我在我的应用程序中使用Umano / SlidingUpPanel lib，其中Map是主要内容。面板在地图上向上滑动。我将叠加属性设置为，因为我希望当面板上滑时主要内容向上移动（如WhatsApp聊天窗口）。
我面临的问题是：我的主要内容即地图正在震动或可能 每次面板上下滑动时都要重新调整大小。

当面板上下滑动时，地图会发抖。

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：
PanelSlideListener附加到SligingUpPanel，将overlay属性设置为true，然后PanelSlideListener.onPanelSlide将更改应用于Camera使用moveCamera / animateCamera方法结合setPadding方法（也可以移动地图控件）的地图。这肯定会解决问题，因为地图视图无法调整大小，而是您手动控制Camera对象。然而，这种方法需要做更多的工作。 更新 Here's我建议的一个例子。希望我能以正确的方式理解你的问题。您只需要创建一个空项目，添加提供Activity代码，它的布局和必要的依赖关系+创建具有必要权限的相应AndroidManifest。

您可以使用android-transition库将Y翻译应用于地图视图：
摇篮：
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，为了使其正常工作，您必须将面板状态从HIDDEN更改为COLLAPSED，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);
并且还在sliding_fragment_layout.xml中将TableLayout的layout_height设置为500px（应该更改为使用dp，但使用px足以用于演示目的）

答案 2 :(得分：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，给出一个锚点（例如：umanoAnchorPoint =“0.60”）和视差效果（例如：umanoParalaxOffset =“250dp”）向上滑动面板。单击标记时，将相机设置为此标记的动画，以确保它位于地图的中间。您还应该给umanoPanelHeight =“0dp”，因为如果我得到它，您只想点击标记来显示面板。
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"
@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"摆脱这种不受欢迎的影响是非常有问题的，因为将该选项设置为false需要Android在每次更改表格高度时布置地图。
因此，可能的解决方案是让您的滑动面板叠加并上下跟踪它的移动，相应地调整地图的翻译。
这是一个简短的例子：
@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());
}
你需要做一些我认为的其他事情：在旋转过程中实现setMapTranslationY和保存/恢复状态。
