Android :: Path To Array / Read Points On Path?

Jul 5, 2010

Is there a way to read the points created when drawing a path? It seems silly to me that a path cannot be readable.Or is it just better to manually write the current finger position to an array?

Android :: Custom View Not Appearing?

When I comment out setContentView(boardView); in my Game.java my custom view in BoardView works fine and displays everything nicely... but onSizeChanged never gets called in BoardView.java... so I can't read the device width and height at runtime. If I leave setContentView uncommented onSizeChanged works... but the screen is blank! I want to be able to read the screen width and height at runtime and set the sizes of my ImageViews at creation so they are the optimal size.

Android :: Get File Path With URI

I am launching an image picker (from the gallery) and my code crashes every single time. I tried to get some help in another post, but people quit responding to the post. Please help. When I do a debug, it tells me this (there are TONS of errors, but these looked the most important - also, I changed the "com.app.name/com.app.name.activity" for privacy reasons):

Here is the code that invokes the activity, follwed by the code that is invoked after the activity has finished:

Android :: How To Get A Path To Resources

Sep 10, 2010

I'd like to use the RandomAccessFile class to access a file that ships with my application. However, that class only accepts a String which is the path to the file. If I place my file somewhere like the assets directory, how do I construct a path to that file? I know I can use the getAssets methods to read up resources, but those only return InputStreams which cannot be seeked.

Android :: Stop Activity Appearing When An App Is Reopened?

Apr 17, 2010

In Android, I have some code to check whether the user has GPS switched on, and launch the Settings for them to turn it on if they don't.However, I'm finding that if the user opens the Settings, turns GPS on, then carries on using the app as normal, there is an odd problem. Often, when the user reopens the app, the Settings are at the front. How can I set them so they don't keep reappearing?I wonder if I should be using the CLEAR_TOP flag or something similar.I've tried looking at the docs for the Activity flags but find them a bit confusing.

Android :: Following Straight Line (via Path)?

Nov 4, 2010

I'm working on a game which will use projectiles. So I've made a Projectile class and a new instance is created when the user touches the screen:

@Override
public boolean onTouch(View v, MotionEvent e){
float touch_x = e.getX();
float touch_y = e.getY();
new Projectile(touch_x, touch_y);

And the Projectile class:
public class Projectile{
float target_x;
float target_y;
Path line;

public Projectile(float x, float y)
target_x = x;
target_y = y;
line = new Path();
line.moveTo(MyGame.mPlayerXPos, MyGame.mPlayerYPos);
line.lineTo(target_x, target_y);

So this makes a Path with 2 points, the player's position and and touch coords. My question is - How can you access points on this line? For example, if I wanted to get the x,y coords of the Projectile at the half point of the line, or the point the Projectile would be at after 100 ticks (moving at a speed of X pixels/tick)? I also need the Projectile to continue moving after it reaches the final point. Do I need to use line.addPath(line) to keep extending the Path?

I managed to get the Projectiles moving in a straight line, but they're going in strange directions. I had to fudge some code up:
private void moveProjectiles(){
ListIterator<Projectile> it = Registry.proj.listIterator();
while ( it.hasNext() ){
Projectile p = it.next();
p.TimeAlive++;

double dist = p.TimeAlive * p.Speed;
float dx = (float) (Math.cos(p.Angle) * dist);
float dy = (float) (Math.sin(p.Angle) * dist);
p.xPos += dx;
p.yPos += -dy;

The Angle must be the problem. I'm using this method, which works perfectly:
private double getDegreesFromTouchEvent(float x, float y){
double delta_x = x - mCanvasWidth/2;
double delta_y = mCanvasHeight/2 - y;
double radians = Math.atan2(delta_y, delta_x);
return Math.toDegrees(radians);
However, it returns 0-180 for touches above the center of the screen, and 0 to -180 for touches below.
