I have two fragments one with installed apps and one that is blank. Both are listviews. I have a plus sign next to each item in the installed app listview. I am trying to make it so that when the user clicks the plus button. The listview app item goes to the blank fragment.
What I am trying to do is use create a public string array in the activity which is holding the tabs and when I click on the plus button add the packagename to the array.
And then in the blank fragment I am trying to check if it is found in the string array using the index.
In my BlockActivity class with holds the actionbar tabs I made this:
public static List<String> blacklist = new ArrayList<String>();
And here is my blank fragment condition to retrieve the app:
if(!b || !c ) {
if (BlockActivity.blacklist.contains(pi.packageName))
{
packageList1.add(pi);
}
}
Now I think I have to you will have to reference to the position of the item the button was clicked from listview. Doing this, I will probably have to reference a method from my adapter class, but I am not sure how to implement that and the method.
I am trying to follow something similar to this:
Here is my adapter class:
package com.ibc.android.demo.appslist.app;
import android.app.Activity;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.graphics.drawable.Drawable;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageButton;
import android.widget.TextView;
import com.spicycurryman.getdisciplined10.app.R;
import java.util.List;
public class ApkAdapter extends BaseAdapter {
List<PackageInfo> packageList;
Activity context;
PackageManager packageManager;
boolean[] itemChecked;
public ApkAdapter(Activity context, List<PackageInfo> packageList,
PackageManager packageManager) {
super();
this.context = context;
this.packageList = packageList;
this.packageManager = packageManager;
itemChecked = new boolean[packageList.size()];
}
private class ViewHolder {
TextView apkName;
ImageButton ck1;
}
public int getCount() {
return packageList.size();
}
public Object getItem(int position) {
return packageList.get(position);
}
public long getItemId(int position) {
return 0;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
LayoutInflater inflater = context.getLayoutInflater();
if (convertView == null) {
convertView = inflater.inflate(R.layout.installed_apps, null);
holder = new ViewHolder();
holder.apkName = (TextView) convertView
.findViewById(R.id.appname);
holder.ck1 = (ImageButton) convertView
.findViewById(R.id.plus1);
convertView.setTag(holder);
//holder.ck1.setTag(packageList.get(position));
} else {
holder = (ViewHolder) convertView.getTag();
}
// ViewHolder holder = (ViewHolder) convertView.getTag();
PackageInfo packageInfo = (PackageInfo) getItem(position);
Drawable appIcon = packageManager
.getApplicationIcon(packageInfo.applicationInfo);
String appName = packageManager.getApplicationLabel(
packageInfo.applicationInfo).toString();
appIcon.setBounds(0, 0, 75, 75);
holder.apkName.setCompoundDrawables(appIcon, null, null, null);
holder.apkName.setCompoundDrawablePadding(15);
holder.apkName.setText(appName);
// I guess the onClickListener would go here??!?!? Not sure how to do it in this case and reference it to the Fragment??
return convertView;
}
}
And here is my blank fragment:
package com.spicycurryman.getdisciplined10.app;
import android.content.Context;
import android.content.pm.ApplicationInfo;
import android.content.pm.PackageInfo;
import android.content.pm.PackageItemInfo;

import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import java.util.ArrayList;
import java.util.Collections;
import java.util.Comparator;
import java.util.List;
public class CustomList_Activity extends Fragment
implements OnItemClickListener {
PackageManager packageManager;
ListView apkList;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setHasOptionsMenu(true);
View rootView = inflater.inflate(R.layout.user_installed, container, false);
packageManager = getActivity().getPackageManager();
/*To filter out System apps*/
apkList = (ListView) rootView.findViewById(R.id.applist);
new LoadApplications(getActivity().getApplicationContext()).execute();
return rootView;
}
/**
* Return whether the given PackageInfo represents a system package or not.
* User-installed packages (Market or otherwise) should not be denoted as

*
* @param pkgInfo
* @return boolean
*/
private boolean isSystemPackage(PackageInfo pkgInfo) {
return ((pkgInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) ? true
: false;
}
private boolean isSystemPackage1(PackageInfo pkgInfo) {
return ((pkgInfo.applicationInfo.flags & ApplicationInfo.FLAG_UPDATED_SYSTEM_APP) != 0) ? false
: true;
}
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
}
private class LoadApplications extends AsyncTask<Void, Void, Void> {
List<PackageInfo> packageList1 = new ArrayList<PackageInfo>();
public LoadApplications(Context context){
Context mContext = context;
}
@Override
protected Void doInBackground(Void... params) {
List<PackageInfo> packageList = packageManager
.getInstalledPackages(PackageManager.GET_PERMISSIONS);
for(PackageInfo pi : packageList) {
boolean b = isSystemPackage(pi);
boolean c = isSystemPackage1(pi);
if(!b || !c ) {
if (BlockActivity.blacklist.contains(pi.packageName))
{
packageList1.add(pi);
}
}
}
//sort by application name
final PackageItemInfo.DisplayNameComparator comparator = new PackageItemInfo.DisplayNameComparator(packageManager);
Collections.sort(packageList1, new Comparator<PackageInfo>() {
@Override
public int compare(PackageInfo lhs, PackageInfo rhs) {
return comparator.compare(lhs.applicationInfo, rhs.applicationInfo);
}
});
return null;
}
@Override
protected void onCancelled() {
super.onCancelled();
}
@Override
protected void onProgressUpdate(Void... values) {
super.onProgressUpdate(values);
}
}
}
