DebugTool 工具类

public class DebugTools {public boolean isDebug = true;private static DebugTools debug;private DebugTools(){}public static DebugTools getDebug(){if (debug == null)debug = new DebugTools();return debug;}public void debug_v(String tag, String content){if (isDebug){Log.v(tag, content);}}public void debug_d(String tag, String content){if (isDebug){Log.d(tag, content);}}public void debug_e(String tag, String content){if (isDebug){Log.e(tag, content);}}}

用法：

DebugTools.getDebug().debug_v(CommonData.DEBUG_TAG, "");

不想打印了就设置isDebug为false.
