android 应用实现 google 自动完成 activity 2 个输入

Question

我的 app.One 中有 2 个编辑文本输入来自 place，另一个到 place.For 这 2 个输入我已经实现 google 自动完成 activity 但是问题当用户单击这些输入中的任何一个时 google 自动完成意图在用户位置选择完成后调用 onActivityResult()。在 onActivityResult() 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.
            }
        }
    }

我用了不同的方式。我为起点和终点分别创建了两个全局布尔值。然后当用户从某个地方单击或放置更改同一位置的布尔值时，然后在 onActivityResult 上检查哪个布尔值是 true 并将结果位置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，但有点老套。这样做的好方法是：

   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.
           }
        }
    }
