Question

我在我的应用程序中有2个编辑文本输入。一个是从地方而另一个是放置。对于这两个输入我已经实现了谷歌自动完成活动但问题当用户点击这些输入中的任何一个谷歌自动完成意图用户后地点选择完成意图调用onActivityResult（）。在onActivityResult（）中如何知道点击了哪个输入。这是我的代码

    fromPlaceEdit.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    try {
                        AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
                                .setTypeFilter(AutocompleteFilter.TYPE_FILTER_REGIONS).setTypeFilter(AutocompleteFilter.TYPE_FILTER_GEOCODE)
                                .build();
                        Intent intent =
                                new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY).setFilter(typeFilter)
                                        .build(MainActivity.this);
                        startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);

                    } catch (GooglePlayServicesRepairableException e) {
                        // TODO: Handle the error.
                    } catch (GooglePlayServicesNotAvailableException e) {
                        // TODO: Handle the error.
                    }
                }
            });
toPlaceEdit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                try {
                    AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
                            .setTypeFilter(AutocompleteFilter.TYPE_FILTER_REGIONS).setTypeFilter(AutocompleteFilter.TYPE_FILTER_GEOCODE)
                            .build();
                    Intent intent =
                            new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY).setFilter(typeFilter)
                                    .build(MainActivity.this);
                    startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);

                } catch (GooglePlayServicesRepairableException e) {
                    // TODO: Handle the error.
                } catch (GooglePlayServicesNotAvailableException e) {
                    // TODO: Handle the error.
                }
            }
        });
@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == PLACE_AUTOCOMPLETE_REQUEST_CODE) {
            if (resultCode == RESULT_OK) {

                Place place = PlaceAutocomplete.getPlace(this, data);

                String fullName= (String) place.getAddress();
                #// here I want to know which input clicked and set fullname in input text#
                fromPlaceEdit.setText(fullName);
            } else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
                Status status = PlaceAutocomplete.getStatus(this, data);
                // TODO: Handle the error.
                Log.i("fdfdf", status.getStatusMessage());

            } else if (resultCode == RESULT_CANCELED) {
                // The user canceled the operation.
            }
        }
    }

我以不同的方式做到了。我已经为地点和地点创建了两个全局布尔值。然后，当用户从地点点击或放置相同位置的更改布尔值然后onActivityResult检查哪个布尔值为true并将结果地点名称设置为相同的输入框。代码如下：

public boolean fromplaceSlected =false ;
    public boolean toplaceSlected =false;
 fromPlaceEdit.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    try {
                        AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
                                .setTypeFilter(AutocompleteFilter.TYPE_FILTER_REGIONS).setTypeFilter(AutocompleteFilter.TYPE_FILTER_GEOCODE)
                                .build();
                        Intent intent =
                                new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY).setFilter(typeFilter)
                                        .build(MainActivity.this);
                        startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);

                    } catch (GooglePlayServicesRepairableException e) {
                        // TODO: Handle the error.
                    } catch (GooglePlayServicesNotAvailableException e) {
                        // TODO: Handle the error.
                    }
                }
            });
toPlaceEdit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                try {
                    AutocompleteFilter typeFilter = new AutocompleteFilter.Builder()
                            .setTypeFilter(AutocompleteFilter.TYPE_FILTER_REGIONS).setTypeFilter(AutocompleteFilter.TYPE_FILTER_GEOCODE)
                            .build();
                    Intent intent =
                            new PlaceAutocomplete.IntentBuilder(PlaceAutocomplete.MODE_OVERLAY).setFilter(typeFilter)
                                    .build(MainActivity.this);
                    startActivityForResult(intent, PLACE_AUTOCOMPLETE_REQUEST_CODE);

                } catch (GooglePlayServicesRepairableException e) {
                    // TODO: Handle the error.
                } catch (GooglePlayServicesNotAvailableException e) {
                    // TODO: Handle the error.
                }
            }
        });
@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        Log.e("request", String.valueOf(requestCode));
        // Check that the result was from the autocomplete widget.
        if (requestCode == REQUEST_CODE_AUTOCOMPLETE) {
            if (resultCode == RESULT_OK) {
                // Get the user's selected place from the Intent.
                Place place = PlaceAutocomplete.getPlace(getContext(), data);

                String fullName = (String) place.getAddress();

                if(fromplaceSlected){
                    Log.e("from place",fullName);
                    fromPlaceEdit.setText(fullName);
                    fromplaceSlected=false;
                    toplaceSlected=false;
                }
                else if(toplaceSlected){
                    Log.e("toplace" ,fullName);
                    toPlaceEdit.setText(fullName);
                    fromplaceSlected=false;
                    toplaceSlected=false;
                }

            } else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
                Status status = PlaceAutocomplete.getStatus(getContext(), data);
                Log.e("sdsdsdd", "Error: Status = " + status.toString());
                fromplaceSlected=false;
                toplaceSlected=false;
            } else if (resultCode == RESULT_CANCELED) {
                // Indicates that the activity closed before a selection was made. For example if
                // the user pressed the back button.
                fromplaceSlected=false;
                toplaceSlected=false;
            }
        }

    }

您的代码可能有效，但有点骇人听闻。这是做到这一点的好方法：

   public static final int PLACE_AUTOCOMPLETE_FROM_PLACE_REQUEST_CODE=1;
   public static final int PLACE_AUTOCOMPLETE_TO_PLACE_REQUEST_CODE=2;

fromPlaceEdit.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    try {
                      //Do your stuff from place
                        startActivityForResult(intent, PLACE_AUTOCOMPLETE_FROM_PLACE_REQUEST_CODE);

                    } catch (GooglePlayServicesRepairableException e) {
                        // TODO: Handle the error.
                    } catch (GooglePlayServicesNotAvailableException e) {
                        // TODO: Handle the error.
                    }
                }
            });
toPlaceEdit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                try {
                   //Do your stuff to place
                    startActivityForResult(intent, PLACE_AUTOCOMPLETE_TO_PLACE_REQUEST_CODE);

                } catch (GooglePlayServicesRepairableException e) {
                    // TODO: Handle the error.
                } catch (GooglePlayServicesNotAvailableException e) {
                    // TODO: Handle the error.
                }
            }
        });
@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
       if (requestCode == PLACE_AUTOCOMPLETE_FROM_PLACE_REQUEST_CODE) {
           if (resultCode == RESULT_OK) {
              //Do your ok >from place< stuff here
           } else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
              //Handle your error >from place<
           } else if (resultCode == RESULT_CANCELED) {
               // The user canceled the operation.
           }
       } else if (requestCode == PLACE_AUTOCOMPLETE_TO_PLACE_REQUEST_CODE) {
           if (resultCode == RESULT_OK) {
              //Do your ok >to place< stuff here
           } else if (resultCode == PlaceAutocomplete.RESULT_ERROR) {
              //Handle your error >to place<
           } else if (resultCode == RESULT_CANCELED) {
               // The user canceled the operation.
           }
        }
    }
