I use SurfaceView for my game, tried normal View first but that was to
slow.
Problem is, it still is. The redrawing just isn't anywhere fast enough
for a game. So unless it is a lot faster on the real phone this won't
cut it at all.
Is it necessary to use OpenGL for games?
package com.android.shmup;
import android.app.Activity;
import android.content.Context;
import android.graphics.*;
import android.os.Bundle;
import android.view.View;
import android.view.KeyEvent;
public class Shmup extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(new GameView(this));
}
private static class GameView extends View {
private Paint mPaint = new Paint();
private int x;
private int y;
public GameView(Context context) {
super(context);
x = 135;
y = 303;
setFocusable(true);
requestFocus();
}
@Override
protected void onDraw(Canvas canvas) {
Paint paint = mPaint;
canvas.translate(10, 10);
canvas.drawColor(Color.rgb(184,134,11));
paint.setColor(Color.rgb(107,142,35));
paint.setStrokeWidth(1);
canvas.drawRect(x, y, x+30, y+7, paint);
canvas.drawRect(x+10, y+7, x+20, y+27, paint);
canvas.drawRect(x+5, y+27, x+25, y+32, paint);
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if (keyCode == KeyEvent.KEYCODE_DPAD_UP) {
y -= 3;
invalidate();
} else if (keyCode == KeyEvent.KEYCODE_DPAD_LEFT) {
x -= 3;
invalidate();
} else if (keyCode == KeyEvent.KEYCODE_DPAD_DOWN) {
y += 3;
invalidate();
} else if (keyCode == KeyEvent.KEYCODE_DPAD_RIGHT) {
x += 3;
invalidate();
}
return true;
}
}
}
