Android 2.1 How to get Phone Numbers of contacts
提问by Brandon Delany
I am new to Android and have been working on an app that needs to get all of the user's contact's phone numbers. Apparently the code I have does not work with the 2.1 SDK. So far here is the code I am using:
我是 Android 新手，一直在开发一个需要获取用户所有联系人电话号码的应用程序。显然，我拥有的代码不适用于 2.1 SDK。到目前为止，这是我正在使用的代码：
String[] projection = new String[] { Phone.NUMBER };
Cursor c = managedQuery( Phone.CONTENT_URI, projection, null, null, null );
int colIndex = -1;
try {
colIndex = c.getColumnIndexOrThrow( Phone.NUMBER );
} catch( Exception e ) {
print( e.getMessage() );
}
print( "Column Index = " + colIndex );
//count is equal to 3
for( int i = 0; i < count; i++ ){
try {
print( c.getString( 2 ) ); //the 2 used to be colIndex
} catch ( Exception e ) {
print( e.getMessage() );
}
}
It seems that no matter what I pass into c.getString() it keeps telling me that I passed in -1. But I even hardcoded the 2, and it says the same thing. Any help would be much appreciated.
似乎无论我传入 c.getString() 什么，它一直告诉我我传入了 -1。但我什至对 2 进行了硬编码，它说的是同样的事情。任何帮助将非常感激。
