传递整数活动和意图的机器人之间始终是造成零/空 [英] Passing Integer Between Activities and Intents in Android Is Always Resulting in Zero / Null

问题描述

我试图通过从我的主页活动两个整数（经度和纬度）到包含谷歌地图的一个实例，否则将标记的纬度和长提供的第二个活动。我的难题是，当我找回包的Map_Page活动我通过这个整数是始终为0，这是默认的，当他们空。有谁看到什么错得离谱？

我有以下的存储在一个按钮，单击OnClick方法。

 捆绑dataBundle =新包（）;

dataBundle.putInt（LatValue，39485000）;
dataBundle.putInt（的longValue，-80142777）;
意图myIntent =新意图（）;
myIntent.setClassName（com.name.tlc，com.name.tlc.map_page）;
myIntent.putExtras（dataBundle）;
startActivity（myIntent）;
 

---

然后在我的map_page活动，我有以下的的onCreate回暖数据。

 捆绑额外= getIntent（）getExtras（）。
的System.out.println（获取意图做）;
如果（临时演员！= NULL）
{
    的System.out.println（让我们的价值观）;
    INT latValue = extras.getInt（latValue）;
    INT的longValue = extras.getInt（的longValue）;

    的System.out.println（latValue =+ latValue +的longValue =+的longValue）;

}
 

解决方案

 的System.out.println（让我们的价值观）;
INT latValue = extras.getInt（latValue）;
INT的longValue = extras.getInt（的longValue）;
 

不一样的

  myIntent.putExtra（LatValue，（INT）39485000）;
myIntent.putExtra（的longValue，（int）的-80142777）;
 

此外，它可能是因为你不守诚信的整个code一模一样的名字。 Java和Android的SDK是区分大小写

I'm attempting to pass two integers from my Main Page activity (a latitude and longitude) to a second activity that contains an instance of Google Maps that will place a marker at the lat and long provided. My conundrum is that when I retrieve the bundle in the Map_Page activity the integers I passed are always 0, which is the default when they are Null. Does anyone see anything glaringly wrong?

I have the following stored in a button click OnClick method.

Bundle dataBundle = new Bundle();

dataBundle.putInt("LatValue", 39485000);
dataBundle.putInt("LongValue", -80142777);
Intent myIntent = new Intent();
myIntent.setClassName("com.name.tlc", "com.name.tlc.map_page");
myIntent.putExtras(dataBundle);
startActivity(myIntent);

---

Then in my map_page activity I have the following in onCreate to pick up the data.

Bundle extras = getIntent().getExtras(); 
System.out.println("Get Intent done");
if(extras !=null)
{
    System.out.println("Let's get the values");
    int latValue = extras.getInt("latValue");
    int longValue = extras.getInt("longValue");

    System.out.println("latValue = " + latValue + " longValue = " + longValue);

}

解决方案

System.out.println("Let's get the values");
int latValue = extras.getInt("latValue");
int longValue = extras.getInt("longValue");

Not the same as

myIntent.putExtra("LatValue", (int)39485000);
myIntent.putExtra("LongValue", (int)-80142777);

Also it might be because you do not keep the name of the Int exactly the same throughout your code. Java and the Android SDK are Case-sensitive
