明确重点内容时，​​导航抽屉显示 [英] clear focus on content when navigation drawer is showed

问题描述

什么是明确的焦点，有一个抽屉式导航栏中的一个机器人活动的最佳方式。

这是当用户有一个文本框选择，如果你打开​​导航抽屉它不是由抽屉消耗的背部事件，导航追溯到一步离开抽屉打开的问题。

现在我解决上的活动用这个，但我想知道是否有人使用其他的解决方案，在这里我就不需要使用ActionBarDrawerToggle事件。

  / **当抽屉处于完全开放的状态，先后落户调用。 * /
公共无效onDrawerOpened（查看drawerView）{
    视图窗口= findViewById（R.id.content_frame）;
    window.clearFocus（）;
}
 

解决方案

事实上，它似乎它打开时，抽屉没有焦点所以它的的onkeyup 将不调用。我在主机活动，并在 onBack pressed DrawerLayout＃hasFocus（）如果活动返回false选中此有获得焦点的视图 - 一个EditText或别的东西。

我甚至试图搞乱与 descendantFocusability 属性和没有工作。我设法用类似的方法解决这个问题，你做的事：抽屉布局要求重点：

  mDrawerLayout.setDrawerListener（新DrawerLayout.SimpleDrawerListener（）{
    @覆盖
    公共无效onDrawerOpened（查看drawerView）{
        mDrawerLayout.requestFocus（）;
    }
}）;
 

您正在清理从内容ViewGroup中的重点，但我不知道谁获得焦点的话，最有可能没有任何看法。

老实说，这似乎是我DrawerLayout一个错误，如果它是打开，它应该焦点上涨。

What would be the best way to clear the focus in an android activity having a navigation drawer.

The problem it's that when the user has a textbox selected, if you open the navigation drawer the back event it's not consumed by the drawer, and the navigation goes back one step leaving the drawer opened.

Right now I solved using this on the activity, but i would like to know if someone use another solution where i don't need to use the ActionBarDrawerToggle events.

/** Called when a drawer has settled in a completely open state. */
public void onDrawerOpened(View drawerView) {
    View window = findViewById(R.id.content_frame);
    window.clearFocus();
}

解决方案

Indeed it seems the drawer doesn't have focus when it's opened so it's onKeyUp won't be called. I checked this in the host activity and in onBackPressed DrawerLayout#hasFocus() returns false if the activity has a view that gained focus - an EditText or something else.

I even tried to mess up with its descendantFocusability property and that didn't work. I managed to fix this with a similar approach as you did: the drawer layout is requesting the focus:

mDrawerLayout.setDrawerListener(new DrawerLayout.SimpleDrawerListener() {
    @Override
    public void onDrawerOpened(View drawerView) {
        mDrawerLayout.requestFocus();
    }
});

You are clearing the focus from content ViewGroup, but I am not sure who gets the focus then, most probably no view.
Honestly speaking, this seems to me a bug in DrawerLayout as if it's opened, it should have the focus gained.
