getUnicodeChar() in android mode?

anthony20

Hello, I want to get the value of the keypresses with getUnicodeChar()

    import android.view.KeyEvent;
    KeyEvent event;
    int unicodeChar=0;

    void draw()
    {
      if(mousePressed == true){showVirtualKeyboard();delay(888);} 
      unicodeChar = event.getUnicodeChar();
      text(unicodeChar , 22, 22);
      delay(1000);
    }

public void showVirtualKeyboard() { InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0); }

This code does not work, that I can do?

thanks

@anthony20=== try this

        import android.view.KeyEvent;
        KeyEvent event;
        int unicodeChar;
        import android.content.Context;
        import android.text.InputType;
        import android.view.KeyEvent;
        import android.view.inputmethod.EditorInfo;
        import android.view.inputmethod.InputMethodManager;
        import android.widget.EditText;
        import android.widget.TextView;
        import android.widget.TextView.OnEditorActionListener;
        InputMethodManager imm;

        void setup(){

        }

        void draw()
        {
          if(mousePressed == true){
            showVirtualKeyboard();

        } 

        }

        @Override
            public boolean dispatchKeyEvent(KeyEvent event) {  
                 unicodeChar = event.getUnicodeChar();
                 println(unicodeChar);
                return super.dispatchKeyEvent(event);
            };

        public void showVirtualKeyboard() { 
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE); 
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0); 

        };

--------or (more simple to understand) == (anyway the problem is that in your drawcode the event is always null and so you cannot call event.getUnicodeChar())

    public boolean onKeyUp(int keyCode, KeyEvent event) {
     unicodeChar = event.getUnicodeChar();
          println("unicode" + unicodeChar);
                return super.onKeyUp(keyCode, event);
        }

Hi, @akenaton Thanks for help me,

I don´t understand...

This code work well in tablet and samsung galaxy ace. But in samsung galaxy mini i only can read numeric chars.

When I press the other characters nothing happens, it is as if the keyboard not connected to event, and the data Char is lost.

akenaton

what running? 2.3................................4.4???

anthony20

is 4.0.3

akenaton

same result with my code(try the twos, dispatchevent && onKeyUp())???

akenaton

same result with my code(try the twos, dispatchevent && onKeyUp())??? What returns the println() as for me i have tested on 2 phones and it works...

Hi @Akenaton, thanks for the help me,

I really do not understand why this error happens.

Anyway, finally I was able to successfully implement the apwidgets library.

So I'm going to rule out using getUnicodeChar ()

akenaton

yet i am curious to know what returns println()

anthony20

I do it: text(int(unicodeChar),random(800),random(380)); some keys, especially numbers give correct values. However most of letters and other keys are not displayed when pressed, as if these characters were not prosecuted.

println returns nothing,

The strange thing is that the code works other devices with apparent normality.
