Pressing Search button clears all items / models on List View

My ListView works fine on start up. The problem is that whenever I click the search Button which triggers the search view, all items on my ListView disappears. Even after I clear the text field on my searchview, my ListView still is on a state where it is empty.

How to convert a row of a sqLite db into an arrayList and then choose a random element of the list?

I am currently working on an app, the final goal of it is that you click a button and it will display a random challenge that is stored in the sqlLite DB.
I can't manage to take a random row of it, even with all the tutorials and the posts on StackOverflow talking about it, maybe my current level and knowledge are to small to make it work. Perhaps the fact that I use it in a Fragment can make it even harder.
Because I can't manage to take directly a random row in my DB, I thought about using an arrayList to store the string stored in the column "Gage" of all the rows of my db, and then take a random element of this arrayList.
So, if someone knows what is wrong, please help me.

How about creating the random number before executing the SQL command - Then when you use your SELECT statement you could include the random number variable as the ID to query?

Fetching values from Cursor but Application Crashes

I am trying to fetch values from the database when I click on the view button which is another activity for navigation when I click on the view all button the CustodianViewActivity is triggered to display all the values from the database on a list view but in my case the application crashes every time I try to view the data from the database. Am not sure where I am going wrong.

Creating a contextual menu when long pressing item in android

I am creating a checklist and it allows the user to add new items to the list, I am trying to allow the user to delete an item when they want to. So I am creating a contextual menu using this that comes us when the user long-presses an item in the list. Right now, it recognizes the long-press but nothing happens, so the contextual menu doesn't appear.
Here is my activity page: (ViewTask.java)

Thanks you for the responses, now I cannot get the item to actually be deleted.
here is my database helper page:(TaskerDbHelper.java)
package com.example.androidhive;
import java.util.ArrayList;
import java.util.List;
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;

public class TaskerDbHelper extends SQLiteOpenHelper{
private static final int DATABASE_VERSION = 1;
// Database Name
private static final String DATABASE_NAME = "taskerManager";
// tasks table name
private static final String TABLE_TASKS = "tasks";
// tasks Table Columns names
private static final String KEY_ID = "id";
private static final String KEY_TASKNAME = "taskName";
private static final String KEY_STATUS = "status";
public TaskerDbHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
String sql = "CREATE TABLE IF NOT EXISTS " + TABLE_TASKS + " ( "

db.execSQL(sql);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldV, int newV) {
// Drop older table if existed
db.execSQL("DROP TABLE IF EXISTS " + TABLE_TASKS);
// Create tables again
onCreate(db);
}
public void addTask(Task task) {
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(KEY_TASKNAME, task.getTaskName()); // task name
// status of task- can be 0 for not done and 1 for done
values.put(KEY_STATUS, task.getStatus());
// Inserting Row
db.insert(TABLE_TASKS, null, values);
db.close(); // Closing database connection
}
public boolean deleteTask(long task)
{
SQLiteDatabase db = this.getWritableDatabase();
return db.delete(TABLE_TASKS, KEY_TASKNAME + "=" + task, null) > 0;
}
public List<Task> getAllTasks() {
List<Task> taskList = new ArrayList<Task>();
// Select All Query
String selectQuery = "SELECT * FROM " + TABLE_TASKS;
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
// looping through all rows and adding to list
if (cursor.moveToFirst()) {
do {
Task task = new Task();
task.setId(cursor.getInt(0));
task.setTaskName(cursor.getString(1));
task.setStatus(cursor.getInt(2));
// Adding contact to list
taskList.add(task);
} while (cursor.moveToNext());
}
// return task list
return taskList;
}
public void updateTask(Task task) {
// updating row
SQLiteDatabase db = this.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(KEY_TASKNAME, task.getTaskName());
values.put(KEY_STATUS, task.getStatus());
db.update(TABLE_TASKS, values, KEY_ID + " = ?",new String[] {String.valueOf(task.getId())});
db.close();
}
}
That file above contains my deleteTask().

I don't see registerForContextMenu() anywhere. This is necessary for the list to actually know that it has a contextmenu.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_task);
db = new TaskerDbHelper(this);
list = db.getAllTasks();
adapt = new MyAdapter(this, R.layout.list_inner_view, list);
ListView listTask = (ListView) findViewById(R.id.listView1);
listTask.setAdapter(adapt);
registerForContextMenu(listTask); // <-- Register!
}
In addition you should put a String value in your menu xml file. Obviously it is better to refer to your string xml file for the actual string.
<item
android:id="#+id/Edit_Task"
android:title="Edit">
</item>
<item
android:id="#+id/Delete_Task"
android:title="Delete">
</item>
Concerning the delete task:
To delete your task from the sql database you need some kind of identifier. As far as I can tell, you have only a task name and a status integer. If you allow tasks to have the same name, this cannot be used as an unique identifier. Perhaps you should add that to your Task class. You can then use this to find and remove the specific task in your database. (Your info.id will not work, because it is merely the identifier of the view) You can use info.position to retrieve the position of the Task in taskList, or more specifically, the current list in the adapter.
case R.id.Delete_Task:
Task task = list.get(info.position);
if (db.deleteTask(task.getUniqueIdentifier())) { // <-- Determine the unique id
list.Remove(info.position);
listTask.invalidate();
return true;
}
return false;
I'm not sure whether invalidate() will do the trick. But give it a try. You could also give the adapter the new list and call notifyDataSetChanged() as you do for the addTaskNow().

You need to add this line to your onCreate method
registerForContextMenu(listTask);
Your onCreateContextMenu() needs to look like this
#Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
if (v.getId() == R.id.listView1) { //YOUR VIEW THAT IS ATTACHED TO LISTASK
AdapterView.AdapterContextMenuInfo info = (AdapterContextMenuInfo) menuInfo;
menu.setHeaderTitle("Options");
String[] menuItems = { "Option1", "Option2", "Option3", "Option4"} };
for (int i = 0; i < menuItems.length; i++) {
menu.add(Menu.NONE, i, i, menuItems[i]);
}
}
}
and finally your OnContextMenuItemSelected()
#Override
public boolean onContextItemSelected(android.view.MenuItem item) {
AdapterView.AdapterContextMenuInfo info = (AdapterContextMenuInfo) item
.getMenuInfo();
menuItemIndex = item.getItemId();
String[] menuItems = { "Option 1, Option 2, Option 3" };
String menuItemName = menuItems[menuItemIndex];
return true;
}
