Java中View游戏开发框架

java中游戏开发引擎View比较适合被动触发的游戏，不能使用于那种对战的游戏

Game01Activity.java  这里是调用的activity

package cn.sun.syspro;

import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;

public class Game01Activity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       // setContentView(R.layout.main);
        //隐藏定格
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        this.getWindow()
        .setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        setContentView(new Myview(this));
    }
}

　　Myview.java

package cn.sun.syspro;

import android.R.style;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.view.KeyEvent;
import android.view.MotionEvent;
import android.view.View;

public class Myview extends View{
/**
 * 重写父类构造函数
 * @param context
 */
	private int x = 200,y = 200;
	public Myview(Context context) {
		super(context);
		setFocusable(true);
		// TODO Auto-generated constructor stub
	}
	/**
	 * 重写绘图函数
	 */
	@Override
	protected void onDraw(Canvas canvas){
		//创建一个画笔
		Paint paint = new Paint();
		//设置画笔的颜色
		paint.setColor(Color.BLACK);
		//绘制文本
		canvas.drawRGB(250, 224, 240);
		canvas.drawText("Hello Sun",this.x,this.y, paint);		
		super.onDraw(canvas);
	}
	/**
	 * 重写按下事件
	 */
	@Override
	public boolean onKeyDown(int keyCode,KeyEvent event){
		if(keyCode == event.KEYCODE_DPAD_UP){
			this.y-=2;
		}else if(keyCode == event.KEYCODE_DPAD_DOWN){
			this.y+=2;
		}else if(keyCode == event.KEYCODE_DPAD_LEFT){
			this.x-=2;
		}else if(keyCode == event.KEYCODE_DPAD_RIGHT){
			this.x+=2;
		}
		invalidate();
		return super.onKeyDown(keyCode, event);
	}
	/**
	 * 重写按键弹起事件
	 */
	@Override
	public boolean onKeyUp(int keyCode,KeyEvent event){
		if(keyCode == event.KEYCODE_DPAD_UP){
			this.y-=2;
		}else if(keyCode == event.KEYCODE_DPAD_DOWN){
			this.y+=2;
		}else if(keyCode == event.KEYCODE_DPAD_LEFT){
			this.x-=2;
		}else if(keyCode == event.KEYCODE_DPAD_RIGHT){
			this.x+=2;
		}
		invalidate();
		return super.onKeyUp(keyCode, event);
	}
	/**
	 * 重写触屏事件函数
	 */
	@Override
	public boolean onTouchEvent(MotionEvent event){
		int t_x = (int) event.getX();
		int t_y = (int) event.getY();
		if(event.getAction() == MotionEvent.ACTION_DOWN){
			this.x = t_x;
			this.y = t_y;
		}else if(event.getAction() == MotionEvent.ACTION_MOVE){
			this.x = t_x;
			this.y = t_y;			
		}else if(event.getAction() == MotionEvent.ACTION_UP){
			this.x = t_x;
			this.y = t_y;			
		}
		invalidate();
		return super.onTouchEvent(event);
	}
