将 Umano/SlidingUpPanel 与虚假叠加问题一起使用
Using Umano/SlidingUpPanel With False Overlay Issue
我在我的应用程序中使用 Umano/SlidingUpPanel 库，其中地图是主要内容。一个面板在地图上向上滑动。我将 overlay 属性设为 false，因为我希望 主要内容在面板向上滑动时向上移动（就像 WhatsApp 聊天 Window） .
Issue i am facing is : My main content i.e. Map is shaking up or may
be re-sizing everytime panel slide up and down .

请帮我解决一下。谢谢
我不确定这个问题是否可以直接解决。但是我可以想象两种可能的解决方法：
- 尝试在 lite mode 中显示地图。您也可以尝试使用两张地图：第一张在默认模式下工作，第二张在精简模式下工作，然后在需要显示 sligin up 面板时在它们之间切换。
- 您可以将
PanelSlideListener 附加到 SligingUpPanel，将 overlay 属性设置为 true，然后在 PanelSlideListener.onPanelSlide 中将更改应用于 Camera使用 moveCamera/animateCamera 方法结合 setPadding 方法的地图对象（也可以移动地图控件）。这肯定会解决问题，因为地图视图不会调整大小，您将手动控制 Camera 对象。然而，这种方法需要做更多的工作。
UPDATE Here's 我建议的例子。希望我以正确的方式理解你的问题。您只需要创建一个空项目，在其中添加提供的 Activity 代码、布局和必要的依赖项 + 创建具有必要权限的适当 AndroidManifest。
您可以使用 android-transition 库将 Y 平移应用于地图视图：
Gradle:
compile 'com.github.kaichunlin.transition:core:0.9.4'
compile 'com.github.kaichunlin.transition:slidinguppanel:0.9.1'
代码：
SlidingUpPanelLayoutAdapter adapter=new SlidingUpPanelLayoutAdapter();
mLayout.setPanelSlideListener(adapter);
adapter.addTransition(ViewTransitionBuilder.transit(findViewById(R.id.map)).interpolator(new LinearInterpolator()).translationY(-250));
请注意，为了使其起作用，您必须将面板状态从隐藏更改为折叠，并将面板高度设置为 0:
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.COLLAPSED);
mLayout.setPanelHeight(0);
将面板状态设置为 EXPANDED 而不是 COLLAPSED：
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.EXPANDED);
并且在 sliding_fragment_layout.xml 中将 TableLayout 的 layout_height 设置为 500px，（应该改为使用 dp，但为了演示目的使用 px 就足够了）
效果演示：https://www.dropbox.com/s/gcozdrol8ed8zcc/test.mp4?dl=0
我认为最好的解决方案是使用视差效果。
您应该设置 umanoOverlay="true" 以确保地图保持其大小。然后，给滑动面板一个锚点（例如：umanoAnchorPoint="0.60"）和视差效果（例如：umanoParalaxOffset="250dp"）。单击标记时，为该标记设置动画相机以确保它位于地图中间。您还应该提供 umanoPanelHeight="0dp"，因为如果我理解为真，您希望通过单击标记来显示面板。
所以它会像
sothree:umanoAnchorPoint="0.60"
sothree:umanoDragView="@+id/dragView"
sothree:umanoParalaxOffset="250dp"
sothree:umanoPanelHeight="0dp"
sothree:umanoShadowHeight="0dp"
sothree:umanoFadeColor="@android:color/transparent"
sothree:umanoOverlay="true"
在您的标记点击侦听器中
@Override
public boolean onMarkerClick(Marker marker) {
points = new LatLng(marker.getPosition().latitude,marker.getPosition().longitude);
// if panel is collapsed
if (mLayout.getPanelState().equals(
SlidingUpPanelLayout.PanelState.COLLAPSED)) {
// then show the panel content
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.ANCHORED);
// animate your camera somehow
animateLatLngZoom(points, 0, -10, 10);
} else { // if panel is anchored or expanded
// collapse it
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.COLLAPSED);
}
return true;
}
我认为使用 sothree:umanoOverlay="false" 消除这种不需要的效果确实有问题，因为将该选项设置为 false 需要 Android 每次 [=] 高度时都对地图进行布局22=] 已更改。
因此，可能的解决方案是让您的滑动面板覆盖并跟踪它的上下移动，相应地调整您的地图平移。
这里有一个简单的例子：
@Override
public void onPanelSlide(View panel, float slidingOffset) {
adjustViews(slidingOffset, false);
}
@Override
public void onPanelCollapsed(View panel) {
}
@Override
public void onPanelExpanded(View panel) {
}
@Override
public void onPanelAnchored(View panel) {
adjustViews(mSlidingPanelLayout.getAnchorPoint(), true);
}
@Override
public void onPanelHidden(View view) {
}
private void adjustViews(final float slideOffset, boolean anchor) {
float height = mSlidingPanelLayout.getHeight();
float panelHeight = mSlidingPanelLayout.getPanelHeight();
mMapFragment.setMapTranslationY(-(int) ((height - panelHeight) * slideOffset) - mSlidingPanelLayout.getCurrentParalaxOffset());
}
我想您还需要做一些其他事情：在旋转期间实现 setMapTranslationY 和 saving/restoring 状态。

