我的片段隐藏了导航抽屉？ [英] My Fragment hides the Navigation Drawer?
本文介绍了我的片段隐藏了导航抽屉？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个抽屉式导航在我的应用程序。如果我选择一个特定的项目和滑动抽屉式导航。该片段重叠导航抽屉。
我尝试添加 popBackStackImmediate（）; 但它是没有用的。这是它的样子

解决方案
以下变化所提出的 FloatingActionButton 和 FloatingActionMenu 类，允许一个特定的ViewGroup被设定为容器两者。测试是用一个类似但更简单的版本的code您发布而成，所以你可能需要作出调整你的设置参数。
该库code假定按钮和菜单都出现在上面的活动内容查看，一切都在其中。添加在 FloatingActionButton 类容器的ViewGroup成员允许我们指定一个孩子的ViewGroup是父母代替。请注意，以下更改只会工作，如果一个 FloatingActionButton 是用来与菜单。
在增加的 FloatingActionButton 类：
公共类FloatingActionButton扩展的FrameLayout {
...
私人的ViewGroup containerView;
...
公共FloatingActionButton（活动活动，
的LayoutParams的LayoutParams，
INT主题，
可绘制backgroundDrawable，
INT位置，
查看内容查看，
FrameLayout.LayoutParams contentParams
//注意增加下列内容
//构造函数这里参数
，ViewGroup中containerView）{
...
setClickable（真正的）;
//此行是新的。构造函数的其余部分是相同的。
this.containerView = containerView;
附加（的LayoutParams）;
}
...
公共查看getActivityContentView（）{
如果（containerView == NULL）{
返程（（活动）的getContext（））
。.getWindow（）getDecorView（）findViewById（android.R.id.content）。
} 其他 {
返回containerView;
}
}
公众的ViewGroup getContainerView（）{
返回containerView;
}
//下面设定器不是严格必需的，但也可以是使用
//如果你想切换按钮的和菜单的Z顺序放置
公共无效setContainerView（ViewGroup中containerView）{
this.containerView = containerView;
}
...
公共静态类生成器{
...
私人的ViewGroup containerView;
...
公共生成器setContainerView（ViewGroup中containerView）{
this.containerView = containerView;
回到这一点;
}
公共FloatingActionButton版本（）{
返回新FloatingActionButton（活动，
的LayoutParams，
主题，
backgroundDrawable，
位置，
内容查看，
contentParams，
//新说法
containerView）;
}
}
...
}
和更改到 FloatingActionMenu 类：
公共类FloatingActionMenu {
...
公共查看getActivityContentView（）{
如果（mainActionView的instanceof FloatingActionButton和放大器;＆安培;
（（FloatingActionButton）mainActionView）.getContainerView（）！= NULL）{
返回（（FloatingActionButton）mainActionView）.getContainerView（）;
} 其他 {
返程（（活动）mainActionView.getContext（））
。.getWindow（）getDecorView（）findViewById（android.R.id.content）。
}
}
...
}
然后，在片段的 onCreateView（）方法，我们需要添加一个调用新的 setContainerView（）的方法 FloatingActionButton.Builder 类。
公共类HomeFragment扩展片段{
...
@覆盖
公共查看onCreateView（LayoutInflater充气，容器的ViewGroup，
捆绑savedInstanceState）
{
...
FloatingActionButton leftCenterButton =新FloatingActionButton.Builder（getActivity（））
.setContentView（fabIconStar，空）
.setBackgroundDrawable（R.drawable.ic_launcher）
.setPosition（FloatingActionButton.POSITION_TOP_CENTER）
.setLayoutParams（starParams）
//新的方法调用此添加
.setContainerView（集装箱）
。建立（）;
...
}

解决方案
The following changes were made to the FloatingActionButton and FloatingActionMenu classes to allow a specific ViewGroup to be set as the container for both. Tests were made with a similar but simpler version of the code you've posted, so you may need to make adjustments to your setup parameters.
The library code assumes that the Button and Menu are to appear on top of an Activity's content View, and everything therein. The addition of a container ViewGroup member in the FloatingActionButton class allows us to specify a child ViewGroup to be the parent instead. Please note that the following changes will only work if a FloatingActionButton is used with the Menu.
The additions to the FloatingActionButton class:
public class FloatingActionButton extends FrameLayout {
...
private ViewGroup containerView;
...
public FloatingActionButton(Activity activity,
LayoutParams layoutParams,
int theme,
Drawable backgroundDrawable,
int position,
View contentView,
FrameLayout.LayoutParams contentParams
// Note the addition of the following
// constructor parameter here
, ViewGroup containerView) {
...
setClickable(true);
// This line is new. The rest of the constructor is the same.
this.containerView = containerView;
attach(layoutParams);
}
...
public View getActivityContentView() {
if(containerView == null) {
return ((Activity)getContext())
.getWindow().getDecorView().findViewById(android.R.id.content);
} else {
return containerView;
}
}
public ViewGroup getContainerView() {
return containerView;
}
// The following setter is not strictly necessary, but may be of use
// if you want to toggle the Button's and Menu's z-order placement
public void setContainerView(ViewGroup containerView) {
this.containerView = containerView;
}
...
public static class Builder {
...
private ViewGroup containerView;
...
public Builder setContainerView(ViewGroup containerView) {
this.containerView = containerView;
return this;
}
public FloatingActionButton build() {
return new FloatingActionButton(activity,
layoutParams,
theme,
backgroundDrawable,
position,
contentView,
contentParams,
// New argument
containerView);
}
}
...
}
And the changes to the FloatingActionMenu class:
public class FloatingActionMenu {
...
public View getActivityContentView() {
if(mainActionView instanceof FloatingActionButton &&
((FloatingActionButton) mainActionView).getContainerView() != null) {
return ((FloatingActionButton) mainActionView).getContainerView();
} else {
return ((Activity)mainActionView.getContext())
.getWindow().getDecorView().findViewById(android.R.id.content);
}
}
...
}
Then, in the Fragment's onCreateView() method, we need to add a call the new setContainerView() method of the FloatingActionButton.Builder class.
public class HomeFragment extends Fragment {
...
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
...
FloatingActionButton leftCenterButton = new FloatingActionButton.Builder(getActivity())
.setContentView(fabIconStar, null)
.setBackgroundDrawable(R.drawable.ic_launcher)
.setPosition(FloatingActionButton.POSITION_TOP_CENTER)
.setLayoutParams(starParams)
// The new method call is added here
.setContainerView(container)
.build();
...
}
...
}
