android防止button多次被點擊工具類

public class Tools {
private static long lastClickTime;
public static boolean isFastDoubleClick() {
long time = System.currentTimeMillis();

if ( time - lastClickTime < 500) {

return true;

}

lastClickTime = time;

return false;

}
}

使用的時候
public void onClick(View v) {
if (Tools .isFastDoubleClick()) {
return;
}
}
