对话框中的MapView
我使用dialogFragment.show(this);
此片段的内容视图为ScrollView，底部为MapView。由于存在onInterceptTouchEvent，ScrollView会照顾MapView。当用作普通片段时，它工作正常。但作为对话框，滚动时会发生这种情况。
MapView退出Dialog。
修改
这没有用：
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="160dp"
android:layout_below="@id/view_text" >
<com.google.android.gms.maps.MapView
android:id="@+id/view_map"
android:layout_width="match_parent"
android:layout_height="160dp"
map:uiRotateGestures="true"
map:uiScrollGestures="true"
map:uiTiltGestures="false"
map:uiZoomControls="false"
map:uiZoomGestures="true" />
<View
android:layout_width="match_parent"
android:layout_height="160dp" />
</RelativeLayout>

这些是我必须在对话框或片段（或视图寻呼机）中放置地图时遵循的步骤。
先决条件：已经有游戏服务库，添加了INTERNET，WRITE_EXTERNAL_STORAGE等权限以及地图密钥和播放服务的元数据。
第1步：创建使用地图的透明地图类 此类将在透明框架布局中添加地图，以删除默认黑色图层（在某些设备中显示）。
public class TransparentMapFragment extends MapFragment {
public TransparentMapFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup view,
Bundle savedInstance) {
View layout = super.onCreateView(inflater, view, savedInstance);
FrameLayout frameLayout = new FrameLayout(getActivity());
frameLayout.setBackgroundColor(getResources().getColor(
android.R.color.transparent));
((ViewGroup) layout).addView(frameLayout, new ViewGroup.LayoutParams(
LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT));
return layout;
}
public static TransparentMapFragment newInstance(String abc) {
TransparentMapFragment tsf = new TransparentMapFragment();
return tsf;
}
}
步骤2：对话框片段更改对话框片段的样式
<style name="Theme.Default.Dialog" parent="@android:style/Theme.Dialog"></style>
<style name="Theme.CustomDialog" parent="Theme.Default.Dialog">
<item name="android:windowIsTranslucent">true</item>
<item name="android:windowBackground">@android:color/transparent</item>
<item name="android:windowContentOverlay">@null</item>
<item name="android:colorBackgroundCacheHint">@null</item>
</style>
第3步：对话框布局根据需要创建全屏对话框并添加填充。我在这里使用的是60dip
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="60dip" >
<ScrollView [Use your lockable scroll view]
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#fff" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="8dip"
android:text="Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

android:textColor="#000"
android:textSize="12sp" />
<fragment
android:id="@+id/map"
android:name="com.app.widgets.TransparentMapFragment [Path of Transparent Map]"
android:layout_width="match_parent"
android:layout_height="100dip" />
</LinearLayout>
</ScrollView>
</FrameLayout>
步骤4：设置对话框片段类正常实施地图
public class MapDialogFragment extends DialogFragment {
private View view;
private GoogleMap mMap;
private double lat;
private double lon;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Dialog dialog = new Dialog(getActivity(),
R.style.Theme_CustomDialog);
LayoutInflater inflater = getActivity().getLayoutInflater();
view = inflater.inflate(R.layout.dialog_map, null);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(view);
// Creating Full Screen
dialog.getWindow().setLayout(LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT);
return dialog;
}
@Override
public void onActivityCreated(Bundle bundle) {
super.onActivityCreated(bundle);
initializeViews();
}
private void initializeViews() {
setUpMapIfNeeded();
}
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the
// map.
if (mMap == null) {
// Try to obtain the map from the SupportMapFragment.
mMap = ((TransparentMapFragment) getActivity().getFragmentManager()
.findFragmentById(R.id.map)).getMap();
mMap.getUiSettings().setZoomControlsEnabled(false);
if (isGoogleMapsInstalled()) {
if (mMap != null) {
setUpMap();
}
} else {
Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage("installGoogleMaps");
builder.setCancelable(false);
builder.setPositiveButton("install", getGoogleMapsListener());
AlertDialog dialog = builder.create();
dialog.show();
}
}
}
private void setUpMap() {
lat = 28.6100;
lon = 77.2300;
final LatLng position = new LatLng(lon, lat);
mMap.clear();
mMap.getUiSettings().setAllGesturesEnabled(false);
mMap.addMarker(new MarkerOptions().position(position).snippet(""));
}
public boolean isGoogleMapsInstalled() {
try {
getActivity().getPackageManager().getApplicationInfo(
"com.google.android.apps.maps", 0);
return true;
} catch (PackageManager.NameNotFoundException e) {
return false;
}
}
public android.content.DialogInterface.OnClickListener getGoogleMapsListener() {
return new android.content.DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(
Intent.ACTION_VIEW,
Uri.parse("market://details?id=com.google.android.apps.maps"));
startActivity(intent);
// Finish the fragment so they can't circumvent the check
if (getActivity() != null) {
Fragment fragment = (getActivity().getFragmentManager()
.findFragmentByTag(MapFragment.class.getName()));
FragmentTransaction ft = getActivity().getFragmentManager()
.beginTransaction();
ft.remove(fragment);
ft.commitAllowingStateLoss();
}
}
};
}
@Override
public void onDestroyView() {
super.onDestroyView();
if (getActivity() != null) {
try {
Fragment fragment = (getActivity().getFragmentManager()
.findFragmentById(R.id.map));
FragmentTransaction ft = getActivity().getFragmentManager()
.beginTransaction();
ft.remove(fragment);
ft.commitAllowingStateLoss();
} catch (Exception e) {
}
}
}
}
结果：
希望它会有所帮助。 ：）

这是众所周知的问题。尝试使用此结构（original post here）包装MapView。
<FrameLayout
android:layout_width="match_parent"
android:layout_height="160dp"
>
<com.google.android.gms.maps.MapView
android:id="@+id/view_map"
android:layout_width="match_parent"
android:layout_height="match_parent"
map:uiRotateGestures="true"
map:uiScrollGestures="true"
map:uiTiltGestures="false"
map:uiZoomControls="false"
map:uiZoomGestures="true"
/>
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</FrameLayout>
答案 2 :(得分：0)
对我来说，要使其正常工作，我只需要在对话框中添加样式：
<style name="Theme.CustomDialog" parent="@android:style/Theme.Dialog">
<item name="android:windowBackground">@android:color/transparent</item>
</style>
Dialog片段中的onCreateDialog方法：
override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
val dialog = Dialog(activity,
R.style.Theme_CustomDialog)
val inflater = activity?.layoutInflater
val view = inflater?.inflate(R.layout.poi_details_dialog_fragment, null)
dialog.setContentView(view)
//Putting the size of the window with margins
val display = activity?.windowManager?.defaultDisplay
val size = Point()
display?.getSize(size)
val width = size.x
val height = size.y
dialog.window.setLayout(width - resources
.getDimensionPixelSize(R.dimen.margin_start_poi_dialog),
height - resources
.getDimensionPixelSize(R.dimen.margin_top_poi_dialog))
return dialog
}
