Android 定制自己的日志工具

public class ZLog {

    private static final String TAG = "MyApplication";
//    private static boolean isOpenD = Log.isLoggable(TAG, Log.DEBUG);
    private static boolean isOpenD = true;

    public static void d(String tag, String msg){
        if(isOpenD){
            StackTraceElement element = (new Exception()).getStackTrace()[1];
            StringBuilder stringBuilder = new StringBuilder(" [ ")
                    .append(element.getFileName())
                    .append(" | ")
                    .append(element.getLineNumber())
                    .append(" | ")
                    .append(element.getMethodName() + "( )")
                    .append(" ] ");
            Log.d(TAG +" : " + stringBuilder.toString() + tag, msg);
        }
    }
}

效果如下：
