安卓收获地址管理代码

以下是一个简单的安卓收货地址管理的代码示例：

1. Address类，用于存储地址信息

public class Address {
    private int id;
    private String name;
    private String phone;
    private String address;
    private String zipCode;
    private boolean isDefault;

    // 构造函数和Getter/Setter方法省略
}

2. AddressAdapter类，用于展示地址列表

public class AddressAdapter extends RecyclerView.Adapter<AddressAdapter.ViewHolder> {
    private List<Address> mAddresses;
    private OnItemClickListener mOnItemClickListener;

    public AddressAdapter(List<Address> addresses) {
        mAddresses = addresses;
    }

    public void setOnItemClickListener(OnItemClickListener listener) {
        mOnItemClickListener = listener;
    }

    public interface OnItemClickListener {
        void onItemClick(View view, int position);
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_address, parent, false);
        ViewHolder holder = new ViewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(final ViewHolder holder, int position) {
        Address address = mAddresses.get(position);
        holder.name.setText(address.getName());
        holder.phone.setText(address.getPhone());
        holder.address.setText(address.getAddress());
        holder.zipCode.setText(address.getZipCode());
        holder.defaultAddress.setChecked(address.isDefault());
        holder.defaultAddress.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int pos = holder.getAdapterPosition();
                Address address = mAddresses.get(pos);
                address.setDefault(holder.defaultAddress.isChecked());
                notifyDataSetChanged();
            }
        });
        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                int pos = holder.getAdapterPosition();
                if (mOnItemClickListener != null) {
                    mOnItemClickListener.onItemClick(holder.itemView, pos);
                }
            }
        });
    }

    @Override
    public int getItemCount() {
        return mAddresses.size();
    }

    static class ViewHolder extends RecyclerView.ViewHolder {
        TextView name;
        TextView phone;
        TextView address;
        TextView zipCode;
        CheckBox defaultAddress;

        public ViewHolder(View view) {
            super(view);
            name = view.findViewById(R.id.tv_name);
            phone = view.findViewById(R.id.tv_phone);
            address = view.findViewById(R.id.tv_address);
            zipCode = view.findViewById(R.id.tv_zip_code);
            defaultAddress = view.findViewById(R.id.cb_default_address);
        }
    }
}

3. AddressManager类，用于管理地址信息

public class AddressManager {
    private static AddressManager sInstance;
    private List<Address> mAddresses;
    private SharedPreferences mSharedPreferences;

    private AddressManager(Context context) {
        mSharedPreferences = context.getSharedPreferences("address", Context.MODE_PRIVATE);
        String addressesStr = mSharedPreferences.getString("addresses", "");
        if (!TextUtils.isEmpty(addressesStr)) {
            mAddresses = new Gson().fromJson(addressesStr, new TypeToken<List<Address>>(){}.getType());
        }
        if (mAddresses == null) {
            mAddresses = new ArrayList<>();
        }
    }

    public static AddressManager getInstance(Context context) {
        if (sInstance == null) {
            sInstance = new AddressManager(context);
        }
        return sInstance;
    }

    public List<Address> getAddresses() {
        return mAddresses;
    }

    public void addAddress(Address address) {
        mAddresses.add(address);
        saveAddresses();
    }

    public void deleteAddress(Address address) {
        mAddresses.remove(address);
        saveAddresses();
    }

    public void updateAddress(Address address) {
        for (Address addr : mAddresses) {
            if (addr.getId() == address.getId()) {
                addr.setName(address.getName());
                addr.setPhone(address.getPhone());
                addr.setAddress(address.getAddress());
                addr.setZipCode(address.getZipCode());
                addr.setDefault(address.isDefault());
                break;
            }
        }
        saveAddresses();
    }

    public void setDefaultAddress(Address address) {
        for (Address addr : mAddresses) {
            if (addr.getId() == address.getId()) {
                addr.setDefault(true);
            } else {
                addr.setDefault(false);
            }
        }
        saveAddresses();
    }

    private void saveAddresses() {
        String addressesStr = new Gson().toJson(mAddresses);
        mSharedPreferences.edit().putString("addresses", addressesStr).apply();
    }
}

4. AddressActivity类，用于展示地址列表和编辑地址信息

public class AddressActivity extends AppCompatActivity {
    private RecyclerView mRecyclerView;
    private AddressAdapter mAdapter;
    private List<Address> mAddresses;
    private int mSelectedPosition = -1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_address);

        mAddresses = AddressManager.getInstance(this).getAddresses();

        mRecyclerView = findViewById(R.id.recycler_view);
        LinearLayoutManager layoutManager = new LinearLayoutManager(this);
        mRecyclerView.setLayoutManager(layoutManager);
        mAdapter = new AddressAdapter(mAddresses);
        mAdapter.setOnItemClickListener(new AddressAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(View view, int position) {
                mSelectedPosition = position;
                Address address = mAddresses.get(position);
                Intent intent = new Intent(AddressActivity.this, EditAddressActivity.class);
                intent.putExtra("address", address);
                startActivityForResult(intent, 1);
            }
        });
        mRecyclerView.setAdapter(mAdapter);

        Button addButton = findViewById(R.id.btn_add);
        addButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(AddressActivity.this, EditAddressActivity.class);
                startActivityForResult(intent, 1);
            }
        });
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) {
            Address address = (Address) data.getSerializableExtra("address");
            if (requestCode == 1) {
                AddressManager.getInstance(this).addAddress(address);
            } else if (requestCode == 2) {
                AddressManager.getInstance(this).updateAddress(address);
            }
            mAdapter.notifyDataSetChanged();
        }
    }
}

5. EditAddressActivity类，用于编辑地址信息

public class EditAddressActivity extends AppCompatActivity {
    private EditText mNameEditText;
    private EditText mPhoneEditText;
    private EditText mAddressEditText;
    private EditText mZipCodeEditText;
    private CheckBox mDefaultCheckBox;

    private Address mAddress;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_edit_address);

        mNameEditText = findViewById(R.id.et_name);
        mPhoneEditText = findViewById(R.id.et_phone);
        mAddressEditText = findViewById(R.id.et_address);
        mZipCodeEditText = findViewById(R.id.et_zip_code);
        mDefaultCheckBox = findViewById(R.id.cb_default_address);

        mAddress = (Address) getIntent().getSerializableExtra("address");
        if (mAddress != null) {
            mNameEditText.setText(mAddress.getName());
            mPhoneEditText.setText(mAddress.getPhone());
            mAddressEditText.setText(mAddress.getAddress());
            mZipCodeEditText.setText(mAddress.getZipCode());
            mDefaultCheckBox.setChecked(mAddress.isDefault());
        }

        Button saveButton = findViewById(R.id.btn_save);
        saveButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (mAddress == null) {
                    mAddress = new Address();
                }
                mAddress.setName(mNameEditText.getText().toString());
                mAddress.setPhone(mPhoneEditText.getText().toString());
                mAddress.setAddress(mAddressEditText.getText().toString());
                mAddress.setZipCode(mZipCodeEditText.getText().toString());
                mAddress.setDefault(mDefaultCheckBox.isChecked());

                Intent intent = new Intent();
                intent.putExtra("address", mAddress);
                setResult(RESULT_OK, intent);
                finish();
            }
        });
    }
}

以上是一个简单的安卓收货地址管理的代码示例，仅供参考。根据实际需求，还需要进行适当的修改和完善。
