Question

我正致力于信道,并能够完成二分之一的图形部分,并在二字(如旧电话)上放置一些 app,现在我想确定用户已经触及哪些问题。我已在感动的听众中执行这一守则:

public class CanvasDemActivity extends Activity {

Bitmap mLight,mDial,mBrowser,mCamera,mMessage,mDialer,mHome,mLock;
float angle;
ArrayList<Double> mCurrentAngleArray;
ArrayList<PointF> mArray; 
ArrayList<Bitmap> mBitmapArray;
PointF p1,p2,p3,p4,p5;
String mTIme;
Date date;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    // making it full screen
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
    Dialer view = new Dialer(this);
    setContentView(view);

    view.setOnTouchListener(new OnTouchListener() {

        @Override
        public boolean onTouch(View v, MotionEvent event) {

            int action = event.getAction();

if(action == MotionEvent.ACTION_DOWN) {
PointF p = new PointF();
   p.x = event.getX(); p.y = event.getY();

  for(int i=0;i<5;i++) {
if (p.x >= mArray.get(i).x && p.x < (mArray.get(i).x + mBitmapArray.get(i).getWidth())
        && p.y >= mArray.get(i).y && p.y < (mArray.get(i).y + mBitmapArray.get(i).getHeight())) {
    System.out.println("presssed on icon " + i);

当p.x和p.y是用户触动的坐标,而mArray是我放置轨道图的坐标,而mBitmapArray是我储存的轨道图的阵列。

The problem is that even though I have written the code correctly, I am unable to get into the "if" condition when I am pressing browser and dialer icons.
I have tested the same code in a sample app and it works fine.
Can you please tell me what s the problem?
