I want to have a screen with snowflakes falling (in the spirit of the
Holiday Season) and the snow building in the bottom of the screen. So
far all I have been able to do is show a lone white dot on the black
screen. What should I do to make another 100 or 1000 of those dots and
make them float down to the bottom of the screen just like real
snowflakes?
import android.app.Activity;
import android.os.Bundle;
import java.util.Random;
public class DroidSnowGlobe extends Activity{
Random generator = new Random();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
snowview sv = new snowview(this);
setContentView(sv);
while (true) {
int x = generator.nextInt(100) +1;
int y = generator.nextInt(100) +1;
sv.changepos(x, y); //Does not work at all
setContentView(sv);
}
}
}
snowview class:
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.drawable.ShapeDrawable;
import android.graphics.drawable.shapes.OvalShape;
import android.view.View;
import java.util.Random;
public class snowview extends View{
Random generator = new Random();
private ShapeDrawable mDrawable;
public snowview(Context context) {
super(context);
int x = generator.nextInt(100) +1;
int y = generator.nextInt(100) +1;
int width = 3;
int height = 3;
mDrawable = new ShapeDrawable(new OvalShape());
mDrawable.getPaint().setColor(Color.WHITE);
mDrawable.setBounds(x, y, x + width, y + height);
}
protected void onDraw(Canvas canvas) {
mDrawable.draw(canvas);
}
public void changepos(int x, int y){
int width = 3;
int height = 3;
mDrawable.setBounds(x, y, x + width, y + height);
}
}
