import android.view.MotionEvent?

infsys

I have the ketai library and wrote this: import ketai.ui.*;. Then this: import android.view.MotionEvent but the console prints me: No library found for android.view. The label above the console prints me:"The type android.view.MotionEvent cannot be resolved. It indirectly referenced from required .class files". How can I fix this? Do I have to download something? If I have to download, how can I download it?

@infsys== can you send your code??? - There is some problem with your import but i have to see...

Code from the book Rapid Android Development by Daniel Sauter that I used for learning:

    import ketai.ui.*;
    import android.view.MotionEvent;

    KetaiGesture gesture;
    float rectSize = 100;
    float rectAngle = 0;
    int x, y;

    color c = color(255);
    color bg = color(78, 93, 75);

    void setup() {
     orientation(LANDSCAPE);
     gesture = new KetaiGesture(this);

    textSize(32);
    textAlign(CENTER, BOTTOM);
    rectMode(CENTER);
    noStroke();

    x = width/2;
    y = height/2;
    }

    void draw() {
     background(bg);
    pushMatrix();
    translate(x, y);
    rotate(rectAngle);
    fill(c);
    rect(0, 0, rectSize, rectSize);
    popMatrix();
    }

    void onTap(float x, float y) {
      text("SINGLE", x, y-10);
      println("SINGLE:" + x + "," + y);
    }

    void onDoubleTap(float x, float Y) {
      text("DOUBLE", x, y-10);
      println("DOUBLE:" + x + "," + y);
      if (rectSize > 100)
        rectSize = 100;
        else
        rectSize = height - 100;
    }

    void onLongPress(float x, float y) {
      text("LONG", x, y - 10);
      println("LONG:" + x + "," + y);

      c = color(random(255), random(255), random(255));
    }

    void onFlick(float x, float y, float px, float py) {
      text("FLICK", X, Y-10);
      println("FLICK:" + x + "," + y + "," + v);

      bg = color(random(255), random(255), random(255));
    }

    void onPinch(float x, float y, float d) {
      rectSize = constrain(rectSize+d, 10, 500);
      println("PINCH:" + x + "," + y + "," + d);
    }

    void onRotate(float x, float y, float angle) {
      rectAngle += angle;
      println("ROTATE:" + angle);
    }

    void mouseDragged() {
      if (abs(mouseX - x) < rectSize/5 && abs(mouseY - y) < rectSize/2) {
        if (abs(mouseX - pmouseX) < rectSize/2)
          x += mouseX - pmouseX;
        if (abs(mouseY - pmouseY) < rectSize/2)
          y += mouseY - pmouseY;
      }
    }

    public boolean surfaceTouchEvent(MotionEvent event) {
      // Call to keep mouseX and mouseY constants updated
      super.surfaceTouchEvent(event);
      // Forward events
      return gesture.surfaceTouchEvent(event);
    }

Thanks. Paste, select, then c button. I edited the code. :D

On Android Mode the label says "Error from inside the Android tools, check the console."

@infsys:::

tested the code --- not any problems with import ----your error is described in the console message::

a) what is "X", what is "Y"; change X for x and Y to y

b) "v" is never typed or defined; try "float v = px -py" or something like this ( i cannot guess because i know "onFling()" bt never seen onFlick(); with onFling() px && py are velocity for the gesture:: could it be that "v" is here for "velocity"???

after that no more errors for me...

--- it seems also that one icon is not present in your android mode folder but that is not very important for the moment, probably the laucher icon

infsys

Yes. X to x, Y to y and an additional parameter float v for velocity. I never thought those were the errors. I have to be careful with the syntax. I thought it was the import. There is no yellow line indicating the errors in Android Mode. Thanks. This code will be helpful for the games: for ex. I was using mouseClicked() but now I have real options for Android mode.

@infsys: forget on mousePresssed() & so on:: you are on a smartphone && there are a lot of gestures (more than in your code)... happy to help.
