如何確定用戶是否觸摸了我的位圖？

Question

如何確定用戶是否單擊了ImageView的某些區域？

我在設置（x，y）坐標范圍以檢測何時單擊或不單擊特定位圖時有些困難。

例如，如果位圖的位置是（75,75），請說。 即，左上角在此點，那么，如果用戶在（X，Y）點觸摸屏幕，則簡單的條件為：

我在畫布上繪制的圖像位置為4（75,75），（645,75），（1215,75）和（75,490）。

它無法確定我單擊的內容，它總是給我消息“ mImaget”，而不是其他消息。

@Override
public boolean onTouch(View v, MotionEvent event) {
    int x = (int) event.getX();
    int y = (int) event.getY();
    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:

             if (x >= 75 && x < (75 + mImaget.getWidth())
                    && y >= 75 && y < (75 + mImaget.getHeight())) {
                Toast.makeText(getActivity(), "mImaget", Toast.LENGTH_SHORT).show();
                Log.e("TOUCHED", "X: " + x + " Y: " + y + mImaget.getWidth() + "-" + mImaget.getHeight());
            }

            if (x >= 645 && x < (645 + mImageth.getWidth())
                    && y >= 75 && y < (75 + mImageth.getHeight())) {
                Toast.makeText(getActivity(), "mImageth", Toast.LENGTH_SHORT).show();
                Log.e("TOUCHED", "X: " + x + " Y: " + y + mImageth.getWidth() + "-" + mImageth.getHeight());
            }

            if (x >= 1215 && x < (1215 + mImagef.getWidth())
                    && y >= 75 && y < (75 + mImagef.getHeight())) {
                Toast.makeText(getActivity(), "mImagef", Toast.LENGTH_SHORT).show();
                Log.e("TOUCHED", "X: " + x + " Y: " + y + mImagef.getWidth() + "-" + mImagef.getHeight());
            }

            if (x >= 75 && x < (75 + mImageo.getWidth())
                    && y >= 490 && y < (490 + mImageo.getHeight())) {
                Toast.makeText(getActivity(), "mImageo", Toast.LENGTH_SHORT).show();
                Log.e("TOUCHED", "X: " + x + " Y: " + y + mImageo.getWidth() + "-" + mImageo.getHeight());
            }

            return true;
    }
    return false;
}

謝謝 ：）

@Override
public boolean onTouch(View v, MotionEvent event) {
    int x = (int) event.getX();
    int y = (int) event.getY();
    switch (event.getAction()) {
        case MotionEvent.ACTION_DOWN:

            if (x >= 75 && x < (75 + mBack.getWidth())
                    && y >= 75 && y < (75 + mBack.getHeight())) {
                Toast.makeText(getActivity(), "Zone1: " + x +"-" + y, Toast.LENGTH_SHORT).show();
            }

            if (x >= 645 && x < (645 + mBack.getWidth())
                    && y >= 75 && y < (75 + mBack.getHeight())) {
                Toast.makeText(getActivity(), "Zone2: " + x +"-" + y, Toast.LENGTH_SHORT).show();
            }

            if (x >= 1215 && x < (1215 + mBack.getWidth())
                    && y >= 75 && y < (75 + mBack.getHeight())) {
                Toast.makeText(getActivity(), "Zone3: " + x +"-" + y, Toast.LENGTH_SHORT).show();
            }

            if (x >= 75 && x < (75 + mBack.getWidth())
                    && y >= 490 && y < (490 + mBack.getHeight())) {
                Toast.makeText(getActivity(), "Zone4: " + x +"-" + y, Toast.LENGTH_SHORT).show();
            }

            Log.d("TOUCHED", "X: " + x + " Y: " + y + mImaget.getWidth() + "-" + mImaget.getHeight());


            return true;
    }
    return false;
}

您能否嘗試一下代碼的這一部分而不是您的示例。
