本文整理了Java中android.database.Cursor.getInt()方法的一些代码示例，展示了Cursor.getInt()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Cursor.getInt()方法的具体详情如下：
包路径：android.database.Cursor
类名称：Cursor
方法名：getInt

Cursor.getInt介绍

[英]Returns the value of the requested column as an int.

The result and whether this method throws an exception when the column value is null, the column type is not an integral type, or the integer value is outside the range [Integer.MIN_VALUE, Integer.MAX_VALUE] is implementation-defined.
[中]以int形式返回请求列的值。
结果以及当列值为null、列类型不是整数类型或整数值超出范围Integer.MIN_VALUE、Integer.MAX_VALUE时，此方法是否引发异常是由实现定义的。

Cursor countCursor = getContentResolver().query(CONTENT_URI,
       new String[] {"count(*) AS count"},
       null,
       null,
       null);
   countCursor.moveToFirst();
   int count = countCursor.getInt(0);

String selection = "_id = "+id;
Uri uri = Uri.parse("content://sms");
Cursor cursor = contentResolver.query(uri, null, selection, null, null);
String phone = cursor.getString(cursor.getColumnIndex("address"));
int type = cursor.getInt(cursor.getColumnIndex("type"));// 2 = sent, etc.
String date = cursor.getString(cursor.getColumnIndex("date"));
String body = cursor.getString(cursor.getColumnIndex("body"));
