Android——Log显示日志
显示效果如下：
具体代码实现：
public class LogUtil { private static String TAG = "zss"; private static boolean isDebug = true; public static final int DEBUG = 3; public static final int ERROR = 6; public static void init(boolean debug, String tag) { isDebug = debug; TAG = tag; } public static void logDebug(String msg, Object... params) { logDebug(null, msg, params); } public static void logDebug(String tag, String msg, Object[] params) { if (!isDebug) return; LogText.log(getFinalTag(tag), String.format(msg, params), DEBUG); } public static void logError(Throwable e) { logError(null, e); } public static void logError(String tag, Throwable e) { if (!isDebug) return; LogText.log(getFinalTag(tag), String.format("%s", e.toString()), ERROR, e); } public static void logError(String msg, Object... params) { logError(null, msg, params, null); } public static void logError(String tag, String msg, Object[] params, Throwable th) { if (!isDebug) return; LogText.log(getFinalTag(tag), String.format(msg, params), ERROR, th); } private static String getFinalTag(String tag) { if (!TextUtils.isEmpty(tag)) { return tag; } return TAG; } private static class LogText { private static final char TOP_LEFT_CORNER = '┌'; private static final char BOTTOM_LEFT_CORNER = '└'; private static final char MIDDLE_CORNER = '├'; private static final char HORIZONTAL_LINE = '│'; private static final String DOUBLE_DIVIDER = "────────────────────────────────────────────────────────"; private static final String SINGLE_DIVIDER = "┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄┄"; private static final String TOP_BORDER = TOP_LEFT_CORNER + DOUBLE_DIVIDER + DOUBLE_DIVIDER; private static final String BOTTOM_BORDER = BOTTOM_LEFT_CORNER + DOUBLE_DIVIDER + DOUBLE_DIVIDER; private static final String MIDDLE_BORDER = MIDDLE_CORNER + SINGLE_DIVIDER + SINGLE_DIVIDER; private String mTag; public LogText(String mTag) { this.mTag = mTag; } public static void log(String tag, String content, int debugIndex) { log(tag, content, debugIndex, null); } public static void log(String tag, String content, int debugIndex, Throwable th) { LogText logText = new LogText(tag); logText.setup(content, debugIndex, th); } public void setup(String content, int debugType, Throwable th) { setUpHeader(debugType); setUpContent(content, debugType, th); setUpFooter(debugType); } private void setUpHeader(int debugType) { Log.println(debugType, mTag, TOP_BORDER); } private void setUpFooter(int debugType) { Log.println(debugType, mTag, BOTTOM_BORDER); } public void setUpContent(String content, int debugType, Throwable th) { StackTraceElement targetStackTraceElement = getTargetStackTraceElement(); Log.println(debugType, mTag, HORIZONTAL_LINE + " " + targetStackTraceElement.getClassName() + "." + targetStackTraceElement.getMethodName() + " (" + targetStackTraceElement.getFileName() + ":" + targetStackTraceElement.getLineNumber() + ")"); Log.println(debugType, mTag, MIDDLE_BORDER); Log.println(debugType, mTag, HORIZONTAL_LINE + " " + content); if ((null != th) && (th.getStackTrace().length > 0)) { Log.println(debugType, mTag, HORIZONTAL_LINE + " " + th.getStackTrace()[0].toString()); } } private StackTraceElement getTargetStackTraceElement() { // find the target invoked method StackTraceElement targetStackTrace = null; boolean shouldTrace = false; StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace(); for (StackTraceElement stackTraceElement : stackTrace) { boolean isLogMethod = stackTraceElement.getClassName().equals(LogUtil.class.getName()); if (shouldTrace && !isLogMethod) { targetStackTrace = stackTraceElement; break; } shouldTrace = isLogMethod; } return targetStackTrace; } }}使用方式：
LogUtil.logDebug("======xxxxx====="); LogUtil.logError("======sssss======"); LogModelTest modelTest = new LogModelTest(1, "zss"); LogUtil.logDebug("新添加的内容：%s", modelTest.toString()); try { String aa = null; aa.toString(); } catch (Exception e) { LogUtil.logError(e.toString()); }参考地址：
