Try replacing

Android: How to create a filtering function with Checkbox

I am trying to create a filtering function with checkbox for my application. I have populated a list of installed application and i want to filter out only a few it. My idea is to get those checkbox that are checked and store it into an array. After which, display it back into a listview.
Example:
For this example, i would like to only list out Maps and Camera upon clicking on the submit button.
Does anyone know what should i do to achieve this? I'm clueless at the moment due to my knowledge of android studio.
Here is my code.

Create a ListView with Text and Favorite Icon based on SQLite Database Data

I want to create a list where the listview will display a textview and an icon for each row. The diagram should be as follows:
Other than that, The data is retrieved from the database. The attribute of "favorite" will be checked first and if true, then the image in listview will be assigned with favorite_icon.png. Else, no icon need to be assigned.
I have been search for the related answer and tutorial, but all of them is too different from what I want and I cannot understand it very much. Hope somebody here can help me. Thank you in advance.

Here is what I got after I have done my Homework
First we set up a custom layout for listview and also for the row of the listview we will use later.
Here is the custom_listview_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/customListView" />
</LinearLayout>
Here is the custom_listview_row.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:minHeight="64dp">
<ImageView
android:id="#+id/clv_imageView"
android:layout_width="32dp"
android:layout_height="32dp"
android:contentDescription="#string/empty"
android:layout_alignParentRight="true"
android:layout_marginLeft="9dp"
android:layout_alignParentTop="true"/>
<TextView
android:id="#+id/clv_textView"
android:layout_width="97dp"
android:layout_height="32dp"
android:layout_alignParentLeft="true"
android:gravity="center_vertical"
android:text="#string/tv_definition"
android:textIsSelectable="true" />
</RelativeLayout>
Then we need to customized how our Custom ArrayAdaptor will look and do.
But before that, make sure you have put your icon in the drawable folder.
Here is my MyPerformanceArrayAdapter.java
import java.util.List;
import android.app.Activity;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
public class MyPerformanceArrayAdapter extends ArrayAdapter<DefinitionObject>{
private List<DefinitionObject> entries;
private Activity activity;
public MyPerformanceArrayAdapter(Activity a, int textViewResourceId, List<DefinitionObject> entries) {
super(a, textViewResourceId, entries);
this.entries = entries;
this.activity = a;
}
public static class ViewHolder{
public TextView item1;
public ImageView item2;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
ViewHolder holder;
if (v == null) {
LayoutInflater vi =
(LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.custom_listview_row, null);
holder = new ViewHolder();
holder.item1 = (TextView) v.findViewById(R.id.clv_textView);
holder.item2 = (ImageView) v.findViewById(R.id.clv_imageView);
v.setTag(holder);
}
else
holder=(ViewHolder)v.getTag();
final DefinitionObject custom = entries.get(position);
if (custom != null) {
holder.item1.setText(custom.getWord());
if(custom.getFav().equalsIgnoreCase("0"))
{
holder.item2.setImageResource(R.drawable.fav);
holder.item2.setVisibility(holder.item2.INVISIBLE);
}
else
{
holder.item2.setImageResource(R.drawable.fav2);
}
}
return v;
}
}
And lastly, here is my Activity to View the ListView using the CustomArrayAdaptor.
import java.util.List;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.ListView;
public class TempCLV extends Activity {
private MySQLiteDefinitionHelper db;
String tblName = "";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.custom_listview_main);
Intent msjIntent = getIntent();
tblName = msjIntent.getStringExtra(WordDefinitionHomeActivity.TABLENAME2);
refresh();
}
public void refresh()
{
db = new MySQLiteDefinitionHelper(this);
final List<DefinitionObject> values = db.getAllWords(tblName);
ListView mylist = (ListView)findViewById(R.id.customListView);
MyPerformanceArrayAdapter adapter = new MyPerformanceArrayAdapter(this, R.id.customListView, values);
mylist.setAdapter(adapter);
}
}

How can i show running app icon in listview using ActivityManager and PackageManager?

I'm trying to making a app that..
-shows currently running app icons in listview

custom ImageViews disapearing from ListAdapter

Ok, my problem is similar to this Background image in ListView entries spontaneously disappearing
but this issue is resolved with using setImageResource on a normal ImageView but I want an animation to exist on all elements of a list, and this can not be done without a custom ImageView class that allows the animation to run. Does anyone know why these images are disappearing after scrolling in the list view and maybe how this can be fixed? Thanks a lot!
Here is my ListAdapter:

Every 5th 'preloader' graphic is still disappearing, but thanks Michele this has helped a lot, and made things cleaner.

Here is a screen shot of what's going on (why is the 5th preload graphic not showing?):
edit ------
Ok, I added the getCount and getItemId overrides but still have the same issues, I figured I would start a project from scratch and try again with just a listView, same issue, I have put up a test project to demonstrate this frustrating issue. In this test I did not even add any data to the adapters, and the animation only works for some of them, just like with my master project.
Thank you so much for your patience and help this far Michele, you have been very awesome.

ListViews are highly optimized Datastructures. You should use ViewHolders to obey the rules of Lists and make the life of the system a bit easier.
When you Scroll a ListView the System caches the Items in Holders for performance.
Read How to load the Listview "smoothly" in android
you can also try to set
yourListView.setDrawingCacheEnabled(false);
edit: ok than try to set your animation with xml
http://developer.android.com/reference/android/graphics/drawable/AnimationDrawable.html
like:
<!-- Animation frames are wheel0.png -- wheel5.png files inside the
res/drawable/ folder -->
<animation-list android:id="selected" android:oneshot="false">
<item android:drawable="#drawable/wheel0" android:duration="50" />
<item android:drawable="#drawable/wheel1" android:duration="50" />
<item android:drawable="#drawable/wheel2" android:duration="50" />
<item android:drawable="#drawable/wheel3" android:duration="50" />
<item android:drawable="#drawable/wheel4" android:duration="50" />
<item android:drawable="#drawable/wheel5" android:duration="50" />
</animation-list>
edit2: please try to implement getCount and getItemId, theres something wrong with the boundarys of your List, maybe android cant find out on with position the list is after scrolling. Oh and can you please test it with random data, not the same item all the way (perhaps some weird hash (default getItemId Implementation?) that is always the same with the same item content).
for example like this:
#Override
public int getCount() {
return <yourdatastructure>.getSize();
}
#Override
public long getItemId(int position) {
return position;
}
