SurfaceView如何结合Android UI
SurfaceView提供的是直接访问画布进行绘图的机制,在里面创建Android UI是行不通的,不过游戏中经常会用到Andoird UI,这个就需要两者能够很好地结合使用.先需要说明的一点,SurfaceView,ListView以及UI统统都继承了View,要结合它们只能在上层进行操作,具体的说不太清楚,我理解的也不是很透彻,贴下代码吧,无代码无真相http://www.agoit.com/images/smiles/icon_wink.gif:
package com.ray.bubble;
import android.app.Activity;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.RectF;
import android.os.Bundle;
import android.view.SurfaceHolder;
import android.view.SurfaceView;
import android.view.Window;
import android.view.WindowManager;
import android.widget.FrameLayout;
import android.widget.TextView;
public class BubbleExplosion extends Activity {
private FrameLayout frame;
private MyView myView;
private TextView text;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams. FLAG_FULLSCREEN ,
WindowManager.LayoutParams. FLAG_FULLSCREEN);
frame = new FrameLayout(this);
text = new TextView(this);
text.setTextSize(20);
text.setText("lovehui");
text.setHeight(30);
text.setWidth(100);
frame.addView(myView);
frame.addView(text);
setContentView(frame);
}
class MyView extends SurfaceView implements SurfaceHolder.Callback{
SurfaceHolder holder;
public MyView(Context context) {
super(context);
holder = this.getHolder();//获取holder
holder.addCallback(this);
}
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
public void surfaceCreated(SurfaceHolder holder) {
new Thread(new MyThread()).start();
}
public void surfaceDestroyed(SurfaceHolder holder) {
}
//内部类的内部类
class MyThread implements Runnable{
public void run() {
Canvas canvas = holder.lockCanvas(null);//获取画布
Paint mPaint = new Paint();
mPaint.setColor(Color.BLUE);
canvas.drawRect(new RectF(40,60,80,80), mPaint);
holder.unlockCanvasAndPost(canvas);//解锁画布，提交画好的图像
}
}
}
}
