android - populate ListView from my database -

I have read so many posts about how to populate the listview from the database but I just can not do it on my app ! I do not know what is doing wrong. I am very new to programming, so I am not allocating things that I do not understand, but I am trying to learn :)

I add the item to the database without any problem in using this code in the activity:

  string selected stone = (string) stonespinner.getSelectedItem (); String weight = atadvite.gate text (). ToString (); Db.addStone (new MyStonesDatabase (selected stone, weight));   
 I have this:  
  // Add new Stone Zero Adstone (MyStones database database) {SQLiteDatabase db = this.getWritableDatabase (. ); Material values ​​= new material value (); Values.put (KEY_STONE, stone.getStone ()); Values.put (KEY_WEIGHT, stone.getWeight ()); // enter the line DB.inet (TABLE_MYSTONES, zero, value); Db.close (); // database connection termination}   
 I can see that my database is populated by running:  
  log. D. ("Reading:", "Reading All Items .."); & Lt; MyStonesDatabase & gt; Item = db.getAllstones (); (Mattsonsdatabase.cn: item) {string log = "id:" + cn.getID () + ", stone:" + cn.getStone () + ", weight:" + cn.getWeight (); To log the log // write the article ("name:", log); }   
 But when trying to keep a list view to show the database, my app crashes or does not show anything. Handler in my database. I have this in Java:  
  // Obtaining all items from the database Public list & lt; MyStonesDatabase & gt; GetAllstones () {List & lt; MyStonesDatabase & gt; Stone List = New Arrestist & lt; MySpace Database & gt; (); // Choose all the query string selectQuery = "SELECT * FROM" + TABLE_MYSTONES; SQLiteDatabase db = this.getWritableDatabase (); Cursor cursor = db.rawQuery (selectQuery, zero); // Adding looping and list through all the rows if (cursor.movatofst ()) {to {MyStonesDatabase stone = new MyStonesDatabase (); Stone.setID (Integer.parseInt (cursor.getString (0)); Stone.setStone (cursor.getString (1)); Stone.setWeight (cursor.getString (2)); // stone stone link add stone (stone); } While (cursor.movetoonext ()); } // Return Stoneworth return stone; }   
 I do not know what should be included in my activity, which should show list view.  
  Public class increases the list of MySTONS inventory {/ ** is called when activity first created * / @Override Public Zero OnCreate (bundled savedInstanceState) {super.onCreate (savedInstanceState); }   
}  
 Can someone please help me, please leave it to Hehe :) Thanks!   
 
 
 Here's a great article / tutorial that can help you. Viewing your list view is not as easy to do in your activity. You need to create a list of adapters and other things in tutorials, they use hard-coded values ​​in an array. You can try to work it out, then remove the data with the hard code, and you can use the data from your DB.  
 This work is a little easier than you think, but is not too complicated.  
 Hope this helps:
