android 触摸人体图像检测 body 部位。我应该使用什么布局元素？

Question

在下图中，我想检测触摸事件发生在人体的哪个部位。我的想法是拥有一个 GridView 并确定发生触摸事件的人体位置。不过，GridView 似乎有点矫枉过正。使用不同的布局会是更好的方法吗？

 gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
                BodyImage item = (BodyImage) parent.getItemAtPosition(position);
                switch (position) {
                    case 0:

                        // code for head

                        break;
                    case 1:
                        // code for nose 
                    case 2:
                        // code for n-human part

Answer 1

首先感谢 Kris Larson 的上述回答。这个想法是叠加这里看到的两个图像 Images to be superposed in the Fragment并隐藏具有颜色的图像。右边的图像使用开源 Gimp 着色 GIMP

然后在 FrameLayout 上我动态添加了两个图像:

/**
 * A Fragment that launches Draw
 */
public static class DrawSectionFragment extends Fragment {

    public static final String ARG_SECTION_NUMBER = "section_number";
    boolean touching = false;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        ........

        View rootView = inflater.inflate(R.layout.image_superposed, container, false);
      //  View rootView = inflater.inflate(R.layout.image_superposed, container);
        final ImageView iv1 = (ImageView) rootView.findViewById(R.id.imgSecond);
        iv1.setImageDrawable(getResources().getDrawable(R.drawable.twocolor1));
        final Bitmap bitmap = ((BitmapDrawable)iv1.getDrawable()).getBitmap();

        iv1.setOnTouchListener(new View.OnTouchListener(){
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                CxMediaPlayer mxMediaPlayer;
                mxMediaPlayer = new CxMediaPlayer(getActivity().getBaseContext());
                switch (event.getAction()) {

                    case MotionEvent.ACTION_DOWN:
                        // TODO Auto-generated method stub
                        touching = true;
                        Matrix inverse = new Matrix();
                        iv1.getImageMatrix().invert(inverse);
                        float[] touchPoint = new float[]{event.getX(), event.getY()};
                        inverse.mapPoints(touchPoint);
                        int xCoord = Integer.valueOf((int) touchPoint[0]);
                        int yCoord = Integer.valueOf((int) touchPoint[1]);

                        int pixel = bitmap.getPixel(xCoord, yCoord);

                        int redValue = Color.red(pixel);
                        int blueValue = Color.blue(pixel);
                        int greenValue = Color.green(pixel);

                        if (pixel == Color.CYAN) {
                            //mxMediaPlayer = new CxMediaPlayer(getActivity().getBaseContext());
                            mxMediaPlayer.playShortResource(getActivity().getBaseContext(), 1) ;
                        }
                        if (pixel == Color.YELLOW) {

                            mxMediaPlayer.playShortResource(getActivity().getBaseContext(), 2) ;
                        }
                        if (pixel == Color.rgb(0,0,255)) {
                            CxMediaPlayer mxMediaPlayer1 = new CxMediaPlayer(getActivity().getBaseContext());
                            mxMediaPlayer1.playShortResource(getActivity().getBaseContext(), 2) ;
                        }

                        break;
                    case MotionEvent.ACTION_CANCEL:
                    case MotionEvent.ACTION_UP:
                        touching = false;
                        //invalidate();
                        break;

                }
               // mxMediaPlayer.Release();
                return true;
            }
        });;


        return rootView;
    }
