Android Module Wizard

[Leledumbo]

@jmpessoa, I get the attached image (that "read error" dialog) everytime I close lazarus with lazandroidmodulewizard project opened. It's not a problem (I'm closing the IDE after all), but it's annoying.

This is what the log says:

Code: [Select]

NOTE: Window with stalled focus found!, faking focus-out event

Yes,  you're right!  I also noticed that here in my system [Win] ... I'll try find fix this error...

Thank you!

[Leledumbo]

One more thing, Lazarus freezes when I use Run->[Lamw] Build apk and run. It freezes when running adb with no emulator/real device running, my guess is that the external tool is not executed asynchronously. Tools that I add to Configure External Tools seem to execute asynchronously, though. Very weird.

[A.S.]

Leledumbo, Run->[Lamw] Build apk and run uses external tools for building/installing/running purposes. But it also determines connected devices, and this check is not asynchronous.

[A.S.]

Yes,  you're right!  I also noticed that here in my system [Win] ... I'll try find fix this error...

Thank you!

Please check. It seems, I fixed it.

[jmpessoa]

@ A.S.

Please check. It seems, I fixed it.

Yes, now it's  ok!

Thank You!

And now some suggestions, requests and bugs:

• Add the OnBack Event In jCustomDialog
  
• The function JNIPrompt is not fired when a form is reactivated trough a Back in a second form, solution could be to add an OnComingBack event to jForm, or firing JNIPrompt event on coming back. At this time data displayed cannot be refreshed in automatic on coming back to first form
  
• The jContextMenu cannot open a form
  
• When a jContextMenu is linked to a jListView would very helpful that the Caption of the Item clicked where accessible or passed. My need is to edit or delete the record associated with the item clicked
  
• jListView is lacking in configurability in order to display many columns of data. What do you think about adding Columns or  something like Tab to jListView?
  
• Add an onClick event to jEditText, to make it possible, i.e., to open in automatic a jDatePickerDialog
  
• Add an itxCurrency mask for jEditText that admits dot and comma with numbers together, or add dot and comma to itxNumber
  

Last request is partially resolved modifying in Controls.java (line 1436) :

Code: [Select]

        if(str.equals("NUMBER")) {
            this.setInputType(android.text.InputType.TYPE_CLASS_NUMBER);
        }
with
        if(str.equals("NUMBER")) {
            this.setInputType(InputType.TYPE_CLASS_NUMBER| InputType.TYPE_NUMBER_FLAG_DECIMAL|
                     InputType.TYPE_NUMBER_FLAG_SIGNED);
       }

that permits input of numbers [0..9], a minus sign prepended and a singular punctuation sign (only point, not comma)

Best regards

For my purpose I need the Id of last inserted row, but my effort are unsuccessful.

I tried to add this method in Controls.java, related to class jSqliteCursor:

Code: [Select]

public long GetLastId() {
                if (this.cursor != null) {
                        int index = 0;
                        index = this.cursor.getColumnIndex("ROWID");
                        this.MoveToLast();
                        return this.GetValueAsLong(index);
        }
        else{
                return -1;
        }
}

this in Laz_and_controls:

Code: [Select]

function jSqliteCursor.GetLastId: integer;
begin
   if not FInitialized  then Exit;
   Result:= integer(jSqliteCursor_GetLastId(FjEnv, FjObject ));
end;     

and this in And_jni_Bridge:

Code: [Select]

Function jSqliteCursor_GetLastId(env:PJNIEnv;  SqliteCursor: jObject): integer;
var
 _jMethod : jMethodID = nil;
 cls: jClass;
begin
 cls := env^.GetObjectClass(env, SqliteCursor);
  _jMethod:= env^.GetMethodID(env, cls, 'GetLastId', '()I');
 Result := integer(env^.CallLongMethod(env,SqliteCursor,_jMethod));
 env^.DeleteLocalRef(env, cls);
end;

and the log report:

I/dalvikvm( 4112): java.lang.NoSuchMethodError: no method with name='GetLastId' signature='()I' in class Lcom/suevoz/borsa/jSqliteCursor;

so, where is the error? Can you help me?

thank you!

