我的代码就像这样

public class VehicleDetailsActivity extends Activity implements OnClickListener, Serializable {
    Button nextbutton;
    EditText vehiclemodel;
    EditText vehiclemake;
    EditText vehiclenumber;
    EditText seat;
    EditText kilometers;
    RadioGroup selectvehicle;
    RadioButton vehicletype;
    String vcategory;
    ArrayList<NameValuePair> vehicleinfo = new ArrayList<NameValuePair>();
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.vehicledetails);
        setTitle("VEHICLE DETAILS");
        nextbutton = (Button) findViewById(R.id.next);
        nextbutton.setOnClickListener(this);
    }
@Override
public void onClick(View v) {
    switch (v.getId()) {
    case R.id.next:

        Bundle vehicledetails = new Bundle();
        vehiclemodel = (EditText) findViewById(R.id.vehiclemodel);
        vehiclemake = (EditText) findViewById(R.id.vehiclemake);
        vehiclenumber = (EditText) findViewById(R.id.vehiclenumber);
        seat = (EditText) findViewById(R.id.seat);
        kilometers = (EditText) findViewById(R.id.kilometer);
        selectvehicle = (RadioGroup) findViewById(R.id.selectvehicle);
        int selected_vehile = selectvehicle.getCheckedRadioButtonId();
        vehicletype = (RadioButton) findViewById(selected_vehile);

        if(vehicletype.getText() == "premium") {
            vcategory = "1";
        }
        else if(vehicletype.getText() == "Economy") {
            vcategory = "2";
        }
        else {
            vcategory = "3";
        }
        vehicleinfo.add(new BasicNameValuePair("vehicle_model", vehiclemodel.getText().toString()));    
        vehicleinfo.add(new BasicNameValuePair("vehicle_make", vehiclemake.getText().toString().trim()));
        vehicleinfo.add(new BasicNameValuePair("vehicle_number", vehiclenumber.getText().toString()));
        vehicleinfo.add(new BasicNameValuePair("seat", seat.getText().toString().trim()));
        vehicleinfo.add(new BasicNameValuePair("kilometer", kilometers.getText().toString().trim()));
        vehicleinfo.add(new BasicNameValuePair("vehicle_type", vcategory));
        Intent it = new Intent(this, SetLocationActivity.class);

          it.putExtra("vehicleinfo", vehicleinfo);
        startActivity(it);
        break;
    }
}
 }

我成功地能够通过bundle传递数据，但我想要数组列表，因为在下一个活动ican中添加新值并且可以将该arraylist传递给我的webservice。

Answer 1

扩展BasicNameValuePair类及其中的任何包含对象类（如果有）也＆＃34;实现Serializable＆＃34;：

public class Example extends BasicNameValuePair implements Serializable {

}

将具有名称值对的arraylist从一个活动传递到另一个活动？
