android - 来自 Android 抽屉的 ViewDragHelper 的过多日志

Question

当我的用户执行某些涉及拖动对象的操作时，我将禁用 Android 抽屉导航。这是为了防止他们不小心打开抽屉。问题是我被日志消息淹没了。这使得解决其他问题变得困难。

这就是我锁抽屉的方式。

drawer.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);

这是我收到的日志消息。

E/ViewDragHelper: Ignoring pointerId=0 because ACTION_DOWN was not received for this pointer before ACTION_MOVE. It likely happened because  ViewDragHelper did not receive all the events in the event stream.

我遇到了同样的问题，我使用 requestDisallowInterceptTouchEvent 函数解决了这个问题，如下所示:

public void blockMainMenu(){
    ((DrawerLayout) findViewById(R.id.drawer_layout)).requestDisallowInterceptTouchEvent(true);
    ((DrawerLayout) findViewById(R.id.drawer_layout)).setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_OPEN);
}
public void unblockMainMenu(){
    ((DrawerLayout) findViewById(R.id.drawer_layout)).requestDisallowInterceptTouchEvent(false);
    ((DrawerLayout) findViewById(R.id.drawer_layout)).setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
}

因此，当我阻止我的 DrawerLayout 时，我不允许触摸事件，并且 Log 不会显示很多错误消息，说明它们丢失了很多事件。

希望对您有所帮助!
