在Android开发中，对日志的调试中可能有着非常众多的花样，这里介绍的是最常用的做法，显示日志的类名和行数。
参考代码如下：
|
public
final
class
Ln
{
private
static
boolean
isDebug;
private
Ln
() {
}
public
static
void
init
(Context context) {
ApplicationInfo info = context.getApplicationInfo();
//
判断
APP
是否处在调试模式
isDebug = (info.flags & ApplicationInfo.FLAG_DEBUGGABLE) !=
0
;
}
public
static
boolean
isDebugEnabled
() {
return
isDebug;
}
public
static
void
d
(Object s) {
if
(isDebugEnabled()) {
Log.println(Log.DEBUG, getTag(),
" "
+ String.valueOf(s));
}
}
public
static
void
e
(Object s) {
Log.println(Log.ERROR, getTag(),
" "
+ String.valueOf(s));
}
private
static
String
getTag
() {
final
int
skipDepth =
4
;
// skip 6 stackframes to find the location where this was called
if
(isDebugEnabled()) {
StackTraceElement[] elements = Thread.currentThread().getStackTrace();
final
StackTraceElement trace = elements[skipDepth];
return
trace.getFileName() + trace.getLineNumber();
}
return
""
;
}
}