请帮我解决一下。谢谢
我不确定这个问题是否可以直接解决。但是我可以想象两种可能的解决方法：
- 尝试在 lite mode 中显示地图。您也可以尝试使用两张地图：第一张在默认模式下工作，第二张在精简模式下工作，然后在需要显示 sligin up 面板时在它们之间切换。
- 您可以将
PanelSlideListener附加到SligingUpPanel，将overlay属性设置为true，然后在PanelSlideListener.onPanelSlide中将更改应用于Camera使用moveCamera/animateCamera方法结合setPadding方法的地图对象（也可以移动地图控件）。这肯定会解决问题，因为地图视图不会调整大小，您将手动控制Camera对象。然而，这种方法需要做更多的工作。
UPDATE Here's 我建议的例子。希望我以正确的方式理解你的问题。您只需要创建一个空项目，在其中添加提供的 Activity 代码、布局和必要的依赖项 + 创建具有必要权限的适当 AndroidManifest。
您可以使用 android-transition 库将 Y 平移应用于地图视图：
Gradle:
compile 'com.github.kaichunlin.transition:core:0.9.4'
compile 'com.github.kaichunlin.transition:slidinguppanel:0.9.1'
代码：
SlidingUpPanelLayoutAdapter adapter=new SlidingUpPanelLayoutAdapter();
mLayout.setPanelSlideListener(adapter);
adapter.addTransition(ViewTransitionBuilder.transit(findViewById(R.id.map)).interpolator(new LinearInterpolator()).translationY(-250));
请注意，为了使其起作用，您必须将面板状态从隐藏更改为折叠，并将面板高度设置为 0:
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.COLLAPSED);
mLayout.setPanelHeight(0);
将面板状态设置为 EXPANDED 而不是 COLLAPSED：
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.EXPANDED);
并且在 sliding_fragment_layout.xml 中将 TableLayout 的 layout_height 设置为 500px，（应该改为使用 dp，但为了演示目的使用 px 就足够了）

我认为最好的解决方案是使用视差效果。
您应该设置 umanoOverlay="true" 以确保地图保持其大小。然后，给滑动面板一个锚点（例如：umanoAnchorPoint="0.60"）和视差效果（例如：umanoParalaxOffset="250dp"）。单击标记时，为该标记设置动画相机以确保它位于地图中间。您还应该提供 umanoPanelHeight="0dp"，因为如果我理解为真，您希望通过单击标记来显示面板。
所以它会像
sothree:umanoAnchorPoint="0.60"
sothree:umanoDragView="@+id/dragView"
sothree:umanoParalaxOffset="250dp"
sothree:umanoPanelHeight="0dp"
sothree:umanoShadowHeight="0dp"
sothree:umanoFadeColor="@android:color/transparent"
sothree:umanoOverlay="true"
在您的标记点击侦听器中
@Override
public boolean onMarkerClick(Marker marker) {
points = new LatLng(marker.getPosition().latitude,marker.getPosition().longitude);
// if panel is collapsed
if (mLayout.getPanelState().equals(
SlidingUpPanelLayout.PanelState.COLLAPSED)) {
// then show the panel content
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.ANCHORED);
// animate your camera somehow
animateLatLngZoom(points, 0, -10, 10);
} else { // if panel is anchored or expanded
// collapse it
mLayout.setPanelState(SlidingUpPanelLayout.PanelState.COLLAPSED);
}
return true;
}
我认为使用 sothree:umanoOverlay="false" 消除这种不需要的效果确实有问题，因为将该选项设置为 false 需要 Android 每次 [=] 高度时都对地图进行布局22=] 已更改。
因此，可能的解决方案是让您的滑动面板覆盖并跟踪它的上下移动，相应地调整您的地图平移。
这里有一个简单的例子：
@Override
public void onPanelSlide(View panel, float slidingOffset) {
adjustViews(slidingOffset, false);
}
@Override
public void onPanelCollapsed(View panel) {
}
@Override
public void onPanelExpanded(View panel) {
}
@Override
public void onPanelAnchored(View panel) {
adjustViews(mSlidingPanelLayout.getAnchorPoint(), true);
}
@Override
public void onPanelHidden(View view) {
}
private void adjustViews(final float slideOffset, boolean anchor) {
float height = mSlidingPanelLayout.getHeight();
float panelHeight = mSlidingPanelLayout.getPanelHeight();
mMapFragment.setMapTranslationY(-(int) ((height - panelHeight) * slideOffset) - mSlidingPanelLayout.getCurrentParalaxOffset());
}
我想您还需要做一些其他事情：在旋转期间实现 setMapTranslationY 和 saving/restoring 状态。
