如何设置文本的整数，并得到INT没有得到错误 [英] how to set text an integer and get int without getting error

问题描述

这是code我在得到整数意图使用。字符串GET意图工作正常，并表现不错，但是当我把整数i得到一个强制关闭错误。我可能是错在这里做一些事情。这是code：

 包kfc.project;进口android.app.Activity;
进口android.content.Intent;
进口android.os.Bundle;
进口android.widget.EditText;
进口android.widget.TextView;公共类产品详情延伸活动{    @覆盖
    保护无效的onCreate（捆绑包）{
        // TODO自动生成方法存根
        super.onCreate（包）;
        的setContentView（R.layout.productdetail）;
        //东西拿到意图
        意向receivedIntent = getIntent（）;
        字符串产品名称= receivedIntent.getStringExtra（名称）;
        INT productCalories = receivedIntent.getIntExtra（卡路里，0）;            / *意向意图=新意图（ProductListView.this，productdetail.class）;
            intent.putExtra（名，product.getName（））;
            intent.putExtra（卡路里，product.getCalories（））;
            intent.putExtra（份量，product.getServingSize（））;
            intent.putExtra（胖，product.getFat（））;
            intent.putExtra（饱和脂肪，product.getSaturatedFat（））;
            intent.putExtra（反式脂肪，product.getTransFat（））;
            intent.putExtra（胆固醇，product.getCholesterol（））;
            intent.putExtra（钠，product.getSodium（））;
            intent.putExtra（碳水化合物，product.getCarbs（））;
            intent.putExtra（纤维，product.getFiber（））;
            intent.putExtra（糖，product.getSugar（））;
            intent.putExtra（蛋白质，product.getProtein（））;
            intent.putExtra（维生素A，product.getVitaminA（））;
            intent.putExtra（维生素C，product.getVitaminC（））;
            intent.putExtra（钙，product.getCalcium（））;
            intent.putExtra（铁，product.getIron（））; * /
        捆绑额外= getIntent（）getExtras（）。        字符串名称= extras.getString（名称）;        如果（名字！= NULL）{
            TextView的文本1 =（的TextView）findViewById（R.id.servingsize）;
            text1.setText（产品名称）;        }
        // INT热量= extras.getInt（卡路里）;            TextView的文本1 =（的TextView）findViewById（R.id.calories）;
            text1.setText（productCalories）;
        / *
        意向意图= getIntent（）;
        字符串str = intent.getStringExtra（名称）; * /    }}
 

解决方案

 的TextView的text1 =（的TextView）findViewById（R.id.calories）;
                text1.setText（+ productCalories）;
//要么字符串s =将String.valueOf（productCalories）;
 text1.setText（多个）;
 

This is the code i used in getting the intent for integer. The String get intent works fine and displays well but when i put the integer i get a force close error. I might be doing something wrong here. This is the code:

package kfc.project;

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

public class productdetail extends Activity{

    @Override
    protected void onCreate(Bundle bundle) {
        // TODO Auto-generated method stub
        super.onCreate(bundle);
        setContentView(R.layout.productdetail);
        //stuff to get intent
        Intent receivedIntent = getIntent();


        String productName = receivedIntent.getStringExtra("name");
        int productCalories = receivedIntent.getIntExtra("calories",0);

            /*Intent intent = new Intent(ProductListView.this, productdetail.class);
            intent.putExtra("name",product.getName());
            intent.putExtra("calories", product.getCalories());
            intent.putExtra("serving size", product.getServingSize());
            intent.putExtra("fat", product.getFat());
            intent.putExtra("saturated fat", product.getSaturatedFat());
            intent.putExtra("trans fat", product.getTransFat());
            intent.putExtra("cholesterol", product.getCholesterol());
            intent.putExtra("sodium", product.getSodium());
            intent.putExtra("carbs", product.getCarbs());
            intent.putExtra("fiber", product.getFiber());
            intent.putExtra("sugar", product.getSugar());
            intent.putExtra("protein", product.getProtein());
            intent.putExtra("vitamina", product.getVitaminA());
            intent.putExtra("vitaminc", product.getVitaminC());
            intent.putExtra("calcium", product.getCalcium());
            intent.putExtra("iron", product.getIron());*/
        Bundle extras = getIntent().getExtras();

        String name = extras.getString("name");

        if (name != null) {
            TextView text1 = (TextView) findViewById(R.id.servingsize);
            text1.setText(productName);

        }
        //int calories = extras.getInt("calories");

            TextView text1 = (TextView) findViewById(R.id.calories);
            text1.setText(productCalories);


        /*
        Intent intent = getIntent();
        String str = intent.getStringExtra("name");*/

    }





}

解决方案

    TextView text1 = (TextView) findViewById(R.id.calories);
                text1.setText(""+productCalories);
//or

String s = String.valueOf(productCalories);
 text1.setText(s);