[jmpessoa]

@renabor

OK, java/JNI 'long' signature is "J", then

Code: [Select]

_jMethod:= env^.GetMethodID(env, cls, 'GetLastId', '()I');

change to:

Code: [Select]

_jMethod:= env^.GetMethodID(env, cls, 'GetLastId', '()J');


[renabor]

@renabor

OK, java/JNI 'long' signature is "J", then

Code: [Select]

_jMethod:= env^.GetMethodID(env, cls, 'GetLastId', '()I');

change to:

Code: [Select]

_jMethod:= env^.GetMethodID(env, cls, 'GetLastId', '()J');


Now the error is:

JNI WARNING: expected return type 'I'

 

[jmpessoa]

Ok,  change all your pascal function result "integer" to int64 ....

How to create an applicaiton that can connect to a database on free hosting, read datas in database and save from tstringlist ? (theory all them is text only). Seems your demos doesn't mention about this.
thanks

Thanks to All and special thanks to @renabor !!

Thank you very much for all!

I've tried improvements and are all precious!
jContactManager is a must, although I have not tried it so much, I'm working on another project now.

the OnBackKeyPressed in CustomDialog property is great, but break the propagation of Event for soft backkey and del key, here an amended version that handle both soft and hard backkey press:

Code: [Select]

line ~ 10069 in Controls.java

mDialog.setOnKeyListener(new Dialog.OnKeyListener() {
@Override
  public  boolean onKey(DialogInterface arg0, int keyCode, KeyEvent event) {
     if (event.getAction() == KeyEvent.ACTION_UP) {
        if (keyCode == KeyEvent.KEYCODE_BACK) {
             controls.pOnCustomDialogBackKeyPressed(pascalObj, mTitle);
             if (mDialog != null) mDialog.dismiss();
             return false;
        } else if (keyCode == KeyEvent.KEYCODE_ENTER) {
            InputMethodManager imm = (InputMethodManager) controls.activity.getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(getWindowToken(), 0);
            controls.pOnEnter(pascalObj);
            return true;
        }
     }
     return false;
   }
});

Finally I've found a solution for my problem in obtaining the item index clicked out of jListView, here the code that add a listener to OnItemLongClick Event and add the property ItemIndex to jListView:

Code: [Select]

----- in  Laz_And_Controls.pas
line 1040
    function GetItemIndex: integer;
line 1083
    property ItemIndex: integer read GetItemIndex;
line 5120
    function jListView.GetItemIndex: integer;
    begin
      Result:= Self.Items.Count;
      if FInitialized then
        Result:= jListView_GetItemIndex(FjEnv, FjObject );
    end;

----- in  And_jni_Bridge.pas
line 485
  function jListView_GetItemIndex(env:PJNIEnv; ListView : jObject): integer;
line 3915
  function jListView_GetItemIndex(env:PJNIEnv;  ListView : jObject): integer;
  var
    _jMethod : jMethodID = nil;
    cls: jClass;
  begin
    cls := env^.GetObjectClass(env, ListView);
    _jMethod:= env^.GetMethodID(env, cls, 'GetItemIndex', '()I');
    Result:= env^.CallIntMethod(env,ListView,_jMethod);
    env^.DeleteLocalRef(env, cls);
  end;

------- in Controls.java
line 2785
  int itemIndex = -1;
line ~ 2887 
  itemIndex = position;
line ~ 2892
  onItemLongClickListener = new OnItemLongClickListener() {
    public boolean onItemLongClick(AdapterView<?> parent, View v, int position, long id) {
      itemIndex = position;
      return false;
    }
  };
setOnItemLongClickListener(onItemLongClickListener);
line 2949
  public int GetItemIndex() {
    return itemIndex;
  }

Now I'm in trouble with jListView adapter, I'm trying to adapt this example

http://www.codelearn.org/android-tutorial/android-listview

any idea is really appreciated

[jmpessoa]

@renabor,

....I'm trying to adapt this example http://www.codelearn.org/android-tutorial/android-listview

The  jListView already support this possibility!

try this properties: widgetItem, widgetText, imageItem, ItemLayout,
 textDecoreted and textSizeDecoreted ...

Thank You!
