[英]Android onTouchListener
需要帮助,我正准备将android游戏作为我学校的项目。 我尝试使用ontouchListener来碰碰痣。
主要活动
public class First_Stage extends Activity implements OnTouchListener{
private AllViews allViews;
private MoleView moleView;
private PointsView pointsView;
private TimerView timerView;
private StageView stageView;
private Mole mole;
private MoveMole moleMove;
private int points=0;
private StagePoints stagePoints;
private PointsSingelton poin;
private float x,y;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
mole=new Mole();
stageView=new StageView(this);
moleView=new MoleView(this,mole,x,y);
pointsView=new PointsView(this);
timerView=new TimerView(this, "3:33");
allViews=new AllViews(this);
allViews.setViews(stageView, moleView, pointsView, timerView);
setContentView(allViews);
allViews.setOnTouchListener((View.OnTouchListener)this);
}
@Override
public boolean onTouch(View v, MotionEvent event) {
x=event.getX();
y=event.getY();
return true;
}
所有意见班
public class AllViews extends SurfaceView implements SurfaceHolder.Callback, Runnable{
private MoleView moleView;
private PointsView pointsView;
private TimerView timerView;
private StageView mainView;
private float x,y;
private Paint test;
private First_Stage first;
Thread drawThread = new Thread(this);
SurfaceHolder holder;
public AllViews(Context context) {
super(context);
test=new Paint();
first=new First_Stage();
holder= getHolder();
holder.addCallback(this);
}
public void setViews(StageView mainView, MoleView moleView, PointsView pointsView,TimerView timerView)
{
this.mainView = mainView;
this.moleView = moleView;
this.pointsView = pointsView;
this.timerView = timerView;
}
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
mainView.onDraw(canvas);
moleView.onDraw(canvas);
pointsView.onDraw(canvas);
timerView.onDraw(canvas);
test.setColor(Color.BLUE);
canvas.drawCircle(first.getX(), first.getY(), 40, test);
}
@Override
public void run() {
Canvas c;
while (true) {
c = null;
try {
c = holder.lockCanvas(null);
synchronized (holder) {
onDraw(c);
}
} finally {
if (c != null) {
holder.unlockCanvasAndPost(c);
}
}
}
}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
// TODO Auto-generated method stub
}
@Override
public void surfaceCreated(SurfaceHolder holder) {
drawThread.start();
}
我也有班级来骚扰,点数,时间和舞台屏幕。 但我不知道用哪种视图制作触摸监听器。 尝试了一下,我做了一个蓝色的圆圈,并尝试用侦听器事件中的新位置更改了它的位置,但并不缺少。
任何帮助都会很棒。 谢谢,

onTouchListener应该在AllViews类中实现,因为如果在其他视图中实现它,则将获得相对于特定视图的左/上位置的位置。
在AllViews的onDraw中,您可以绘制其余对象
您要在哪种视图中创建onTouchListener
取决于您,但是onTouchListener
是需要实现的接口。 并且在实现后,您将需要正确的方法,在这种情况下,我认为是onTouch()
。 看一下文档
在我看来,您需要让AllViews
知道您从触摸屏上收到了信息。
您可以在AllViews
创建几个属性
private int touchX;
private int touchY;
public void setTouchX(int x) { this.touchX = x; }
public void setTouchY(int y) { this.touchY = y; }
然后在您的onTouch
方法中,在return
语句之前添加以下行:
AllViews.setTouchX(x);
AllViews.setTouchY(y);
最后,在您的onDraw
方法中,进行更改
canvas.drawCircle(first.getX(), first.getY(), 40, test);
至
canvas.drawCircle(this.touchX, this.touchY, 40, test);
