android viewholder pattern to cache the viewholders for each row type .
When I scroll from one kind of row layout to another row layout I observe a jerkiness in scrolling .
Any pointers to improve will be appreciated.

Make sure you do not load or process any images in Adapter.getView() method. If you need to do so, do it in a separate AsyncTask. If you download images from Internet you should better use some helper libraries like Volley or Picasso

I use this library to load images in list view, I never had a problem:Android Image Loader

txtshowpeoplearray[d].setVisibility(View.VISIBLE);
txtpeopleshowdatearray[d].setVisibility(View.VISIBLE);
btnpeopleviewarray[d].setVisibility(View.VISIBLE);
btnpeopledeletearray[d].setVisibility(View.VISIBLE);
txtshowpeoplearray[d].setText(dformname2[d]);
txtpeopleshowdatearray[d].setText(dregdate2[d]);
}
these codes into a Button click listener and
pref.getstrings works Properly when runs for 2 times(button clicked for 2 times) !

In my app I am fetching the order details from the mysql db and based on the number of rows in db I am dynamically adding the TextView in my LinearLayout in the app(if there are 6 rows then 6 text views will be displayed in the app)
In doing the toolbar is disabled from the Activity and due to this i am NOT able to go back to my parent activity
I am NOT sure but I think using setLayoutParams is the culprit here.
Please help!

Remove this code it is not needed:

((ViewGroup)this.scrollView.getParent()).removeView(this.scrollView);
setContentView(this.scrollView);
Move reading from DB to AsyncTask - because you are blocking UI thread on call to getData() and Application freezes durring loading.
Also you need think about using proper container like ListView or RecycleView

i searched a lot to find how initialize Time variables in my Android project, i have tried to use Set(); methode but doesn't work, i need your help thank's ` here is my source code :
TableRow tableRow;
Time HourProgram;
int H = 12000, M = 1200;
int averageConsultationTime = 30;
// String
// TableSettinHourgHeader=""+HourBegen+"H"+averageConsultationTime+"|"
// +HourBegen+"H"+averageConsultationTime+"|"
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.table);
Log.i("OK", "onCreateOK");
Log.i("OK", "HMOK");
TextView DynamicButton = new TextView(MainActivity.this);
tableRow = (TableRow) findViewById(R.id.tr1);
LayoutParams layoutparams = new TableRow.LayoutParams(
LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
DynamicButton.setLayoutParams(layoutparams);
String ss = converteur(H, M);
Log.i("OK", "converteur(H, M)OK" + ss);
DynamicButton.setText("Assalam Aleikum " + ss);
Log.i("OK", "setTextOK" + ss);
tableRow.addView(DynamicButton);
}
#SuppressWarnings("unused")
private String converteur(int timeBegen, int averageConsultationTime) {
String sTb = "" + String.valueOf(timeBegen).toString();
String sAct = ""
+ String.valueOf(this.averageConsultationTime).toString();
// Toast.makeText(this,
// ""+timeBegen+"H"+averageConsultationTime,Toast.LENGTH_LONG);
return "timeBegen : " + sTb + " averageConsultationTime : "
+ averageConsultationTime;
}
`

For
java.sql.Time
It should be
Time HourProgram = new Time(System.currentTimeMillis());
Also, if you prefer Calendar then,
Time HourProgram = new Time(Calendar.getInstance().getTimeInMillis());

In my "FilterChoice" activity, I create the layout dynamically. I create a Radio Group and add Radio Buttons in it depending on the size of an ArrayList. There's a list in my "Filters" activity. The radio buttons are different depending on the filters clicked. When I click "Prices" filter, it views six items on the "FilterChoice" activity. Then pressing back button, when I click "Categories" filter, the checkedId's in the onCheckedChanged() starts from seven, instead of one. Why does it not start from one in the new activity call? How to solve it? Here's my "FilterChoice" activity.

I have not yet figured out the behavior you describe, but I would point out that you can set the IDs of the RadioButtons you're creating dynamically. For example, in your "Categories" block:
for (int i = 0; i < SearchResults.cate.size(); i++) {
rb = new RadioButton(FilterChoice.this);
rb.setId(i + 1);
rb.setText(SearchResults.cate.get(i).key + " ("
+ SearchResults.cate.get(i).value + ")");
rg.addView(rb);
}
This will set IDs from 1 to SearchResults.cate.size(), which I believe is what you're going for.
