android - 如何从 FragmentActivity 显示 CustomDialog
问题描述
从 FragmentActivity 显示自定义对话框时，我收到了我在下面写的错误。
我得到的错误：
android.view.WindowManager$BadTokenException: 无法添加窗口 -- 令牌 null 不适用于应用程序
这是我的 DriverMapActivity，我从中显示自定义对话框：
注意：我删除了一些与我的问题无关的代码
DriverMap FragmentActivity
public class DriverMapActivity extends FragmentActivity{
private GoogleMap mMap;
GoogleApiClient googleApiClient;
SupportMapFragment mapFragment;
LocationRequest mLocationRequest;
private Location lastLocation;
private FirebaseAuth mAuth;
private Switch workingswitch;
private String customerId, userId;
private Toolbar toolbar;
private NavigationView navigationView;
private DrawerLayout drawerLayout;
private DatabaseReference driverInfoDB;
private String name, surname, profileimageURL;
private String distancetopick,distancetodes;
private int distancefinal;
private Button yesBtn, noBtn;
private UserInfoShower cdd;
private int cameraupdatedandzoomed;
private Map<String,String> infoMap;
private LatLng pickupLoc;
private LatLng destiantionLoc;
private Marker pickupMarker, destinationMarker;
private float rideDistance;
private Button btnzoom;
private String customerprofileUrl;
private Button logoutbtn, settingsbtn, historybtn, opendrawer;
private boolean pickupgeted;
private String rideStatus = "";
private LatLng target;
@SuppressLint("NewApi")
@RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_driver_map);
customerId = "";
cameraupdatedandzoomed=0;
mAuth = FirebaseAuth.getInstance();
toolbar = findViewById(R.id.toolbar);
polylines = new ArrayList<>();
userId = FirebaseAuth.getInstance().getCurrentUser().getUid();
btnzoom=findViewById(R.id.btnzoom);
pickupgeted = false;
startService(new Intent(DriverMapActivity.this,onAppKilled.class));
navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(this);
// This method will trigger on item Click of navigation menu
// Initializing Drawer Layout and ActionBarToggle
drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
setDriverStuffToNavView();
btnzoom.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(lastLocation!=null)
{
}
else
{
Toast.makeText(DriverMapActivity.this, "Turn on Working
}
}
});
private void listenForCustomerRequest() {
String userId = FirebaseAuth.getInstance().getCurrentUser().getUid();
DatabaseReferencelistenerRef=FirebaseDatabase.getInstance().getReference()
.child("Users").child("Drivers").child(userId).child("CustomerRequest");
listenerRef.addChildEventListener(new ChildEventListener() {
public void onChildAdded(@NonNull DataSnapshot dataSnapshot, String s) {
if (dataSnapshot.exists()) {
customerId = dataSnapshot.getKey();
showUserInfo();
}
}
});
}
这是我显示CustomDialog的方法：
UserInfoShower 方法
注意：我删除了一些与我的问题无关的代码
private void showUserInfo() {
DatabaseReferenceuserinfoRef=FirebaseDatabase.getInstance().getReference()
.child("Users").child("Customers").child(customerId);
Log.i("TEST", "CustomerId Comes Driver " + customerId);
infoMap=new HashMap<>();
cdd = new UserInfoShower(DriverMapActivity.this,infoMap);
DatabaseReferenceuserInfoDB=FirebaseDatabase.getInstance().getReference()
.child("Users").child("Customers").child(customerId);
userInfoDB.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
if (dataSnapshot.exists() && dataSnapshot.getChildrenCount() > 0) {
Map<String, Object> map = (Map<String, Object>)
dataSnapshot.getValue();
infoMap.put("DriverOrCus", "1");
infoMap.put("Name", map.get("name").toString());
infoMap.put("Surname", map.get("surname").toString());
if(map.get("profileimageURL") !=null)
{
infoMap.put("profileimageURL",
map.get("profileimageURL").toString());
customerprofileUrl=map.get("profileimageURL").toString();
}
infoMap.put("customerId", customerId);
cdd = new UserInfoShower(DriverMapActivity.this,infoMap);
cdd.show();
cdd.setCanceledOnTouchOutside(false);
yesBtn = cdd.findViewById(R.id.yesBtn);
noBtn = cdd.findViewById(R.id.noBtn);
yesBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
String userId=FirebaseAuth.getInstance().
getCurrentUser().getUid();
DatabaseReference decisionRef=FirebaseDatabase.
getInstance().getReference().
child("Users").child("Drivers").child(userId).child("CustomerRequest")
.child(customerId)
.child("driverDecision");
decisionRef.setValue("YES").addOnCompleteListener(newOnCompleteListener
<Void>() {
@Override
public void onComplete(@NonNull
Task<Void>task) {
cdd.cancel();
cdd.dismiss();
cdd=null;
getCustomerRideInfo();
}
});
}
});
}
当我调用 cdd.show(); 时发生错误
这是 UserInfoShower 对话框：
public class UserInfoShower extends Dialog {
public Context c;
private Button noBtn, yesBtn;
private String name, surname, profileimageURL;
private TextView customerName, customerSurname;
private ImageView customerprofile;
private int position;
private String driverId;
private LatLng CustomerPickupLoc, CustomerDestinationLoc;
private String customerId, desName;
private SharedPreferences sharedpref;
Map<String,String> infoMap;
public UserInfoShower(Context a,Map<String,String> infoMap) {
super(a);
this.c = a;
this.infoMap=infoMap;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_customer_info_shower);
noBtn = findViewById(R.id.noBtn);
yesBtn = findViewById(R.id.yesBtn);
customerName = findViewById(R.id.customerName);
customerSurname = findViewById(R.id.customerSurname);
customerprofile = findViewById(R.id.customerprofile);
position = Integer.valueOf(infoMap.get("DriverOrCus"));
if (position == 1) {
showCusInfo();
} else {
showDriverInfo();
}
yesBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (position == 1) // If user is Driver
{
dismiss();
} else //if user is Cusomer And Liked Driver
{
dismiss();
}
}
});
noBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (position == 1) //if User is Driver
{
dismiss();
} else// if User is Customer And not liked Driver
{
dismiss();
}
}
});
}
private void showCusInfo() {
name = infoMap.get("Name");
surname = infoMap.get("Surname");
customerId = infoMap.get("customerId");
customerName.setText("Name " + name);
customerSurname.setText("Surname " + surname);
}
@Override
public void onAttachedToWindow() {
super.onAttachedToWindow();
}
public static boolean isValidContextForGlide(final Context context) {
if (context == null) {
return false;
}
if (context instanceof Activity) {
final Activity activity = (Activity) context;
if (activity.isDestroyed() || activity.isFinishing()) {
return false;
}
}
return true;
}
}
这是我的对话框 xml 文件：
