我正在爲android製作一個鋼琴應用程序。作爲示例（測試），我的活動中有4個按鈕。父母是Relative Layout，我也有一些文字說明，指出手指觸摸的屏幕座標。還有一個TextView的（「輸入鍵」）檢測，如果你的手指在按鈕或不
這是什麼樣子：
將按鈕傳遞給家長的屏幕座標
我實現了這個使用下面給出的代碼。
的Java
public class MainActivity extends Activity {
Button b1, b2, b3, b4;
int b1x1, b1x2, b1y1, b1y2;
private TextView xcordview;
private TextView ycordview;
private TextView buttonIndicator;
private RelativeLayout touchview;
private static int defaultStates[];
private Button mLastButton;
private final static int[] STATE_PRESSED = {
android.R.attr.state_pressed,
android.R.attr.state_focused
| android.R.attr.state_enabled };
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
xcordview = (TextView) findViewById(R.id.textView4);
ycordview = (TextView) findViewById(R.id.textView3);
buttonIndicator = (TextView) findViewById(R.id.button_indicator);
touchview = (RelativeLayout) findViewById(R.id.relativelayout);
b1 = (Button) findViewById(R.id.button1);
b2 = (Button) findViewById(R.id.button2);
b3 = (Button) findViewById(R.id.button3);
b4 = (Button) findViewById(R.id.button4);
defaultStates = b1.getBackground().getState();
}
@Override
protected void onResume() {
// TODO Auto-generated method stub
super.onResume();
touchview.setOnTouchListener(new View.OnTouchListener() {
private boolean isInside = false;
@Override
public boolean onTouch(View v, MotionEvent event) {
int x = (int) event.getX();
int y = (int) event.getY();
xcordview.setText(String.valueOf(x));
ycordview.setText(String.valueOf(y));
for (int i = 0; i < touchview.getChildCount(); i++) {
View current = touchview.getChildAt(i);
if (current instanceof Button) {
Button b = (Button) current;
if (!isPointWithin(x, y, b.getLeft(), b.getRight(), b.getTop(),
b.getBottom())) {
b.getBackground().setState(defaultStates);
}
if (isPointWithin(x, y, b.getLeft(), b.getRight(), b.getTop(),
b.getBottom())) {
b.getBackground().setState(STATE_PRESSED);
if (b != mLastButton) {
mLastButton = b;
buttonIndicator.setText(mLastButton.getText());
}
}
}
}
return true;
}
});
}
@Override
public void onWindowFocusChanged(boolean hasFocus) {
// TODO Auto-generated method stub
super.onWindowFocusChanged(hasFocus);
}
static boolean isPointWithin(int x, int y, int x1, int x2, int y1, int y2) {
return (x <= x2 && x >= x1 && y <= y2 && y >= y1);
}
}

所以上面給出此代碼工作正常，因爲它承認，當我在任何按鈕輕掃我的手指從空格（相對佈局） 。但是當我從一個按鈕滑動到另一個按鈕時，它不起作用。它沒有得到任何座標，也沒有感覺到我的手指結束了哪個按鈕。下面的圖片最好地解釋了當我從一個按鈕滑動到另一個按鈕時會發生什麼。
那麼，如何獲取座標，同時從一個鍵滑動到另一個？
當你刷卡，被甩，並獲得頂部與您的佈局，使相對佈局0,0是佈局的左上角，但是當您從按鈕0滑動時，0是您窗口小部件的左上角，請在以下鏈接中查看我的回答，m aybe可以幫助你，http://stackoverflow.com/questions/20988635/android-lock-screen-app-button-hover-and-sequence/20988839#20988839 –
謝謝！但它不會支持
只是複製和過去的代碼到新項目，如果你刪除動畫，那麼它的工作適用於所有版本， –
