我正在尝试获取用于选择联系人并检索电话号码的代码。我发现一段代码在模拟器（android 版本 2.3.3）和我兄弟的手机（果冻豆）上运行良好，但在我自己的设备上运行良好（android 2.3.4）
这是代码：转到联系人
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
startActivityForResult(intent, 1);
}
从联系人回来时：
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (data != null) {
Uri uri = data.getData();
if (uri != null) {
Cursor c = null;
try {
c = getContentResolver().query(uri, new String[]{ContactsContract.CommonDataKinds.Phone.NUMBER},
null, null, null);
if (c != null && c.moveToFirst()) {
String number = c.getString(0);
//int type = c.getInt(1);
showSelectedNumber(0, number);
}
} finally {
if (c != null) {
c.close();
}
}
}
}
}
public void showSelectedNumber(int type, String number) {
Toast.makeText(this,number, Toast.LENGTH_LONG).show();
}
同样，这适用于模拟器（android 2.3.4）和果冻豆，但不适用于我的设备（android 2.3.5）
这是从日志中得出的：
