那麼這些是我用於跟蹤時，我必須把地圖對話框或片段（或視圖尋呼機）的步驟。
先決條件：已經有播放服務庫，增加了像INTERNET，WRITE_EXTERNAL_STORAGE和地圖關鍵和播放服務元數據的權限。
步驟1：用於使用地圖 這個類將增加在一個透明幀佈局地圖用於去除默認黑層創建一個透明地圖類（出現在某些設備）。
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;
}
}
第2步：對於對話片段
<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>
步驟3的對話片段轉變作風：佈局對話框創建一個全屏幕對話框，並根據您的需要添加了補。這裏我使用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>
第4步：設置對話框片段類法線貼圖
實施
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) {
}
}
}
}
結果：
希望它能幫助謝謝。 :)
意味着你需要什麼？該地圖需要在對話框中？ – 2014-11-03 06:53:21
@AndoMasahashi當滾動時，mapview不應該出現在對話框中。當滾動出對話框時，它必須像文本的最後一行一樣隱藏。就像典型的滾動視圖一樣。 – 2014-11-03 07:00:24
你可以提供示例代碼來處理它嗎？ – 2014-11-03 07:01:37
