ListView Scrolling Problem and Performance Tips

I want to know something...
What's wrong about my ListView, the problem is when I perform a fast scroll sometimes my application stopped...
In my MainActivity extending the a4 class ----> that extends Activity class:
ArrayList<a> AL;
static ListView LV;
SearchView SV;

Thank you for your help... I will really appreciate it... Also I need tips about the performance of my existing code and please write your answer in java and don't use support libraries cuz I want my application work for android phones below android 5...

I've found out that the problem is at my list adapter so I edited it into this:

TimePicker custom preference for androidx.preference.DialogPreference

I'm trying to convert a TimePicker preference dialog extended from android.support.v7.preference.DialogPreference to the same but extended from androidx.preference.DialogPreference.
Here is the code of the original custom preference :
package com.example.example;
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;
import android.content.Context;
import android.content.res.TypedArray;
import android.preference.DialogPreference;
import android.util.AttributeSet;
import android.view.View;
import android.widget.TimePicker;
public class TimePreference extends DialogPreference {
private int mHour = 0;
private int mMinute = 0;
private TimePicker picker = null;
private final String DEFAULT_VALUE = "00:00";
public static int getHour(String time) {
String[] pieces = time.split(":");
return Integer.parseInt(pieces[0]);
}
public static int getMinute(String time) {
String[] pieces = time.split(":");
return Integer.parseInt(pieces[1]);
}
public TimePreference(Context context) {
this(context, null);
}
public TimePreference(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public TimePreference(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setPositiveButtonText("Set");
setNegativeButtonText("Cancel");
}
public void setTime(int hour, int minute) {
mHour = hour;
mMinute = minute;
String time = toTime(mHour, mMinute);
persistString(time);
notifyDependencyChange(shouldDisableDependents());
notifyChanged();
}
public String toTime(int hour, int minute) {
return hour + ":" + minute;
}
public void updateSummary() {
String time = mHour + ":" + mMinute;
setSummary(time24to12(time));
}
#Override
protected View onCreateDialogView() {
picker = new TimePicker(getContext());
return picker;
}
#Override
protected void onBindDialogView(View v) {
super.onBindDialogView(v);
picker.setCurrentHour(mHour);
picker.setCurrentMinute(mMinute);
}
#Override
protected void onDialogClosed(boolean positiveResult) {
super.onDialogClosed(positiveResult);
if (positiveResult) {
int currHour = picker.getCurrentHour();
int currMinute = picker.getCurrentMinute();
if (!callChangeListener(toTime(currHour, currMinute))) {
return;
}
// persist
setTime(currHour, currMinute);
updateSummary();
}
}
#Override
protected Object onGetDefaultValue(TypedArray a, int index) {
return a.getString(index);
}
#Override
protected void onSetInitialValue(boolean restorePersistedValue, Object defaultValue) {
String time = null;
if (restorePersistedValue) {
if (defaultValue == null) {
time = getPersistedString(DEFAULT_VALUE);
}
else {
time = getPersistedString(DEFAULT_VALUE);
}
}
else {
time = defaultValue.toString();
}
int currHour = getHour(time);
int currMinute = getMinute(time);
// need to persist here for default value to work
setTime(currHour, currMinute);
updateSummary();
}
public static Date toDate(String inTime) {
try {
DateFormat inTimeFormat = new SimpleDateFormat("HH:mm", Locale.US);
return inTimeFormat.parse(inTime);
} catch(ParseException e) {
return null;
}
}
public static String time24to12(String inTime) {
Date inDate = toDate(inTime);
if(inDate != null) {
DateFormat outTimeFormat = new SimpleDateFormat("hh:mm a", Locale.US);
return outTimeFormat.format(inDate);
} else {
return inTime;
}
}
}
If I try to use that directly in my preference fragment, the app crashed with the following error :
android.view.InflateException: Binary XML file line #27: Error inflating class com.example.example.TimePreference
...
Caused by: java.lang.ClassCastException: com.example.example.TimePreference cannot be cast to androidx.preference.Preference
That's normal, considering the fact that my custom preference is not an androidx.preference
I haven't found any information on how to convert an old android.support.v7.preference to a new androidx.preference. Does anyone know how to do so ?
Thanks a lot !

PullToRefreshListView leaves space on top

I am using PullToRefreshListView to provide data reload when pulling the listview.
But my problem is that after refreshing, the layout leaves a space on top of the listview. See the image below:
I want to remove the space on top. I tried setting the view to View.GONE but it still leaves a small space in it.

I would suggest you to Just disable listview onrefresh listener and
use android.support.v4.widget.SwipeRefreshLayout instead of pull to refresh listview . It is very easy to use.
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/refreshLater"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
***Place Your listview here***
</android.support.v4.widget.SwipeRefreshLayout >
you can set refresh listener on it like this:
public SwipeRefreshLayout swipeRefreshLayout;
swipeRefreshLayout = (SwipeRefreshLayout)findViewById(R.id.refreshLater);
swipeRefreshLayout.setOnRefreshListener(this);
you can do needed code in the below override method:
#Override
public void onRefresh()
{
swipeRefreshLayout.setRefreshing(false);
}

PagerSlidingTabStrip android tab click listener not working

I am using PagerSlidingTabStrip in an Android project.
When I swipe through the tabs, it is working correctly.
However, when I click on a tab, the tab does not change.
Here is the activity XML:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"

Here is my code in onCreate():
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my_progress);
this.viewPager = (ViewPager)this.findViewById(R.id.progressViewPager);
this.pagerAdapter = new MyProgressFragmentPagerAdapter(this.getSupportFragmentManager());
this.viewPager.setAdapter(this.pagerAdapter);
PagerSlidingTabStrip pagerTabStrip = (PagerSlidingTabStrip)this.findViewById(R.id.progress_pager_tab_strip);
pagerTabStrip.setViewPager(this.viewPager);
pagerTabStrip.setTextColorResource(R.color.meTabText);
}
Any advice on how to click the buttons to also change the tabs would be greatly appreciated!

cannot find symbol method onActivityResult(int,int,Intent)

Im following the tutorial of In-app Billing from the following link:
Android Studio Google Play In-app Billing Tutorial.
Im implementing this logic in a Contact Adapter class which extends Base Adapter. In tutorial it is implemented in a class which extends Activity.
Error comes on onActivityResult(). I read several questions on this and I understand this method should be written in class which extends Activity but in my case the scenario is different.
Is there any way to solve this without writing onActivityResult method in MainActivity class.. and if not what should I do?

I recommend you to create an activity just to process this payment and then you can back to your normal flow.
