从多个edittext框检索，保存和发送文本时遇到问题

标签： android-intent android-edittext

我一直在尝试从不同的教程，问题响应等不同的方式，仍然无法让我的应用程序不仅从多个edittext检索文本，而是保存到一个对象，然后移动到新的活动传递要显示为确认的文本。我将发布我写过的两次尝试。

第一次尝试     包com.zombiecatandroidapp; 

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.widget.EditText;
import android.widget.RatingBar;

public class ChefCookRateActivity extends Activity implements java.io.Serializable {

    /**

    private static final long serialVersionUID = 1L;
    public final static String FIRST_NAME_MESSAGE = "com.zombiecatandroidapp.MESSAGE";
    public final static String LAST_NAME_MESSAGE = "com.zombiecatandroidapp.MESSAGE";
    public final static String COMPANY_NAME_CHEF_COOK_MESSAGE = "com.zombiecatandroidapp.MESSAGE";
    public final static String COMPANY_ADDRESS_CHEF_COOK_MESSAGE = "com.zombiecatandroidapp.MESSAGE";

    public final static String COMPANY_STATE_CHEF_COOK_MESSAGE = "com.zombiecatandroidapp.MESSAGE";
    public final static String COMPANY_ZIP_CHEF_COOK_MESSAGE = "com.zombiecatandroidapp.MESSAGE";
    public final static String FOOD_RATE_CHEf_COOK_BAR_MESSAGE = "com.zombiecatandroidapp.MESSAGE";
    public final static String FILE_NAME = "C:\\Users\\Cassey\\AppData\\Local\\Development\\ProjectFile\\ChefCookRating.ser";
    ChefCook person = new ChefCook();

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

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.chef_cook_rate, menu);
        return true;
    }

    public void startSubmitDisplay(View view) {
        Intent intent = new Intent(this, DisplayInfoActivity.class);

        final EditText editText = (EditText) findViewById(R.id.first_name);
        String firstName = editText.getText().toString();

        final EditText editText1 = (EditText) findViewById(R.id.last_name);
        String lastName = editText1.getText().toString();

        final EditText editText2 = (EditText) findViewById(R.id.company_name_chef_cook);
        String companyNameChefCook = editText2.getText().toString();

        final EditText editText3 = (EditText) findViewById(R.id.company_address_chef_cook);
        String companyAddressChefCook = editText3.getText().toString();

        final EditText editText4 = (EditText) findViewById(R.id.company_city_chef_cook);
        String companyCityChefCook = editText4.getText().toString();

        final EditText editText5 = (EditText) findViewById(R.id.company_state_chef_cook);
        String companyStateChefCook = editText5.getText().toString();

        final EditText editText6 = (EditText) findViewById(R.id.company_zip_chef_cook);
        String companyZipChefCook = editText6.getText().toString();
        int companyZipChefCookConvert = Integer.parseInt(companyZipChefCook);

        RatingBar ratingbar = (RatingBar) findViewById(R.id.food_rate_chef_cook_bar);
        String foodRateChefCookBar = String.valueOf(ratingbar.getRating());
        int foodRateChefCookBarConvert = Integer.parseInt(foodRateChefCookBar);

        person.setFirstName(firstName);
        person.setLastName(lastName);
        person.setCompanyName(companyNameChefCook);
        person.setCompanyAddress(companyAddressChefCook);
        person.setCompanyCity(companyCityChefCook);
        person.setCompanyState(companyStateChefCook);
        person.setCompanyZip(companyZipChefCookConvert);
        person.setRating(firstName, lastName, foodRateChefCookBarConvert, 1);

        saveChefCook(person);

        startActivity(intent);
    }

    public void saveChefCook(ChefCook person) {
        try{
             // Serialize data object to a file
             ObjectOutputStream fileOut = new ObjectOutputStream(new FileOutputStream("FILE_NAME"));
             fileOut.writeObject(person);
             fileOut.close();
        } catch (IOException e) {
        }
    }
}

下一个活动看起来像这样。     包com.zombiecatandroidapp; 

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;
import android.content.Intent;

public class DisplayInfoActivity extends Activity {

    TextView textView3 = null;
    TextView textView4 = null;

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

        Intent intent = getIntent();
        String message = intent.getStringExtra(ChefCookRateActivity.FIRST_NAME_MESSAGE);
        message += intent.getStringExtra(ChefCookRateActivity.LAST_NAME_MESSAGE);
        String message2 = intent.getStringExtra(ChefCookRateActivity.COMPANY_NAME_CHEF_COOK_MESSAGE);
        String message3 = intent.getStringExtra(ChefCookRateActivity.COMPANY_ADDRESS_CHEF_COOK_MESSAGE);
        String message4 = intent.getStringExtra(ChefCookRateActivity.COMPANY_CITY_CHEF_COOK_MESSAGE);
        message4 += intent.getStringExtra(ChefCookRateActivity.COMPANY_STATE_CHEF_COOK_MESSAGE);
        message4 += intent.getStringExtra(ChefCookRateActivity.COMPANY_ZIP_CHEF_COOK_MESSAGE);
        String message5 = intent.getStringExtra(ChefCookRateActivity.FOOD_RATE_CHEf_COOK_BAR_MESSAGE);

        // Create the text view
        TextView textView = new TextView(this);
        textView.setText(message);

        TextView textView2 = new TextView(this);
        textView.setText(message2);

        TextView textView3 = new TextView(this);
        textView.setText(message3);

        TextView textView4 = new TextView(this);
        textView.setText(message4);


        TextView textView5 = new TextView(this);
        textView.setText(message5);


        // Set the text view as the activity layout
        setContentView(textView);
        if(textView2 != null) {
            setContentView(textView2);
        }        
        if(textView3 != null) {
            setContentView(textView3);
        }
        if(textView4 != null) {
            setContentView(textView4);
        }
        setContentView(textView5);

}


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.display_info, menu);
        return true;
    }

}

我尚未编写此活动的显示活动，因为当我尝试至少延长此活动时，我的模拟器会因活动线程错误而崩溃。有关未找到来源的事情。

同样，我还没有写过这个的显示活动，因为当我尝试至少延长这个活动时，我的模拟器会因为活动线程错误而崩溃。有关未找到来源的事情。

我尝试了第四个版本，看起来像这样。

再一次，它只是停止我的模拟器。

有人可以帮忙吗？

1 个答案:

答案 0 :(得分：0)

我不完全明白确切的问题是什么，但无论你做什么，都不会尝试序列化整个活动。

我会改为使Person可序列化，并将其提供给第二个活动的意图。 E.g：

intent.putSerializable(EXTRA_PERSON, person);
startActivity(intent);
