我有6個可打開應用程序的按鈕(綠色)。在這個按鈕的頂部有另一個按鈕,我用它來滑動偵聽器。Android單擊另一個按鈕後面的按鈕
如果未檢測到刷卡(單擊)我想單擊綠色按鈕,否則執行由紅色按鈕觸發的刷卡操作。
這裏從here
public class OnSwipeTouchListener implements OnTouchListener {
private final GestureDetector gestureDetector;
public OnSwipeTouchListener (Context ctx){
gestureDetector = new GestureDetector(ctx, new GestureListener());
}
@Override
public boolean onTouch(View v, MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
private final class GestureListener extends SimpleOnGestureListener {
private static final int SWIPE_THRESHOLD = 100;
private static final int SWIPE_VELOCITY_THRESHOLD = 100;
@Override
public boolean onDown(MotionEvent e) {
return true;
}
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
boolean result = false;
try {
float diffY = e2.getY() - e1.getY();
float diffX = e2.getX() - e1.getX();
if (Math.abs(diffX) > Math.abs(diffY)) {
if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
if (diffX > 0) {
onSwipeRight();
} else {
onSwipeLeft();
}
result = true;
}
}
else if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
if (diffY > 0) {
onSwipeBottom();
} else {
onSwipeTop();
}
result = true;
}
} catch (Exception exception) {
exception.printStackTrace();
}
return result;
}
}
public void onSwipeRight() {}
public void onSwipeLeft() {}
public void onSwipeTop() {}
public void onSwipeBottom() {}
public void onTap() {}
}
了我的TouchListener這是我初始化監聽器。
Button ok = (Button) findViewById(R.id.btn_hex_over);
final Context c = context;
ok.setOnTouchListener(new OnSwipeTouchListener(getBaseContext()) {
public void onSwipeTop() {}
public void onSwipeBottom() {}
public void onTap() {}
});
滑動工作,但不能單擊按鈕。
你的onClickListener在哪裏? – Ankita
你不需要'GestureListener'的紅色按鈕。簡單的佈局也能完成這項工作。 –
@MuratK。但我需要整個表面上的聽衆,而不僅僅是按鈕 – CBeTJlu4ok
